Antonio,
There seems to be a small bug in the new TOulook2003 class. In the AddGroup() method there is no dialog creation like there is in the New() method.
I think this code needs to be added to the AddGroup() method:
DEFINE DIALOG oDlg OF Self STYLE WS_CHILD ;
FROM 33, 0 TO ::nHeight - ( Len( ::aGroups ) * 32 ), ::nWidth() - 1 PIXEL ;
FONT Self:oFont
AAdd( ::aDialogs, oDlg )
[This is the same code that is in the New() method.]
Or, the code needs to be made into a new AddDialog() method and called from both the New() and AddGroup() methods. This is probably a better solution.
Regards,
James
