We're looking at a WIDGET_HTML control for a future IDL release. Windows and Mac are already working, but it's been tricky to get it to work correctly on Linux.

I agree with Russell, and to extend this idea, I'm wondering if we should introduce a set of drawn widget controls to IDL. We already use them all over place in ENVI. Their advantages are: they'd look nice, they'd work within the current widget API and they'd work across platforms*.
*Except when they don't because of the vagaries of graphics hardware support. This would be the big drawback of this idea.
What do you think?

Grr... That sounds tricky and I'm unaware of anything to do this automatically. You could try to kludge it, here's what I would try...
Instead of using widget_label or widget_text, I'd use a widget_draw. Then set the background color to [192,192,192] and foreground color to some shade of blue. Then have it detect events based on mouse click. In the event handler, have it know to then spawn a web-browser with the correct webpage. Heck, you could make this a compound widget, which once the first click is detected, you change the foreground color to purple. (call it cw_hyperlink.pro) Of course, sizing the draw window and placing the text properly might be tedious, but should be possible.
Good Luck though, I think you'll need it...
Russell
