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
