"The GtkTreeModel <https://developer.gnome.org/gtk3/stable/GtkTreeModel.html> interface defines a generic tree interface for use by the GtkTreeView <https://developer.gnome.org/gtk3/stable/GtkTreeView.html> widget. It is an abstract interface, and is designed to be usable with any appropriate data structure. The programmer just has to implement this interface on their own data type for it to be viewable by a GtkTreeView <https://developer.gnome.org/gtk3/stable/GtkTreeView.html> widget." for *bunches of those data, each in a different tab inside the same window.* On Mon, Mar 19, 2018 at 8:13 PM, Bachsau <w...@bachsau.name> wrote: > Am 19.03.2018 um 13:21 schrieb Lucky B.C: > >> don't keep only one GtkTreeModel for storing the data, I mean you should >> have multiple GtkTreeModels. >> > > You mean I should use more than one GtkTreeModel for a *single* set of > data?
