Sam Lantinga b9cbea35 2020-10-13T21:08:20 video: Refresh Windows display list on WM_DISPLAYCHANGE - Displays may have been added, removed or changed and all cached monitor handles are invalidated as a result. - Display events are handled in three steps: 1. Mark all currently know displays as invalid 2. Enumerate all displays, adding new ones and marking known displays as valid 3. Remove all displays still invalid after enumeration - Display connect/disconnect events are sent when displays are added or removed after initial setup
Sam Lantinga 76980e30 2020-10-08T16:42:20 Added events for dynamically connecting and disconnecting displays, with an iOS implementation
Cameron Gutman 771732ed 2020-08-27T17:54:52 windows: Fix numpad arrow key scancodes with numlock off We should only perform the VK_LEFT, VK_UP, etc. mapping if none of the other special mappings apply. This allows the scancode normalization for the number pad to take place as intended.
Cameron Gutman 72379ba5 2020-08-25T21:22:00 windows: Fix handling of swapped mouse buttons GetAsyncKeyState() and GetRawInputData() report the state of the physical buttons without applying the user's primary/secondary mouse button swap preference. Swap the buttons returned from these functions, so we expose a consistent view of the buttons to SDL callers. This new behavior also matches the behavior of macOS and X11 backends. See the Remarks section of the GetAsyncKeyState() function on MSDN.
Ryan C. Gordon b5affd12 2020-07-16T13:28:59 Patched to compile.
Ryan C. Gordon 8babda2c 2020-07-16T13:18:19 egl: SDL_EGL_LoadLibaryOnly() shouldn't set _this->gl_config.driver_loaded = 1 This is handled in in the higher-level SDL_GL_LoadLibrary(). All uses of SDL_EGL_LoadLibrary (which calls the Only version) are just target-specific wrappers for their own GL_LoadLibrary hook, with two exceptions which now handle driver_loaded correctly (although it's questionable if these init-if-no-one-did-it-correctly-already code blocks should exist at all, fwiw). Fixes Bugzilla #5190.
M Stoeckl 052a1373 2020-07-12T19:11:15 Merge VideoBootStrap::available into VideoBootStrap::create The two are only ever called together, and combining them makes it possible to eliminate redundant symbol loading and redundant attempts to connect to a display server.
Sam Lantinga 44f50c64 2020-06-09T21:47:41 Fixed bug 5171 - PollEvent impacts performance in 2.0.12 On some systems, GetClipCursor() impacts performance when called frequently, so only call it every once in a while to make sure we haven't lost our capture.
Sam Lantinga 511a9702 2020-06-09T21:43:00 Fixed whitespace
Sam Lantinga 9325b22e 2020-05-29T21:26:32 Fixed bug 5113 - SDL_UpdateWindowSurfaceRects BitBlt the entire surface on Win32 Ryan C. Gordon As discussed here: https://discourse.libsdl.org/t/question-about-implementation-of-sdl-updatewindowsurfacerects/27561 "As you can see this function [WIN_UpdateWindowFramebuffer, in src/video/windows/SDL_windowsframebuffer.c] calls BitBlt on entire screen, even though it accepts the rects. Rects variable is not even used in this function at all. Now my question is why is that the case?"
