Re: toggle button in TreeView not editable - appended with append_column_editable

[Christopher Lang <christopher lang acurana de>]

how lucky:

I just tried to put the line:

	sub1_treeview1->set_model (profile_tree_model);

right after the 

	Gtk::ListStore::create

and voila! It works, the bool is editable.

Obviously the model needs to be set *before* append_column_editable.

OK

thanks for your responses (got me thinking about my code again...)!
cheers
Chris
