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