I've done that. However, I then lose the ability to edit the glade file
with Gazpacho, as it will a) not show my widget, and b) remove it when I
save the file.

It's derived from the GtkDrawingArea - it will be an oscilloscope display.

Well, the problem is that I didn't see any other way to get a hold of a
widget at something like construction time, given that I am using
libglade.

However, I am hooking the events during the construction of the widgets,
by using glade_xml_signal_autoconnect_full with my own handler function,
so I would think this would allow the events to be hooked as the widget is
constructed but before it is realized - is that not the case?

BTW: I had been directed to try asking questions in IRC, but when I went
there things seemed pretty dead - either that or I wasn't doing something
wrong (this is my first time using IRC).
