162
163\func{}{\destruct{wxFont}}{\void}
164
165Destructor.
166
167\wxheading{Remarks}
168
169The destructor may not delete the underlying font object of the native windowing
775a998e 170system, since wxFont uses a reference counting system for efficiency.
a660d684
KB
171
172Although all remaining fonts are deleted when the application exits,
173the application should try to clean up all fonts itself. This is because
174wxWindows cannot know if a pointer to the font object is stored in an
175application data structure, and there is a risk of double deletion.

282To avoid portability problems, don't rely on a specific face, but specify the font family
283instead or as well. A suitable font will be found on the end-user's system. If both the
284family and the facename are specified, wxWindows will first search for the specific face,
285and then for a font belonging to the same family.
