The \c TextBalloon class represents the individual - text balloons extending QQuickPaintedItem, the \c TextBalloonPlugin class - represents the skeleton code for a QtQuick plugin and the - \c textballoons.qml file is used to load the plugin and display the text - balloons. - - We will focus on the \c TextBalloon class first and continue with the - \c textballoons.qml file. For an example on how to implement a QtQuick - plugin please look at \l{declarative/tutorials/extending/chapter6-plugins} - {Writing an Extension Plugin} - - \section1 TextBalloon Class Declaration - - The \c TextBalloon class inherits from QQuickPaintedItem. QQuickPaintedItem - is the base class for all QPainter based items in the QML Scene Graph - framework. - - \snippet examples/quick/painteditem/textballoons/textballoon.h 0 - - To implement a QQuickPaintedItem you must implement QQuickPaintedIem's pure - virtual function \l {QQuickPaintedItem::}{paint()} which implements the - painting of the element. - - \section1 TextBalloon Class Definition - - We have to be sure to initialize the rightAligned property for a - TextBalloon item. - - \snippet examples/quick/painteditem/textballoons/textballoon.cpp 0 - - Then we implement the \c paint() function which is automatically called by - the Scenegraph framework to paint the contents of the item. The function - paints the item in local coordinates. - - \snippet examples/quick/painteditem/textballoons/textballoon.cpp 1 - - We start with setting the pen and brush on the item to define the look of - the item. After that we start drawing. Note that the \l {QQuickPaintedItem::}{boundingRect()} - item is called to draw depending on the size of the item. The rectangle - returned by the \l {QQuickPaintedItem::}{boundingRect()} function is the size - of the item as defined in the QML file. - - \section1 textballoons.qml file - - The Interface consists of two main parts. The scrollable area with the - textballoons and the controls button to add new balloons. - - \section2 BalloonView - - \snippet examples/quick/painteditem/textballoons/textballoons.qml 0 - - The balloonModel contains two elements at application start which will be - displayed by the balloonView. The balloonView alernates the TextBalloon - delegate items between left-aligned and right-aligned. - - \section2 Controls - - \snippet examples/quick/painteditem/textballoons/textballoons.qml 1 - - The controls part of the UI contains a rectangle with a MouseArea which - changes color when the mouse hovers over it. This control 'button' adds - a new element to the end of the model with a random width. - - */ |
