From 22fa45b3c1392c16f52b49ef01caa19cfa9731e7 Mon Sep 17 00:00:00 2001 From: Frank Praznik Date: Thu, 5 Jun 2025 12:14:54 -0400 Subject: [PATCH] win32: Ensure that text input is initially disabled when creating a window Windows seems to implicitly enable IME text input on windows created while an IME is active, which causes the IME suggestion window to pop up when keys are pressed, even if a client never explicitly enabled it. Ensure that IME support is initially disabled on new windows; SDL will enable it at a later time, if required. --- src/video/windows/SDL_windowswindow.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/src/video/windows/SDL_windowswindow.c b/src/video/windows/SDL_windowswindow.c index f61dc0e8f8..de27882901 100644 --- a/src/video/windows/SDL_windowswindow.c +++ b/src/video/windows/SDL_windowswindow.c @@ -33,6 +33,7 @@ #include "../SDL_sysvideo.h" #include "SDL_windowsvideo.h" +#include "SDL_windowskeyboard.h" #include "SDL_windowswindow.h" // Dropfile support @@ -780,6 +781,9 @@ bool WIN_CreateWindow(SDL_VideoDevice *_this, SDL_Window *window, SDL_Properties return false; } + // Ensure that the IME isn't active on the new window until explicitly requested. + WIN_StopTextInput(_this, window); + // Inform Windows of the frame change so we can respond to WM_NCCALCSIZE SetWindowPos(hwnd, NULL, 0, 0, 0, 0, SWP_FRAMECHANGED | SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | SWP_NOOWNERZORDER | SWP_NOACTIVATE);
