TextServerManager
=================

**Inherits:** :ref:`Object<class_Object>`

A singleton for managing :ref:`TextServer<class_TextServer>` implementations.

.. rst-class:: classref-introduction-group

Description
-----------

**TextServerManager** is the API backend for loading, enumerating, and switching :ref:`TextServer<class_TextServer>`\ s.

\ **Note:** Switching text server at runtime is possible, but will invalidate all fonts and text buffers. Make sure to unload all controls, fonts, and themes before doing so.
