1. TreeView problem
i'm using Win32lib 0.57.9, and i'm writing this program to browse
lyrics, play songs, put together the ones you listen to the most, etc,
and all the songs are organized by author in a TreeView, but it never
draws completely when the program starts. Only the very first item shows
up. i have to cover the TreeView up with another program or something
and switch back to it for it to redraw, but after that it's fine. what's
going on?
2. Re: TreeView problem
sounds like a repaint prolem. try using repaintWindow( TreeViewID ) when the
program loads.
also, if you use setRect() to resize the treeview, make sure the last parameter
is True (1) so
the TreeView will repaint itself when its resized.

Hi:
When I try to retrieve the text from a treeview, I get a Win32Lib error:
Error code 428
getitem requested and class not LISTBOX or COMBO
I'm using the latest stamped version of Winlib from RDS.
Is there a fix for this that I missed?
Simple demo attached.
Regards,
Irv

Many Thanks! That works fine.

Wow, I hadn't made it to that part of my code and yet somebody has already
stumbled on a problem that I would have faced down the road . . . Cool!!!
