 235     @class wxFont
 236
 237     A font is an object which determines the appearance of text.
 238     Fonts are used for drawing text to a device context, and setting the appearance
 239     of a window's text.
 240
 241     This class uses @ref overview_refcount "reference counting and copy-on-write"
 242     internally so that assignments between two instances of this class are very
 243     cheap. You can therefore use actual objects instead of pointers without
 244     efficiency problems. If an instance of this class is changed it will create
 245     its own data internally so that other instances, which previously shared the
 246     data using the reference counting, are not affected.
 247
 248     You can retrieve the current system font settings with wxSystemSettings.