Sam Lantinga b6afbe63 2020-04-07T09:38:57 Added SDL_log.h to SDL_internal.h so logging is available everywhere
Sam Lantinga 488b94cb 2020-04-07T09:18:19 Don't interpret raw input messages with no mouse position This happens occasionally on touch devices when raw input is enabled
Sam Lantinga 0721931f 2020-04-06T19:21:56 Avoid sending regular mouse messages for touch input
Sam Lantinga 4dea340c 2020-03-16T12:23:38 Fixed bug 4477 - Support more than 4 XInput-capable devices on Windows Jimb Esser Add new RawInput controller API, and improved correlation with XInput/WGI Reorder joystick init so drivers can ask the others if they handle a device reliably Do not poll disconnected XInput devices (major perf issue) Fix various cases where incorrect correlation could happen Simple mechanism for propagating unhandled Guide button presses even before guaranteed correlation Correlate by axis motion as well as button presses Fix failing to zero other trigger Fix SDL_HINT_JOYSTICK_HIDAPI not working if set before calling SDL_Init() Add missing device to device names Disable RawInput if we have a mismatch of XInput-capable but not RawInput-capable devices Updated to SDL 2.0.13 code with the following notes: New HID driver: xbox360w - no idea what that is, hopefully urelated SDL_hidapijoystick.c had been refactored to couple data handling logic with device opening logic and device lists caused some problems, yields slightly uglier integration than previously when the 360 HID device driver was just handling the data. SDL_hidapijoystick.c now often pulls the device off of the joystick_hwdata structure for some rumble logic, but it appears that code path is never reached, so probably not a problem. Looks like joystick_hwdata was refactored to not include a mutex in other drivers, maintainers may want to do the same refactor here if that's useful for some reason. Something changed in how devices get names, so getting generic names. Had to fix a (new?) bug where removing an XInput controller caused existing controllers (that moved to a new XInput index) to get identified as 0x045e/0x02fd ("it's probably Bluetooth" in code), rendering the existing HIDAPI_IsDevicePresent and new RAWINPUT_IsDevicePresent unreliable.
Sam Lantinga e261bd42 2020-02-12T12:26:27 Improved fix for bug 4748 - Calling WIN_UpdateClipCursor() / WIN_UpdateClipCursorForWindows() on WIN_PumpEvents() causes beeping and choppy mouse cursor movement, right-click doesn't work
Sam Lantinga 6fe6946a 2020-02-11T21:19:05 Fixed relative mode mouse events stopping if you click on the title bar
Sam Lantinga c31727c7 2020-02-11T10:08:22 Fixed bug 4748 - Calling WIN_UpdateClipCursor() / WIN_UpdateClipCursorForWindows() on WIN_PumpEvents() causes beeping and choppy mouse cursor movement, right-click doesn't work The problem here was calling ClipCursor() continuously in a tight loop. Fixed by only calling ClipCursor() if the clip area needs to be updated.
Sam Lantinga 668276fe 2020-02-11T09:41:55 Don't add a frame to borderless windows. It was done to allow hotkey resizing of borderless windows, but Windows will sometimes draw it, regardless of our WM_* message handling. See bug 4466 for more details.
Sam Lantinga f867cebb 2020-02-11T08:36:13 Fixed bug 4709 - incorrect (not) handling of windows on-screen cursor keys Alex Denisov When using Win10 on-screen keyboard (tooltip.exe), the left and right cursor keys in it do not produce SDLK_LEFT and SDLK_RIGHT events. Windows messages generated by the on-screen keyboard, for some reason, have their scancodes set to zeroes. Here is the log from Spy++: WM_KEYDOWN nVirtKey:VK_LEFT cRepeat:1 ScanCode:00 fExtended:0 fAltDown:0 fRepeat:0 fUp:0 WM_KEYUP nVirtKey:VK_LEFT cRepeat:1 ScanCode:00 fExtended:0 fAltDown:0 fRepeat:1 fUp:1 Regular physical keyboard produces VK_LEFT (ScanCode:4B) and VK_RIGHT (ScanCode:4D) which are interpreted correctly. With on-screen keyboard, the switch statement in VKeytoScancode() does not check for VK_LEFT and VK_RIGHT, returning SDL_SCANCODE_UNKNOWN, which in turn does not get mapped to anything (because the scan codes are zeroes).

Sam Lantinga 63197c43 2019-08-02T17:19:50 Fix bug where the wrong button was the default in the old message box because buttons were added backwards, breaking the indexing used by GetButtonIndex. Add messagebox flags to explicilty request left-to-right button order or right-to-left. If neither is specified it'll be some platform default.
