When you say 'Qt side', I hope you mean J code making calls to the Qt
interface. That's what I think I need.
When I follow the link on the Qt Install page to
http://www.jsoftware.com/gitlist/qtide.git/
it fails with the message
RuntimeException: fatal: Failed to resolve HEAD as a valid ref.
Is there a way to use TortoiseSVN on the Qt code, or is git something
completely different?

It depends on whether you want to do it on the j side or the Qt
side. For the J side, it is simple, just uses wd and gl2
commands. For the Qt side, you need to subclass a QWidget and
create a QPainter and also a QImage/QPixel if you want double
bufferring. git-clone or browse the gtide git repo in particular
the files isigraph* and gl2* under the lib/wd folder.

I am interested in using Qt as the graphics base for my dissect
program. I need to be able to create a form, and in that form have
an isigraph where I can use the full power of Qt (or at least, manage
the layout of the screen using the Qt primitives).
Where should I look for examples of how to do this? I am
particularly interested in:
how to create a canvas (part of a form, I assume)
what the graphics commands are to lay out widgets
what the commands are to paint the screen
how resizes etc are handled
how do I get click information. In particular, if I have a multiline
text field, I assume that Qt would give me some way to know what
character was clicked.
I can slog through the Qt docs, but any pointers for J code would be
much appreciated.
