Hi Jens,

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.

Regards

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 name a type
   mutable std::mutex m_Mutex;
[...]

HTH,

  Aitor.
