From bfbda74851ae4de3b0b185862af566005b477930 Mon Sep 17 00:00:00 2001 From: Felix Yan Date: Tue, 23 Sep 2014 23:22:17 +0800 Subject: winex11.drv: Update a candidate window's position with over-the-spot style. (try 2) In the current implementation, the candidate window position of a input method is fixed because XNSpotLocation isn't updated after an input context (XIC) is created in X11DRV_CreateIC(). X11DRV_UpdateCandidatePos() in this patch updates the position. You can see the change of a position with ibus, scim or fcitx when input style is set to "over the spot" in the registry key: [HKEY_CURRENT_USER\Software\Wine\X11 Driver] "InputStyle"="OverTheSpot" This patch was based on the original work by Muneyuki Noguchi, and received a lot of help from Sebastian Lackner. --- dlls/user32/caret.c | 4 +++ dlls/user32/driver.c | 14 ++++++++ dlls/user32/user_private.h | 2 ++ dlls/winex11.drv/winex11.drv.spec | 1 + dlls/winex11.drv/xim.c | 72 ++++++++++++++++++++++++++++++++++++++- 5 files changed, 92 insertions(+), 1 deletion(-) diff --git a/dlls/user32/caret.c b/dlls/user32/caret.c index 686dade..d1cde7f 100644 --- a/dlls/user32/caret.c +++ b/dlls/user32/caret.c @@ -30,6 +30,8 @@ #include "winbase.h" #include "wingdi.h" #include "winuser.h" +#include "user_private.h" + #include "wine/server.h" #include "wine/debug.h" @@ -277,6 +279,7 @@ BOOL WINAPI SetCaretPos( INT x, INT y ) r.left = x;
