The animation moves the blocks between four preset positions. - - The example consists of the following classes: - - \list - \li \c StateSwitcher inherits QState and can add - \c {StateSwitchTransition}s to other states. - When entered, it will randomly transition to one of these - states. - \li \c StateSwitchTransition is a custom transition that - triggers on \c{StateSwitchEvent}s. - \li \c StateSwitchEvent is a QEvent that triggers \c{StateSwitchTransition}s. - \li \c QGraphicsRectWidget is a QGraphicsWidget that simply - paints its background in a solid \l{Qt::}{blue} color. - \endlist - - The blocks are instances of \c QGraphicsRectWidget and are - animated in a QGraphicsScene. We do this by building a state - graph, which we insert animations into. The graph is then executed - in a QStateMachine. All this is done in \c main(). - Let's look at the \c main() function first. - - \section1 The \c main() Function - - After QApplication has been initialized, we set up the - QGraphicsScene with its \c{QGraphicsRectWidget}s. - - \snippet animation/moveblocks/main.cpp 1 - - After adding the scene to a QGraphicsView, it is time to build the - state graph. Let's first look at a statechart of what we are - trying to build. - - \image move-blocks-chart.png - - Note that the \c group has seven sub states, but we have only - included three of them in the diagram. The code that builds this - graph will be examined line-by-line, and will show how the graph - works. First off, we construct the \c group state: - - \snippet animation/moveblocks/main.cpp 2 - - The timer is used to add a delay between each time the blocks are - moved. The timer is started when \c group is entered. As we will - see later, \c group has a transition back to the \c StateSwitcher - when the timer times out. \c group is the initial state in the - machine, so an animation will be scheduled when the example is - started. - - \snippet animation/moveblocks/main.cpp 3 - \dots - \snippet animation/moveblocks/main.cpp 4 - - \c createGeometryState() returns a QState that will set the - geometry of our items upon entry. It also assigns \c group as the - parent of this state. - - A QPropertyAnimation inserted into a transition will use the - values assigned to a QState (with QState::assignProperty()), i.e., - the animation will interpolate between the current values of the - properties and the values in the target state. We add animated - transitions to the state graph later. - - \snippet animation/moveblocks/main.cpp 5 - - We move the items in parallel. Each item is added to \c - animationGroup, which is the animation that is inserted into the - transitions. - - \snippet animation/moveblocks/main.cpp 6 - - The sequential animation group, \c subGroup, helps us insert a - delay between the animation of each item. - - \snippet animation/moveblocks/main.cpp 7 - \dots - \snippet animation/moveblocks/main.cpp 8 - - A StateSwitchTransition is added to the state switcher - in \c StateSwitcher::addState(). We also add the animation in this - function. Since QPropertyAnimation uses the values from the - states, we can insert the same QPropertyAnimation instance in all - \c {StateSwitchTransition}s. - - As mentioned previously, we add a transition to the state switcher - that triggers when the timer times out. - - \snippet animation/moveblocks/main.cpp 9 - - Finally, we can create the state machine, add our initial state, - and start execution of the state graph. - - \section2 The \c createGeometryState() Function - - In \c createGeometryState(), we set up the geometry for each - graphics item. - - \snippet animation/moveblocks/main.cpp 13 - - As mentioned before, QAbstractTransition will set up an animation - added with \l{QAbstractTransition::}{addAnimation()} using - property values set with \l{QState::}{assignProperty()}. - - \section1 The StateSwitcher Class - - \c StateSwitcher has state switch transitions to each \l{QState}s - we created with \c createGeometryState(). Its job is to transition - to one of these states at random when it is entered. - - All functions in \c StateSwitcher are inlined. We'll step through - its definition. - - \snippet animation/moveblocks/main.cpp 10 - - \c StateSwitcher is a state designed for a particular purpose and - will always be a top-level state.

We assign a number to each state - added. This number is given to both a StateSwitchTransition and to - StateSwitchEvents. As we have seen, state switch events will - trigger a transition with the same number. - - \section1 The StateSwitchTransition Class - - \c StateSwitchTransition inherits QAbstractTransition and triggers - on \c{StateSwitchEvent}s. It contains only inline functions, so - let's take a look at its \l{QAbstractTransition::}{eventTest()} - function, which is the only function that we define.. - - \snippet animation/moveblocks/main.cpp 14 - - \c eventTest is called by QStateMachine when it checks whether a - transition should be triggered--a return value of true means that - it will.

Pressing enter - will flip the pad around and reveal its back side, which has a form - embedded into a QGraphicsProxyWidget. You can interact with the form, and - press the enter key to flip back to the front side of the pad at any time. - - Graphics View provides the QGraphicsScene class for managing and - interacting with a large number of custom-made 2D graphical items derived - from the QGraphicsItem class, and a QGraphicsView widget for visualizing - the items, with support for zooming and rotation. - - This example consists of a \c RoundRectItem class, a \c FlippablePad class, - a \c PadNavigator class, a \c SplashItem class, and a \c main() function. - - \section1 RoundRectItem Class Definition - - The \c RoundRectItem class is used by itself to display the icons on the - pad, and as a base class for \c FlippablePad, the class for the pad itself. - The role of the class is to paint a round rectangle of a specified size and - gradient color, and optionally to paint a pixmap icon on top. To support \c - FlippablePad it also allows filling its contents with a plain window - background color. - - Let's start by reviewing the \c RoundRectItem class declaration. - - \snippet graphicsview/padnavigator/roundrectitem.h 0 - - \c RoundRectItem inherits QGraphicsObject, which makes it easy to control - its properties using QPropertyAnimation. Its constructor takes a rectangle - to determine its bounds, and a color. - - Besides implementing the mandatory \l{QGraphicsItem::paint()}{paint()} and - \l{QGraphicsItem::boundingRect()}{boundingRect()} pure virtual functions, - it also provides the \c pixmap and \c fill properties. - - The \c pixmap property sets an optional pixmap that is drawn on top of the - round rectangle. The \c fill property will, when true, fill the round - rectangle contents with a fixed QPalette::Window background color. - Otherwise the contents are filled using a gradient based on the color - passed to \c RoundRectItem's constructor. - - \snippet graphicsview/padnavigator/roundrectitem.h 1 - - The private data members are: - - \list - \li \c pix: The optional pixmap that is drawn on top of the rectangle. - \li \c fillRect: Corresponds to the \c fill property. - \li \c color: The configurable gradient color fill of the rectangle. - \li \c bounds: The bounds of the rectangle. - \li \c gradient: A precalculated gradient used to fill the rectangle. - \endlist - - We will now review the \c RoundRectItem implementation. Let's start by - looking at its constructor: - - \snippet graphicsview/padnavigator/roundrectitem.cpp 0 - - The constructor initializes its member variables and forwards the \c parent - argument to QGraphicsObject's constructor. It then constructs the linear - gradient that is used in \l{QGraphicsItem::paint()}{paint()} to draw the - round rectangle's gradient background. The linear gradient's starting point - is at the top-left corner of the bounds, and the end is at the bottom-left - corner. The start color is identical to the color passed as an argument, - and a slightly darker color is chosen for the final stop. - - We store this gradient as a member variable to avoid having to recreate the - gradient every time the item is repainted. - - Finally we set the cache mode - \l{QGraphicsItem::ItemCoordinateCache}{ItemCoordinateCache}. This mode - causes the item's rendering to be cached into an off-screen pixmap that - remains persistent as we move and transform the item. This mode is ideal - for this example, and works particularly well with OpenGL and OpenGL ES. - - \snippet graphicsview/padnavigator/roundrectitem.cpp 1 - - The \c pixmap property implementation simple returns the member pixmap, or - sets it and then calls \l{QGraphicsItem::update()}{update()}. - - \snippet graphicsview/padnavigator/roundrectitem.cpp 2 - - As the \l{QGraphicsItem::paint()}{paint()} implementation below draws a - simple drop shadow down and to the right of the item, we return a slightly - adjusted rectangle from \l{QGraphicsItem::boundingRect()}{boundingRect()}. - - \snippet graphicsview/padnavigator/roundrectitem.cpp 3 - - The \l{QGraphicsItem::paint()}{paint()} implementation starts by rendering - a semi transparent black round rectangle drop shadow, two units down and to - the right of the main item. - - \snippet graphicsview/padnavigator/roundrectitem.cpp 4 - - We then draw the "foreground" round rectangle itself. The fill depends on - the \c fill property; if true, we will with a plain QPalette::Window color. - We get the current brush from QApplication::palette(). We assign a single - unit wide pen for the stroke, assign the brush, and then draw the - rectangle. - - \snippet graphicsview/padnavigator/roundrectitem.cpp 5 - - If a pixmap has