61b5360e	2022-10-10T08:27:42	Only check to see if the ICC profile changes when the display changes or we gain focus Fixes https://github.com/libsdl-org/SDL/issues/6366
301912a5	2022-09-18T21:25:55	Fix: Use WIN_ClientPointToSDL for converting additional mouse coordinates
92b3c53c	2022-08-22T16:25:25	Added a hint SDL_HINT_MOUSE_RELATIVE_SYSTEM_SCALE to control whether to use system mouse acceleration on raw relative motion. This is currently only implemented on Windows, and "Enhanced pointer precision" mode is not quite correct.
ffab1396	2022-08-19T17:28:31	Fixed minimized window detection when handling WM_WINDOWPOSCHANGED When minimizing a window, we get this sequence of events: WM_WINDOWPOSCHANGING WM_GETMINMAXINFO WM_NCCALCSIZE WM_WINDOWPOSCHANGED - IsIconic() is true WM_MOVE WM_SIZE - SDL sees minimized state here When restoring a window, we get this sequence of events: WM_WINDOWPOSCHANGING WM_GETMINMAXINFO WM_NCCALCSIZE WM_NCPAINT WM_ERASEBKGND WM_WINDOWPOSCHANGED - IsIconic() is false WM_MOVE WM_SIZE - SDL sees restored state here On Windows 10 a minimized window has a non-empty client rect, so we were delivering a minimized size before SDL knows that the window is minimized, and then ignoring the restored size when handling the restore message. The fix is to use IsIconic() which returns the correct window state when WM_WINDOWPOSCHANGED is actually delivered.
be0cf257	2022-08-12T18:13:42	Only force the resize event in the DPI changed case OpenGL windows don't actually get the WM_WINDOWPOSCHANGED event in the SetWindowPos() call in WIN_SetWindowFullscreen(), so setting the window size to zero never gets reset and we're stuck with a zero sized window. Instead, just force the resize event in WM_DPICHANGED handling, where we know we need it. If we end up needing to force it in WIN_SetWindowFullscreen(), just set a flag in the window data and respond to that in WM_WINDOWPOSCHANGED, but that's a fairly risky behavior change as suddenly all applications would start getting SDL_WINDOWEVENT_SIZE_CHANGED when going fullscreen, and they may respond to that in expensive and potentially disruptive ways. For later we'll probably create a DPI changed event and respond to that in the renderer instead of this window size changed hack. This fixes https://github.com/libsdl-org/SDL/issues/6033 @ericwa
a1e34b5e	2022-08-11T08:52:51	Don't send a resize event when the window is resized to the dock icon Partially addresses https://github.com/libsdl-org/SDL/issues/6033
602b7dd0	2022-08-01T17:47:26	Made the window ICMProfile filename per-window The event no longer spams each time a window gets focus if there are windows on monitors with different color profiles. This also has the side effect that you no longer get a color profile event at window creation, which is consistent with other events that communicate state changes.

af733c7a	2022-06-20T02:26:40	Fix DPI-raised SDL_WINDOWEVENT_SIZE_CHANGED with event callback. Move the sending of this event down so stuff like calling SDL_GL_GetDrawableSize() from a callback reports the new size instead of the old one.
ab81a559	2022-06-07T02:01:27	Windows DPI scaling/highdpi support Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to change the SDL coordinate system units to be DPI-scaled points, rather than pixels everywhere. This means windows will be appropriately sized, even when created on high-DPI displays with scaling. e.g. requesting a 640x480 window from SDL, on a display with 125% scaling in Windows display settings, will create a window with an 800x600 client area (in pixels). Setting this to "1" implicitly requests process DPI awareness (setting SDL_WINDOWS_DPI_AWARENESS is unnecessary), and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.

