Button events not workingHi,
I am new hand of GTK programming. But I think maybe you should connect those events to a button not a window.

  Given following code: 

  #include <gtk/gtk.h> 

  gboolean 
  button_press_event(GtkWidget *widget, GdkEventButton *event, gpointer data) 
  { 
    g_print("button-press-event\n"); 
    return FALSE; 
  } 

  gboolean 
  button_release_event(GtkWidget *widget, GdkEventButton *event, gpointer data) 
  { 
    g_print("button-release-event\n"); 
    return FALSE; 
  } 

  gboolean 
  key_press_event(GtkWidget *widget, GdkEventKey *event, gpointer data) 
  { 
    g_print("key-press-event\n"); 
    return FALSE; 
  } 

  gboolean 
  key_release_event(GtkWidget *widget, GdkEventKey *event, gpointer data) 
  { 
    g_print("key-release-event\n"); 
    return FALSE; 
  } 

  gboolean 
  delete_event(GtkWidget *widget, GdkEvent *event, gpointer data) 
  { 
    gtk_widget_destroy(widget); 
    gtk_main_quit(); 
    return FALSE; 
  } 

  int main(int argc, char* argv[]) 
  { 
    GtkWidget *window; 

    gtk_set_locale (); 
    gtk_init (&argc, &argv); 

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL); 

    gtk_signal_connect(GTK_OBJECT(window), "delete-event", GTK_SIGNAL_FUNC(delete_event), NULL); 
    gtk_signal_connect(GTK_OBJECT(window), "button-press-event", GTK_SIGNAL_FUNC(button_press_event), NULL); 
    gtk_signal_connect(GTK_OBJECT(window), "button-release-event", GTK_SIGNAL_FUNC(button_release_event), NULL); 
    gtk_signal_connect(GTK_OBJECT(window), "key-press-event", GTK_SIGNAL_FUNC(key_press_event), NULL); 
    gtk_signal_connect(GTK_OBJECT(window), "key-release-event", GTK_SIGNAL_FUNC(key_release_event), NULL); 

    gtk_widget_show(window); 

    gtk_main (); 

    return 0; 
  } 

  I tested this program under RH Linux 7.0 and under Windows 2000 with the gtk port to win32 and it behaves exactly the same.

  - Both button-press-event and button-release-event are not responding at all when clicking over the window. 
  - key-release-event is not responding either. 
  - When I press a key without releasing it, the window starts calling key_press_event(...) many, many times. 

  I supposed that the key-press-event would be emitted only once when I press a key so, when I release it the key-release-event is emitted.

  Is there a problem connecting these events with toplevel windows? 
  Is this the correct behavior?