been assigned to the \e pixmap property, we draw this - pixmap in the center of the rectangle item. The pixmaps are scaled to match - the size of the icons; in arguably a better approach would have been to - store the icons with the right size in the first places. - - \snippet graphicsview/padnavigator/roundrectitem.cpp 6 - - Finally, for completeness we include the \c fill property implementation. - It returns the \c fill member variable's value, and when assigned to, it - calls \l{QGraphicsItem::update()}{update()}. - - As mentioned already, \c RoundRectItem is the base class for \c - FlippablePad, which is the class representing the tilting pad itself. We - will proceed to reviewing \c FlippablePad. - - \section1 FlippablePad Class Definition - - \c FlippablePad is, in addition to its inherited \c RoundRectItem - responsibilities, responsible for creating and managing a grid of icons. - - \snippet graphicsview/padnavigator/flippablepad.h 0 - - Its declaration is very simple: It inherits \c RoundRectItem and does not - need any special polymorphic behavior. It's suitable to declare its own - constructor, and a getter-function that allows \c PadNavigator to access - the icons in the grid by (row, column). - - The example has no "real" behavior or logic of any kind, and because of - that, the icons do not need to provide any \e behavior or special - interactions management. In a real application, however, it would be - natural for the \c FlippablePad and its icons to handle more of the - navigation logic. In this example, we have chosen to leave this to - the \c PadNavigator class, which we will get back to below. - - We will now review the \c FlippablePad implementation. This implementation - starts with two helper functions: \c boundsFromSize() and \c - posForLocation(): - - \snippet graphicsview/padnavigator/flippablepad.cpp 0 - - \c boundsForSize() takes a QSize argument, and returns the bounding - rectangle of the flippable pad item. The QSize determines how many rows and - columns the icon grid should have. Each icon is given 150x150 units of - space, and this determines the bounds. - - \snippet graphicsview/padnavigator/flippablepad.cpp 1 - - \c posForLocation() returns the position of an icon given its row and - column position. Like \c boundsForSize(), the function assumes each icon is - given 150x150 units of space, and that all icons are centered around the - flippable pad item's origin (0, 0). - - \snippet graphicsview/padnavigator/flippablepad.cpp 2 - - The \c FlippablePad constructor passes suitable bounds (using \c - boundsForSize()) and specific color to \c RoundRectItem's constructor. - - \snippet graphicsview/padnavigator/flippablepad.cpp 3 - - It then loads pixmaps from compiled-in resources to use for its icons. - QDirIterator is very useful in this context, as it allows us to fetch all - resource "*.png" files inside the \c :/images directory without explicitly - naming the files. - - We also make sure not to load more pixmaps than we need. - - \snippet graphicsview/padnavigator/flippablepad.cpp 4 - - Now that we have the pixmaps, we can create icons, position then and assign - pixmaps. We start by finding a suitable size and color for the icons, and - initializing a convenient grid structure for storing the icons. This \c - iconGrid is also used later to find the icon for a specific (column, row) - location. - - For each row and column in our grid, we proceed to constructing each icon - as an instance of \c RoundRectItem. The item is placed by using the \c - posForLocation() helper function. To make room for the slip-behind - selection item, we give each icon a \l{QGraphicsItem::zValue()}{Z-value} of - 1. The pixmaps are distributed to the icons in round-robin fasion. - - Again, this approach is only suitable for example purposes. In a real-life - application where each icon represents a specific action, it would be more - natural to assign the pixmaps directly, or that the icons themselves - provide suitable pixmaps. - - \snippet graphicsview/padnavigator/flippablepad.cpp 5 - - Finally, the \c iconAt() function returns a pointer to the icon at a - specific row and column. It makes a somewhat bold assumption that the input - is valid, which is fair because the \c PadNavigator class only calls this - function with correct input. - - We will now review the \c SplashItem class. - - \section1 SplashItem Class Definition - - The \c SplashItem class represents the "splash window", a semitransparent - white overlay with text that appears immediately after the application has - started, and disappears after pressing any key. The animation is controlled - by \c PadNavigator; this class is very simple by itself. - - \snippet graphicsview/padnavigator/splashitem.h 0 - - The class declaration shows that \c SplashItem inherits QGraphicsObject to - allow it to be controlled by QPropertyAnimation. It reimplements the - mandatory \l{QGraphicsItem::paint()}{paint()} and - \l{QGraphicsItem::boundingRect()}{boundingRect()} pure virtual functions, - and keeps a \c text member variable which will contain the information text - displayed on this splash item. - - Let's look at its implementation. - - \snippet graphicsview/padnavigator/splashitem.cpp 0 - - The constructor forwards to QGraphicsObject as expected, assigns a text - message to the \c text member variable, and enables - \l{QGraphicsItem::DeviceCoordinateCache}{DeviceCoordinateCache}. This cache - mode is suitable because the splash item only moves and is never - transformed, and because it contains text, it's important that it has a - pixel perfect visual appearance (in constrast to - \l{QGraphicsItem::ItemCoordinateCache}{ItemCoordinateCache}, where the - visual appearance is not as good). - - We use caching to avoid having to relayout and rerender the text for each - frame. An alterative approach would be to use the new QStaticText class. - - \snippet graphicsview/padnavigator/splashitem.cpp 1 - - \c SplashItem's bounding rectangle is fixed at (400x175). - - \snippet graphicsview/padnavigator/splashitem.cpp 2 - - The \l{QGraphicsItem::paint()}{paint()} implementation draws a clipped - round rectangle with a thick 2-unit border and a semi-transparent white - background. It proceeds to finding a suitable text area by adjusting the - splash item's bounding rectangle with 10 units in each side. The text is - rendered inside this rectangle, with top-left alignment, and with word - wrapping enabled. - - The main class now remains. We will proceed to reviewing \c PadNavigator. - - \section1 PadNavigator Class Definition - - \c PadNavigator represents the main window of our Pad Navigator Example - application. It creates and controls a somewhat complex state machine, and - several animations. Its class declaration is very simple: - - \snippet graphicsview/padnavigator/padnavigator.h 0 - - It inherits QGraphicsView and reimplements only one function: - \l{QGraphicsView::resizeEvent()}{resizeEvent()}, to ensure the scene is - scaled to fit inside the view when resizing the main window. - - The \c PadNavigator constructor takes a QSize argument that determines the - number or rows and columns in the grid. - - It also keeps a private member instance, \c form, which is the generated - code for the pad's back side item's QGraphicsProxyWidget-embedded form. - - \snippet graphicsview/padnavigator/padnavigator.cpp 0 - - \c PadNavigator's constructor is a bit long. In short, its job is to create - all items, including the \c FlippablePad, the \c SplashItem and the - QGraphicsProxyWidget \c backItem, and then to set up all animations, states - and transitions that control the behavior of the application. - - It starts out simple, by forwarding to QGraphicsView's constructor. - - \snippet graphicsview/padnavigator/padnavigator.cpp 1 - - The first item to be created is \c SplashItem. This is going to be a top-level - item in the scene, next to \c FlippablePad, and stacked on top of it, so we - assign it a \l{QGraphicsItem::zValue()}{Z-value} of 1. - - \snippet graphicsview/padnavigator/padnavigator.cpp 2 - - Now we construct the \c FlippablePad item, passing its column-row count to - its constructor. - - The pad is controlled by three transformations, and we create one - QGraphicsRotation object for each of these. - - \list - \li \c flipRotation: Rotates the grid around its Qt::YAxis. This rotation is - animated from 0 to 180, and eventually back, when enter is pressed on the - keyboard, flipping the pad around. - \li \c xRotation: Rotates the grid around its Qt::XAxis. This is used to - tilt the pad vertically corresponding to which item is currently selected. - This way, the selected item is always kept in front. - \li \c yRotation: Rotates the grid around its Qt::YAxis. This is used to - tilt the pad horizontally corresponding to which item is selected. This - way, the selected item is always kept in front. - \endlist - - The combination of all three rotations is assigned via - QGraphicsItem::setTransformations(). - - \snippet graphicsview/padnavigator/padnavigator.cpp 3 - - Now we construct the QGraphicsProxyWidget-embedded \c backItem. The proxy - widget is created as a child of the pad. We create a new QWidget and - populate it with the \c form member. To ensure the \c hostName line edit is - the first to receive input focus when this item is shown, we call - \l{QWidget::setFocus()}{setFocus()} immediately. This will not give the - widget focus right away; it will only prepare the item to automatically - receive focus once it is shown. - - The QWidget based form is embedded into the proxy widget. The proxy is - hidden initially; we only want to show it when the pad is rotated at least - 90 degrees, and we also rotate the proxy itself