how to set custom icon theme?

[gnome hupe me]

Hi everyone,

I would like to set the icon theme in my application.

I added in main.cc the following but this has no effect:
  Glib::RefPtr<Gtk::IconTheme> defaultIconTheme = Gtk::IconTheme::create();
  defaultIconTheme->set_custom_theme("Gartoon");

What is the correct way to do it?

Thank you in advance.

Best,

Phil


I use gtkmm-3.0 3.4.0 under debian wheezy.

compilation command:
g++  -c `pkg-config gtkmm-3.0 --cflags --libs` *.cc
g++  `pkg-config gtkmm-3.0 --cflags --libs` *.o
