# wx.TopLevelWindow.GeometrySerializer¶

Class used with SaveGeometry and RestoreToGeometry.

This is an abstract base class, i.e. to use it you must define a derived class implementing the pure virtual SaveField and RestoreField methods.

For example, if you wished to store the window geometry in a database, you could derive a class saving fields such as “width” or “height” in a table in this database and restoring them from it later.

New in version 4.1/wxWidgets-3.1.2.
