Adds support for text input and input 30 methods to applications. A text_input object is created from a 31 wl_text_input_manager and corresponds typically to a text entry in an 32 application. 33 34 Requests are used to activate/deactivate the text_input object and set 35 state information like surrounding and selected text or the content type. 36 The information about entered text is sent to the text_input object via 37 the pre-edit and commit events. Using this interface removes the need 38 for applications to directly process hardware key events and compose text 39 out of them. 40 41 Text is generally UTF-8 encoded, indices and lengths are in bytes. 42 43 Serials are used to synchronize the state between the text input and 44 an input method. New serials are sent by the text input in the 45 commit_state request and are used by the input method to indicate 46 the known text input state in events like preedit_string, commit_string, 47 and keysym. The text input can then ignore events from the input method 48 which are based on an outdated state (for example after a reset). 49 50 Warning! The protocol described in this file is experimental and 51 backward incompatible changes may be made. Backward compatible changes 52 may be added together with the corresponding interface version bump. 53 Backward incompatible changes are done by bumping the version number in 54 the protocol and interface names and resetting the interface version. 55 Once the protocol is to be declared stable, the 'z' prefix and the 56 version number in the protocol and interface names are removed and the 57 interface version number is reset. 58 </description> 59 60 <request name="activate"> 61 <description summary="request activation"> 62 Requests the text_input object to be activated (typically when the 63 text entry gets focus). 64 65 The seat argument is a wl_seat which maintains the focus for this 66 activation.
