closing Dialog doesn't exit the app

With this example code the dialog is closed when pressing the "X" but
the app is still running. Shouldn't there be a default close handler
that exit the app because this is the TopMainWindow?

[code]
#!/usr/bin/env python3
import wx

class FooDlg(wx.Dialog):
    def __init__(self):
        super(FooDlg, self).__init__(None)

        self.ShowModal()

if __name__ == '__main__':
    app = wx.App()
    win = FooDlg()
    app.SetTopWindow(win)
    app.MainLoop()
[/code]

Hi,

With a wx.Dialog you need to call its Destroy method or do something like this.

#!/usr/bin/env python3
import wx

class FooDlg(wx.Dialog):
     def __init__(self):
         super(FooDlg, self).__init__(None)

if __name__ == '__main__':
     app = wx.App()

     with FooDlg() as win:
         win.ShowModal()
     app.MainLoop()

"ShowModal" starts its own main loop. That function will not return
until the dialog is closed. You won't even execute "app.SetTopWindow"
and "app.MainLoop" until the dialog has closed, and by that point there
are no windows left to generate a message to tell app.MainLoop to exit.

If all you want is a modal dialog, you don't need your own MainLoop at
all. Just do this:

class FooDlg(wx.Dialog):
    def __init__(self):
        super(FooDlg, self).__init__(None)

if __name__ == '__main__':
    app = wx.App()
    win = FooDlg()
    win.ShowModal()
