qpushbutton

问题 I'm fairly new to C++ in general, so I need a little help with Qt. I'm trying to add an image to a PushButton, and I keep having problems with it.

问题 I set corner widget into QMenuBar that has two QPushButtons. But when I set long text by button's setText, button doesn't change it's weight, so, icon and part of text hiding.
