This feature can be enabled by -feature-wayland-text-input-v4-wip.
It is disabled by default.
TextInputManagerV4 is available in a compositor.
zwp_text_input_v4 is available for QT_WAYLAND_TEXT_INPUT_PROTOCOL in
a client
It supports Hangul(Korean) with a qtvirtualkeyboard patchset
(refs/changes/02/357902/3)
It includes some workarounds for ibus because each ibus module has its own
policy for focus-in/focus-out.
enter/leave will synchronize with enable/disable and they will happen
whenever focus-in/focus-out happen.
Cursor/anchor positions are byte offsets.
Surrounding text will be trimmed when it is over 4000 byte.
For debugging,
uses "qt.waylandcompositor.textinput" in a compositor side
uses "qt.qpa.wayland.textinput" in a client side
Tested on qtvirtualkeyboard and ibus
TODO :
* QTBUG-97248 - event:preedit_commit_mode is not implemented yet. Current
