/** simplemdi.c **/
/*
 * Sample code from "GNOME/GTK+ Programming Bible" by Arthur Griffith
 * Modified by Kevin Gibbs (kgibbs@stanford.edu) to provide sample of
 * GtkMozEmbed realization/unrealization crashes.
 *
 * To get a fatal crash, simply run the program, click on the "Mozilla"
 * tab to display the MozEmbed widget, and then try to drag that MDI tab
 * off to a new window.
 * 
 * Although this test might seem elaborate, it is really only a convenient
 * to create a situation where the widget is realized, unrealized, and
 * realized again at some point. (Dragging the MDI tab off to a new window
 * causes all widgets to be unrealized in the old window, and then realized
 * again in the new window.)

// Testing flags
//

// Define this flag to have the test program use the gtkmozembed widget.
// Without this flag, mozilla is never loaded in the program, and a simple
// widget is used in place of the mozembed widget.
#define USE_MOZILLA_TEST

// Define this flag to have a simpler test than the usual one. The normal
// test builds a notebook inside of each MDI view, with one page being a label
// and the other page being a browser widget. The simpler test does not
// build a notebook and simply puts the browser widget in the MDI view itself.
// Currently, this test is not very interesting, since for some reason all
// the webshells just create and destroy themselves. (???)
//#define SIMPLER_TEST

// Define this flag to use a GnomePixmap instead of a GtkLabel as the
// replacement for the gtkmozembed widget when USE_MOZILLA_TEST is
// undefined. This is to stress test the program a bit more by providing a
// replacement widget slightly more complex than GtkLabel.
// (Has no effect when USE_MOZILLA_TEST is defined.)
