Hello Jose,
if you want to pass multiple parameters you should put them into a
structure, like:
struct {
  char *szFilename;
  GtkWidget *pWidget;
} UserData;

You can pass a pointer to this structure into g_timeout_add(). Inside the
callback you can access the single elements of your structure by the given
pointer.

Regards,
                 Peter
