Re: array of widgets...

[Mihai Bazon <mbazon websci ro>]

The problem is simple: the entry array is a local variable (local to
function) and it gets destroyed when you exit the function.

Better try this way:

  GtkWidget **entry;
  entry = (GtkEntry**)malloc(sizeof(GtkEntry*) * 3);

  ...

  /* pass it to the signal handler.. */
  gtk_signal_connect(GTK_OBJECT(button), "clicked",
                     GTK_SIGNAL_FUNC(your_func), entry);
  ...
} /* function ends here, the entry pointer is lost, but memory remains
   * alloc-ed, so you don't receive an invalid pointer in your signal
   * handler */

Remember to free() this memory at one point when you don't need it
anymore.
