Re: treeview Tab control

["Thomas Sommer" <mawa15 gmx de>]

Totally correct,

problem is: I just don't know how to get the value in the editable.
That's what I tried:

bool ExampleWindow::on_key_press(GdkEventKey* event)
   {
      std::cout << event->keyval << "\n";
      Gtk::CellRenderer* r=m_TreeView.get_column_cell_renderer (1);
      Gtk::CellRendererText* cr=dynamic_cast<Gtk::CellRendererText*>(r);
      std::cout << cr->gobj()->text << "\n";
   }

I only get the "old" value stored in the treeview. Not the one in the editable.
