By default, + QWidget::event() translates the first non-primary touch point in a QTouchEvent into a + QMouseEvent. This makes it possible to enable touch events on existing widgets that do not + normally handle QTouchEvent.

Note that + it is possible for a widget to receive events for multiple touch points, and that multiple + widgets may be receiving touch events at the same time. + + \section1 Touch Point Grouping + + As mentioned above, it is possible that several widgets can be receiving QTouchEvents at the + same time. However, Qt makes sure to never send duplicate QEvent::TouchBegin events to the same + widget, which could theoretically happen during propagation if, for example, the user touched 2 + separate widgets in a QGroupBox and both widgets ignored the QEvent::TouchBegin event. + + To avoid this, Qt will group new touch points together using the following rules: + + \list + + \i When the first touch point is detected, the destination widget is determined firstly by the + location on screen first and secondly by the propagation rules. + + \i When additional touch points are detected, Qt first looks to see if there are any active + touch points on any ancestor or descendent of the widget under the new touch point. If there + are, the new touch point is grouped with the first, and the new touch point will be sent in a + single QTouchEvent to the widget that handled the first touch point. (The widget under the new + touch point will not receive an event). + + \endlist + + This makes it possible for sibling widgets to handle touch events independently while making + sure that the sequence of QTouchEvents is always correct. + + \section1 Mouse Events and the Primary Touch Point + + QTouchEvent delivery is independent from that of QMouseEvent. On some windowing systems, mouse + events are also sent for the \l{QTouchEvent::TouchPoint::isPrimary()}{primary touch point}. + This means it is possible for your widget to receive both QTouchEvent and QMouseEvent for the + same user interaction point. You can use the QTouchEvent::TouchPoint::isPrimary() function to + identify the primary touch point. + + Note that on some systems, it is possible to receive touch events without a primary touch + point. All this means is that there will be no mouse event generated for the touch points in + the QTouchEvent. + + \section1 Caveats + + \list + + \i As mentioned above, enabling touch events means multiple widgets can be receiving touch + events simultaneously. Combined with the default QWidget::event() handling for QTouchEvents, + this gives you great flexibility in designing multi-touch user interfaces. Be aware of the + implications. For example, is is possible that the user is moving a QSlider with one finger and + pressing a QPushButton with another. The signals are emitted from these widgets will be + interleaved. + + \i Recursion into the event loop using one of the exec() methods (e.g. QDialog::exec() or + QMenu::exec()) in a QTouchEvent event handler is not supported. Since there are multiple event + recipients, unexpected recursion may cause problems, including but not limited to lost events + and unexpected infinite recursion. + + \i QTouchEvents are not affected by a \l{QWidget::grabMouse()}{mouse grab} or an + \l{QApplication::activePopupWidget()}{active popup widget}.
