Sylvain 34d4f5b1 2022-02-08T11:32:20 Fixed bug #2032: add SDL_GetTouchName to expose the driver name of the device (Thanks @mgerhardy!)
pionere e2f70a2d 2022-01-19T12:51:26 cleanup SDL_EventState
pionere ebdd5366 2022-01-17T16:26:02 use SDL_InvalidParamError or SDL_assert instead of custom SDL_SetError
Sam Lantinga 84320266 2022-01-25T12:37:43 Fixed the queue filling up with sentinel events when the WaitEvent call is passed NULL for the event The use case is an application that waits for events on the main thread and dispatches them on a separate thread.
ulatekh 8f8b14cb 2022-01-21T17:10:09 Synthesize a missing touch-up event. If a touch-down event is received for an existing touch-ID, that probably means the operating system lost it, and that the missing touch-up should be synthesized, to keep the client state coherent.
Sam Lantinga d8129c56 2022-01-10T10:50:59 Mark internal function as static
Sam Lantinga dca281e8 2022-01-08T08:49:34 Fixed getting different results for SDL_PollEvent(NULL) and SDL_PollEvent(&event)
Sam Lantinga 289c3fbb 2022-01-07T17:07:22 Revert "We only need to add the sentinel at the top of SDL_WaitEventTimeout()" This reverts commit c477768e6f926c38d4cdc236cab8376faf9f6789. We want to add the sentinel anytime we pump inside SDL_WaitEventTimeout() to avoid pumping again the next time through, as a performance optimization.
Sam Lantinga c477768e 2022-01-06T18:58:30 We only need to add the sentinel at the top of SDL_WaitEventTimeout()
Cameron Gutman e9134b04 2022-01-06T19:38:10 events: Only add sentinels for pumping done inside SDL_WaitEventTimeout() We don't want to catch explicit SDL_PumpEvents() calls by the application with our polling check to avoid stale data. If the call to SDL_PumpEvents() produced no events, there will be a sentinel sitting in the queue that will cause SDL_PollEvent() to immediately return 0 next time it is called. Our SDL_WaitEventTimeout() implementation avoids this issue by always popping an event after calling SDL_PumpEvents(). This will remove the new sentinel if we didn't get any new events.
Sam Lantinga 95485884 2022-01-06T13:58:39 Move special sentinel handling inside SDL_PeepEvents()
Sam Lantinga 2592e621 2022-01-06T13:30:26 Clarify that timeout == 0 is handled at the top of SDL_WaitEventTimeout()
Sam Lantinga 8ff21668 2022-01-06T12:56:07 Only return from SDL_PollEvent() if the last sentinel is consumed

Sam Lantinga fd79607e 2021-11-08T21:34:48 Added SDL_GetWindowMouseRect() Also guarantee that we won't get mouse movement outside the confining area, even if the OS implementation allows it (e.g. macOS)

Cameron Gutman a5598649 2021-10-30T19:30:34 x11/wayland: Fix signal handling while blocking in WaitEventTimeout() Add a new flag to avoid suppressing EINTR in SDL_IOReady(). Pass the flag in WaitEventTimeout() to ensure that a SIGINT will wake up SDL_WaitEvent() without another event coming in.
Cameron Gutman ac54d57a 2021-10-26T20:02:38 event: Check subsystem initialization before events or devices SDL_WasInit() is cheaper SDL_NumJoysticks()/SDL_NumSensors().

