TextServerManager

继承： Object

A singleton for managing TextServer implementations.

描述

TextServerManager is the API backend for loading, enumerating, and switching 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.
