[Solved]Change the view of widget when hover on QPushButton or other QWidget without inheritance

[stereomatching]

Assume that I have a QPushButton and a QTableView
When my mouse hover on the QPushButton
I want to change the appearance of the QTableView
Could I make this happen without inherit QPushButton
and override the mouseEvent(or other member function)?

This kind of mission could be done by QML in a flash
But QML is not an option before the desktop components release

Thank you very much

You can install an event filter on the QPushButton, which will allow you to preview its mouse move events without the need to subclass. I typically do that when I need to do something like make menus or palettes fly out on hover.

Note that if mouse tracking (setMouseTracking) is off for the button, you will only receive mouse events when a mouse button is held down.

Thanks to both of you
