Hi and welcome to DevNet,

Could you show the code of your event filter ? You most likely eat all events in there so the button probably misses QEvent::StyleChange

Hope it helps

foxgod

my code is
@
bool ViperFrame::eventFilter(QObject *obj, QEvent *event)
{
if(obj == this)
{
if (event->type() == QEvent::MouseButtonPress)
{
m_aFrame->hide();
return true；
}
}
}

Edit: Again, @ tags around code sections please; Andre

Don't omit return value. This is undefined behavior and it's a shame that some compilers allow you to compile that.
Explicitly return false at the end of your eventFilter.

Also, as SGaist said, you are eating the event by returning true. You should probably return false to let Qt handle it properly or call the base implementation yourself.
