Currently, QT on MeeGo does not support multitouch, the pinching does not work in MTF application. But all single touch gestures can be captured by MTF application.

Try running widgetsgallery and see if you can pinch-resize the image in simple widgets -> image widget. If yes, then most probably everything is ok with your touch events.

But, a MTF touch function can work well. Does it mean QT can read touch events in my device?

First of all you could check if you receive QTouchEvents in your event() methods. If you don't get them, chances are that there is something wrong with the way Qt can read touch events in your device. In such case gestures won't work.

An example is the imagewidget(http://doc.qt.nokia.com/4.7/gestures-imagegestures.html) I built the imagewidget application, and ran it on a Netbook with a touch screen(MTF application can work well). It can run successfully, but does not work for touch. I touch on the screen, but no effect. I debugged the application and found that on the 'event' function of imagewidget as follows: bool ImageWidget::event(QEvent *event) { if (event->type() == QEvent::Gesture) return gestureEvent(static_cast<QGestureEvent*>(event)); return QWidget::event(event); } There is not any one execution branch of "event->type() == QEvent::Gesture". All QEvents are submitted to QWidget:event(). So what is the problem? Thanks -Weiliang
