Has anyone written code for, or even just seen, a 2-D slider widget?
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).
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..!

I used to use wxWidgets, but I switched to FLTK.
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;
This should be trivial in any Toolkit, a matter of minutes I believe. ;)

This might be a bit trickier, depending on the shape of the bitmap,
but a circle should be trivial too.

you might want to check out PHAT. it has fan-sliders and other crazy stuff and is geared
towards GTK+ audio interfaces.

applications, like

Oh yeah... x-y controllers. Nice. I'll have to add one of these to
PHAT.
Peace out,

Pete,
You might like to look at a demo program I made as part of my GTK+
education - it's a functional xy-controller:
http://www.skynet.ie/~jmmcd/software/xy-controller.tar.gz
But I actually made the xy-controller directly from the drawingArea
widget. Ie, I didn't make a new reusable widget (maybe it'll inspire
you to do that for PHAT), because that seems like a lot more work!
Maybe when I learn a bit more...

I appreciate the code, James. Is this stuff GPL'd or some-such?

Yes, it's based on the GTK+ tutorial "scribble" program, which is GPL.
Thanks Marije for pointing out SuperCollider SCUM - will check it.

Hello James,
take a look at the SCUM code (GUI for SuperCollider) of Stefan Kersten,
he made a 2D-slider in FLTK.
sincerely,
Marije
