[PyQt] Working example of QMenuBar on OSX? Examples don't work

[Marcel Maré]

Hi

Think I found out some more. 

To rule out a programming error on my part (bering new to Qt) I only looked at the menus.py example (Qt/examples/mainwindows/menus.py). 

The relevant menu definition sections is like this:

def createMenus(self):
    self.fileMenu = self.menuBar().addMenu("&File")
    self.fileMenu.addAction(self.newAct)
    self.fileMenu.addAction(self.openAct)
    self.fileMenu.addAction(self.saveAct)
    self.fileMenu.addAction(self.printAct)
    self.fileMenu.addSeparator()
    self.fileMenu.addAction(self.exitAct)

    self.editMenu = self.menuBar().addMenu("&Edit")
    self.editMenu.addAction(self.undoAct)
    self.editMenu.addAction(self.redoAct)
    self.editMenu.addSeparator()
    self.editMenu.addAction(self.cutAct)
    self.editMenu.addAction(self.copyAct)
    self.editMenu.addAction(self.pasteAct)
    self.editMenu.addSeparator()

So, since it uses self.menuBar() it should not be compatible with the system menu on OSX, since it does not use QMenuBar(). 

Wat I found out that is that when I run the program the menu is visible but unclickable (as reported earlier). However, when I switch to some other program and then back to the menus.py program the menu works!
Looks like a bug to me.