Alex Szpakowski d5ec735a 2019-08-01T18:22:12 Add a windowID field to SDL_TouchFingerEvent (bug #4331). This is unimplemented on some platforms and will cause compile errors when building those platform backends for now.
Ozkan Sezer c37c6cbb 2019-07-31T23:37:02 use WIN_IsWindowsVistaOrGreater() from core/windows for isVistaOrNewer
Ozkan Sezer 4953e050 2019-07-31T05:11:40 use SDL_zeroa at more places where the argument is an array.
Sam Lantinga e7c2cf10 2019-07-15T09:36:53 Fixed bug 4704 - SDL_HINT_ANDROID_SEPERATE_MOUSE_AND_TOUCH on Windows? superfury I notice that, somehow, when locking the mouse into place(using SDL_SetRelativeMouseMode), somehow at least the movement information gets through to both mouse movement and touch movement events? My app handles both, so when moving a touched finger accross the app(using RDP from an Android device) I see the mouse moving inside the app when it shouldn't(meaning that the touch movement is ignored properly by the app(press-location dependant) but the mouse movement is still performed due to the mouse movement events)?
Cameron Gutman 7e09718d 2019-07-07T11:23:16 Ignore synthetic mouse events generated for touchscreens Windows generates fake raw mouse events for touchscreens for compatibility with legacy apps that predate touch support in Windows. We already handle touch events explicitly, so drop the synthetic events to avoid duplicates.
Ryan C. Gordon 0beadea5 2019-06-26T01:29:01 windows: Call GetWindowText() with the correct parameters (thanks, Zebediah!) GetWindowText() wants you to tell it the size of the buffer--including the terminating NULL char--but we weren't counting that last char, losing the last char of the string in the process. This was only seen with the special case of SDL_CreateWindowFrom() to use an existing native window, not the usual SDL_CreateWindow() codepath. Fixes Bugzilla #4696.
Ryan C. Gordon 399df540 2019-06-11T01:14:24 windows: Drop WM_ACTIVATE when window is hidden, but only if being activated. Fixes Bugzilla #4571.
Sam Lantinga f2c8d8e9 2019-06-08T10:47:43 Fixed bug 4443 - Incorrect scan code reported for numpad 5 bplu4t2f When num lock is on, the scancode reported for numpad 5 is SDL_SCANCODE_KP_5, which is correct. However, when num lock is off, windows reports the VK_CLEAR virtual key code, which is incorrectly translated into SDL_SCANCODE_CLEAR inside of the VKeytoScancode(WPARAM vkey) function.
Sylvain Becker b45abbb2 2019-04-02T17:57:27 Bug 4576: fix warning and compile
Sylvain Becker 1a4c3b57 2019-04-02T16:58:11 Bug 4576: remove touch/mouse duplication for Windows
Sam Lantinga 5e13087b 2019-01-04T22:01:14 Updated copyright for 2019
Alex Szpakowski 5029d50e 2018-11-10T16:15:48 Add SDL_TouchDeviceType enum and SDL_GetTouchDeviceType(SDL_TouchID id). Touch device types include SDL_TOUCH_DEVICE_DIRECT (a touch screen with window-relative coordinates for touches), SDL_TOUCH_DEVICE_INDIRECT_ABSOLUTE (a trackpad-style device with absolute device coordinates), and SDL_TOUCH_DEVICE_INDIRECT_RELATIVE (a trackpad-style device with screen cursor-relative coordinates). Phone screens are an example of a direct device type. Mac trackpads are the indirect-absolute touch device type. The Apple TV remote is an indirect-relative touch device type.
Ryan C. Gordon 4659e738 2018-11-01T12:31:45 merge fallout: Patched to compile, fixed some compiler warnings, etc.

Ryan C. Gordon b262b0eb 2018-10-22T20:50:32 Small stack allocations fall back to malloc if they're unexpectedly large.
