The tm_gmtoff field of the broken-down time 'tm' struct wasn't formally standardized until POSIX.1-2024, but practically it has been available on desktop *nix platforms such as Linux/glibc, FreeBSD, OpenBSD, NetBSD, OSX/macOS (NextStep before that), and others since the 1990s. The notable exception is SunOS/Solaris, where the timezone offset must still be retrieved in the strictly POSIX.1-2008 compliant way.
SDL_IsGamepad() calls SDL_GetJoystickTypeForID(), which will call SDL_IsGamepad() if it's not a known controller type. The new code which is breaking was added to prevent Logitech FFB wheels from showing up as gamepads, which we check for separately.
On Windows 11, apparently HidD_GetManufacturerString() and HidD_GetProductString() can return TRUE without actually filling in any string data.
Fixes https://github.com/libsdl-org/SDL/issues/12566
These changes enable the Logitech G29 wheel to run on hidapi with both SDL_Joystick and SDL_Haptic interfaces.
While it is already possible to use the wheel on Linux in WINE + SDL2 thanks to the in-tree evdev driver as well as new-lg4ff, these set of changes allow the G29 to be used with WINE under MacOS and FreeBSD
These wheels should also be supported, but I can only test them from G29's compat modes: G27, G25, DFGT, DFP, DFEX
Haptic and led support are ported from https://github.com/berarma/new-lg4ff
SDL 2.0.18 added preciseX/Y to mouse wheel events, which we cannot
emulate in sdl2-compat without a mechanism to control integer position
and scroll deltas separately.
The existing behavior helps clients that don't expect exclusive fullscreen windows to move by maintaining a consistent size and mode, however, some are aware that this can occur and want to handle mode selection themselves.
Add a hint to disable auto mode switching when an exclusive fullscreen window moves to accommodate this use case, and don't override fullscreen changes that may occur in an event watcher between the display changed event being posted and SDL running the display changed handler, as the mode switch may have already been handled there by the client.
Move hints used by Emscripten to window properties. This change will be necessary if multiple windows for Emscripten will be supported in the future.
- Added Window Create Property SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_CANVAS_ID
- Added Window Create Property SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_KEYBOARD_ELEMENT
- Use hint SDL_HINT_EMSCRIPTEN_CANVAS_SELECTOR as override to SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_CANVAS_ID
- Use hint SDL_HINT_EMSCRIPTEN_KEYBOARD_ELEMENT as override to SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_KEYBOARD_ELEMENT
- WIN_SetWindowAlwaysOnTop is always called as part of window creation (normally setting HWND_NOTOPMOST) which also set the z-order for the parent
window when child windows are created. Since HWND_NOTOPMOST is above all non-topmost windows this had the effect of reordering but not focusing
the parent window.
With ASAN enabled the existing code triggered null-pointer-dereference
in the strcmp since EMSCRIPTEN_EVENT_TARGET_WINDOW is a "fake" pointer
with the value ((const char*)2). In fixing this it was also noticed
that using the #window/#document/#screen targets as mentioned in the
docs fails since document.querySelector() returns null for them and we
should instead be mapping them to the special HTML targets provided.
