You could put the picture of the metal into the tab control, select the
picture and press Ctrl-Shift-J to put it in the background and then add
your controls over it. It will make the pages in the tab look
like the metal, but I am not sure if you can actually change the tabs
themselves to look like metal.
ye ma8, figured out about that one, its not very cool tho eh!! 😕 it looks pretty rubbish if im being honest. och well, maybe one for future versions, where you can skin yourtabs to emulate a plethora of hardware caseing. that would be cool actually
You could make that look a little better if you used a picture for the tab controls. Right-click the tab and select Advanced->Tab Layout->Import Image from Clipboard. (I assume that's already the Classic Tab Control in Kenny K's image.)
