161\membersection{wxFont::\destruct{wxFont}}
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.
