Re: [wxhaskell-users] How do I call statusBarSetStatusWidths :: StatusBar a -> Int -> Ptr CInt -> IO ()

[David B. <d....@co...>]

Because I didn't know about it!  I was looking in Controls for a status bar
wrapper, not Menus.  None of the samples had status bars and I wanted to
start off by doing something that wasn't in the samples.  I guess I need to
browse *all* of the documentation so I have a better idea of what's where.

Thanks for your help!  -- David
