The perspective chooser buttons are SWT ToolItem controls created with
style SWT.TOGGLE. I don't think I understand how your requirement
differs from this. If you want this same effect on (for instance) a
wizard page or dialog then I would suggest using a similar approach,
even if it means creating several ToolBar controls each containing only
one ToolItem. The "sunken" look is done natively, so I would not
suggest trying to replicate it manually.

Thanks for your help. The SWT ToolItem rings a bell from a couple of years ago, when I was trying to (mis?)use the underlying toolbar that perspectives uses, in an RCP app.
I don't think I can put a toolbar right in the middle of a Composite.
[edited: The above statement is completely wrong! The parent of a Toolbar is a Composite. So, I have replaced the use of a label descibed below, in my 'button part', with a ToolItem and selection listener. It works fine. Takes up a bit more screen space, but the 'selected' state is clearer. The label solution, does work and could be the answer if you have a lot of buttons and screen space is constrained).]
I've come up with an initial solution. I have 24x24 icon images for the types I want to select from. I've created a row of these 'buttons' using Labels-with-image, and a spacing of 1 pixel. Each 'button' has a mouse-down listener which toggles the image between: 'changed with SWT.GRAY' to produce a disabled look - which gives a reasonable illusion of being depressed, and the default image, as unselected.
