[news.eclipse.platform.swt] Use slider/scale to select extended range

[ianmayo@xxxxxxxxxxxxx (Ian Mayo)]

Hi all.
I'm using a scale to allow user-control of time.  It works just fine.

I'd like to introduce a user control/controls to allow users to select a 
period of time (start/stop points).

I picture a UI whereby the user holds down the shift-key and drags the 
scale, with the selected portion of the scale appearing shaded/highlighted.

This functionality doesn't appear to be in the API, and the scale widget 
isn't meant to be sub-classed (wherein I could implement my chosen 
behaviour - even though I'd rather not...).

Can anybody provide me with any pointers?

Cheers,
Ian.
