Why my application doesn't exit even frame.Destroy()?

wxPython Users

I call self.Destroy() at main frame's menu event handler. But I found
sometimes, program will still exist.

My code is very simple:

        if self.tbicon is not None:
            self.tbicon.Destroy()
        self.Destroy()

Should I call wx.Exit() to force program exit?
Thanks.

I found the reason, it is because I have a modal dialog showed. I call event
handler from taskbar icon's menu, then the application won't exit. I think
this is because the dialog is still alive.

But... how can I prevent this situation? check wx.ActiveWindow() before call
self.Destroy() ???

Thanks.

Or set some flag that can be checked before showing the taskbar icon's menu, and then use that flag to disable that menu item while the dialog is active. This way you'll never get as far as calling the Destroy because the user will not be able to choose the menu item.

Or if you don't like that then you can get the list of top level windows with wx.GetTopLevelWindows() and just close them all.
