Hi,
I understand that one can implement custom TreeModels (to replace
Gtk::ListStore and Gtk::TreeStore). Can this be done by deriving
from Gtk::TreeModel? Do you have a tutorial on this subject.
What would be the skeleton of such a derived class?
class myModel : public ?Gtk::TreeModel{?
public:
Gtk::TreeModelFlags? get_flags_vfunc () const;
//.... and other vfuncs
};
Thanks for any hints.

Jens
Maybe, this example can help you:
https://git.devuan.org/aitor_czr/simple-netaid-gtk/tree/master/
Have a look at the treeview.cpp and the col_model.cpp
You can find another example in the gtkmm tutorial:
https://developer.gnome.org/gtkmm-tutorial/stable/sec-treeview-examples.html.en
BTW, it'll not build succesfully in debian or devuan jessie (or
derivatives) due to the version of g++, getting the following errors:
[...]
simple-netaid-gtk/include/passwd_dialog.h:32:8: error: ?thread? in
namespace ?std? does not name a type
?? std::thread *m_WorkerThread;
window_main_worker.h:44:16: error: ?mutex? in namespace ?std? does not
