QPushButton - not working setIcon in Active state

dr.ew

QIcon icon;
icon.addFile(":/25.png", QSize(), QIcon::Normal); - ok
icon.addFile(":/25_hover.png", QSize(), QIcon::Active); - fails
icon.addFile(":/25_disabled.png", QSize(), QIcon::Disabled); - ok

QPushButton button;
button.setIcon(icon);

When mouse hover the button (button is Active), but icon of the button in state Normal, why?

The Active state can mean different things for different widgets. For push button hover and active are two different things. A button becomes active when it has focus (e.g. after a click or via keyboard tabbing to it). Hovering is not the same as it can occur over an inactive button too.
To style a button when mouse hovers over it you can use a stylesheet.

Sorry, Chris, do you know when QCheckBox becomes Active?

bq. do you know when QCheckBox becomes Active?

An intuition would suggest the same situation - clicked or navigated via keyboard, but apparently it doesn't respect the icon change on that soo... I don't know. Possibly a Qt bug?

Finally, I haven't could learn, when QCheckBox becomes Active and solved the problem via inheritance from QCheckBox.

Stylesheet for QCheckBox is very limited.

Thank you for help!
