c++ - Determining Qt stylesheet options programmatically?

Question

Is it possible to look up stylesheet values at runtime in Qt?

I'm working on a custom button derived from QPushButton that has some stylesheet properties set. I'd like to be able to look up some stylesheet settings like border width, margin, padding-top, padding-left, padding-right, etc. Is this at all possible to do without calling widget->getStyleSheet() and parsing out the values myself?

Answer 1

Internally, when you call QApplication::setStyleSheet() Qt creates a QStyle sub-class called QStyleSheetStyle.

That means you can query style sheet information via the normal QStyle methods. Just remember to fill in the options and widget parameters properly to ensure you get the right values from the style sheet.
