Has anyone written code for, or even just seen, a 2-D

What toolkit was it in? Do people around here prefer QT to GTK+, or
vice versa, and does anyone use FLTK, or something else?
I think the ideal widget would allow the user to click or
click-and-drag a cursor around the 2-D area, returning x and y
coordinates of course; and would allow a bitmap to be displayed
underneath the cursor; and would allow some way to constrain the
cursor movements (eg within a circular area inside the widget).
you might want to check out PHAT. it has fan-sliders and other crazy stuff and is geared
towards GTK+ audio interfaces.

Such a thing would be great for lots of audio
applications, like
controlling filter cutoff and resonance at the same time. That's what
I'll be doing, only a bit more complicated..!
