Hi Lance,

The GtkDialog documentation tells only how to access the action area, not 
its children. Searching around I see a gtk_container_get_children() which 
presumably returns a list of GtkWidget pointers. Is there a way I can look 
at a widget pointer and detrmine the widget's type, i.e., figure out 
whether or not it's a button? I see references to a gtk_widget_get_type() 
on the web, but no good examples of how it's used, and it appears to be 
not present at all in my own GTK release's GtkWidget documentation. There 
also seem to be some related type discovery functions in the gobject 
library such as g_type(), etc., but so far I have not found any useful 
examples of how I might use them to figure out if any particular widget 
pointer is a button or not.

Thanks,

Roger
