[Glade-users] signals

Hi,

When you have to pass more than one argument, pass a structure pointer and 
cast is to gpointer.
here's an example:
http://www.gnome.org/~newren/tutorials/developing-with-gnome/html/apcs04.html

Same goes to pass an array. Then cast it in the callback function.


static void callback(GtkWidget *widget, gpointer data)
{
  g_print ("%s was passed\n", (char *) data);
}

...

 button = gtk_button_new ();
 g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK (callback), 
(gpointer) "This is a char array");
