I finally got it solved... The fix was: QPushButton { width: 100%; } :- )

@Dariusz said in How to get this style on a button: @JKSH AH yes, could do... but I'm trying to css entire app with hundreds of buttons/etc.. I think you could inherit from the QPushButton then: class MyButton : public QPushButton { MyButton( ... ) : ... { setMinimumSize( ... ); } };

@mrjj Yes, sorry :D

@raven-worx For me, it seems as it is working. The above code is actually taken from ProxyStyle web page from Qt's website, I just replaced QStyle::SH_UnderlineShortcut with QStyle::SH_ComboBox_Popup. So, I think it is a good approach. Subclassing QComboBox would become quite cumbersome as I will have to promote all the combo boxes in my UI to the subclass.

@Gojir4 said in Styling the QMdiArea using the the fusion style and QPalette (dark theme): darkPalette.setColor(QPalette::Disabled, QPalette::Shadow, QColor(r, g, b)); (Edited) tried, but it didn't work. I suspect that underneath it's a QLabel with a raised text but I don't know how to set the color of those using QPalette
