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