d3b970d4	2022-05-29T21:56:37	HighDPI: remove SWP_NOSIZE in WIN_SetWindowPosition If the move results in a DPI change, we need to allow the window to resize (e.g. AdjustWindowRectExForDpi frame sizes are different). - WM_DPICHANGED: Don't assume WM_GETDPISCALEDSIZE is always called for PMv2 awareness - it's only called during interactive dragging. - WIN_AdjustWindowRectWithStyle: always calculate final window size including frame based on the destination rect, not based on the current window DPI. - Update wmmsg.h to include WM_GETDPISCALEDSIZE (for WMMSG_DEBUG) - WIN_AdjustWindowRectWithStyle: add optional logging - WM_GETMINMAXINFO: add optional HIGHDPI_DEBUG logging - WM_DPICHANGED: fix potentially clobbering data->expected_resize Together these changes fix the following scenario: - launch testwm2 with the SDL_WINDOWS_DPI_AWARENESS=permonitorv2 environment variable - Windows 10 21H2 (OS Build 19044.1706) - Left (primary) monitor: 3840x2160, 125% scaling - Right (secondary) monitor: 2560x1440, 100% scaling - Alt+Enter, Alt+Enter (to enter + leave desktop fullscreen), Alt+Right (to move window to right monitor). Ensure the window client area stays 640x480. Drag the window back to the 125% monitor, ensure client area stays 640x480.
51ebefee	2022-02-28T00:43:43	Support PMv2 DPI awareness, add SDL_HINT_WINDOWS_DPI_AWARENESS The hint allows setting a specific DPI awareness ("unaware", "system", "permonitor", "permonitorv2"). This is the first part of High-DPI support on Windows ( https://github.com/libsdl-org/SDL/issues/2119 ). It doesn't implement a virtualized SDL coordinate system, which will be addressed in a later commit. (This hint could be useful for SDL apps that want 1 SDL unit = 1 pixel, though.) Detecting and behaving correctly under per-monitor V2 (calling AdjustWindowRectExForDpi where needed) should fix the following issues: https://github.com/libsdl-org/SDL/issues/3286 https://github.com/libsdl-org/SDL/issues/4712

def27267	2022-02-05T12:32:06	Ignore focus change messages that contradict GetForegroundWindow. On Wine, when a window is programmatically minimized in response to losing focus, we receive a WM_ACTIVATE for the deactivation, but GetForegroundWindow still indicates that our window is focused. This causes an incorrect SDL_WINDOWEVENT_FOCUS_GAINED. This is probably a Wine bug, but it may take a while to fix and then for the fix to make its way to users.
829e15a4	2022-02-05T14:38:39	Ignore unknown WM_SIZE types. According to MSDN, we can also get SIZE_MAXHIDE and SIZE_MAXSHOW, based on state changes to other windows. It's not clear under what circumstances this will happen (I saw some docs indicating it may require multiple application windows), but it doesn't seem right to treat them as RESTORED.

53df0e66	2022-01-21T17:15:18	Fix the erroneous generation of mouse-down events from touch-move events. The issue is that MS Windows synthesizes a mouse-move event in response to touch-move events, and those mouse-move events are NOT labeled as coming from a touch (e.g. GetMouseMessageSource() will not return SDL_MOUSE_EVENT_SOURCE_TOUCH for those synthesized mouse-move events). In addition, there seems to be no way to prevent this from happening; https://gist.github.com/vbfox/1339671 claims to demonstrate a technique to prevent it, but in my experience, it doesn't work. Because of this, the "fallthrough" case can't test that the synthesized mouse-move came from a touch-move, and starts erroneously pressing down the mouse-button, leading to massive confusion in the client application.

3bf7994f	2021-09-27T14:38:12	Add and use `SDL_FALLTHROUGH` for fallthroughs Case fallthrough warnings can be suppressed using the __fallthrough__ compiler attribute. Unfortunately, not all compilers have this attribute, or even have __has_attribute to check if they have the __fallthrough__ attribute. [[fallthrough]] is also available in C++17 and the next C2x, but not everyone uses C++17 or C2x. So define the SDL_FALLTHROUGH macro to deal with those problems - if we are using C++17 or C2x, it expands to [[fallthrough]]; else if the compiler has __has_attribute and has the __fallthrough__ attribute, then it expands to __attribute__((__fallthrough__)); else it expands to an empty statement, with a /* fallthrough / comment (it's a do {} while (0) statement, because users of this macro need to use a semicolon, because [[fallthrough]] and __attribute__((__fallthrough__)) require a semicolon). Clang before Clang 10 and GCC before GCC 7 have problems with using __attribute__ as a sole statement and warn about a "declaration not declaring anything", so fall back to using the / fallthrough / comment if we are using those older compiler versions. Applications using SDL are also free to use this macro (because it is defined in begin_code.h). All existing / fallthrough */ comments have been replaced with this macro. Some of them were unnecessary because they were the last case in a switch; using SDL_FALLTHROUGH in those cases would result in a compile error on compilers that support __fallthrough__, for having a __attribute__((__fallthrough__)) statement that didn't immediately precede a case label.
abc12a83	2021-11-11T15:58:44	Revert "Add and use `SDL_FALLTHROUGH` for fallthroughs" This reverts commit 66a08aa3914a98667f212e79b4f0b9453203d656. This causes problems with older compilers: https://github.com/libsdl-org/SDL/pull/4791#issuecomment-966630997

