See the attached sample program. I include a BMP file which is used by it.
Put the two in the same directory and then run "python tree.py -d". This is
what you get if you *don't* specify the wxTR_HAS_BUTTONS style - notice that
the root has a little '+' next to it, to expand it, and an icon as well.
Now run "python tree.py" (no -d). This is the same, but with
wxTR_HAS_BUTTONS specified. Now, the little '+' has gone!
While I'm happy enough that I can get both behaviours depending on the style
I set, the reality differs from the documentation, which says
"""
wxTR_HAS_BUTTONS Use this style to show + and - buttons to the left of
parent items. Win32 only.
"""
This seems to be the exact opposite of what I am seeing...
Is this just a documentation bug? (I'm running Python 2.1, wxPython 2.3.1,
on Windows 2000, BTW).
