PyQt4: Move context menu to position

问题

How would you change the position of a popup menu in pyqt4? This code doesn't seem to do it.

    self.popMenu.exec_(self.table.mapToGlobal(point))
    position = self.popMenu.pos()
    self.popMenu.move(position.x() + 100, position.y() + 100)

回答1:

You version doesn't work because exec_ opens the menu synchronously, i.e. exec_ will block/wait until menu is closed. So your move is processed after the menu is closed.

You can use popup instead of exec_. That is asynchronous, so the following code will be executed while the menu is open.

Or you can calculate your desired position before calling exec_.
