I am writing a popup menu for a Qt push button widget. Whenever the push button is clicked, a menu pops up (below the push button).

The popup menu is left-sided below by default.

Are there any ways to make the popup menu to pop up on the right side below the push button?

There is no set position function, so I wonder if there is some sophisticated way of doing it?

Here is some code (for popup menu):

QMenu *menuMode = new QMenu(this);

min = menu ->addAction("In");

mout = menu ->addAction("out");

ui->pushButtonMode->setMenu(menuMode); //I am writing in MainWindow, that's there is ui

解决方案

This can be done by subclassing QMenu and moving the popup menu where you want to have it in showEvent:

popupmenu.h

#ifndef POPUPMENU_H

#define POPUPMENU_H
