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.

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.
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.
Alex Szpakowski 9306ef9b 2019-06-16T14:10:30 Fix synthetically generated mouse events getting lost forever after the device orientation changes (or the window is otherwise resized) while a finger is touching the screen.
Ryan C. Gordon d9a2eff2 2019-06-13T21:31:03 cocoa: Another attempt at synthesized mouse/touch events.
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.
Sylvain Becker a1a9fd50 2019-04-06T21:43:16 Bug 4581: move tracking appart so it doesn't require the window to have focus
Sylvain Becker e4157618 2019-04-04T16:51:50 Add hint SDL_HINT_MOUSE_TOUCH_EVENTS for mouse events to generate touch events controlling whether mouse events should generate synthetic touch events By default SDL will *not* generate touch events for mouse events
Sylvain Becker ab03892d 2019-04-04T15:19:00 Bug 4576: track both FingerId and TrackId
Sylvain Becker e39c0a1f 2019-04-03T10:14:42 Bug 4576: fix wrong scaling
Sylvain Becker b45abbb2 2019-04-02T17:57:27 Bug 4576: fix warning and compile
Sylvain Becker a3f2c446 2019-04-02T16:46:17 Bug 4576: handle mapping of TouchEvents to MouseEvents at higher level

Sam Lantinga 898644d1 2018-12-06T09:09:05 Made it more clear that the values being compared are floats
Sylvain Becker 252dc85e 2018-12-06T09:22:00 Fix warnings detected on Android build
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.

Sam Lantinga 64dd829b 2017-08-14T13:48:13 Fixed bug 2418 - Structure SDL_gestureTouch leaking Leonardo Structure SDL_gestureTouch gets reallocated for every new added gesture but its never freed. Proposed patch add the function SDL_GestureQuit() that takes care of doing that and gets called when TouchQuit is called. Gabriel Jacobo Thanks for the patch. I think it needs a bit of extra work though, looking at the code in SDL_gesture.c , I see that SDL_numGestureTouches only goes up, I think the right fix here involves adding SDL_GestureDelTouch (hooked into SDL_DelTouch) as well as SDL_GestureQuit (as you posted in your patch).
Sam Lantinga cf31ea14 2017-02-11T11:14:48 Fixed bug 3583 - X11 touch device can be permanently lost Volumetric In X11 the SDL error "Unknown touch device" can occur after which the application stops recognizing touch events. For a kiosk-type application this results in a hang as far as the user is concerned. This is reproducible on HP Z220/Z230/Z240 workstations by swapping USB cables for a while and it also occurs with no physical changes, probably due to USB device power management. A workaround is to make SDL re-enumerate the touch devices like it does at startup. A patch is attached.

Philipp Wiesemann 0e45984f 2015-06-21T17:33:46 Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().
Philipp Wiesemann d8c2b36c 2015-06-12T21:10:31 Fixed crash if allocation for touch device failed. If the allocation of an SDL_Touch failed, the number of touch devices was still increased. Later access of the SDL_Touch would then have dereferenced the NULL.

Ryan C. Gordon b72938c8 2015-04-20T12:22:44 Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.
Alex Szpakowski fe6c797c 2015-04-10T23:30:31 Fixed an iOS view orientation issue when SDL_GL_CreateContext or SDL_CreateRenderer is called.
Edward Rudd b88ca1b4 2015-02-10T16:28:56 the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
Philipp Wiesemann b48e54aa 2015-01-26T22:00:29 Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
David Ludwig 70438be2 2014-12-03T10:55:23 WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!
Philipp Wiesemann 9c398852 2014-11-22T22:20:40 Corrected header file documentation comment.
Pierre-Loup A. Griffais 24c86b55 2014-09-11T19:24:42 [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam
David Ludwig 3dcb451f 2014-04-09T21:29:19 Added a README file regarding WinRT support To note, this file is currently formatted with CRLF line endings, rather than LF, to allow the file to be viewed with Notepad.
Sam Lantinga 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
Ryan C. Gordon 7e1289af 2013-11-24T23:56:17 Make internal SDL sources include SDL_internal.h instead of SDL_config.h The new header will include SDL_config.h, but allows for other global stuff.
Sam Lantinga f79fc33a 2013-08-29T08:29:21 Christoph Mallon: Remove pointless if (x) before SDL_free(x)
Gabriel Jacobo dad42067 2013-08-12T11:13:50 Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
Sam Lantinga 1ad936eb 2013-08-11T19:56:43 Fixed bug 2027 - Full-screen appears to be broken - hang in SDL_DestroyWindow() Rainer Deyke I'm running Linux Mint 15 with the Cinnamon window manager. SDL_DestroyWindow consistently locks up for me when the window if fullscreen.
