From 6856c5249104d2b69fe297ff7546092e3bb23555 Mon Sep 17 00:00:00 2001 From: Andreas Haas Date: Fri, 1 Jul 2016 15:31:37 +0200 Subject: [PATCH] Windows: prevent freeze while moving or resizing the game window. When moving or resizing the window, Windows spins up a seperate event-loop, effectively blocking the normal one. To work around this, we're starting a timer that will continue sending WM_TIMER messages which we can use to keep the mainloop running. fixes #4695 --- platform/windows/os_windows.cpp | 16 +++++++++++++++- platform/windows/os_windows.h | 2 ++ 2 files changed, 17 insertions(+), 1 deletion(-) diff --git a/platform/windows/os_windows.cpp b/platform/windows/os_windows.cpp index 9421e0d48e3..89de969cff4 100644 --- a/platform/windows/os_windows.cpp +++ b/platform/windows/os_windows.cpp @@ -612,6 +612,20 @@ LRESULT OS_Windows::WndProc(HWND hWnd,UINT uMsg, WPARAM wParam, LPARAM lParam) { } //return 0; // Jump Back } break; + + case WM_ENTERSIZEMOVE: { + move_timer_id = SetTimer(hWnd, 1, USER_TIMER_MINIMUM,(TIMERPROC) NULL); + } break; + case WM_EXITSIZEMOVE: { + KillTimer(hWnd, move_timer_id); + } break; + case WM_TIMER: { + if (wParam == move_timer_id) { + process_key_events(); + Main::iteration(); + } + } break; + case WM_SYSKEYDOWN: case WM_SYSKEYUP: case WM_KEYUP: @@ -1140,7 +1154,7 @@ void OS_Windows::initialize(const VideoMode& p_desired,int p_video_driver,int p_ DragAcceptFiles(hWnd,true); - + move_timer_id = 1; } void OS_Windows::set_clipboard(const String& p_text) { diff --git a/platform/windows/os_windows.h b/platform/windows/os_windows.h index 509d76abbf1..d2249bf3524 100644 --- a/platform/windows/os_windows.h +++ b/platform/windows/os_windows.h @@ -104,6 +104,8 @@ class OS_Windows : public OS { HINSTANCE hInstance; // Holds The Instance Of The Application HWND hWnd; + uint32_t move_timer_id; + HCURSOR hCursor; Size2 window_rect;
