When using menu with QToolButton menu is shown right under the button. Is there a way to display menu in the left/right of the button?

回答1:
The position is hard-coded in the function void QToolButtonPrivate::popupTimerDone() in [Qt install directory]/src/gui/widgets/qtoolbutton.cpp. It seems pretty hard to override that, unless you implement your own popup menu from scratch.

I know this question was answered a while ago, but I wanted to add a new answer to this question since the accepted answer is no longer valid. It is actually quite easy to change the menu position on a QToolButton. You need to subclass QMenu and override the event function. When there is a show event, just change the position of the menu.
Here is a simple example using PySide:
from PySide import QtCore, QtGui class MyMenu(QtGui.QMenu): def event(self,event): if event.type() == QtCore.QEvent.Show: self.move(self.parent().mapToGlobal(QtCore.QPoint(0,0))-QtCore.QPoint(0,self.height())) return super(MyMenu,self).event(event) if __name__ == "__main__": app = QtGui.QApplication([]) w = QtGui.QWidget() w.setGeometry(100,100,500,500) tb = QtGui.QToolButton(w) tb.setText("HELLO") tb.setGeometry(70,70,40,30) m = MyMenu("Menu",tb) m.addAction("Exit") tb.setMenu(m) w.show() app.exec_()
