I have a class which inherits QComboBox. I need to set red border for this widget.
I can’t use QPalette, I am trying to use setStyleSheet:
pComboBox->setStyleSheet("QFrame { border: 2px solid red; }")
It works fine for QLineEdit, but for QComboBox I got red border around popup view and not combo box.
How can I get access to the frame of QComboBox?
Ok, the easiest way, which I found to solve this problem is just to subclass widget I use and draw red rectangle in paintEvent().
