Sizing of a List Box on OS-X

[Christopher Barker]

Hi all,

I'm making a very simple little dialog that just puts up a list box and =

lets the user select an item from the list.

However, I can't get it to size right on OS-X.

With wxPython 2.6.3, it makes the list box just a bit too small =

horizontally. It seems to be not taking into account the scrollbar.

With wxPython 2.8.0, it doesn't work at all -- the size seems to have =

nothing to do with how long the strings are in the listbox.

By the way, in both versions, if you make the box beg enough that it =

doesn't need the scrollbar, it still draws something there -- a blank =

space of sorts.

Is there some other sizing call I could be making?

Sample enclosed.

-Chris
