Well that was simple. Thanks for the help. I had added the hbox prior to a call to show_all_children() for the main window, and I didn't realize I'd have to call show_all() separately.

The hbox contains a label and a button, but when I use append_page(Widget& child, Widget& tab_label), the tab appears very small and empty. If I insert either the label or the button alone, they appear, but not when placed in an hbox. Are there any caveats pertaining to what can be included in a notebook tab, or is there something else I should be looking for?Are the label and the button shown? E.g. hbox->show_all (). Paul |
