oops I was too trigger happy.
Installing the event filter on the top level widget triggers the filter
_after_ the tooltips were shown for some reason.
Only when I install it on the QApplication instance do I get a chance to
filter before the default event.
Oh well, back to using enter and leave events to install and remove the
filter I guess.

DOH, ignore that last bit.
I wrongly assumed that I need to install event filters to QApplication
instances when in fact I can install them to any QObject.
So there is no need to mess with enter and leave events.
Nice

Thanks guys, works perfectly.
Since my app will run inside of another host application I just need
to make sure to install the event to QApplication.instance()
in my main widget's enterEvent and uninstall it again in the
leaveEvent to avoid processing the host application's events.
But that should be ok, right?!
Thanks again!

Is there any way to intercept a any tool tip even from anywhere

Install a global event filter on QApplication, and filter out all
QEvent::ToolTip events? (Never tried myself, so take it with a
grain of
salt.)
Yes. That is how I have been doing it for years.
class GlobalEventFilter : public QObject {
Q_OBJECT
typedef QObject BaseClass;
public:
GlobalEventFilter( QObject *parent ) : BaseClass(parent) { }
protected:
bool eventFilter(QObject*,QEvent*);
};
bool
GlobalEventFilter::eventFilter( QObject *op, QEvent *ep ) {
if( ep->type() == QEvent::ToolTip &&
!CommandLineArg::s_DoToolTips )
return true; // Filter out.
return BaseClass::eventFilter(op,ep);
}
...
GlobalEventFilter *mp = new GlobalEventFilter(s_QtApp);
my_qt_app->installEventFilter(mp);
...

Another option: install a QProxyStyle and return a wait period for
showing tooltips ridiculously high (INT_MAX).
HTH,
