Volume background fill

[Dave Senior]

Can any body tell me how to fill the white area shown;
  cheers.
 
 Edit :
      Styles > Button Style > GroupBox > BorderColorHint:Color (3AM,s easy way)
  or
       Buttons, Boxes &Controls- Buttons-Button-Groupbox and add this property
       -Color:bordercolor hint  and whatever color you are after.
I don,t know where else this will effect but I know I wouldn,t have figured it out, I,d better go thank some body.
 Praise the difference tool(Top of a huge list as well,my lucky day)

I don't even have that image. All I have is the trackbar on left. If you want this it's at Buttons, Boxes & Controls > Scrollbars & Trackers > Trackbar.

I had the trackbar,  i,m just going through a difference list with a theme that has that area blacked.The image is from the volume in system tray,different sound card to you maybe.
  Thanks any way,

I found it at a different spot:  Styles > Button Style > GroupBox > BorderColorHint:Color

[Dave Senior]

Thanks, thats  easier. I wouldn,t have thought of that either