by 180 degrees. This way we - give the impression that the proxy widget is "behind" the flipped pad, when - in fact, it's actually \e{on top of it}. - - We enable \l{QGraphicsItem::ItemCoordinateCache}{ItemCoordinateCache} to - ensure the flip animation can run smoothly. - - \snippet graphicsview/padnavigator/padnavigator.cpp 4 - - We now create the selection item. This is simply another instance of \c - RoundRectItem that is slightly larger than the icons on the pad. We create - it as an immediate child of the \c FlippablePad, so the selection item is a - sibling to all the icons. By giving it a - \l{QGraphicsItem::zValue()}{Z-value} of 0.5 we ensure it will slide between - the pad and its icons. - - What follows now is a series of animation initializations. - - \snippet graphicsview/padnavigator/padnavigator.cpp 5 - - We begin with the animations that apply to the splash item. The first - animation, \c smoothSplashMove, ensures that the "y" property of \c splash - will be animated with a 250-millisecond duration - \l{QEasingCurve::InQuad}{InQuad} easing function. \c smoothSplashOpacity - ensures the opacity of \c splash eases in and out in 250 milliseconds. - - The values are assigned by \c PadNavigator's state machine, which is - created later. - - \snippet graphicsview/padnavigator/padnavigator.cpp 6 - - These are the animations that control the selection item's movement and the - \c xRotation and \c yRotation QGraphicsRotation objects that tilt the pad. - All animations have a duration of 125 milliseconds, and they all use the - \l{QEasingCurve::InOutQuad}{InOutQuad} easing function. - - \snippet graphicsview/padnavigator/padnavigator.cpp 7 - - We now create the animations that control the flip-effect when you press - the enter key. The main goal is to rotate the pad by 180 degrees or back. - - \list - \li \c smoothFlipRotation: Animates the main 180 degree rotation of the pad. - \li \c smoothFlipScale: Scales the pad out and then in again while the pad is rotating. - \li \c flipAnimation: A parallel animation group that ensures the above animations are run in parallel. - \endlist - - All animations are given a 500 millisecond duration and an - \l{QEasingCurve::InOutQuad}{InOutQuad} easing function. - - It's worth taking a close look at \c smoothFlipScale. This animation's - start and end values are both 1.0, but at animation step 0.5 the - animation's value is 0.7. This means that after 50% of the animation's - duration, or 250 milliseconds, the pad will be scaled down to 0.7x of its - original size, which gives a great visual effect while flipping. - - \snippet graphicsview/padnavigator/padnavigator.cpp 8 - - This section uses a trick to ensure that certain properties are assigned - precisely when the flip animation passes 50%, or 90 degrees, rotation. In - short, the pad's icons and selection item are all hidden, the pad's \c fill - property is enabled, and \c backItem is shown when flipping over. When - flipping back, the reverse properties are applied. - - The way this is achieved is by running a sequential animation in parallel - to the other animations. This sequence, dubbed \c setVariablesSequence, - starts with a 250 millisecond pause, and then executes several animations - with a duration of 0. Each animation will ensure that properties are set - immediate at this point. - - This approach can also be used to call functions or set any other - properties at a specific time while an animation is running. - - \snippet graphicsview/padnavigator/padnavigator.cpp 9 - - We will now create the state machine. The whole \c PadNavigator state - machinery is controlled by one single state machine that has a - straight-forward state structure. The state engine itself is created - as a child of the \c PadNavigator itself. We then create three top level - states: - - \list - \li \c splashState: The initial state where the splash item is visible. - \li \c frontState: The base state where the splash is gone and we can see - the front side of the pad, and navigate the selection item. - \li \c backState: The flipped state where the \c backItem is visible, and we - can interact with the QGraphicsProxyWidget-embedded form. - \endlist - - \snippet graphicsview/padnavigator/padnavigator.cpp 10 - - Each state assigns specific properties to objects on entry. Most - interesting perhaps is the assignment of the value 0.0 to the pad's \c - flipRotation angle property when in \c frontState, and 180.0 when in \c - backState. - - At the end of this section we register default animations with the state - engine; these animations will apply to their respective objects and - properties for any state transition. Otherwise it's common to assign - animations to specific transitions. - - Specifically, we use default animations to control the selection item's - movement and tilt rotations. The tilt rotations are set to 0 when the pad - is flipped, and restored back to their original values when flipped back. - - The \c splashState state is set as the initial state. This is required - before we start the state engine. We proceed with creating some - transitions. - - \snippet graphicsview/padnavigator/padnavigator.cpp 11 - - QEventTransition defines a very flexible transition type. You can use this - class to trigger a transition based on an object receiving an event of a - specific type. In this case, we would like to transition from \c - splashState into \c frontState if \c PadNavigator receives any key press - event (QEvent::KeyPress). - - We register the \c splashItem's animations to this transition to ensure they - are used to animate the item's movement and opacity. - - \snippet graphicsview/padnavigator/padnavigator.cpp 12 - - We use QKeyEventTransition to capture specific key events. In this case, we - detect that the user presses Qt::Key_Return or Qt::Key_Enter, and use this - to trigger transitions between \c frontState and backState. We register \c - flipAnimation, our complex parallel animation group, with these - transitions. - - We continue by defining the states for each of the icons in the grid. - - \snippet graphicsview/padnavigator/padnavigator.cpp 13 - - We will use state groups to control transitions between icons. Each icon - represents a \e substate of \c frontState. We will then define transitions - between the states by detecting key presses, using QKeyEventTransition. - - We start by creating all the substates, and at the same time we create a - temporary grid structure for the states to make it easier to find which - states represents icons that are up, down, left and to the right each - other. - - Once the first substate is known, we set this up as the initial substate of - \c frontState. We will use the (0, 0), or top-left, icon for the initial - substate. We initialze the selection item's position to be exactly where - the top-left icon is. - - \snippet graphicsview/padnavigator/padnavigator.cpp 14 - - We can now create four transitions for each icon. Each transition ensures - that we move to the state corresponding to which arrow key has been - pressed. It's clear from this techinique that we could design any other - specific transitions to and from each of the sub states depending on these - and other keys. - - \snippet graphicsview/padnavigator/padnavigator.cpp 15 - - Also, for each of the icons, we assign suitable values to the \c xRotation - and \c yRotation objects' "angle"-properties. If you recall, these - properties "tilt" the pad corresponding to which item is currently - selected. We ensure each icon is invisible when the pad is flipped, and - visible when the pad is not flipped. To ensure the visible property is - assigned at the right time, we add property-controlling animations to the - \c setVariableSequence animation defined earlier. - - \snippet graphicsview/padnavigator/padnavigator.cpp 16 - - We are now finished with all states, transitions, and animations. We now - create the scene that will contain all our items. The scene gets a defined - background pixmap, and we disable item indexing (as most items in this - scene are animated). We add our \c pad item to the scene, and use its - bounding rectangle to fixate the scene rectangle. This rectangle is used by - the view to find a suitable size for the application window. - - Then the scene is assigned to the view, or in our case, \c PadNavigator - itself. - - \snippet graphicsview/padnavigator/padnavigator.cpp 17 - - Now that the scene has received its final size, we can position the splash - item at the very top, find its fade-out position, and add it to the scene. - - \snippet graphicsview/padnavigator/padnavigator.cpp 18 - - The view toggles a few necessary properties: - - \list - \li It disables its scroll bars - this application has no use for scroll bars. - \li It assigns a minimum size. This is necessary to avoid numerical errors - in our fit-in-view \c resizeEvent() implementation. - \li It sets \l{QGraphicsView::FullViewportUpdate}{FullViewportUpdate}, to - ensure QGraphicsView doesn't spend time figuring out precisely what needs - to be redrawn. This application is very simple - if anything changes, - everything is updated. - \li It enables background caching - this makes no performance difference - with OpenGL, but without OpenGL it avoids unnecessary re-scaling of the - background pixmap. - \li It sets render hints that increase rendering quality. - \li If OpenGL is supported, a QOpenGLWidget viewport is assigned to the view. - \endlist - - Finally, we start the state engine. - - \snippet graphicsview/padnavigator/padnavigator.cpp 19 - - The \l{QGraphicsView::resizeEvent()}{resizeEvent()} implementation calls - the base implementation, and then calls QGraphicsView::fitInView() to scale - the scene