Hello,

well it's simple ... wine's button control lacks NM_CUSTOMDRAW notification
support.

The BS_OWNERDRAWN style might have worked for Win9X but not for Windows XP -
it's handled differently (assuming comctl32 ver >= 6).
XP controls use WM_NOTIFY -> NM_CUSTOMDRAW notifications (sent to the parent)
for that purpose.
Use some windows/message spy to observe the behaviour (calc returns
CDRF_SKIPDEFAULT to indicate it draws the entire item by itself).

See:

for further information.

Implement custom draw notification messages and you will coloured buttons.

Regards
