   3  * Sample code from "GNOME/GTK+ Programming Bible" by Arthur Griffith
   4  * Modified by Kevin Gibbs (kgibbs@stanford.edu) to provide sample of
   5  * GtkMozEmbed realization/unrealization crashes.
   6  *
   7  * To get a fatal crash, simply run the program, click on the "Mozilla"
   8  * tab to display the MozEmbed widget, and then try to drag that MDI tab
   9  * off to a new window.
  10  *
  11  * Although this test might seem elaborate, it is really only a convenient
  12  * to create a situation where the widget is realized, unrealized, and
  13  * realized again at some point. (Dragging the MDI tab off to a new window
  14  * causes all widgets to be unrealized in the old window, and then realized
  15  * again in the new window.)

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

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