Hi, i have class inherit frome QGraphicsItem, and problem is that paint function triggered only once, after this one call, i cant repaint this item even if i try use update funktion, or prepareGeometryChange. Item can be repainted only when i resize program window. I use qDebug so i'm sure that function is not triggered, and in first time, and when i resized window paint work correctly.
Any suggestion?
Hi guys,
i find cause of my problem. I used eventfilter in QObject which "control" QGraphicsItem objects, and i dont put in end of eventfilter function this: return QObject::eventFilter(obj, event); so i think that all of events were "taken" by me, and cant work correctly.
Next time i put to thread my code, maybe then somebody see error like in this case.
Thread can be close. Thx
Is the item visible? (QGraphicsItem::isVisible() returns true). Is paint() called when you change the visibility (setVisible( false ), followed by setVisible( true ))? Do you call update() on the scene or on the item itself?
Edit - our posts crossed. You are right - if your event filter eats all the events, then of course nothing can happen.
