What do you want exactly? You might want to use a QMessageBox to show a selection when the clicked-signal of the QPushButton is emitted. With QPushButton::setMenu(...) you can set a popup menu which will be shown automatically when the user clicks the button.

I can just guess what you're trying to achive, but I think a using a member variable would be a better choice.
