[Glade-devel] Glade 3 GtkButton Widget

[jonf quatrefoil com (Jon)]

I am trying to get/implement the "Remove Button Contents" Functionality 
from glade-2 in glade-3, but am having little to no success.

I've attempted to change the gtkbutton.xml definition to disable the 
standard label and use_underline properties on the button, and created a 
special post-creation function to make absolutely certain that the 
button gets created with a placeholder child.

The problem seems to be that the placeholder child never gets focus, so 
  I cannot add widgets to it.  I even added a popup menu item to select 
the child of a gtk_bin, and can select the placeholder child of the 
button. However I still cannot paste, or add widgets to the button, or 
placeholder child.

What am I missing, do I need to connect signals on the placeholder?

Can anyone point me in the right direction?