2248a549	2021-11-05T22:48:46	Update the focus in case we changed focus to a child window and then away from the application In this case we'll get WM_KILLFOCUS when the child window is focused, but we'll retain focus on the top level window, but when we Alt-Tab away, we won't get another WM_KILLFOCUS or WM_NCACTIVATE, we get WM_ACTIVATE instead, so we need to check for focus updates in response to that as well.

db68af80	2021-09-24T10:49:44	Reduce the likelyhood that the mouse will hover over the taskbar or toast notification while in relative mode, which causes a mouse leave event. This will still happen occasionally as the mouse is whipped around, if there is a window overlapping the game window, but it should happen less often now. This could even happen with the original code that warped the mouse every frame, so this should be a good compromise where we don't warp the mouse continously and we still keep the mouse in the safe area of the game window. Note that notifications can be any size, so the safe area may need to be adjusted or even dynamically defined via a hint.

91a55a02	2021-08-13T23:59:39	Relative mouse motion is delivered to the window with keyboard focus This was the original intent (note SDL_UpdateWindowGrab() in SDL_OnWindowFocusGained() and SDL_OnWindowFocusLost()) and fixes a bug where relative motion unexpectedly stops if the task bar is covering the bottom of the game window and the mouse happens to move over it while relative mode is enabled. Another alternative would be to confine the mouse when relative mode is enabled, but that generates mouse motion which would need to be ignored, and it's possible for the user moving the mouse to combine with the mouse moving into the confined area so you can't easily tell whether to ignore the mouse motion. See https://github.com/libsdl-org/SDL/issues/4165 for a case where this is problematic.

85b51e6c	2021-06-05T11:46:47	Fall back to polling normally if not operating the win32 message loop In this condition, we cannot safely wait/wake on events.
0dd7024d	2021-03-12T21:58:20	Modifies WaitEvent and WaitEventTimeout to actually wait instead of polling When possible use native os functions to make a blocking call waiting for an incoming event. Previous behavior was to continuously poll the event queue with a small delay between each poll. The blocking call uses a new optional video driver event, WaitEventTimeout, if available. It is called only if an window already shown is available. If present the window is designated using the variable wakeup_window to receive a wakeup event if needed. The WaitEventTimeout function accept a timeout parameter. If positive the call will wait for an event or return if the timeout expired without any event. If the timeout is zero it will implement a polling behavior. If the timeout is negative the function will block indefinetely waiting for an event. To let the main thread sees events sent form a different thread a "wake-up" signal is sent to the main thread if the main thread is in a blocking state. The wake-up event is sent to the designated wakeup_window if present. The wake-up event is sent only if the PushEvent call is coming from a different thread. Before sending the wake-up event the ID of the thread making the blocking call is saved using the variable blocking_thread_id and it is compared to the current thread's id to decide if the wake-up event should be sent. Two new optional video device methods are introduced: WaitEventTimeout SendWakeupEvent in addition the mutex wakeup_lock which is defined and initialized but only for the drivers supporting the methods above. If the methods are not present the system behaves as previously performing a periodic polling of the events queue. The blocking call is disabled if a joystick or sensor is detected and falls back to previous behavior.
157c3f80	2021-05-21T09:45:08	[SDL] Minimize number of system calls when handling WM_INPUT raw input messages. Details: Currently doing 4 system calls per WM_INPUT message, which can cause the thread handling the message loop to be swapped out several times: * GetProp - to get window data from the window handle * GetRawInputData - to retrieve the raw input data * 2 calls to GetMessageExtraInfo - to ignore synthetic mouse events generated for touchscreens In this change: * Replaced GetProp by iterating the list of windows maintained by SDL (with a fallback to GetProp). Note that this will affect all messages and not just WM_INPUT * only calling GetMessageExtraInfo if a touchscreen has been detected Fix for https://jira.valve.org/browse/CSGO-4855 @saml
89b62093	2021-04-01T14:17:53	Fix race condition that can lead to ENTER/LEAVE window events never firing On windows, when toggling the state of RelativeMode rapidly, there is a high chance that SDL_WINDOWEVENT_ENTER / SDL_WINDOWEVENT_LEAVE events will stop firing indefinitely. This aims to resolve that shortcoming by ensuring mouse focus state is correctly updated via WM_MOUSELEAVE events arriving via the windows event hook.
a78bce9e	2021-01-28T20:02:01	Properly handle keys already down when the hook is installed For keys that are already down when we install the keyboard hook, we need to allow the WM_KEYUP/WM_SYSKEYUP message to be processed normally. This ensures that other applications see the key up, which prevents the key from being stuck down from the perspective of other apps when our grab is released.

