Clean up the code of many examples in minor ways, fix some memory leaks, and avoid the use of dialogs where a regular toplevel works just as well.

/* CSS Theming/Style Classes
|
|
*
|
|
* GTK+ uses CSS for theming. Style classes can be associated
|
|
* with widgets to inform the theme about intended rendering.
|
|
*
|
|
* This demo shows some common examples where theming features
|
|
* of GTK+ are used for certain effects: primary toolbars,
|
|
* inline toolbars and linked buttons.