so that it fits perfectly inside the view. - - By resizing the main application window, you can see this effect yourself. - The scene contents grow when you make the window larger, and shrink when - you make it smaller, while keeping the aspect ratio intact. - - \section1 The main() Function - - \snippet graphicsview/padnavigator/main.cpp 0 - - The \c main function creates the QApplication instance, uses - Q_INIT_RESOURCE to ensure our compiled-in resources aren't removed by the - linker, and then creates a 3x3 \c PadNavigator instance and shows it. - - Our flippable pad shows up with a suitable splash item once control returns - to the event loop. - - \section1 Performance Notes - - The example uses OpenGL if this is available, to achieve optimal - performance; otherwise perspective tranformations can be quite costly. - - Although this example does use QGraphicsProxyWidget to demonstrate - integration of Qt widget components integrated into Graphics View, using - QGraphicsProxyWidget comes with a performance penalty, and is therefore not - recommended for embedded development. - - This example uses extensive item caching to avoid rerendering of static - elements, at the expense of graphics memory. -*/ diff --git a/examples/widgets/doc/src/pingpong.qdoc b/examples/widgets/doc/src/pingpong.qdoc deleted file mode 100644 index 9545058500..0000000000 --- a/examples/widgets/doc/src/pingpong.qdoc +++ /dev/null @@ -1,93 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2016 The Qt Company Ltd. -** Contact: https://www.qt.io/licensing/ -** -** This file is part of the documentation of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:FDL$ -** Commercial License Usage -** Licensees holding valid commercial Qt licenses may use this file in -** accordance with the commercial license agreement provided with the -** Software or, alternatively, in accordance with the terms contained in -** a written agreement between you and The Qt Company.

Do you see the - \c{@} in the screenshot? That's you, the rogue. The \c{#} - characters are walls, and the dots represent floor. In a real - game, other ASCII characters would represent all kinds of objects - and creatures, for instance, ancient dragons (\c{D}s) or food - rations (\c{%}s). But let's not get carried away. In this game, - the rogue is simply running around in an empty room. - - The rogue is moved with the keypad (2, 4, 8, 6). That aside, we - have implemented a \c quit command that triggers if the player - types \c {q}. The player is then asked if he/she really wants to - quit. - - Most games have commands that need more than one key press (we - think of consecutive presses, i.e., not of several keys being - pressed at the same time). In this game, only the \c quit command - falls under this category, but for the sake of argument, let's - imagine a fully-fledged game with a rich set of commands. If we - were to implement these by catching key events in - \l{QWidget::}{keyPressEvent()}, we would have to keep a lot of - class member variables to track the sequence of keys already typed - (or find some other way of deducing the current state of a - command). This can easily lead to spaghetti, which is--as we all - well know, I'm sure--unpleasant. With a state machine, on the - other hand, separate states can wait for a single key press, and - that makes our lives a lot simpler. - - The example consists of two classes: - - \list - \li \c Window draws the text display of the game and sets - up the state machine. The window also has a status bar - above the area in which the rouge moves. - \li \c MovementTransition is a transition that carries out - a single move of the rogue. - \endlist - - Before we embark on a code walkthrough, it is necessary to take a - closer look at the design of the machine. Here is a state chart - that shows what we want to achieve: - - \image rogue-statechart.png - - The input state waits for a key press to start a new command. - When receiving a key it recognizes, it transitions to one of the - two commands of the game; though, as we will see, movement is - handled by the transition itself. The quit state waits for the - player to answer yes or no (by typing \c y or \c n) when asked - whether he/she really wants to quit the game. - - The chart demonstrates how we use one state to wait for a single - key press. The press received may trigger one of the transitions - connected to the state. - - \section1 Window Class Definition - - The \c Window class is a widget that draws the text display of the - game. It also sets up the state machine, i.e., creates and - connects the states in the machine. It is the key events from this - widget that are used by the machine. - - \snippet statemachine/rogue/window.h 0 - - \c Direction specifies the direction in which the rogue is to - move. We use this in \c movePlayer(), which moves the rogue and - repaints the window. The game has a status line above the area in - which the rogue moves. The \c status property contains the text of - this line. We use a property because the QState class allows - setting any Qt \l{Qt's Property System}{property} when entered. - More on this later. - - \snippet statemachine/rogue/window.h 1 - - The \c map is an array with the characters that are currently - displayed. We set up the array in \c setupMap(), and update it - when the rogue is moved. \c pX and \c pY is the current position - of the rogue. \c WIDTH and \c HEIGHT are macros specifying the - dimensions of the map. - - The \c paintEvent() function is left out of this walkthrough. We - also do not discuss other code that does not concern the state - machine (the \c setupMap(), \c status(), \c setStatus(), \c - movePlayer(), and \c sizeHint() functions). If you wish to take a - look at the code, click on the link for the \c window.cpp file at - the top of this page. - - \section1 Window Class Implementation - - Here is the constructor of \c Window: - - \snippet statemachine/rogue/window.cpp 0 - \dots - \snippet statemachine/rogue/window.cpp 1 - - The player starts off at position (5, 5). We then set up the map - and statemachine. Let's proceed with the \c buildMachine() - function: - - \snippet statemachine/rogue/window.cpp 2 - - We enter \c inputState when the machine is started and from the \c - quitState if the user wants to continue playing. We then set the - status to a helpful reminder of how to play the game. - - First, the \c Movement transition is added to the input state. - This will enable the rogue to be moved with the keypad. Notice - that we don't set a target state for the movement transition. This - will cause the transition to be triggered (and the - \l{QAbstractTransition::}{onTransition()} function to be invoked), - but the machine will not leave the \c inputState. If we had set \c - inputState as the target state, we would first have left and then - entered the \c inputState again. - - \snippet statemachine/rogue/window.cpp 3 - - When we enter \c quitState, we update the status bar of the - window. - - \c QKeyEventTransition is a utility class that removes the hassle - of implementing transitions for \l{QKeyEvent}s. We simply need to - specify the key on which the transition should trigger and the - target state of the transition. - - \snippet statemachine/rogue/window.cpp 4 - - The transition from \c inputState allows triggering the quit state - when the player types \c {q}. - - \snippet statemachine/rogue/window.cpp 5 - - The machine is set up, so it's time to start it. - - \section1 The MovementTransition Class - - \c MovementTransition is triggered when the player request the - rogue to be moved (by typing 2, 4, 6, or 8) when the machine is in - the \c inputState. - - \snippet statemachine/rogue/movementtransition.h 0 - - In the constructor, we tell QEventTransition to only send - \l{QEvent::}{KeyPress} events to the - \l{QAbstractTransition::}{eventTest()} function: - - \snippet statemachine/rogue/movementtransition.h 1 - - The KeyPress events come wrapped in \l{QStateMachine::WrappedEvent}s. \c event - must be confirmed to be a wrapped event because Qt uses other - events internally. After that, it is simply a matter of checking - which key has been pressed. - - Let's move on to the \c onTransition() function: - - \snippet statemachine/rogue/movementtransition.h 2 - - When \c onTransition() is invoked, we know that we have a - \l{QEvent::}{KeyPress} event with 2, 4, 6, or 8, and can ask \c - Window to move the player. - - \section1 The Roguelike Tradition - - You might have been wondering why the game features a rogue. Well, - these kinds of text based dungeon exploration games date back to a - game called, yes, "Rogue". Although outflanked by the technology - of modern 3D computer games, roguelikes have a solid community of - hard-core, devoted followers. - - Playing these games can be surprisingly addictive (despite the - lack of graphics). Angband, the perhaps most well-known rougelike, - is found here: \l{http://rephial.org/}. -*/ - diff --git a/examples/widgets/doc/src/states.qdoc b/examples/widgets/doc/src/states.qdoc deleted file mode 100644 index 1ae379f918..0000000000 --- a/examples/widgets/doc/src/states.qdoc +++ /dev/null @@ -1,36 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2016 The Qt Company Ltd. -** Contact: https://www.qt.io/licensing/ -** -** This file is part of the documentation of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:FDL$ -** Commercial License Usage -** Licensees holding valid commercial Qt licenses may use this file in -** accordance with the commercial license agreement provided with the -** Software or, alternatively, in accordance with the terms contained in -** a written agreement between you and The Qt Company.

