It is.
Not a huge one, but I wanted an app that was as quick as I could reasonably make
it. Plus I wanted to play lower down the stack...

OK - so when I want to do something 'objecty' with it I cast it to that kind of
object.

Not clear from the docs..
http://library.gnome.org/devel/gtk/stable/GtkToggleButton.html
says:
  gboolean            gtk_toggle_button_get_active        (GtkToggleButton
*toggle_button);

Which is technically correct but not best practice then?
Ah, I now see that it's mentioned in passing in the example. But it's not clear
in the api _specification_

Ah, I've also seen where it's declared when you make your own widgets... OK.
I'll do some rejigging and see how it turns out - thanks :)

OK

This is still the old scratchbox1 SDK?
(I was hoping to be late enough to the game to miss the migration - I guess not
<grin>)
I'm using sdk+ on a Debian desktop for the other app.
If there's any interest then I'd be happy to help test the Qt4.
I've also just started throwing up Xen domains so I can have a few SDK vboxes..

Anyhow - downloading...

Yell if you find it...

I think perhaps that is the issue - OO gui toolkits and C have a bit of an
impedance mismatch.

button.set_text("sometext");
