GtkEntryCompletion and GtkComboBox only show top level nodes when using GtkTreeModelFilter
The title says it all. Comboboxes and Entrycompletions only show the top level nodes when using GtkTreeModelFilter models. Specifically, this keeps one from using Completions on a TreeStore. This question came up on StackOverflow here.
I have hooked into the completion.set_match_func() and all child nodes are traveled properly for matching, but not displayed. I then went to subclass a GtkCellRendererText, and quickly discovered that the GtkTreeModelFilter is the problem.
I willl post all new findings here.
