Re: Trying to add a page to a notebook

[frederico schardong <frede sch gmail com>]

Yes, a invisible page are added every time.

Adding this, it works:

gtk_widget_show_all(vbox);
gtk_notebook_remove_page(GTK_NOTEBOOK(notebook), 0);
gtk_notebook_insert_page(GTK_NOTEBOOK(notebook), vbox, label, 0);

Thanks everyone.