Sam Lantinga 88e9f776 2021-10-14T18:37:27 Fixed relative mouse mode using warping after https://github.com/libsdl-org/SDL/commit/82793ac279d19b5bde8fc2bd62877b05ba5a76e0
Sam Lantinga 82793ac2 2021-10-14T14:26:21 Fixed mouse warping while in relative mode We should get a mouse event with an absolute position and no relative motion and shouldn't change the OS cursor position at all
Sam Lantinga 1fa154fd 2021-10-13T09:33:54 Fix weak enforcement of timeouts in SDL_WaitEventTimeout_Device. This will loop pumping events and waiting for a system event to come in. However not all system events will turn into an SDL event. It's not unusual for a Windows message to be some internal thing that SDL doesn't convert into a message. In that case the loop will simple circle but not exit. As long as such messages are coming in the loop will continue to run regardless of the timeout. When messages finally stop it'll still wait for the full timeout so you can have arbitrarily long delays. Instead do an absolute elapsed time check since the start of the wait. If that is exceeded during any iteration the routine exits as the timeout has elapsed.
Sam Lantinga 1ec409c2 2021-10-06T09:09:09 Don't warp the mouse within a window while it's minimized
Ethan Lee 7ed415d2 2021-09-23T14:07:38 wayland: Reuse KeySymToUcs4 to replicate X11 keymap behavior
David Gow fbc36490 2021-08-14T22:29:05 Use the new SDL_clamp() macro where sensible There were a few places throughout the SDL code where values were clamped using SDL_min() and SDL_max(). Now that we have an SDL_clamp() macro, use this instead.
Sam Lantinga 69477151 2021-08-13T23:45:01 Get the window size for the window receiving the mouse motion This is the mouse focus except in the case where relative motion is enabled and the mouse is over a window floating on top of the application window (e.g. the taskbar)
Sam Lantinga 6a1e1ed9 2021-08-13T23:36:13 Relative mouse mode grab is based on the window with the input focus This fixes restoring the cursor clip rectangle after the mouse has moved off of the window. Also try to better synchronize cursor visibility with mouse position changes when changing relative mode. This doesn't work perfectly, but it seems to improve things on Windows.
Sam Lantinga b28ed028 2021-08-13T11:39:41 Don't warp the mouse for relative mode when the window doesn't have focus
Sam Lantinga cb1e20b0 2021-08-10T17:50:17 Added KMOD_SCROLL to track the scroll lock state Fixes https://github.com/libsdl-org/SDL/issues/4566
Dean Herbert 8fb95034 2021-04-02T12:52:21 Avoid warping the cursor to the center of the window when not in relative_warp_mode When relative mode is enabled and not using warp mode, the cursor is being clipped to the window. Therefore there is no reason to restore the cursor position to the center. Avoiding the warp to center simplifies mouse position event flow, as we are no longer potentially receiving mouse events for the automated movement of the cursor and can be (mostly) assured that an incoming event from the windowing system is that of external means.
Cameron Gutman 7948c16d 2021-06-12T17:56:52 Pump events each time through the loop in SDL_WaitEventTimeout_Device() Not only is it more efficient to batch process pending events, it is necessary for correctness with the Win32 backend. WIN_PumpEvents() runs periodic updates of the cursor clip region and disambiguation of left and right shift keys in addition to standard event processing.
Cameron Gutman 105de64c 2021-06-12T16:19:03 Only queue one wakeup event per wait Queuing more than one can lead to a spurious wakeup on the next wait.
Ozkan Sezer d28437de 2021-06-12T08:00:50 SDL_keyboard.c: Add bounds guards when assigning to the scancode array. Based on a patch by Jochen Schäfer <josch1710@live.de> : On a T420 pressing the ACPI button for volume control, big scancodes were emitted. This was causing an overflow, because missing guards.
Cameron Gutman e13b43ac 2021-06-05T12:44:08 Don't skip sending wakeups for the current thread We can be in a situation where we receive a win32 hook callback on the same thread that is currently waiting. In that case, we do still need to trigger a wakeup when an event is pushed because the hook itself won't necessarily do that (depending on what we return from the hook).
Cameron Gutman b992b915 2021-06-05T11:57:30 Optimize SDL_WaitEventTimeout() for the SDL_PollEvent() case There's no sense in doing all the setup for waiting if we're just polling.
Cameron Gutman 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.
Cameron Gutman e13d5df0 2021-06-05T11:41:55 Call SDL_SendWakeupEvent() directly from SDL_PeepEvent() SDL_PeepEvent() is a documented public API, so we must properly support waking a waiting thread in SDL_WaitEventTimeout() with SDL_PeepEvent().
Francesco Abbate 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.
Ankith 07fc1bb8 2021-03-15T15:10:49 Fix invalid UTF-8 handling of extra bytes
Cameron Gutman 79cd8cab 2021-01-27T20:41:36 Add default handler for Alt+Tab while keyboard grab is enabled By default, we will minimize the window when we receive Alt+Tab with a full-screen keyboard grabbed window to allow the user to escape the full-screen application. Some applications like remote desktop clients may want to handle Alt+Tab themselves, so provide an opt-out via SDL_HINT_ALLOW_ALT_TAB_WHILE_GRABBED=0.

Sam Lantinga cb361896 2020-12-09T07:16:22 Fixed bug 5235 - All internal sources should include SDL_assert.h Ryan C. Gordon We should really stick this in SDL_internal.h or something so it's always available.