The stickman can be either "alive" or "dead", and when in the - "alive" state, he can be performing different actions defined by key frame animations. - - Animations are implemented as composite states. Each child state of the animation state - represents a frame in the animation by setting the position of each joint in the stickman's - skeleton to the positions defined for the particular frame. The frames are then bound together - with animated transitions that trigger on the source state's propertiesAssigned() signal. Thus, - the machine will enter the state representing the next frame in the animation immediately after - it has finished animating into the previous frame. - - \image stickman-example1.png - - The states for an animation is constructed by reading a custom animation file format and - creating states that assign values to the "position" properties of each of the nodes in the - skeleton graph. - - \snippet animation/stickman/lifecycle.cpp 1 - - The states are then bound together with signal transitions that listen to the - propertiesAssigned() signal. - - \snippet animation/stickman/lifecycle.cpp 2 - - The last frame state is given a transition to the first one, so that the animation will loop - until it is interrupted when a transition out from the animation state is taken.

Transitions go from the parent - state to the child state to ensure that each of the child states inherit them. - - \image stickman-example2.png - - This saves us the effort of connect every state to every state with identical transitions.

When either state is - entered, the text of the button will be set accordingly. - - \snippet statemachine/twowaybutton/main.cpp 2 - - When the state machine is in the \c off state and the button is clicked, - it will transition to the \c on state; when the state machine is in the \c - on state and the button is clicked, it will transition to the \c off - state. - - \snippet statemachine/twowaybutton/main.cpp 3 - - The states are added to the state machine; they become top-level (sibling) - states. - - \snippet statemachine/twowaybutton/main.cpp 4 - - The initial state is \c off; this is the state the state machine will - immediately transition to once the state machine is started. - - \snippet statemachine/twowaybutton/main.cpp 5 - - Finally, the button is resized and made visible, and the application event - loop is entered. -

The concepts and notation are based on those from Harel's - \l{http://www.wisdom.weizmann.ac.il/~dharel/SCANNED.PAPERS/Statecharts.pdf}{Statecharts: A visual formalism for complex systems}, which - is also the basis of UML state diagrams. The semantics of state machine - execution are based on \l{State Chart XML: State Machine Notation for - Control Abstraction}{State Chart XML (SCXML)}. - - Statecharts provide a graphical way of modeling how a system reacts to - stimuli. This is done by defining the possible \e states that the system can - be in, and how the system can move from one state to another (\e transitions - between states). A key characteristic of event-driven systems (such as Qt - applications) is that behavior often depends not only on the last or current - event, but also the events that preceded it. With statecharts, this - information is easy to express. - - The State Machine framework provides an API and execution model that can be - used to effectively embed the elements and semantics of statecharts in Qt - applications. The framework integrates tightly with Qt's meta-object system; - for example, transitions between states can be triggered by signals, and - states can be configured to set properties and invoke methods on {QObject}s. - Qt's event system is used to drive the state machines. - - The state graph in the State Machine framework is hierarchical. States can be nested inside of - other states, and the current configuration of the state machine consists of the set of states - which are currently active. All the states in a valid configuration of the state machine will - have a common ancestor. - - \sa {The Declarative State Machine Framework} - - \section1 Classes in the State Machine Framework - - These classes are provided by qt for creating event-driven state machines. - - \annotatedlist statemachine - - \section1 A Simple State Machine - - To demonstrate the core functionality of the State Machine API, let's look - at a small example: A state machine with three states, \c s1, \c s2 and \c - s3. The state machine is controlled by a single QPushButton; when the button - is clicked, the machine transitions to another state. Initially, the state - machine is in state \c s1. The statechart for this machine is as follows: - - \image statemachine-button.png - \omit - \caption This is a caption - \endomit - - The following snippet shows the code needed to create such a state machine. - First, we create the state machine and states: - - \snippet statemachine/main.cpp 0 - - Then, we create the transitions by using the QState::addTransition() - function: - - \snippet statemachine/main.cpp 1 - - Next, we add the states to the machine and set the machine's initial state: - - \snippet statemachine/main.cpp 2 - - Finally, we start the state machine: - - \snippet statemachine/main.cpp 3 - - The state machine executes asynchronously, i.e. it becomes part of your - application's event loop. - - \section1 Doing Useful Work on State Entry and Exit - - The above state machine merely transitions from one state to another, it - doesn't perform any operations. The QState::assignProperty() function can be - used to have a state set a property of a QObject when the state is - entered. In the following snippet, the value that should be assigned to a - QLabel's text property is specified for each state: - - \snippet statemachine/main.cpp 4 - - When any of the states is entered, the label's text will be changed - accordingly. - - The QState::entered() signal is emitted when the state is entered, and the - QState::exited() signal is emitted when the state is exited. In the - following snippet, the button's \l {QPushButton::}{showMaximized()} slot - will be called when state \c s3 is entered, and the button's \l {QPushButton::}{showMinimized()} - slot will be called when \c s3 is exited: - - \snippet statemachine/main.cpp 5 - - Custom states can reimplement QAbstractState::onEntry() and - QAbstractState::onExit(). - - \section1 State Machines That Finish - - The state machine defined in the previous section never finishes. In order - for a state machine to be able to finish, it needs to have a top-level \e - final state (QFinalState object). When the state machine enters a top-level - final state, the machine will emit the QStateMachine::finished() signal and - halt. - - All you need to do to introduce a final state in the graph is create a - QFinalState object and use it as the target of one or more transitions. - - \section1 Sharing Transitions By Grouping States - - Assume we wanted the user to be able to quit the application at any time by - clicking a Quit button. In order to achieve this, we need to create a final - state and make it the target of a transition associated with the Quit - button's \l{QPushButton::}{clicked()} signal. We could add a transition from each of \c s1, \c - s2 and \c s3; however, this seems redundant, and one would also have to - remember to add such a transition from every new state that is added in the - future. - - We can achieve the same behavior (namely that clicking the Quit button quits - the state machine, regardless of which state the state machine is in) by - grouping states \c s1, \c s2 and \c s3. This is done by creating a new - top-level state and making the three original states children of the new - state. The following diagram shows the new state machine. - - \image statemachine-button-nested.png - \omit - \caption This is a caption - \endomit - - The three original states have been renamed \c s11, \c s12 and \c s13 to - reflect that they are now children of the new top-level state, \c s1. Child - states implicitly inherit the transitions of their parent state. This means - it is now sufficient to add a single transition from \c s1 to the final - state \c s2. New states added to \c s1 will also automatically inherit this - transition. - - All that's needed to group states is to specify the proper parent when the - state is created. You also need to specify which of the child states is the - initial one (i.e. which child state the state machine should enter when the - parent state is the target of a transition). - - \snippet statemachine/main2.cpp 0 - - \snippet statemachine/main2.cpp 1 - - In this case we want the application to quit when the state machine is - finished, so the machine's \l {QStateMachine::}{finished()} signal is connected to the - application's \l {QCoreApplication::}{quit()} slot. - - A child state can override an inherited transition. For example, the - following code adds a transition that effectively causes the Quit button to - be ignored when the state machine is in state \c s12. - - \snippet statemachine/main2.cpp 2 - - A transition can have any state as its target, i.e. the target state does - not have to be on the same level in the state hierarchy as the source state. - - \section1 Using History States to Save and Restore the Current State - - Imagine that we wanted to add an "interrupt" mechanism