Cameron Gutman eff5f650 2018-10-09T23:01:43 Implement SuspendScreenSaver for Win32 Creating a full-screen SDL renderer on Windows will keep the screensaver suspended by DirectX, as is default for full-screen DX applications. However, for applications that render in windowed-mode, the screensaver will still kick in, even if SDL_DisableScreenSaver() is called or SDL_HINT_VIDEO_ALLOW_SCREENSAVER is set to 0 (default). Implementing a SuspendScreenSaver() function for Win32 fixes this behavior.
Sam Lantinga 55b24b93 2018-09-26T11:17:43 Fixed bug 4265 - SDL window falls to the bottom of the screen when dragged down and stuck there Alexei On WM_WINDOWPOSCHANGED event, WIN_UpdateClipCursor() is called. SDL_WINDOW_INPUT_FOCUS is set even when the mouse pointer is not inside the SDL window and therefore ClipCursor(&rect) is called. When dragging the window and rect.bottom=800 (i.e. the bottom edge of the screen) the SDL window is clipped to the bottom of the screen and it is not possible to move it back to the center of the screen.
Sam Lantinga 5febdfce 2018-09-24T11:49:25 Fixed whitespace
Sam Lantinga 6b3e8931 2018-09-14T19:26:26 Added hints SDL_HINT_MOUSE_DOUBLE_CLICK_TIME and SDL_HINT_MOUSE_DOUBLE_CLICK_RADIUS to allow tuning double-click sensitivity. Also increased the default double-click radius to 32 pixels to be more forgiving for touch interfaces
Sam Lantinga a1ca8441 2018-08-26T20:37:23 Update the cursor clipping each frame, in case it was stolen by another application.
Sam Lantinga 15b3794f 2018-08-26T10:34:23 Only reset the clip rect if it's currently the rect we previously clipped. This prevents us from clearing the clip rect globally when another application has set it. There's also an experimental change to regularly update the clip rect for a window defensively, in case someone else has reset it. It works well, but I don't know if it's cheap enough to call as frequently as it would be called now, and might have other undesirable side effects. Also fixed whitespace and SDL coding style
Ryan C. Gordon e061a92d 2018-08-02T16:03:47 Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.
Ryan C. Gordon 862aa4b4 2018-07-22T19:28:27 windows: Fixed some Visual Studio warnings about shadowed variables. Fixes Bugzilla #4118.
Ozkan Sezer 013b146d 2018-06-30T20:55:51 SDL_windowstaskdialog.h (struct _TASKDIALOGCONFIG): make unions anonymous otherwise build fails. (at least with my VS2005. and the code accesses the arms of the unions anonymously anyway.)
Ryan C. Gordon 7c2028f8 2018-06-29T16:56:11 Attempt to fix "cast from pointer to integer of different size" warnings.
Sam Lantinga 9d6ac3de 2018-06-05T12:46:09 Fix creating a minimized window in SDL to not cause focus to be stolen (because ShowWindow( hwnd, SW_MINIMIZE ) would be called after creation, thus changing focus to the prior window based on some per-app list in windows, rather than the window being created with WS_MINIMIZED to start with). This means we have to consider SDL_WINDOW_MINIMIZED a window creation flag, but on non-windows platforms we just remove it and let the normal FinishWindowCreation re-apply and do the minimize as I have no idea what is right on them or if anything should change. CR: Phil
Sam Lantinga a4d0571e 2018-05-07T20:10:12 Reverted change for bug 4152 - restrict the win10 mouse bug workaround to win10 v1709 only Daniel Gibson Sorry, but it seems like Microsoft didn't fix the issue properly. I just updated my Win10 machine, it now is Version 1803, Build 17134.1 I tested with SDL2 2.0.7 (my workaround was released with 2.0.8) and still got lots of events that directly undid the prior "real" events - just like before. (See simple testcase in attachement) By default it sets SDL_HINT_MOUSE_RELATIVE_MODE_WARP - which triggered (and on my machine still triggers) the buggy behavior. You can start it with -raw, then it'll not set that hint and the events will be as expected. The easiest way to see the difference is looking at the window title, which shows accumulated X and Y values: If you just move your mouse to the right, in -raw mode the number just increases. In non-raw mode (using mouse warping) it stays around 0. I also had a WinAPI-only testcase: https://gist.github.com/DanielGibson/b5b033c67b9137f0280af9fc53352c68 It just calls SetCursorPos(320,240); on each WM_MOUSEMOVE event, and it also logs all those events to a mouseevents.log textfile. This log indeed looks a bit different since the latest Win10 update: It seems like all those events with x=320 y=240 do arrive - but only after I stopped moving the mouse - even though the cursor seems to be moved back every frame (or so). So moving the mouse to the right gives X coordinates like 330, 325, 333, 340, 330, ... and then when stopping movement I get lots of events with X coordinate 320
Sam Lantinga 606c5a58 2018-05-05T10:27:53 Fixed bug 4152 - Windows 10 v1803 update seems to have fixed the jumping mouse bug (see bug #3931.)
