Hello everyone,
I'm trying to integrate Qt5 in my own mainloop.
before, using Qt4, I had installed a hook on X Display such as (from
InitQtEvents()) :
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 xevents sent, starving my connection which
receives nothing anymore, and 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 if
necessary to QApplications?
I haved already tried to:
reimplemented QcoreApplication::notify() but I don’t receive any native Events,
for exemple: when i try to resize my QFrame .. so it 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
Any advice will be nice.
thank you.
