 120 This class allows you to use the system font selection dialog
 121 from within your program. Generally speaking, this allows you
 122 to select a font by its name, font size, and weight, and
 123 on some systems such things as strikethrough and underline.
 124
 125 As with other dialogs used in wxPython, it is important to
 126 use the class' methods to extract the information you need
 127 about the font <b>before</b> you destroy the dialog. Failure
 128 to observe this almost always leads to a program failure of
 129 some sort, often ugly.
 130
 131 This demo serves two purposes; it shows how to use the dialog
 132 to GET font information from the user, but also shows how
 133 to APPLY that information once you get it.
