I've found in the past that GTK and Glade in particular does some
unexpected things in order to achieve the results we take for granted.
ToggleToolButtons, for example, are incredibly convoluted - partly so of
what Glade creates, and partly because of how GTK maps them. If someone
needs more details about them I can point you to the xseq code that
manipulates them for buttons.

A more mundane example is a "simple" stock button like OK. In actuality,
GTK takes the stock button request and forms an Image plunks the OK
pixbuf into it, then forms a Label, plunks "Ok" into it, and then makes
an HBox, packs the Image and Label into the HBox, and then stuffs the
HBox into the Button.

Sometimes, after much hair-pulling, I've found myself rendering
something, and then calling the Widget's getChildren() method, then
walking the Widgets returned, and so on down until I learned what the
heck was in there.

Usually you can get some insight by reading the .glade file. Just pull
it up in a nice syntax highlighting editor, and look at the families of
widgets it has created. [Keep in mind that GTK could further complicate
things at runtime]
