After watching this video: http://developer.ubuntu.com/get-started/
I've created an Ubuntu application using Quickly and Glade. However, after adding a tab control (called a Notebook in glade), I hit the save button in Glade.
When I try to run my application (by typing "quickly run") at the command prompt, I get his error:
Gtk:ERROR:/build/buildd/gtk+3.0-3.6.4/./gtk/gtknotebook.c:1235:gtk_notebook_buildable_add_child: assertion failed: (page != NULL)
If I delete that same notebook control in Glade, save, and run. I get no error.
I'm not sure what to do next. Please advise.
I found my answer here.
You must put another control into the notebook control before it will build at all.
