Re: Notebooks in Gtk+ v1.2.x

[Jim Parker <hopeye cfl rr com>]

Well I have used that method when using other notebook dialogs, but for 
this situation the only widget on the page is the drawing widget.

That also was the first method I tried, calling the widgets 
draw_area_1, etc.  Unfortunately it did not work.  I am pretty 
convinced I need seperate rotation/zoom variables for each drawing 
area.  Hence my linked list idea.

thanks for the idea.

cheers,
Jim Parker
