IME_INTERNAL_EDITING

A hint that specifies whether certain IMEs should handle text editing internally instead of sending SDL_TEXTEDITING events.

The variable can be set to the following values:

• "0" - SDL_TEXTEDITING events are sent, and it is the application's

  responsibility to render the text from these events and

  differentiate it somehow from committed text. (default)

• "1" - If supported by the IME then SDL_TEXTEDITING events are

  not sent, and text that is being composed will be rendered

  in its own UI.

By default SDL_TEXTEDITING events are sent, and it is the application's responsibility to render the text from these events and differentiate it somehow from committed text.