Sam Lantinga 6a0ef0cd 2018-04-09T10:37:31 SDL: On Windows, have SDL_ShowWindow() not activate the window if the window has the WS_EX_NOACTIVATE window flag.
Sam Lantinga 4d78a995 2018-03-26T12:38:29 Fixed bug where an SDL window that was activated while hidden could never be shown. Test code: { SDL_Window *win = SDL_CreateWindow( "Dummy", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 128, 128, SDL_WINDOW_HIDDEN ); SDL_SysWMinfo info; SDL_VERSION( &info.version ); SDL_GetWindowWMInfo( win, &info ); SetActiveWindow( info.info.win.window ); { DWORD then = SDL_GetTicks(); while ( ( SDL_GetTicks() - then ) < 3000 ) { SDL_Event evt; SDL_PollEvent( &evt ); } SDL_ShowWindow( win ); then = SDL_GetTicks(); while ( ( SDL_GetTicks() - then ) < 3000 ) { SDL_Event evt; SDL_PollEvent( &evt ); } } SDL_DestroyWindow( win ); }
Sam Lantinga e14278ef 2018-03-24T10:26:40 Fixed bug 3804 - Message box on Windows truncates button ID Simon Hug I just wanted to fix a simple compiler warning in SDL_ShowMessageBox on Windows (which Sam fixed recently) and ended up finding some issues. Attached patch fixes these issues: - Because Windows only reports the lower 16 bits of the control identifier that was pushed, the button IDs used by SDL (C type int, most likely 32 bits) can get cut off. - The documentation states (somewhat ambiguously) that the button ID will be -1 if the dialog was closed, but the current code sets 0. For SDL 2.1, I think this should be a return code of SDL_ShowMessageBox itself. That will free up the button ID and it seems a more appropriate place for signaling this event. - Ampersands in controls will create mnemonics on Windows (underlined letters that, if combined with the Alt key, will push the button). I was thinking of adding a hint or flag to let the users enable it, but that might have unexpected results. - When the size of the text gets calculated, it doesn't use the same parameters as the static control. This can cut off text or wrap it weirdly. - On Windows, the Tab key is used to switch between control groups and sometimes between buttons in dialogs. This didn't seem to work correctly. Attached patch also adds: - Icons. Just the system ones that can be loaded with the ordinals IDI_ERROR, IDI_WARNING and IDI_INFORMATION. - A button limit of 2^16 - 101. - Some more specific error messages, but they never reach the user because how SDL_ShowMessageBox handles them if an implementation returns with an error.
Sam Lantinga 2419d267 2018-03-02T22:53:25 Progress fixing bug 4100 - errors and warnings after changeset 11917 Ozkan Sezer 2018-03-02 20:02:37 UTC http://hg.libsdl.org/SDL/rev/d702b0c54e52 resulted in an error and two warnings when compiled with mingw. 1.

Sam Lantinga 2d7420f2 2018-01-25T11:12:20 Fixed bug 3985 - SDL_CreateWindow() has stopped changing screen mode when SDL_WINDOW_FULLSCREEN is used Anthony This worked in 2.0.5 as normal, but stopped working in 2.0.7. The monitor's resolution doesn't change, a window is created in full screen mode at the virtual desktop resolution instead.
