Re: Page numbers in GtkNotebook

["Audrey Vernon" <audrey vernon colorado edu>]

The page number depends on its location in the graph notebook I believe, so
if you delete tabs before it the number will change.  This works fine for
things like removing:

  gint page;
  page = gtk_notebook_get_current_page (myGraphData->notebook);
  gtk_notebook_remove_page (myGraphData->notebook, page);


But what I did when I needed a specific tab was the following:

  // Get the current notebook tab
  int currentPageIndex = gtk_notebook_get_current_page(myData->notebook);
  GtkFrame *currentPage = GTK_FRAME(gtk_notebook_get_nth_page
                                          (myData->notebook,
                                           currentPageIndex));

Then you can get the notebook label or the widget name or something else to
uniquely identify which tab is actually open.

I'm not sure if this is ideal, but it worked for me.
