[Glade-users] is there an example or tutorial about the use of 'GtkTreeStore' in the Glade?

I dont know if I understand what you are asking.

What could you possibly mean by "VISIBLE by now" ??

Let me be clear.

If you need to use a GtkTreeStore, you can define the column types
in Glade... you CANNOT add any data to it.

ANYTHING you add to the GtkTreeStore must be done with code.

This is all greek to me, I have no idea what any of this means.
