Finding a child widget

[rhfreeman <rhfreeman micron com>]

Probably an obvious question.

I know how to find a top level widget, given a widget child widget somewhere
below. But is it possible to reverse that?

I've got a window with a ctree (only one) in it. I know of the window. Is
there a reverse to the function gtk_widget_get_ancestor() to find a child
widget that I could use?

Cheers!