Sam Lantinga 0cba6847 2018-01-15T10:29:53 Fixed bug 4043 - SDL_windowswindow.c incorrect icon height Needed to allocate space for the mask in the ICONIMAGE structure
Sam Lantinga a0c4eb2a 2018-01-10T18:00:51 Restored borderless window behavior where DOTA created a borderless window the size of the desktop and expected it to behave like a fullscreen desktop window. A future SDL release will change the borderless window to act more like a normal window that happens to have no chrome, to support windows that draw their own chrome. In the meantime, those applications should set the "SDL_BORDERLESS_WINDOWED_STYLE" hint.
Sam Lantinga 7c60bec4 2018-01-03T10:58:58 Fixed bug 4018 - Implement SDL_GetWindowBordersSize() under Windows/Win32/WinAPI Ismael Ferreras Morezuelas (Swyter) As a new year gift I have implemented the Windows version of SDL_GetWindowBordersSize(). I needed it for auto-selecting a cozy window size for the game I'm currently working on and noticed that it only worked under X11, so I thought it could be a good excuse to contribute back more stuff. The Mercurial patch is attached as a .diff file. Let me know what you think. Happy 2018 to all the SDL2 devs and users! -- PS: Keep in mind that Windows 10 includes the 8px invisible grip borders as part of the frame. There's a way of detecting if Aero/DWM is being used and ask only for the visible rect, but I believe that GetWindowRect() is doing that for a reason and working as intended, so I haven't changed it.

Ryan C. Gordon 7c667a6f 2018-01-01T19:16:51 windows: Remove references to GetVersionExA (thanks, Andrew Pilley!). "GetVersionExA is deprecated in windows 8.1 and above's SDK, causing a warning when building against the win10 SDK. Attached patch cleans up the usage for a warning-free build. GetVersionExA was being used to test to see if SDL was running on win9x or winnt. A quick chat with Ryan on twitter suggested that SDL doesn't officially support win9x anymore, so the call to this can be outright removed. As an aside, replacing the call to GetVersionExA with VerifyVersionInfoA (the recommended path) would have been pointless, as VerifyVersionInfoA only supports VER_PLATFORM_WIN32_NT and doesn't officially support any other value for dwPlatformId currently. (And it's probable that win9x SDKs didn't have VerifyVersionInfo* in them anyway.)" Fixes Bugzilla #4019.

Sam Lantinga ab06f570 2017-12-10T09:17:33 Workaround for bug 3931 - spurious SDL_MOUSEMOTION events with SDL_HINT_MOUSE_RELATIVE_MODE_WARP 1 since Windows 10 Fall Creators update Elis?e Maurer The attached minimal program sets the SDL_HINT_MOUSE_RELATIVE_MODE_WARP to 1, enables relative mouse mode then logs all SDL_MOUSEMOTION xrel values as they happen. When moving the mouse exclusively to the right: * On a Windows 10 installation before Fall Creators update (for instance, Version 10.0.15063 Build 15063), only positive values are reported, as expected * On a Windows 10 installation after Fall Creators update (for instance, Version 10.0.16299 Update 16299), a mix of positive and negative values are reported. 3 different people have reproduced this bug and have confirmed it started to happen after the Fall Creators update was installed. It happens with SDL 2.0.7 as well as latest default branch as of today. It seems like some obscure (maybe unintended) Windows behavior change? Haven't been able to pin it down more yet. (To force-upgrade a Windows installation to the Fall Creators update, you can use the update assistant at https://www.microsoft.com/en-us/software-download/windows10) Eric Wasylishen Broken GetCursorPos / SetCursorPos based games on Win 10 fall creators are not limited to SDL.. I just tested winquake.exe (original 1997 exe) and it now has "jumps" in the mouse input if you try to look around in a circle. It uses GetCursorPos/SetCursorPos by default. Switching WinQuake to use directinput (-dinput flag) seems to get rid of the jumps. Daniel Gibson A