Why bother removing the widget in the first place. Do not add it in 
glade and ask for the parent, then construct and add it.

Perhaps you should ask on the libglade[mm] mailing list since this issue 
is only peripherally connected to glade--.

ogl_widget->show(); should be enough.

It should be possible to implement this code in glade-- if you want to 
take that road. In a way that glade-- emits a skeleton for your program 
(and takes care of the custom widgets). But this has not been done and 
perhaps it's even necessary to patch libglade to leave custom widgets 
alone to get this accomplished.

Perhaps libglade tries to call a C like creation function - try to 
provide this in your program (if libglade supports this).
