How can I use Qt5 in my own mainloop?
-
before, using Qt4 I had installed a hook on X Display such as (from InitQtEvents()) :
@static QApplication* QtApp;
Display*
HookXDpy (XDpy* xd, XEventProc p)
{
if (!xd)
xd = XDefaultDpy;
if (!xd)
return 0;
xd->evproc = p;
return xd->dpy;
}static void
HandleXDpyEvents (XEvent* event)
{
QtApp->x11ProcessEvent (event);
}void
InitQtEvents ()
{
Display* dpy;if (QtApp)
return;/* Qt app creation, with our own X11 server connection so that
we can handle the connection in our main loop
*/
dpy = HookXDpy (0, HandleXDpyEvents);
QtApp = new QApplication (dpy);
}
@I had created the hook and give the X11 connection to Qt4 application and then process XEvent.
How can i do this in Qt5 ?
because it seems that QXcbEventReader opens a connection on the same X11 socket (IN another thread) AND eats every xevent ! to send them back to it-self as PostedEvents !
What should I do now to get all xevent in my own mainloop and process them to my QApplication?
I haved already tried to:
- reimplemented QcoreApplication::notify() but I don't receive any native Events when i try to resize my QFrame .. and it also doesn't repaint itself anymore.
- added NativeEventFilter and EventFilter on my QApp but it's the same as above ... I do not receive any interesting events

Hi and welcome to devnet,
I'd advise to bring that question to the interest mailing list. You'll find there Qt's maintainers/developers (this forum is more user oriented)

Thank you for the advise
I will try this opttion :)
