removing widgets (was Re: Unidentified subject!)

[James Henstridge <james daa com au>]

It is quite possible to do this with gtk_container_remove().  Note
however by default the widget will be destroyed when you remove it because
its reference count will reach zero.

To get around this problem, call gtk_widget_ref() on the widget before
removing it so it will have a non zero reference count after being
removed.  If you do this, you must remember to unref the widget at a later
point.  I have a bit of code which does this in gnorpm (the
rpmpackagelist.c file).

James.
