It would be convenient if GtkTextView could implement GtkEditable.

That would make it easier to implement signal handlers for Cut/Copy/Paste menu items, which currently need to special-case GtkTextView, as in the C++ example code from Glom below.

At the least, it would be nice to have gtk_tree_view_cut/copy/paste_clipboard() functions to avoid worrying about the clipboard, display, and selection each time.


void App_WithDoc_Gtk::on_menu_edit_paste_activate()
{
  Gtk::Widget* widget = get_focus();
  Gtk::Editable* editable = dynamic_cast<Gtk::Editable*>(widget);

  if(editable)
  {
    editable->paste_clipboard();
    return;
  }

  //GtkTextView does not implement GtkTextView:
  Gtk::TextView* textview = dynamic_cast<Gtk::TextView*>(widget);
  if(textview)
  {
    Glib::RefPtr<Gtk::TextBuffer> buffer = textview->get_buffer();
    if(buffer)
    {
      Glib::RefPtr<Gtk::Clipboard> clipboard = 
        Gtk::Clipboard::get_for_display(get_display());
      buffer->paste_clipboard(clipboard);
    }
  }
}
