Here is the offending code in red:

  //Child widgets:
  Gtk::VBox m_VBox;
  Gtk::HBox m_HBox;
  Gtk::ComboBox m_ComboOrientation;
  Glib::RefPtr<Gtk::ListStore> m_refTreeModelOrientation;
  Gtk::ComboBox m_ComboStyle;
  Glib::RefPtr<Gtk::ListStore> m_refTreeModelStyle;
  Gtk::ToolPalette m_ToolPalette;
  Gtk::ScrolledWindow m_ScrolledWindowPalette;
  Gtk::ScrolledWindow m_ScrolledWindowCanvas;

Hi All,

I am working on a project that has a treeview of items. The tree items can
be draged and dropped from one place to another. I got the tree view work by
following the examples.

Now I got one question:
In the process of drag&drop, I also want to operate on data structure
represented by the tree view. For example when one item is dragged and
dropped to another item, I want to remove the link to it from its old place
and add the link to its dropped place in a data structure behind the
treeview. How do I do this? What is the function to use? If you could point
me to some example that would be great.

Thank you very much!

Chun
