bad coding?

[Richard Tew <RMT38 student canterbury ac nz>]

I am working on a program that brings up a window with two entry widgets
and when a button is pressed and its callback called, the contents of the
two widgets needs to be fetched and the window closed.

I have two questions I would appreciate answers for :)

1) The callback is called with the widget the signal was connected to
   (the button), to close the window I do:

   gtk_widget_destroy (GTK_WIDGET (button -> parent -> parent));

   (knowing that the button is in a table thats in a window)
   Is there a better way to close the window?

2) Before the window is destroyed/closed, I search through the list of
   widgets contained in the table and as I encounter a entry widget I nick
   its value.

   Is there a better way to get the values contained in entry widgets
   somewhere in the same table?

I know I could just allocate a structure and pass everything I might need
in callbacks, but I kind of like the way I can:

  gtk_signal_connect_object (button, "clicked",
                             GTK_SIGNAL_FUNC (gtk_widget_destroy),
                             window);

for when the cancel button in the table is pressed.

Anyway, any suggestions? :)
