How to reset QApplication::styleSheet for certain buttons in application?

Question

In my main() function I'm setting styleSheet on all buttons of my application.

qApp->setStyleSheet("QPushButton {"
                            "     border: 1px solid #8f8f91;"
                            "     border-radius: 4px;"
                            "     background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #f6f7fa, stop: 1 #dadbde);"
                            "     padding: 3px;"
                            " }");

But now I need to reset the style of some buttons. I've tried button->setStyleSheet(""), but it is not working. So, how to do that?

Answer 1

You can't.

What you can do is the opposite, i.e. setting the stylesheet for certain buttons like this:

qApp->setStyleSheet("QPushButton[specialButton=\"true\"] {"
                    "     border: 1px solid #8f8f91;"
                    "     border-radius: 4px;"
                    "     background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #f6f7fa, stop: 1 #dadbde);"
                    "     padding: 3px;"
                    "}");

and then:

button->setProperty("specialButton", true);

This way only the buttons with specialButton set to true will have the custom look, the others will look normal.
