Unsolved Twice QWidget::TouchBegin event
-
I wrote an application for raspberry with qt 5.3, raspbian jessie and a 7-inch touch screen.
In my application I need to override the QWidget::event method. And everything was worked ok.
My problems start when I ported my code to raspbian stretch with the qt 5.7.1.
Now my code doesn't work because the QEvent::TouchBegin event is sent twice time.
Do you have any suggestions?Code
bool Zone::event(QEvent *e)
{
if (e->type() == QEvent::TouchBegin) {
qDebug("TouchBegin");
.........
return true;
}if (e->type() == QEvent::TouchEnd) { qDebug("TouchEnd"); ..... return true; } if (e->type() == QEvent::MouseButtonPress) { qDebug("MouseButtonPress"); ..... return true; } if (e->type() == QEvent::MouseButtonRelease) { qDebug("MouseButtonRelease"); ....... return true; } return QWidget::event(e);
}
Output
TouchBegin
TouchBegin
MouseButtonPresseds
TouchEnd
MouseButtonReleased
