@wavelike said: don't they use QComboBox-like widgets to offer different colors, brush thickness etc? Hm, I guess that's true, but I'd say it has more to do with QMenus and QToolButtons than QComboBox. But then again they are indeed similar in some ways. Oh well, the important thing is it's doable and quite easy ;)

Hi, You can try implementing a QStyledDelegateItem and paint only the icon. Hope it helps

@mrjj @jsulm Thanks you for your replies. As it turns out, the crash I mentioned was actually caused by a subtle, yet important bug in our test infrastructure: we have a special fixture that will instantiate and destruct the QApplication instance before respectively after each test case. We initiated the argc and argv parameters with variables local to the constructor. For some reason creating a QIcon causes Qt to access argv, in other words: a crash. Short story: both your suggestion, but also my original approach work perfectly!

@Aram Its completely ok. Just mark it as SOLVED and all will be happy

Hi, you can store the old values and restore them later class MyWindow: public MainWindow { .... private: QSize _originalSize; }; void MyWindow::changeIconSize() { _originalSize = iconSize(); setIconSize(...); } void MyWindow::restoreSize() { setIconSize(_originalSize); }
