call to SetMenuBar() kills sizer layout- (Further modification to Sizer Tutorial)

This is a further mod to Mike Driscoll’s sizer tutorial from here
http://www.blog.pythonlibrary.org/2008/05/18/a-wxpython-sizers-tutorial/

After following Cody’s suggestion i- from my previous post regarding Mike’s Sizer Tutorial …
I’ve added a menu with two menu items.

When I call self.SetMenuBar(), the sizer layout gets compressed to the upper left corner.

When I comment out this call in MyForm().init()

THIS LINE KILLS THE SIZER LAYOUT

    self.SetMenuBar(self.mainMenuBar)

THIS LINE KILLS THE SIZER LAYOUT

the layout looks like what I would expect.

Any help to what I’m doing wrong is appreciated.

Thanks

Including the call causes layout problems- I don’t see why.

I’ve made menus before and didn’t have this issue.

Just move the " self.SetMenuBar(self.mainMenuBar)" line to the end of the init method and it should work. At least, it did on my machine. I don’t remember why that works though.

Yes, this works for me.
It would be good to understand why,

I have my code to generate the menus in their own methods, to help keep init from being so cluttered,
I guess it wont hurt to pull one line out and move that to the end of init()

The panels own size is being managed by a sizer 'topSizer' while the
frame is not using a sizer to manage the panel. If you put the panel
'self.panel' in a sizer and then set that as the frames sizer it will
also fix the layout. Since without a sizer the frame will only manage
the layout of its first child.

Aha! I knew it was something simple like that!
