QApplication::flush() doesn't work.

[jthacker]

hi guys..!

i'm working on an embedded touch screen device which is little bit of low clock freq...
so when i push tool button twice or thrice, so the event is getting stored in a que.
but i don't want that que.
so at the end of the tool button slot i added qApp->flush();
but events are not getting flushed.

what to do ?
can u help me in this?

thanks
