QWidget-gestures do not work

XMLWordPrintable

    • Pass touch events 18a444c33074dd89f8855ad12dca1c55f566ff86 (stable, 1.4.2014, 5.3), 646cef5a8 (dev), 5a52faa8f (6.10), fb2db2c34 (6.9), 8db7017cb (tqtc/lts-6.8), 50e39db8c (tqtc/lts-6.5)

      Run the Gesture examples from,

      qt5/qtbase/examples/widgets/gestures/imagegestures

      Try pinch, swipe and pan. They dont work.
      Modify example to add tap and tapandhold gestures,

      grabGesture(Qt::TapGesture);
grabGesture(Qt::TapAndHoldGesture);

      Tap and TapAndHold gestures works.

      Modify example to add, nativewindows attribute,

      app.setAttribute(Qt::AA_NativeWindows);

      Now 2 finger pan and 2 finger rotate works, and weirdly these gestures are treated as Pinch gestures.
