[Interest] Can't catch mouse event properly from touch screen

[nus1998]

Hi All,


I'm running a Qt dialog which handles pressed/released/clicked events, when I press the touch screen and release immediatelly, sometimes there is only a pressed event, or only released and clicked events. however, if I handle the touch events by setting Qt::WA_AcceptTouchEvents, every time there are TouchBegin and TouchEnd events. it seems that Qt doesn't turn touch event to mouse event correctly. currently I use Qt 5.9.6, and I didn't seen this in Qt5.6.2


Thanks if any one can give some tips.
B.R.
