Wanna catch a motion event

[Andreas Sliwka <goff nef wh uni-dortmund de>]

Hi,
  Id like to let the user pick out on of 18 specified rectangels in a pixmap.
So I display a window, put a GtkPixmap in it and connect a callback to the
motion_notify_event. But that did not work. So I created a event box, put the 
pixmap in it and connected the eventobox to the event. Now it works. As long 
as I press a mouse button. How can I accomplish it that my callback gets 
called even if no mouse button is pressed ?

  please have a look at the code snippet and show me where I´m wrong.

------------------- Code --------------------
	eventbox=gtk_event_box_new();
	small_bricks=gdk_pixmap_create_from_xpm (window->window, NULL,
	                                         &style->bg[GTK_STATE_NORMAL],
	                                         "small_bricks.xpm");
	small_bricks_widget=gtk_pixmap_new(small_bricks,NULL);
	gtk_container_add(GTK_CONTAINER(window),eventbox);
	gtk_container_add(GTK_CONTAINER(eventbox),small_bricks_widget);
	gtk_widget_show(small_bricks_widget);
	gtk_signal_connect(GTK_OBJECT(eventbox),"motion_notify_event",
	GTK_SIGNAL_FUNC(small_bricks_motion ),NULL);
	g_print("before\n");
	gtk_widget_set_events (eventbox, GDK_POINTER_MOTION_MASK
	                               | GDK_POINTER_MOTION_HINT_MASK);
	g_print("after\n");
------------------- Code --------------------
produces the following output:
  before

  Gtk-CRITICAL **: file gtkwidget.c: line 3827 (gtk_widget_set_events): assertion `!GTK_WIDGET_REALIZED (widget)' failed.
  after

What did I do wrong ?
