Qt in AI Panel on MAC: Keyboard events/focus issue

bunny351​ was this your final solution? It doesn't work at all on my side. Although the problem on my side might be a bit different, as it does work sometimes. This is my thread, if anyone of anyone of you has a suggestion it'd be great:macOS Qt QLineEdit/QTextBox Focus Issue

There is a crude workaround that seems to work for me.

I subclass QLineEdit and override QWidget::macEvent for detecting mouse events. On a button press I activate

the window and set the focus manually:

#include <Carbon/Carbon.h>

bool MyLineEdit::macEvent ( EventHandlerCallRef caller, EventRef event )
{
 if(GetEventClass(event) == kEventClassMouse) {
   if(GetEventKind(event) == kEventMouseDown) {
      activateWindow();
      setFocus(Qt::OtherFocusReason);
    }
  }
  return false;
}

I admit that this is not a perfect solution, but at least it gives you /some/ sort of usable behaviour.

I didn't succeed to use QMacNativeWidget properly since Qt 4.7 and Qt didn't fix this bug. I used Objective-c++ instead.

Did you try with Qt 5.3 ?
