[pygtk] Custom button for Combobox

[Ubitux]

Hi,

I'm trying to do this :
http://www.pygtk.org/pygtk2tutorial/figures/comboboxwrap.png but I
would like to have a customised button. The popup() method does not
seem to work when I connect it to a customised gtk.Button() if the
combobox is hidden (in fact I just want to have the button of the
combobox hidden).

Maybe there is other way to do what I want. I had a look to gtk.Menu()
but there is not wrap mode like the combobox has (to have the same
render of the screenshot above). Another thing I tried is to use the
set_active() method on the item I always want to have by default on
the button. But the problem is that the 'changed' signal does not work
on the default item (of course). It seems there is no 'selected'
signal which act as the 'changed' one but with the unchanged item
too...

So if you have any idea, I'll be very gratefull, it's been a while I'm
on this problem...

Another thing : I think I found a mistake in the documentation while
looking for my problem. On this page :
http://www.pygtk.org/docs/pygtk/class-gtkcombobox.html the propery
"popup-shown" is marked as Read-Write, but it seems to be readonly :
TypeError: property 'popup-shown' is not writable.

Thanks.
