Re: interaction between widgets

[Harring Figueiredo <harringf yahoo com>]

 When you create your signal fucntion, you can pass a pointer to whatever
widget you want.
  Something like this:

 g_signal_connect(button_on_toolbar, button_callback_handler, "activate",
(gpointer) my_notebook);



  then one you callback handler, you have:

  button_callback_handler(GtkWidget* button_on_toolbar, gpointer data){
  /* the data passed in will be a pointer to "my_notebook" from above. */

  GtkNotebook*  book = (GtkNotebook*) data;

  Do whatever you want here wiht book.

}

  

  There is another way t pass the poiter -- you can connect an object to
another by using g_object_set_data(...) and then retrieve that pointer using
the g_object_get_data(...)
 Read the docs on this. (Which one is better ? it just depends on your taste.)

Hope this helps.
