/*
|
|
* 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.)

// 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.
