[Freeciv-Dev] GTK gurus: one question

[Tuomas Airaksinen <tuma@xxxxxxxxxxxx>]

I need to show map_canvas widget on two pages of my notebook: 
firstly in "City" and secondly in "Happiness" page. So - I just tried
to gtk_container_add(GTK_CONTAINER(frame), pdialog->map_canvas) 
another time - frame is show, but map_canvas is not. Only following 
gtk error appears:

Gtk-CRITICAL **: file gtkcontainer.c: line 715 (gtk_container_add):
assertion `widget->parent == NULL' failed.

What do I need to "duplicate" widget, or do I need to make all things
twise (create a new array and so on) to show it in second place?
