Colorized background of a Tab Control

[Jim Seekamp]

I'm trying to colorize the background of a tab control (NOT using DDT). I tried using a DDT example but it doesn't work when creating a window with createwindow...
I have no problem changing the color of the actual tab (on top), but the window underneath it is the problem!

This is how I'm trying to do it:

       case %wm_erasebkgnd
         ''draw tabs with a differnt gradient background color
         hdc&=wparam&
         pg&=getcurseltab(htab&)
         drawtabbackground hdc&,hwnd&,pg&
         function=1
         exit function

This part works great (the actuual tab):

       case %wm_drawitem

         if wparam&=1000 then  ''tab control
           disptr=lparam&
           pgnum&[email protected]

           bcolor&=rgb(128,128,255)

           if @disptr.itemstate=%ods_selected then
             @[email protected]+2
             fcolor&=rgb(255,255,255)
           else
             fcolor&=rgb(0,0,0)
           end if

           hbrush&=createsolidbrush(bcolor&)
           selectobject @disptr.hdc,hbrush&
           settextcolor @disptr.hdc,fcolor&
           setbkcolor @disptr.hdc,bcolor&
           fillrect @disptr.hdc,@disptr.rcitem,hbrush&

           ti.mask=%tcif_text
           ti.psztext=varptr(ztext)
           ti.cchtextmax=sizeof(ztext)

           call tabctrl_getitem(getdlgitem(hwnd&,wparam&),@disptr.itemid,ti)

           style&=%dt_singleline or %dt_center or %dt_top
           drawtext @disptr.hdc,ztext,len(ztext),@disptr.rcitem,style&
           deleteobject hbrush&

           function=1
           exit function
         end if

The drawtabbackground:

sub drawgradient(byval hdc&,byval hwnd&,byval pgnum&)
     dim rc as rect
     getclientrect hwnd&,rc
     bcolor&=rgb(128,128,255)
     hbrush&=createsolidbrush(bcolor&)
     fillrect hdc&,rc,hbrush&
     deleteobject hbrush&
end sub

Any ideas???

Ownerdraw only draw the Tabs of the tab control, not the background of the complete control.

To draw that, subclass the control and then process the WM_ERASEBKGND message.

Thanks Chris
That explains it.
