if i create more items in treeview and then delete them all and
again create two items it crashes. look at attached example.
i tried to debug win32lib but it's hard.
this removes bug in this example program
but it still crashes in more complicated program (edsgui):
In win32lib in fDoTVN_GETDISPINFO ():
-- This is called before we get the handle, so if
-- we haven't filled it in yet, we'll just grab
-- the first one.
if not lItem=20
then
lItem =3D find(0, tvitem_handle )
=20
-- Start Tone Skoda
if lItem =3D 0 then
tvitem_handle =3D append (tvitem_handle, 0)
lItem =3D length (tvitem_handle)
for i =3D length (tvitem_data) to lItem do
tvitem_data =3D append (tvitem_data, {0, 0, 0, 0})
end for =20
end if
-- End Tone Skoda
end if

3. Re: treeview bug
Matt, now it crashes even sooner. Now, I don't know if I inserted your patch
right. Maybe I can just wait for next release of Win32Lib, where this bug
will be fixed? I have some other things to do anyway.
