Glade produces the following XML code for gtknotebook in a ui file:
<child>
...
```
...
Then in the program we can load the glade ui file using gtk_builder_add_from_file
and then we can obtain the notebook by using gtk_builder_get_object on "My_Notebook".
I can't find how to obtain the child tab from the glade ui file.
I know that can obtain the page by using gtk_notebook_get_nth_page that returns a widget and then using it, for example, to hide the tab.
The question is: is it possible to obtain the tab page directly from the glade ui file?
