\destruct{wxFont
}}
163 \func{}{\destruct{wxFont
}}{\void}
169 The destructor may not delete the underlying font object of the native windowing
170 system, since wxFont uses a reference counting system for efficiency.
172 Although all remaining fonts are deleted when the application exits,
173 the application should try to clean up all fonts itself. This is because
174 wxWindows cannot know if a pointer to the font object is stored in an
175 application data structure, and there is a risk of double deletion.

300 instead or as well. A suitable font will be found on the end-user's system. If both the

302 and then for a font belonging to the same family.