8c921d82	2021-01-22T19:40:26	Implement keyboard grab support for Windows This is implemented via a low-level keyboard hook. Unfortunately, this is rather invasive, but it's how Microsoft recommends that it be done [0]. We want to do as little as possible in the hook, so we only intercept a few crucial modifier keys there, while leaving other keys to the normal event processing flow. We will only install this hook if SDL_HINT_GRAB_KEYBOARD=1, which is not the default. This will reduce any compatibility concerns to just the SDL applications that explicitly ask for this behavior. We also remove the hook when the grab is terminated to ensure that we're not unnecessarily staying involved in key event processing when it's not required anymore.

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

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.

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).

Fixed minimized window detection when handling WM_WINDOWPOSCHANGED When minimizing a window, we get this sequence of events: WM_WINDOWPOSCHANGING WM_GETMINMAXINFO WM_NCCALCSIZE WM_WINDOWPOSCHANGED - IsIconic() is true WM_MOVE WM_SIZE - SDL sees minimized state here When restoring a window, we get this sequence of events: WM_WINDOWPOSCHANGING WM_GETMINMAXINFO WM_NCCALCSIZE WM_NCPAINT WM_ERASEBKGND WM_WINDOWPOSCHANGED - IsIconic() is false WM_MOVE WM_SIZE - SDL sees restored state here On Windows 10 a minimized window has a non-empty client rect, so we were delivering a minimized size before SDL knows that the window is minimized, and then ignoring the restored size when handling the restore message. The fix is to use IsIconic() which returns the correct window state when WM_WINDOWPOSCHANGED is actually delivered.

2022-08-12T18:13:42

Only force the resize event in the DPI changed case OpenGL windows don't actually get the WM_WINDOWPOSCHANGED event in the SetWindowPos() call in WIN_SetWindowFullscreen(), so setting the window size to zero never gets reset and we're stuck with a zero sized window. Instead, just force the resize event in WM_DPICHANGED handling, where we know we need it. If we end up needing to force it in WIN_SetWindowFullscreen(), just set a flag in the window data and respond to that in WM_WINDOWPOSCHANGED, but that's a fairly risky behavior change as suddenly all applications would start getting SDL_WINDOWEVENT_SIZE_CHANGED when going fullscreen, and they may respond to that in expensive and potentially disruptive ways. For later we'll probably create a DPI changed event and respond to that in the renderer instead of this window size changed hack. This fixes https://github.com/libsdl-org/SDL/issues/6033 @ericwa

Made the window ICMProfile filename per-window The event no longer spams each time a window gets focus if there are windows on monitors with different color profiles. This also has the side effect that you no longer get a color profile event at window creation, which is consistent with other events that communicate state changes.

Windows DPI scaling/highdpi support Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to change the SDL coordinate system units to be DPI-scaled points, rather than pixels everywhere. This means windows will be appropriately sized, even when created on high-DPI displays with scaling. e.g. requesting a 640x480 window from SDL, on a display with 125% scaling in Windows display settings, will create a window with an 800x600 client area (in pixels). Setting this to "1" implicitly requests process DPI awareness (setting SDL_WINDOWS_DPI_AWARENESS is unnecessary), and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.

HighDPI: remove SWP_NOSIZE in WIN_SetWindowPosition If the move results in a DPI change, we need to allow the window to resize (e.g. AdjustWindowRectExForDpi frame sizes are different). - WM_DPICHANGED: Don't assume WM_GETDPISCALEDSIZE is always called for PMv2 awareness - it's only called during interactive dragging. - WIN_AdjustWindowRectWithStyle: always calculate final window size including frame based on the destination rect, not based on the current window DPI. - Update wmmsg.h to include WM_GETDPISCALEDSIZE (for WMMSG_DEBUG) - WIN_AdjustWindowRectWithStyle: add optional logging - WM_GETMINMAXINFO: add optional HIGHDPI_DEBUG logging - WM_DPICHANGED: fix potentially clobbering data->expected_resize Together these changes fix the following scenario: - launch testwm2 with the SDL_WINDOWS_DPI_AWARENESS=permonitorv2 environment variable - Windows 10 21H2 (OS Build 19044.1706) - Left (primary) monitor: 3840x2160, 125% scaling - Right (secondary) monitor: 2560x1440, 100% scaling - Alt+Enter, Alt+Enter (to enter + leave desktop fullscreen), Alt+Right (to move window to right monitor). Ensure the window client area stays 640x480. Drag the window back to the 125% monitor, ensure client area stays 640x480.

