5.9. How do I catch a double click event? [GTK 2.x]

Tim Janik wrote to gtk-list (slightly modified):

Define a signal handler:

gint
signal_handler_event(GtkWidget *widget, GdkEventButton *event, gpointer func_data)
{
  if (GTK_IS_BUTTON(widget) &&
       (event->type==GDK_2BUTTON_PRESS ||
        event->type==GDK_3BUTTON_PRESS) ) {
    printf("I feel %s clicked with button %d\n",
           event->type==GDK_2BUTTON_PRESS ? "double" : "triple",
           event->button);
  }

  return FALSE;
}

And connect the handler to your object:

{
  /* button init stuff */     

  g_signal_connect(G_OBJECT(button),
                     "button_press_event",
                     G_CALLBACK(signal_handler_event),
                     NULL);

  /* and/or */

  g_signal_connect(G_OBJECT(button),
                     "button_release_event",
                     G_CALLBACK(signal_handler_event),
                     NULL);

  /* something else */
}

"Note that a single button press will be received beforehand, and if you are doing this for a button, you will therefore also get a "clicked" signal for the button. (This is going to be true for any toolkit, since computers aren't good at reading one's mind.)"
