Re: Get row text from a treeview

[Martyn Russell <ginxd btopenworld com>]

This is how I did it....

gboolean
on_treeview_roster_button_press_event  (GtkWidget       *widget,
                                        GdkEventButton  *event,
                                        gpointer         user_data)
{
  /* Note: Can also use GDK_BUTTON_PRESS, 
   * GDK_2BUTTON_PRESS, GDK_3BUTTON_PRESS
   */
  if(event->type == GDK_2BUTTON_PRESS)
    {
      GtkTreeSelection *selection;
      GtkTreeModel *model;
      GtkTreeIter iter;

      gchar *text = NULL;

      g_print("**** got double click event\n");

      selection = gtk_tree_view_get_selection(GTK_TREE_VIEW(widget));
      gtk_tree_selection_set_mode(selection,GTK_SELECTION_SINGLE);
      gtk_tree_selection_get_selected(selection,&model,&iter);
  
      gtk_tree_model_get(model, &iter, 
                         COLUMN_NUMBER, &text,
                         -1);      

      g_print("**** text is '%s'",text);

      if(text != NULL)
        g_free(text);
    }

  return FALSE;
}

BUT - the one thing I did find, is that get selection doesn't work with
GTK_SELECTION_MULTIPLE (i think).  That is why I changed the selection
here...(gtk_tree_selection_set_mode).  I suppose you could set that up
with the GtkTreeView at the start of your application. 

Plus, in case you're wandering... the 'model' is only for the users'
convenience, see the api page:

http://developer.gnome.org/doc/API/2.0/gtk/gtktreeselection.html#gtk-tree-selection-get-selected
