which way is better?

[Aaron Walker <amwalker gate net>]

Hello,

I am kind of new to GTK+ programming, so please bear with me.  Would it
be better to use global variables for Gtk widgets, and have all
functions in that file use them, or create separate widgets for each
function?

Here is an example bit of code:

<start>
#include <gtk/gtk.h>

/* globals */
GtkWidget *window;
GtkWidget *button;

void exfunc(void)
{
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    button = gtk_button_new_with_label("Button");
    gtk_widget_show(button);
    gtk_widget_show(window);
}

int main(int argc, char *argv[])
{
    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    button = gtk_button_new_with_label("Button");
    gtk_widget_show(button);
    gtk_widget_show(window);

    gtk_main();
    return 0;
}
</stop>

By defining those widgets as globals, do I reduce the amount of memory
used by the program?
What is everyone else's opinion on this?

Thanks,
Aaron