to the example - discussed in the previous section; the user should be able to click a button - to have the state machine perform some non-related task, after which the - state machine should resume whatever it was doing before (i.e. return to the - old state, which is one of \c s11, \c s12 and \c s13 in this case). - - Such behavior can easily be modeled using \e{history states}. A history - state (QHistoryState object) is a pseudo-state that represents the child - state that the parent state was in the last time the parent state was - exited. - - A history state is created as a child of the state for which we wish to - record the current child state; when the state machine detects the presence - of such a state at runtime, it automatically records the current (real) - child state when the parent state is exited. A transition to the history - state is in fact a transition to the child state that the state machine had - previously saved; the state machine automatically "forwards" the transition - to the real child state. - - The following diagram shows the state machine after the interrupt mechanism - has been added. - - \image statemachine-button-history.png - \omit - \caption This is a caption - \endomit - - The following code shows how it can be implemented; in this example we - simply display a message box when \c s3 is entered, then immediately return - to the previous child state of \c s1 via the history state. - - \snippet statemachine/main2.cpp 3 - - \section1 Using Parallel States to Avoid a Combinatorial Explosion of States - - Assume that you wanted to model a set of mutually exclusive properties of a - car in a single state machine. Let's say the properties we are interested in - are Clean vs Dirty, and Moving vs Not moving. It would take four mutually - exclusive states and eight transitions to be able to represent and freely - move between all possible combinations. - - \image statemachine-nonparallel.png - \omit - \caption This is a caption - \endomit - - If we added a third property (say, Red vs Blue), the total number of states - would double, to eight; and if we added a fourth property (say, Enclosed vs - Convertible), the total number of states would double again, to 16. - - Using parallel states, the total number of states and transitions grows - linearly as we add more properties, instead of exponentially. Furthermore, - states can be added to or removed from the parallel state without affecting - any of their sibling states. - - \image statemachine-parallel.png - \omit - \caption This is a caption - \endomit - - To create a parallel state group, pass QState::ParallelStates to the QState - constructor. - - \snippet statemachine/main3.cpp 0 - - When a parallel state group is entered, all its child states will be - simultaneously entered. Transitions within the individual child states - operate normally. However, any of the child states may take a transition which exits the parent - state. When this happens, the parent state and all of its child states are exited. - - The parallelism in the State Machine framework follows an interleaved semantics. All parallel - operations will be executed in a single, atomic step of the event processing, so no event can - interrupt the parallel operations. However, events will still be processed sequentially, since - the machine itself is single threaded. As an example: Consider the situation where there are two - transitions that exit the same parallel state group, and their conditions become true - simultaneously. In this case, the event that is processed last of the two will not have any - effect, since the first event will already have caused the machine to exit from the parallel - state. - - \section1 Detecting that a Composite State has Finished - - A child state can be final (a QFinalState object); when a final child state - is entered, the parent state emits the QState::finished() signal. The - following diagram shows a composite state \c s1 which does some processing - before entering a final state: - - \image statemachine-finished.png - \omit - \caption This is a caption - \endomit - - When \c s1 's final state is entered, \c s1 will automatically emit - \l {QState::}{finished()}. We use a signal transition to cause this event to trigger a - state change: - - \snippet statemachine/main3.cpp 1 - - Using final states in composite states is useful when you want to hide the - internal details of a composite state; i.e. the only thing the outside world - should be able to do is enter the state, and get a notification when the - state has completed its work. This is a very powerful abstraction and - encapsulation mechanism when building complex (deeply nested) state - machines. (In the above example, you could of course create a transition - directly from \c s1 's \c done state rather than relying on \c s1 's - \l {QState::}{finished()} signal, but with the consequence that implementation details of - \c s1 are exposed and depended on). - - For parallel state groups, the QState::finished() signal is emitted when \e - all the child states have entered final states. - - \section1 Targetless Transitions - - A transition need not have a target state. A transition without a target can - be triggered the same way as any other transition; the difference is that - when a targetless transition is triggered, it doesn't cause any state - changes. This allows you to react to a signal or event when your machine is - in a certain state, without having to leave that state. Example: - - \code - QStateMachine machine; - QState *s1 = new QState(&machine); - - QPushButton button; - QSignalTransition *trans = new QSignalTransition(&button, &QPushButton::clicked); - s1->addTransition(trans); - - QMessageBox msgBox; - msgBox.setText("The button was clicked; carry on."); - QObject::connect(trans, QSignalTransition::triggered, &msgBox, &QMessageBox::exec); - - machine.setInitialState(s1); - \endcode - - The message box will be displayed each time the button is clicked, but the - state machine will remain in its current state (s1). If the target state - were explicitly set to s1, however, s1 would be exited and re-entered each - time (e.g. the QAbstractState::entered() and QAbstractState::exited() - signals would be emitted). - - \section1 Events, Transitions and Guards - - A QStateMachine runs its own event loop. For signal transitions - (QSignalTransition objects), QStateMachine automatically posts a - QStateMachine::SignalEvent to itself when it intercepts the corresponding - signal; similarly, for QObject event transitions (QEventTransition objects) - a QStateMachine::WrappedEvent is posted. - - You can post your own events to the state machine using - QStateMachine::postEvent(). - - When posting a custom event to the state machine, you typically also have - one or more custom transitions that can be triggered from events of that - type. To create such a transition, you subclass QAbstractTransition and - reimplement QAbstractTransition::eventTest(), where you check if an event - matches your event type (and optionally other criteria, e.g. attributes of - the event object). - - Here we define our own custom event type, \c StringEvent, for posting - strings to the state machine: - - \snippet statemachine/main4.cpp 0 - - Next, we define a transition that only triggers when the event's string - matches a particular string (a \e guarded transition): - - \snippet statemachine/main4.cpp 1 - - In the \l {QAbstractTransition::}{eventTest()} reimplementation, we first check if the event type is the - desired one; if so, we cast the event to a \c StringEvent and perform the - string comparison. - - The following is a statechart that uses the custom event and transition: - - \image statemachine-customevents.png - \omit - \caption This is a caption - \endomit - - Here's what the implementation of the statechart looks like: - - \snippet statemachine/main4.cpp 2 - - Once the machine is started, we can post events to it. - - \snippet statemachine/main4.cpp 3 - - An event that is not handled by any relevant transition will be silently - consumed by the state machine. It can be useful to group states and provide - a default handling of such events; for example, as illustrated in the - following statechart: - - \image statemachine-customevents2.png - \omit - \caption This is a caption - \endomit - - For deeply nested statecharts, you can add such "fallback" transitions at - the level of granularity that's most appropriate. - - \section1 Using Restore Policy To Automatically Restore Properties - - In some state machines it can be useful to focus the attention on assigning properties in states, - not on restoring them when the state is no longer active. If you know that a property should - always be restored to its initial value when the machine enters a state that does not explicitly - give the property a value, you can set the global restore policy to - QStateMachine::RestoreProperties. - - \code - QStateMachine machine; - machine.setGlobalRestorePolicy(QStateMachine::RestoreProperties); - \endcode - - When this restore policy is set, the machine will automatically restore all properties. If it - enters a state where a given property is not set, it will first search the hierarchy of ancestors - to see if the property is defined there. If it is, the property will be restored to the