gtk 3 GtkBuilder, GtkEntryCompletion, How do I get this tree for the completion data?

Question

I've been scouring every documentation source I can find, checking source examples, but I still have no idea how to use the GtkEntryCompletion for my GtkEntry.

know how to do it manually, without glade, source examples are abundant, but they are only applicable once I get the tree object.

    g_slice_free(struct widgets, widgets);

    return EXIT_SUCCESS;
}

I believe I'm supposed to get liststore1, and then I can populate it, but all the ways I tried I was failing GTK's assertions.

I figured it out in my github repository,

https://github.com/techzilla/gtk3run.git

Turns out you just gtk_builder_get_object the liststore.
