How can I reimplement hoverMoveEvent for different QGraphicsItem classes without copy/pasting code for each class

[JulienMaille]

I agree this may be more a c++ question than a Qt question and i'm sorry.
Here is my problem, I want to subclass and reimplement a protected method for QGraphicsEllipseItem, QGraphicsPathItem, QGraphicsPolygonItem, QGraphicsRectItem, etc.
Is there another solution than subclassing each of them one by one?

Hi,

Depending on what you want to do, maybe an event filter could be simpler ?

[JulienMaille]

Thanks for your answer, I want to implement some tooltip on mouse hover. So idealy I would also need a few setters, not just the event reimplementation.

[SGaist]

Might be a silly question but why not use setToolTip ?

[JulienMaille]

Hum, that's not silly at all.
Well ... at first I didn't know it was so easy, so I went the reimplement way, and now I have some features I can't have just by using setToolTip

[SGaist]

What features ?

[JulienMaille]

Sorry for the late answer, I was sick.
Main features are reimplementing shape() and mouse enter/leave events

@JulienMaille
Hi
Mouse enter/leave can be handled by a event filter but
https://doc.qt.io/qt-5/qgraphicsellipseitem.html#shape
is a virtual function and it can only be handled in the class by override as its not seen by
an event filter.

Hope you are better now then :)
