It seems that I have problem drawing ownerdrawfixed combo box, which is actually drawn in ownerdraw listbox control.
I am able to draw all items inside shown dropdown of combo box. But I can not draw anything to combo box "header".
1. What is actual message of drawing combobox "header" ? I got to conclusion that when itemID is -1 (after I call CB_SELECTSTRING) then it is "header" (Note: Seems that right rect is found in DRAWITEMSTRUCT) and I draw text than but nothing appears.
2. Currently I am trying to draw it after CB_SHOWDROPDOWN is set to true. Should it be done before that?
I'm guessing, handle the WM_DRAWITEM message in the parent window, then check the CtlID
member of DRAWITEMSTRUCT to see it's the correct combobox control, if so check the itemState member to see if it is ODS_COMBOBOXEDIT, and if so, draw the edit box (I think the edit box is what you mean when you say "header")control of the combobox.
Hope it helps.