value - defined by the closest ancestor. If not, it will be restored to its initial value (i.e. the - value of the property before any property assignments in states were executed.) - - Take the following code: - - \snippet statemachine/main5.cpp 0 - - Lets say the property \c fooBar is 0.0 when the machine starts. When the machine is in state - \c s1, the property will be 1.0, since the state explicitly assigns this value to it. When the - machine is in state \c s2, no value is explicitly defined for the property, so it will implicitly - be restored to 0.0. - - If we are using nested states, the parent defines a value for the property which is inherited by - all descendants that do not explicitly assign a value to the property. - - \snippet statemachine/main5.cpp 2 - - Here \c s1 has two children: \c s2 and \c s3. When \c s2 is entered, the property \c fooBar - will have the value 2.0, since this is explicitly defined for the state. When the machine is in - state \c s3, no value is defined for the state, but \c s1 defines the property to be 1.0, so this - is the value that will be assigned to \c fooBar. - - \section1 Animating Property Assignments - - The State Machine API connects with the Animation API in Qt to allow automatically animating - properties as they are assigned in states. - - Say we have the following code: - - \snippet statemachine/main5.cpp 3 - - Here we define two states of a user interface. In \c s1 the \c button is small, and in \c s2 - it is bigger. If we click the button to transition from \c s1 to \c s2, the geometry of the button - will be set immediately when a given state has been entered. If we want the transition to be - smooth, however, all we need to do is make a QPropertyAnimation and add this to the transition - object. - - \snippet statemachine/main5.cpp 4 - - Adding an animation for the property in question means that the property assignment will no - longer take immediate effect when the state has been entered. Instead, the animation will start - playing when the state has been entered and smoothly animate the property assignment. Since we - do not set the start value or end value of the animation, these will be set implicitly. The - start value of the animation will be the property's current value when the animation starts, and - the end value will be set based on the property assignments defined for the state. - - If the global restore policy of the state machine is set to QStateMachine::RestoreProperties, - it is possible to also add animations for the property restorations. - - \section1 Detecting That All Properties Have Been Set In A State - - When animations are used to assign properties, a state no longer defines the exact values that a - property will have when the machine is in the given state. While the animation is running, the - property can potentially have any value, depending on the animation. - - In some cases, it can be useful to be able to detect when the property has actually been assigned - the value defined by a state. - - Say we have the following code: - - \snippet statemachine/main5.cpp 5 - - When \c button is clicked, the machine will transition into state \c s2, which will set the - geometry of the button, and then pop up a message box to alert the user that the geometry has - been changed. - - In the normal case, where animations are not used, this will operate as expected. However, if - an animation for the \c geometry of \c button is set on the transition between \c s1 and \c s2, - the animation will be started when \c s2 is entered, but the \c geometry property will not - actually reach its defined value before the animation is finished running. In this case, the - message box will pop up before the geometry of the button has actually been set. - - To ensure that the message box does not pop up until the geometry actually reaches its final - value, we can use the state's \l {QState::}{propertiesAssigned()} signal. The \l {QState::}{propertiesAssigned()} signal will be - emitted when the property is assigned its final value, whether this is done immediately or - after the animation has finished playing. - - \snippet statemachine/main5.cpp 6 - - In this example, when \c button is clicked, the machine will enter \c s2. It will remain in state - \c s2 until the \c geometry property has been set to \c QRect(0, 0, 50, 50). Then it will - transition into \c s3. When \c s3 is entered, the message box will pop up. If the transition into - \c s2 has an animation for the \c geometry property, then the machine will stay in \c s2 until the - animation has finished playing. If there is no such animation, it will simply set the property and - immediately enter state \c s3. - - Either way, when the machine is in state \c s3, you are guaranteed that the property \c geometry - has been assigned the defined value. - - If the global restore policy is set to QStateMachine::RestoreProperties, the state will not emit - the \l {QState::}{propertiesAssigned()} signal until these have been executed as well. - - \section1 What Happens If A State Is Exited Before The Animation Has Finished - - If a state has property assignments, and the transition into the state has animations for the - properties, the state can potentially be exited before the properties have been assigned to the - values defines by the state. This is true in particular when there are transitions out from the - state that do not depend on the \l {QState::}{propertiesAssigned()} signal, as described in the previous section. - - The State Machine API guarantees that a property assigned by the state machine either: - \list - \li Has a value explicitly assigned to the property. - \li Is currently being animated into a value explicitly assigned to the property. - \endlist - - When a state is exited prior to the animation finishing, the behavior of the state machine depends - on the target state of the transition. If the target state explicitly assigns a value to the - property, no additional action will be taken. The property will be assigned the value defined by - the target state. - - If the target state does not assign any value to the property, there are two - options: By default, the property will be assigned the value defined by the state it is leaving - (the value it would have been assigned if the animation had been permitted to finish playing). If - a global restore policy is set, however, this will take precedence, and the property will be - restored as usual. - - \section1 Default Animations - - As described earlier, you can add animations to transitions to make sure property assignments - in the target state are animated. If you want a specific animation to be used for a given property - regardless of which transition is taken, you can add it as a default animation to the state - machine. This is in particular useful when the properties assigned (or restored) by specific - states is not known when the machine is constructed. - - \code - QState *s1 = new QState(); - QState *s2 = new QState(); - - s2->assignProperty(object, "fooBar", 2.0); - s1->addTransition(s2); - - QStateMachine machine; - machine.setInitialState(s1); - machine.addDefaultAnimation(new QPropertyAnimation(object, "fooBar")); - \endcode - - When the machine is in state \c s2, the machine will play the default animation for the - property \c fooBar since this property is assigned by \c s2. - - Note that animations explicitly set on transitions will take precedence over any default - animation for the given property. - - \section1 Nesting State Machines - - QStateMachine is a subclass of QState. This allows for a state machine to be a child state of - another machine. QStateMachine reimplements QState::onEntry() and calls QStateMachine::start(), - so that when the child state machine is entered, it will automatically start running. - - The parent state machine treats the child machine as an \e atomic state in the state machine - algorithm. The child state machine is self-contained; it maintains its own event queue and - configuration. In particular, note that the \l{QStateMachine::}{configuration()} - of the child machine is not part of the parent machine's configuration (only the child machine - itself is). - - States of the child state machine cannot be specified as targets of transitions in the parent - state machine; only the child state machine itself can. Conversely, states of the parent state - machine cannot be specified as targets of transitions in the child state machine. The child - state machine's \l{QState::}{finished}() signal can be used to trigger a transition - in the parent machine. -*/ diff --git a/src/corelib/kernel/qcoreapplication.cpp b/src/corelib/kernel/qcoreapplication.cpp index 303190ae69..ab1d500087 100644 --- a/src/corelib/kernel/qcoreapplication.cpp +++ b/src/corelib/kernel/qcoreapplication.cpp @@ -2207,6 +2207,22 @@ void QCoreApplicationPrivate::setApplicationFilePath(const QString &path) QCoreApplicationPrivate::cachedApplicationFilePath = new QString(path); } +#ifndef QT_NO_QOBJECT +QEvent *QCoreApplicationPrivate::cloneEvent(QEvent *e) +{ + switch (e->type()) { + case QEvent::None: + return new QEvent(*e); + case QEvent::Timer: + return new QTimerEvent(*static_cast<QTimerEvent*>(e)); + default: + Q_ASSERT_X(false, "cloneEvent()", "not implemented"); + break; + } + return nullptr; +} +#endif + /*!

