QIcon has an "active" mode state but the widget has to support it and it
seems QPushButton does not use the active state of the QIcon during hover.
You could use a custom stylesheet, but that has the effect of needing to be
fully styled or your button looks weird.
So a pretty easy solution is to just have a custom button class, where you
have full control over what to do when hover starts and stops:
class MyPushButton(QPushButton):
def __init__(self, *a, **kw):
super(MyPushButton, self).__init__(*a, **kw)
self._icon_normal = QIcon(QPixmap("my_image.jpg"))
self._icon_over = QIcon(QPixmap("my_image_over.jpg"))
def enterEvent(self, event):
self.setIcon(self._icon_over)
return super(MyPushButton, self).enterEvent(event)
def leaveEvent(self, event):
self.setIcon(self._icon_normal)
return super(MyPushButton, self).enterEvent(event)
You can do any other settings you want in addition to changing the icon.
