Corresponds to a text model on input method side. An input method context is created on text mode activation on the input method side. It allows to receive information about the text model from the application via events. Input method contexts do not keep state after deactivation and should be destroyed after deactivation is handled. Send the commit string text to the applications text model. Send the pre-edit string text to the applications text model. Notify when a key event was sent. Key events should not be used for normal text input operations, which should be done with commit_string, delete_surrounfing_text, etc. The key event follows the wl_keyboard key event convention. State is a XKB keysym, state a wl_keyboard key_state. Allows an input method to receive hardware keyboard input and process key events to generate text events (with pre-edit) over the. This allows input methods which compose multiple key events for inputting text like it is done for CJK languages. The plain surrounding text around the input position. Cursor is the position within the surrounding text. Anchor is the position of the selection anchor within the surrounding text. If there is no selected text anchor is the same as cursor. An input method object is responsible to compose text in response to input from hardware or virtual keyboards. There is one input method object per seat. On activate there is a new input method context object created which allows the input method to communicate with the text model. A text model was activated. Creates an input method context object which allows communication with the text model. The text model corresponding to the context argument was deactivated. The input method context should be destroyed after deactivation is handled.
