A port of JVCL's TJvXPBar control that can display an icon, a header and zero or more clickable items in its client area. Use a TJvXPBar control on a form to display an XP style group box with items that can be clicked.

  • Running on openSuse 10.2 inside VirtualPC 2007 compiled with GTK 2.x (at this time doesn't work with GTK 1.x):

Note: AFAIK VirtualPC can only emulate 16 bits per pixel resolution, thats why gradient has low quality, it should see better in real monitor.

I guess the same as JVCL + Lazarus + FPC.
