I keep working on it, which is nice. I have finished the skeleton of the implementation of a Qt driver for the CD canvas.
I had it kinda working with the generic X driver, but it sucked a bit to have this largish chunk of Motif code I didn't understand in the middle of it all.
It has only the most basic stuff implemented, and the scrollbar stuff is not there, but it does draw and set colors ;-)
So, right now, the next step is getting the iupcontrols library up, but that shouldn't be too hard, I think.
But, we'll see.
PS: If anyone reads this and wants to check it out, just email me, I can ship it.
