The application logic is implemented in - JavaScript and the appearance is implemented in QML. - - \include examples-run.qdocinc - - \section1 Displaying Custom Components - - In the Calqlatr application, we use the following custom types that are - each defined in a separate .qml file: - - \list - \li Button.qml - \li Display.qml - \li NumberPad.qml - \endlist - - To use the custom types, we add an import statement to the main QML file, - calqlatr.qml that imports the folder called \c content where the types are - located: - - \code - import "content" - \endcode - - We can then display custom components by adding the component types to - any QML file. For example, we use the NumberPad type in calqlatr.qml to - create the number pad of the calculator. We place the type inside an - \l{Item} QML type, which is the base type for all visual items in Qt Quick: - - \quotefromfile demos/calqlatr/calqlatr.qml - \skipto Item - \printuntil } - \printuntil } - - Further, we use the Button type in the \c NumberPad type to create the - calculator buttons. Button.qml specifies the basic properties for a - button that we can modify for each button instance in NumberPad.qml. For the - digit and separator buttons, we additionally specify the text property using - the property alias \c text that we define in Button.qml. - - For the operator buttons, we also specify another color (green) using the - property alias \c color and set the operator property to \c true. We use - the operator property in functions that perform the calculations. - - We place the buttons inside a \l{Grid} QML type to position them in a grid: - - \quotefromfile demos/calqlatr/content/NumberPad.qml - \skipto Grid - \printuntil /^\}/ - - Some of the buttons also have a \c dimmable property set, meaning that they - can be visually disabled (dimmed) whenever the calculator engine does not - accept input from that button. As an example, the button for square root - operator is dimmed for negative values. - - \section1 Animating Components - - We use the Display type to display calculations. In Display.qml, we use - images to make the display component look like a slip of paper that contains - a grip. Users can drag the grip to move the display from left to right. - - When users release the grip, the AnimationController QML type that we define - in the calqlatr.qml file finishes running the controlled animation in either - a forwards or a backwards direction. To run the animation, we call either - completeToEnd() or completeToBeginning(), depending on the direction. We do - this in the MouseArea's \c onReleased signal handler, where \c controller - is the id of our AnimationController: - - \quotefromfile demos/calqlatr/calqlatr.qml - \skipto MouseArea - \printuntil { - \dots 12 - \skipto onReleased - \printuntil } - \printuntil } - - Unlike other QML animation types, AnimationController is not driven by - internal timers but by explicitly setting its progress property to a - value between \c 0.0 and \c 1.0. - - Inside the AnimationController, we run two NumberAnimation instances in - parallel to move the number pad and the display components simultaneously to - the opposite sides of the view. In addition, we run a SequentialAnimation - instance to scale the number pad during the transition, giving the animation - some depth. - - \quotefromfile demos/calqlatr/calqlatr.qml - \skipto AnimationController - \printuntil 1; easing.type - \printuntil } - \printuntil } - \printuntil } - - We use the easing curve of the type \c Easing.InOutQuad to accelerate the - motion until halfway and then decelerate it. - - In Button.qml, the text colors of the number pad buttons are also animated. - - \quotefromfile demos/calqlatr/content/Button.qml - \skipto Text - \printuntil id: - \dots 8 - \skipto color: - \printuntil ] - \printuntil } - - We use \l {QtQml::Qt::darker()}{Qt.darker()} to darken the color when the - button is dimmed, and \l {QtQml::Qt::lighter()}{Qt.lighter()} to \e {light up} - the button when pressed. The latter is done in a separate \l [QML] {State} - {state} called \e "pressed", which activates when the \c pressed - property of the button's MouseArea is set. - - The color changes are animated by defining a \l Behavior on the \c color - property. - - In order to dynamically change the \c dimmed property of all the buttons - of the \c NumberPad, we connect its \c buttonPressed signal to the - \c Button's \c updateDimmed() function in Button.qml: - - \quotefromfile demos/calqlatr/content/Button.qml - \skipto function updateDimmed() { - \printuntil buttonPressed.connect - \printuntil } - - This way, when a button is pressed, all buttons on the \c NumPad - receive a \c buttonPressed signal and are activated or deactivated - according to the state of the calculator engine. - - \section1 Performing Calculations - - The calculator.js file defines our calculator engine. It contains variables - to store the calculator state, and functions that are called when the - user presses the digit and operator buttons. To use the engine, we - import calculator.js in the calqlatr.qml file as \c CalcEngine: - - \code - import "content/calculator.js" as CalcEngine - \endcode - - Importing the engine creates a new instance of it. Therefore, we only do it - in the main QML file, \c calqlatr.qml. The root item defined in this file - contains helper functions that allow other types to access the calculator - engine: - - \quotefromfile demos/calqlatr/calqlatr.qml - \skipto operatorPressed - \printuntil CalcEngine.disabled - \printuntil } - - When users press a digit, the text from the digit appears on the - display. When they press an operator, the appropriate calculation is - performed, and the result can be displayed using the equals (=) operator. - The clear (C) operator resets the calculator engine. - - \section1 List of Files - - \sa {QML Applications} -*/ diff --git a/examples/quick/demos/calqlatr/main.cpp b/examples/quick/demos/calqlatr/main.cpp deleted file mode 100644 index bc6e591e98..0000000000 --- a/examples/quick/demos/calqlatr/main.cpp +++ /dev/null @@ -1,51 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2017 The Qt Company Ltd. -** Contact: https://www.qt.io/licensing/ -** -** This file is part of the examples of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:BSD$ -** 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.