Support PMv2 DPI awareness, add SDL_HINT_WINDOWS_DPI_AWARENESS The hint allows setting a specific DPI awareness ("unaware", "system", "permonitor", "permonitorv2"). This is the first part of High-DPI support on Windows ( https://github.com/libsdl-org/SDL/issues/2119 ). It doesn't implement a virtualized SDL coordinate system, which will be addressed in a later commit. (This hint could be useful for SDL apps that want 1 SDL unit = 1 pixel, though.) Detecting and behaving correctly under per-monitor V2 (calling AdjustWindowRectExForDpi where needed) should fix the following issues: https://github.com/libsdl-org/SDL/issues/3286 https://github.com/libsdl-org/SDL/issues/4712

Ignore focus change messages that contradict GetForegroundWindow. On Wine, when a window is programmatically minimized in response to losing focus, we receive a WM_ACTIVATE for the deactivation, but GetForegroundWindow still indicates that our window is focused. This causes an incorrect SDL_WINDOWEVENT_FOCUS_GAINED. This is probably a Wine bug, but it may take a while to fix and then for the fix to make its way to users.

Ignore unknown WM_SIZE types. According to MSDN, we can also get SIZE_MAXHIDE and SIZE_MAXSHOW, based on state changes to other windows. It's not clear under what circumstances this will happen (I saw some docs indicating it may require multiple application windows), but it doesn't seem right to treat them as RESTORED.

Fix the erroneous generation of mouse-down events from touch-move events. The issue is that MS Windows synthesizes a mouse-move event in response to touch-move events, and those mouse-move events are NOT labeled as coming from a touch (e.g. GetMouseMessageSource() will not return SDL_MOUSE_EVENT_SOURCE_TOUCH for those synthesized mouse-move events). In addition, there seems to be no way to prevent this from happening; https://gist.github.com/vbfox/1339671 claims to demonstrate a technique to prevent it, but in my experience, it doesn't work. Because of this, the "fallthrough" case can't test that the synthesized mouse-move came from a touch-move, and starts erroneously pressing down the mouse-button, leading to massive confusion in the client application.

Add and use `SDL_FALLTHROUGH` for fallthroughs Case fallthrough warnings can be suppressed using the __fallthrough__ compiler attribute. Unfortunately, not all compilers have this attribute, or even have __has_attribute to check if they have the __fallthrough__ attribute. [[fallthrough]] is also available in C++17 and the next C2x, but not everyone uses C++17 or C2x. So define the SDL_FALLTHROUGH macro to deal with those problems - if we are using C++17 or C2x, it expands to [[fallthrough]]; else if the compiler has __has_attribute and has the __fallthrough__ attribute, then it expands to __attribute__((__fallthrough__)); else it expands to an empty statement, with a /* fallthrough */ comment (it's a do {} while (0) statement, because users of this macro need to use a semicolon, because [[fallthrough]] and __attribute__((__fallthrough__)) require a semicolon). Clang before Clang 10 and GCC before GCC 7 have problems with using __attribute__ as a sole statement and warn about a "declaration not declaring anything", so fall back to using the /* fallthrough */ comment if we are using those older compiler versions. Applications using SDL are also free to use this macro (because it is defined in begin_code.h). All existing /* fallthrough */ comments have been replaced with this macro. Some of them were unnecessary because they were the last case in a switch; using SDL_FALLTHROUGH in those cases would result in a compile error on compilers that support __fallthrough__, for having a __attribute__((__fallthrough__)) statement that didn't immediately precede a case label.

Update the focus in case we changed focus to a child window and then away from the application In this case we'll get WM_KILLFOCUS when the child window is focused, but we'll retain focus on the top level window, but when we Alt-Tab away, we won't get another WM_KILLFOCUS or WM_NCACTIVATE, we get WM_ACTIVATE instead, so we need to check for focus updates in response to that as well.

