commit 31f3eb1d57db73b895984a5c11c33899f07d00f7 Author: Katayama Hirofumi MZ <[email protected]> AuthorDate: Fri Apr 28 08:28:57 2023 +0900 Commit: GitHub <[email protected]> CommitDate: Fri Apr 28 08:28:57 2023 +0900 [RICHED20] RichEdit: CompForm and CandForm (#5257) Correctly display the composition window and the candidate window. - At update_caret function, set the position and font of the composition window. - We don't use internal composition string. Rely on the composition window. - Improve WM_IME_SETCONTEXT, WM_IME_CONTROL, WM_IME_SELECT, WM_IME_STARTCOMPOSITION, WM_IME_COMPOSITION and WM_IME_ENDCOMPOSITION message handlings.