friend tested on Win10 1607 (which is before the Fall Creators Update) and the the bug doesn't occur there, so the regression that SetCursorPos() doesn't reliably generate mouse events was indeed introduced with that update. I even reproduced it in a minimal WinAPI-only application (https://gist.github.com/DanielGibson/b5b033c67b9137f0280af9fc53352c68), the weird thing is that if you don't do anything each "frame" (i.e. the mainloop only polls the events and does nothing else), there are a lot of mouse events with the coordinates you passed to SetCursorPos(), but when sleeping for 10ms in each iteration of the mainloop, those events basically don't happen anymore. Which is bad, because in games the each iteration of the mainloop usually takes 16ms.. I have a patch now that I find acceptable. It checks for the windows version with RtlGetVersion() (https://msdn.microsoft.com/en-us/library/windows/hardware/ff561910.aspx) and only if it's >= Win10 build 16299, enables the workaround. All code is in video/windows/SDL_windowsevents.c and the workaround is, that for each WM_MOUSEMOVE event, "if(isWin10FCUorNewer && mouseID != SDL_TOUCH_MOUSEID && mouse->relative_mode_warp)", an addition mouse move event is generated with the coordinates of the center of the screen (SDL_SendMouseMotion(data->window, mouseID, 0, center_x, center_y);) - which is exactly what would happen if windows generated those reliably itself. This will cause SDL_PrivateSendMouseMotion() to set mouse->last_x = center_x; and mouse->last_y = center_y; so the next mouse relative mouse event will be calculated correctly. If Microsoft ever fixes this bug, the IsWin10FCUorNewer() function would have to be adjusted to also check for a maximum version, so the workaround is then disabled again.

Sam Lantinga 1bfe6d60 2017-10-06T21:43:59 Fixed restoring window size when coming out of fullscreen desktop mode. Use the style of the window as it will be, not as it currently is at the time of the AdjustWindowRect call.
Sam Lantinga 54685787 2017-09-26T15:07:35 Fixed bug 3847 - Hit Test x coordinate wrong on secondary monitor Robert Turner SDL_windowsevents.c contains code to retrieve the x and y coordinate for a requested hit test. It does this as follows: POINT winpoint = { (int) LOWORD(lParam), (int) HIWORD(lParam) }; LOWORD(lParam) does not correctly mask off high bits that are set if the point is on a second (or third, etc.) monitor. This effectively offsets the x-coordinate by a large value. MSDN documentation suggests that LOWORD() and HIWORD() are the wrong macros for the task, instead suggesting we should be doing something like the following: POINT winpoint = { GET_X_LPARAM(lParam), GET_Y_LPARAM(lParam) }; Testing this change on my Windows 10 machine with 2 monitors gives the correct results.

Sam Lantinga 499f928c 2017-09-22T07:15:41 borderless windows will have WM_NCCALCSIZE return 0 for the non-client area. When this happens, it looks like windows will send a resize message expanding the window client area to the previous window + chrome size, so shouldn't need to adjust the window size for the set styles.
Sam Lantinga 3176a7f5 2017-09-22T07:11:36 sdl - Fixing rendering borderless window. Need to force windows to send a WM_NCCALCSIZE then return 0 for non-client area size. - Adding WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX to borderless windows, for reasons noted in comments. - Fix SetupWindowData() setting SDL_WINDOW_BORDERLESS. This was being cleared at window creation, causing hanlding for the first WM_NCCALCSIZE message to fail

Sam Lantinga e8059221 2017-09-08T18:26:25 Fixed bug 3806 - Fixes for MSVC compiler warnings Simon Hug These are the remaining compiler warnings I see in the current tip cb049cae7c3c. - SDL_test_log.c defines _CRT_SECURE_NO_WARNINGS without checking if it was already set. - SDL_windowskeyboard.c converts integers to pointers without going over the (U)INT_PTR types. That bothers MSVC.