Once a state graph has been - built, the state machine can execute it. QStateMachine's - execution algorithm is based on the \l{http://www.w3.org/TR/scxml/}{State Chart XML (SCXML)} - algorithm. The framework's \l{The State Machine - Framework}{overview} gives several state graphs and the code to - build them. - - Use the addState() function to add a top-level state to the state machine. - States are removed with the removeState() function. Removing states while - the machine is running is discouraged. - - Before the machine can be started, the \l{initialState}{initial - state} must be set. The initial state is the state that the - machine enters when started. You can then start() the state - machine. The started() signal is emitted when the initial state is - entered. - - The machine is event driven and keeps its own event loop. Events - are posted to the machine through postEvent(). Note that this - means that it executes asynchronously, and that it will not - progress without a running event loop. You will normally not have - to post events to the machine directly as Qt's transitions, e.g., - QEventTransition and its subclasses, handle this. But for custom - transitions triggered by events, postEvent() is useful. - - The state machine processes events and takes transitions until a - top-level final state is entered; the state machine then emits the - finished() signal. You can also stop() the state machine - explicitly. The stopped() signal is emitted in this case. - - The following snippet shows a state machine that will finish when a button - is clicked: - - \snippet code/src_corelib_statemachine_qstatemachine.cpp simple state machine - - This code example uses QState, which inherits QAbstractState. The - QState class provides a state that you can use to set properties - and invoke methods on \l{QObject}s when the state is entered or - exited. It also contains convenience functions for adding - transitions, e.g., \l{QSignalTransition}s as in this example. See - the QState class description for further details. - - If an error is encountered, the machine will look for an - \l{errorState}{error state}, and if one is available, it will - enter this state. The types of errors possible are described by the - \l{QStateMachine::}{Error} enum. After the error state is entered, - the type of the error can be retrieved with error(). The execution - of the state graph will not stop when the error state is entered. If - no error state applies to the erroneous state, the machine will stop - executing and an error message will be printed to the console. - - \note Important: setting the \l{ChildMode} of a state machine to parallel (\l{ParallelStates}) - results in an invalid state machine. It can only be set to (or kept as) - \l{ExclusiveStates}. - - \sa QAbstractState, QAbstractTransition, QState, {The State Machine Framework} -*/ - -/*! - \property QStateMachine::errorString - - \brief the error string of this state machine -*/ - -/*! - \property QStateMachine::globalRestorePolicy - - \brief the restore policy for states of this state machine. - - The default value of this property is - QState::DontRestoreProperties. -*/ - -/*! - \property QStateMachine::running - \since 5.4 - - \brief the running state of this state machine - - \sa start(), stop(), started(), stopped(), runningChanged() -*/ - -#if QT_CONFIG(animation) -/*! - \property QStateMachine::animated - - \brief whether animations are enabled - - The default value of this property is \c true. - - \sa QAbstractTransition::addAnimation() -*/ -#endif - -// #define QSTATEMACHINE_DEBUG -// #define QSTATEMACHINE_RESTORE_PROPERTIES_DEBUG - -struct CalculationCache { - struct TransitionInfo { - QList<QAbstractState*> effectiveTargetStates; - QSet<QAbstractState*> exitSet; - QAbstractState *transitionDomain; - - bool effectiveTargetStatesIsKnown: 1; - bool exitSetIsKnown : 1; - bool transitionDomainIsKnown : 1; - - TransitionInfo() - : transitionDomain(nullptr) - , effectiveTargetStatesIsKnown(false) - , exitSetIsKnown(false) - , transitionDomainIsKnown(false) - {} - }; - - typedef QHash<QAbstractTransition *, TransitionInfo> TransitionInfoCache; - TransitionInfoCache cache; - - bool effectiveTargetStates(QAbstractTransition *t, QList<QAbstractState *> *targets) const - { - Q_ASSERT(targets); - - TransitionInfoCache::const_iterator cacheIt = cache.find(t); - if (cacheIt == cache.end() || !cacheIt->effectiveTargetStatesIsKnown) - return false; - - *targets = cacheIt->effectiveTargetStates; - return true; - } - - void insert(QAbstractTransition *t, const QList<QAbstractState *> &targets) - { - TransitionInfoCache::iterator cacheIt = cache.find(t); - TransitionInfo &ti = cacheIt == cache.end() - ? *cache.insert(t, TransitionInfo()) - : *cacheIt; - - Q_ASSERT(!ti.effectiveTargetStatesIsKnown); - ti.effectiveTargetStates = targets; - ti.effectiveTargetStatesIsKnown = true; - } - - bool exitSet(QAbstractTransition *t, QSet<QAbstractState *> *exits) const - { - Q_ASSERT(exits); - - TransitionInfoCache::const_iterator cacheIt = cache.find(t); - if (cacheIt == cache.end() || !cacheIt->exitSetIsKnown) - return false; - - *exits = cacheIt->exitSet; - return true; - } - - void insert(QAbstractTransition *t, const QSet<QAbstractState *> &exits) - { - TransitionInfoCache::iterator cacheIt = cache.find(t); - TransitionInfo &ti = cacheIt == cache.end() - ? *cache.insert(t, TransitionInfo()) - : *cacheIt; - - Q_ASSERT(!ti.exitSetIsKnown); - ti.exitSet = exits; - ti.exitSetIsKnown = true; - } - - bool transitionDomain(QAbstractTransition *t, QAbstractState **domain) const - { - Q_ASSERT(domain); - - TransitionInfoCache::const_iterator cacheIt = cache.find(t); - if (cacheIt == cache.end() || !cacheIt->transitionDomainIsKnown) - return false; - - *domain = cacheIt->transitionDomain; - return true; - } - - void insert(QAbstractTransition *t, QAbstractState *domain) - { - TransitionInfoCache::iterator cacheIt = cache.find(t); - TransitionInfo &ti = cacheIt == cache.end() - ? *cache.insert(t, TransitionInfo()) - : *cacheIt; - - Q_ASSERT(!ti.transitionDomainIsKnown); - ti.transitionDomain = domain; - ti.transitionDomainIsKnown = true; - } -}; - -/* The function as described in http://www.w3.org/TR/2014/WD-scxml-20140529/ : - -function isDescendant(state1, state2) - -Returns 'true' if state1 is a descendant of state2 (a child, or a child of a child, or a child of a -child of a child, etc.) Otherwise returns 'false'. -*/ -static inline bool isDescendant(const QAbstractState *state1, const QAbstractState *state2) -{ - Q_ASSERT(state1 != nullptr); - - for (QAbstractState *it = state1->parentState(); it != nullptr; it = it->parentState()) { - if (it == state2) - return true; - } - - return false; -} - -static bool containsDecendantOf(const QSet<QAbstractState *> &states, const QAbstractState *node) -{ - for (QAbstractState *s : states) - if (isDescendant(s, node)) - return true; - - return false; -} - -static int descendantDepth(const QAbstractState *state, const QAbstractState *ancestor) -{ - int depth = 0; - for (const QAbstractState *it = state; it != nullptr; it = it->parentState()) { - if (it == ancestor) - break; - ++depth; - } - return depth; -} - -/* The function as described in http://www.w3.org/TR/2014/WD-scxml-20140529/ : - -function getProperAncestors(state1, state2) - -If state2 is null, returns the set of all ancestors of state1 in ancestry order (state1's parent -followed by the parent's parent, etc. up to an including the <scxml> element).
