[PATCH 0/5] MR7812: win32u: Add more CompStrAttr, CompStrClause implementation using cursor_begin, cursor_end concept.
If CompStrAttr and CompStrClause are properly configured, Japanese input will be more comfortable. Inspired by cursor_begin and cursor_end from Wayland zwp_text_input_v3 preedit_string, I extended the cursor_pos concept as follows: cursor_pos = MAKELONG( cursor_begin, cursor_end ); ime_to_tascii_ex() uses this to construct CompStrAttr, CompStrClause. MS Windows native CompStrAttr, CompStrClause is a bit more complicated than this, but the concept is useful enough. It requires additional implementation in the Wine ime_ui_window proc and richedit control. However, it is useful for applications that inline ime composition string. This can be tested with MS Office Word, Excel. LANG=ja_JP.UTF-8 wine EXCEL.EXE Test key sequences: - “n-i-h-o-n-g-o-n-o-m-o-j-i-d-e-s-u-.-SPACE”. - And, RIGHT, LEFT, Shift+LEFT, Shift+RIGHT, SPACE, UP, DOWN, ESC, etc. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7812
