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
