display

hi everyone,

 

as gtk is event driven, does anyone know how i can create a program that can send "clicked" signals on its own without user input?

 

e.g.

 

void push_item( GtkWidget *widget,
                gpointer   data )
{
  static int count = 1;
  char buff[20];

  sprintf (buff, "Item %d", count++);
  gtk_statusbar_push (GTK_STATUSBAR (status_bar), GPOINTER_TO_INT (data),               buff);

  return;
}

int main (int argc, char *argv[])
{
...
    context_id = gtk_statusbar_get_context_id(
                          GTK_STATUSBAR (status_bar), "Statusbar example");

    button = gtk_button_new_with_label ("push item");
    g_signal_connect (G_OBJECT (button), "clicked",
                      G_CALLBACK (push_item), GINT_TO_POINTER (context_id));
    gtk_box_pack_start (GTK_BOX (vbox), button, TRUE, TRUE, 2);
    gtk_widget_show (button);             
    gtk_widget_show (window);

    gtk_main ();

    return 0;
}

push_item is a function that displays item %d, which increases each time "clicked" signal is sent from the main function.

  so how do i code this so that the user need not click the mouse, but a "clicked" signal is sent?

thanks