Sam Lantinga bcbaa4ec 2020-05-26T16:34:50 If there isn't a GetGlobalMouseState() implementation, fall back to the normal one.
Ryan C. Gordon fa23e3d0 2020-05-04T02:27:29 locale: Implemented SDL_GetPreferredLocales(). This was something I proposed a long time ago, Sylvain Becker did additional work on it, then back to me. Fixes Bugzilla #2131.

Ryan C. Gordon cd8652d8 2019-10-15T01:13:44 events: SDL_WaitEvent()'s polling loop now sleeps 1ms instead of 10ms. Fixes Bugzilla #4356.
Ryan C. Gordon cf092eca 2019-10-09T13:42:13 mouse: Save initial position yet even if xrel and yrel are 0. The X11 target sets mouse->last_x and last_y in EnterNotify and then calls SDL_SendMouseMotion(), which throws away the new position because it matches the mouse->last_x and last_y we just set, meaning that if the pointer is in the window when it created, SDL_GetMouseState() will report a position of 0,0 until a MotionNotify event (the pointer moves) arrives and corrects the mouse state. Mostly fixes Bugzilla #1612.
Sylvain Becker 70dc8d16 2019-08-30T08:55:20 Android: fix corresponding warnings
Sylvain Becker 2cb26188 2019-08-24T20:40:37 Fixed bug 1663 - SDL_EventState(SDL_DOLLARGESTURE,SDL_IGNORE) etc. has no effect

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.
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)?
Sylvain Becker 66252035 2019-07-09T11:46:42 SDL_Mouse/Touch: discard synthetic events when hints are not set. Those are generated/flagged by platform layer.
Ryan C. Gordon e841b066 2019-07-08T13:41:01 cocoa: Another attempt at mouse vs touch support. This time, we make anything we think is a MacBook trackpad report its touches as SDL_MOUSE_TOUCHID, even though they're not _actually_ synthesized events, and let all mouse input--even if the OS synthesized it from a multitouch trackpad on our behalf--look like physical input. This is backwards from reality, but produces the results most apps will expect. Note that if you have a real touch device that doesn't appear to be the trackpad, it'll produce real touch events with unique device ids, so it's not a total loss here, but also note that the way we decide if it was the trackpad is an imperfect heuristic; it happens to work out right now, but it's not impossible that a real touchscreen could come to the Mac at some point and (incorrectly?) call it a "mouse" input, etc. But for now, good enough. Fixes Bugzilla #4690.

Ryan C. Gordon d9a2eff2 2019-06-13T21:31:03 cocoa: Another attempt at synthesized mouse/touch events.
Ryan C. Gordon 29457464 2019-06-13T01:57:13 cocoa: Revised synthesized mouse/touch event strategy. I _think_ I understand what Sylvain is working on here now, so hopefully I got this right. Fixes Bugzilla #4576. (I think!)
Sam Lantinga e401b950 2019-05-23T11:32:36 Return an error if both mouse relative mode and mouse warping are unavailable, instead of asserting.

Sylvain Becker aae49015 2019-04-10T10:59:53 Fixed bug 4581 - generate synthetic mouse events at window boundaries when real touch events are actually outside the window.
Sylvain Becker cfefe543 2019-04-08T21:27:24 Fixed bug 4581 - mouse events with SDL_TOUCH_MOUSEID make window lost focus Virtual mouse events should never leave the window or change focus for single window applications.

Sam Lantinga b8bd0aa0 2019-03-16T19:07:34 Fixed bug 4450 - SDL_mouse.c fails to compile with CMake generated Visual Studio files if SDL_VIDEO_VULKAN 0/undefined Max Waine SDL_mouse.c, if compiled for Windows, requires GetDoubleClickTime to compile (available from winuser.h). Without Vulkan present this fails to compile as the include chain for winuser.h is the following. SDL_mouse.c -> SDL_sysvideo.h -> SDL_vulkan_internal.h -> SDL_windows.h -> windows.h -> winuser.h. Problem is that SDL_vulkan_internal.h doesn't include SDL_windows.h if Vulkan isn't present, so under MinGW/GCC it will give a -Wimplicit-function-declaration warning for GetDoubleClickTime, and under MSVC fails to compile completely. The solution to this would be to simplify the include chain: including SDL_windows.h under the same condition as GetDoubleClickTime (#ifdef __WIN32__) in SDL_mouse.c (or another file that isn't quite so indirectly included).
