public abstract class InputMethodContext : Object

Base class for input method contexts.

WebKitInputMethodContext defines the interface to implement WebKit input methods. The input methods are used by WebKit, when editable content is focused, to map from key events to Unicode character strings.

An input method may consume multiple key events in sequence and finally output the composed result. This is called preediting, and an input method may provide feedback about this process by displaying the intermediate composition states as preedit text.
