QWidget won't close!
Message 1 in thread
Hi All,
I tried to close my widget by close() function but it didn't work!,
the widget disappeared, but its process still exist!
So I'm asking you about a way for forcing the widget to be completely
closed, could you?
By the way, I tried to use setAttribute(Qt::WA_DeleteOnClose, 1) but it
didn't affect on closing process.

Hi Muhammad,
On Windows, a process does not close until all of its threads have been stopped.
Do you have any threads in your app?
Hope that helps,
Tony Rietwyk.

No but I've a timer and I call timer->stop() before close the widget.

Try just deleting your widget instead of closing it.

Should work, but I guess it is not instantaneous. So, if you don't give Qt
the opportunity to do it for you, it will not.

Hi Muhammad,
In the main routine, do you have something like (where a is the QApplication object):
a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
or
a.setQuitOnLastWindowClosed( true );
Otherwise, there is nothing to stop the application event loop.
Hope that helps,
Tony Rietwyk
