popup modal dialog does not have focus on touch screen
-
So you have to click once inside your non-focused dialog with your mouse (focus + button click at once) but twice (first tap focus, second tap to press button) with a finger on your touchscreen?
A tap on screen will trigger QTouchEvents and not QMouseEvents directly. There could be something wrong...
Have you tried to debug / print the QEvent, which you get from one single tap on your dialog?

Have you checked the result of the
QTouchEvent?
IfRaise,Focusand so on are connected to the QMouseEvent and not to theQTouchEventdirectly, maybe you have to emit or trigger some signals / events to have the same effect on finger tap as on mouse click.
If debugging is the process of removing software bugs, then programming must be the process of putting them in.

It is set and QTouchEvent can be received. Event filter is added to the buttons and dialog for QTouchEvent. Now one press on the touch screen activates one button. It works now. Thanks a lot for your tip.
However, the touch event can be received only for the dialog, but the buttons when the exact code is used to pop up the dialog from another main window.
I still think the focus is the root cause. The pop-up dialog simply can not get the focus. -

Hi
I would try without the line
setWindowFlags((Qt::WindowFlags)(Qt::Window | Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint));
and see if still the same.Also, i would qDebug()
QWidget *QApplication::focusWidget()
to see who got the focus then.What platform is this on ?

@mrjj It is on Ubuntu. The flag settings are as follows:
setWindowFlags((Qt::WindowFlags)(Qt::Window | Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint));
I checked the focus widget which is on a button inside the main widget. The problem is why the pop-up dialog or its children can not get focus? -
Add event filter and handle press event. Then check event position and you know which button is clicked.
@JoeCFD Not yet.Did you solve it?
