Setting Label and Icon widget of Widget returned by toolbar_add_item

[Jonathan Johnson <jon maccoding com>]

Hi,

Before you all jump in and say, "Look at GtkToolButton!", I want to say 
that I don't want to support only 2.4 and up. I want to support 2.0 and 
up, since that is our previous requirement for our product, and we 
don't want to change it.

My problem is that I create a toolbar item, and at a later time, I want 
to set its attributes to something else. All of the calls that I see in 
the docs seem to be related to 2.4. I did notice GtkToolbarChild, which 
seems to be what GtkToolItem is based upon (or at least GtkToolButton), 
but I haven't had any luck with setting the properties on it. I'm not 
against using GtkToolButton if the gtk version is 2.4 or higher, but I 
want some mechanism to fall back on for systems lower than 2.4.

Any tips or links are greatly appreciated.

Thanks,
Jon
