Re: Passing data from a data collection window back to a main

["ksadil bigpond net au" <ksadil bigpond net au>]

This is my global variable version:

   #include <gtk/gtk.h>

   #include "callbacks.h"
   #include "interface.h"
   #include "support.h"

   GtkWidget *window2, *window1, *label1, *entry1;

   void
   on_button1_clicked                     (GtkButton       *button,
                                        gpointer         user_data)
   {
    window1 = lookup_widget(button,"window1");
    window2=create_window2();
    gtk_widget_show(window2);
    gtk_grab_add(window2);
   }


   void
   on_button2_clicked                     (GtkButton       *button,
                                           gpointer         user_data)
   {
    label1 = lookup_widget(window1,"label1");
    entry1 = lookup_widget(window2,"entry1"); 
    gtk_label_set_text(label1,gtk_entry_get_text(entry1));
    gtk_grab_remove(window1);
    gtk_widget_destroy(window2);
   }

Thanks,
Kim
