drawing area and event order

[Alexander Nagel <feuerschwanz76 web de>]

Hi everybody,
i have a drawing area in my application and conncted following signals
"realize", "unrealize", "configure_event" and "expose_event".
And it works...

The code:
Widgets_MainWindow.drawingarea1 = gtk_drawing_area_new ();

GTK_WIDGET_SET_FLAGS (GTK_WIDGET (Widgets_MainWindow.drawingarea1),
GTK_CAN_FOCUS); 

gtk_widget_show (Widgets_MainWindow.drawingarea1);

gtk_widget_add_events (Widgets_MainWindow.drawingarea1,
GDK_BUTTON_PRESS_MASK | GDK_BUTTON_RELEASE_MASK | GDK_BUTTON_MOTION_MASK);

gtk_table_attach
(GTK_TABLE(Widgets_MainWindow.table1),Widgets_MainWindow.drawingarea1, 1,
2, 1, 2,(GtkAttachOptions)(GTK_EXPAND | GTK_FILL), (GtkAttachOptions)
(GTK_EXPAND | GTK_FILL), 5,5);

The events are properly connected, that works for sure.

I thought the "realize" event is the first event raised, but it isn't. The
first one is "configure_event". And it doesn't matter in which order the
code is. 

I want to ini a class in the "realize" event.

I just tried 
gtk_widget_realize (Widgets_MainWindow.drawingarea1);

before the 
gtk_widget_show (Widgets_MainWindow.drawingarea1);

but then no "realize" event occurs.

Why is that??
And which event is really the first one?

Any help is much appreciated

Alex
