QtHandles: Qt-based toolkit with uicontrol/uipanel support

[Michael Goffioul]

Hi,

It's now publicly available on github: https://github.com/goffioul/QtHandles

To try it, use qmake (sometimes called qmake-qt4) to generate the Makefile's,
then compile as usual. Along with __init_qt__.oct, this will also compile
a tool called "octave-qt" that should be started instead of plain octave.
This tool is a simple wrapper around octave_main, but run it in a separate
thread, while creating a regular Qt event loop in the main thread. The main
reason is Mac OS X: on this platform, the GUI event loop MUST run in the
main thread, there's no way around that.

Once, you've started octave, you can enable the Qt-backend with:
graphics_toolkit('qt')

Note that this toolkit requires a current dev version of octave.

Michael.