Reduce the likelyhood that the mouse will hover over the taskbar or toast notification while in relative mode, which causes a mouse leave event. This will still happen occasionally as the mouse is whipped around, if there is a window overlapping the game window, but it should happen less often now. This could even happen with the original code that warped the mouse every frame, so this should be a good compromise where we don't warp the mouse continously and we still keep the mouse in the safe area of the game window. Note that notifications can be any size, so the safe area may need to be adjusted or even dynamically defined via a hint.

Relative mouse motion is delivered to the window with keyboard focus This was the original intent (note SDL_UpdateWindowGrab() in SDL_OnWindowFocusGained() and SDL_OnWindowFocusLost()) and fixes a bug where relative motion unexpectedly stops if the task bar is covering the bottom of the game window and the mouse happens to move over it while relative mode is enabled. Another alternative would be to confine the mouse when relative mode is enabled, but that generates mouse motion which would need to be ignored, and it's possible for the user moving the mouse to combine with the mouse moving into the confined area so you can't easily tell whether to ignore the mouse motion. See https://github.com/libsdl-org/SDL/issues/4165 for a case where this is problematic.

Fall back to polling normally if not operating the win32 message loop In this condition, we cannot safely wait/wake on events.

Modifies WaitEvent and WaitEventTimeout to actually wait instead of polling When possible use native os functions to make a blocking call waiting for an incoming event. Previous behavior was to continuously poll the event queue with a small delay between each poll. The blocking call uses a new optional video driver event, WaitEventTimeout, if available. It is called only if an window already shown is available. If present the window is designated using the variable wakeup_window to receive a wakeup event if needed. The WaitEventTimeout function accept a timeout parameter. If positive the call will wait for an event or return if the timeout expired without any event. If the timeout is zero it will implement a polling behavior. If the timeout is negative the function will block indefinetely waiting for an event. To let the main thread sees events sent form a different thread a "wake-up" signal is sent to the main thread if the main thread is in a blocking state. The wake-up event is sent to the designated wakeup_window if present. The wake-up event is sent only if the PushEvent call is coming from a different thread. Before sending the wake-up event the ID of the thread making the blocking call is saved using the variable blocking_thread_id and it is compared to the current thread's id to decide if the wake-up event should be sent. Two new optional video device methods are introduced: WaitEventTimeout SendWakeupEvent in addition the mutex wakeup_lock which is defined and initialized but only for the drivers supporting the methods above. If the methods are not present the system behaves as previously performing a periodic polling of the events queue. The blocking call is disabled if a joystick or sensor is detected and falls back to previous behavior.

[SDL] Minimize number of system calls when handling WM_INPUT raw input messages. Details: Currently doing 4 system calls per WM_INPUT message, which can cause the thread handling the message loop to be swapped out several times: * GetProp - to get window data from the window handle * GetRawInputData - to retrieve the raw input data * 2 calls to GetMessageExtraInfo - to ignore synthetic mouse events generated for touchscreens In this change: * Replaced GetProp by iterating the list of windows maintained by SDL (with a fallback to GetProp). Note that this will affect all messages and not just WM_INPUT * only calling GetMessageExtraInfo if a touchscreen has been detected Fix for https://jira.valve.org/browse/CSGO-4855 @saml

Fix race condition that can lead to ENTER/LEAVE window events never firing On windows, when toggling the state of RelativeMode rapidly, there is a high chance that SDL_WINDOWEVENT_ENTER / SDL_WINDOWEVENT_LEAVE events will stop firing indefinitely. This aims to resolve that shortcoming by ensuring mouse focus state is correctly updated via WM_MOUSELEAVE events arriving via the windows event hook.

Properly handle keys already down when the hook is installed For keys that are already down when we install the keyboard hook, we need to allow the WM_KEYUP/WM_SYSKEYUP message to be processed normally. This ensures that other applications see the key up, which prevents the key from being stuck down from the perspective of other apps when our grab is released.

Implement keyboard grab support for Windows This is implemented via a low-level keyboard hook. Unfortunately, this is rather invasive, but it's how Microsoft recommends that it be done [0]. We want to do as little as possible in the hook, so we only intercept a few crucial modifier keys there, while leaving other keys to the normal event processing flow. We will only install this hook if SDL_HINT_GRAB_KEYBOARD=1, which is not the default. This will reduce any compatibility concerns to just the SDL applications that explicitly ask for this behavior. We also remove the hook when the grab is terminated to ensure that we're not unnecessarily staying involved in key event processing when it's not required anymore.

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

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.

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).
