This is a functional state for some window managers (tested using stock Ubuntu 22.04.1), and removing that state, e.g. using SDL_RestoreWindow(), results in a window centered and floating, and not visually covering the rest of the desktop.
This uses a newer browser API to get physical scancodes, but still
uses the (deprecated) event field that we were already using for
scancodes, but for keycodes instead now, which appears to be more
accurate.
Since keyboard layout isn't (generally) available to web apps, this
adds an internal interface to send key events with both scancode
and keycode to SDL's internals, instead of sending just scancodes and
expecting SDL to use its own keymap to generate keycodes.
Future work in this area would be to use the keyboard layout APIs
on browsers that support them, which would allow us to use SDL's
usual keymap code and not rely on a deprecated browser API, but
until we get there, this patch gives significantly more correct
results than we would have before.
Fixes#2098.
Exit the fullscreen sequence sooner if it is requested that a popup window be fullscreen.
The surface commit formerly in this path is irrelevant and can be removed as previous changes made it so that SetFullscreen() is no longer called from anywhere except Wayland_SetWindowFullscreen().
The controller can use either hat or buttons for the D-Pad, depending on what Linux driver is in use. The automatic mapping in LINUX_JoystickGetGamepadMapping() will do the right thing based on the exposed capability bits.
I'm sure this is the case for other controllers as well, so we might be removing more mappings over time.
Clear the window to black on the initial window draw, to avoid a really
obnoxious white flash. This doesn't always eliminate it, but it
definitely minimizes it.
This makes the colorspace match across different graphics APIs. By
default, OpenGL was getting a much more saturated colorspace (maybe
Display P3?) and it was looking very different from the rendering done
by Metal or MoltenVK.
- SDL_LoadObject: upon failure, strip the .dll extension and retry,
but only if module name has no path.
- SDL_LoadFunction: upon failure, retry with an underscore prepended,
e.g. for gcc-built dlls.
- strlcpy was passed a wrong buffer length parameter. has worked so
far by luck.
- use memcpy instead of strlcpy for simplicity.
- 'append' has been a typo: should be 'prepend'.
Otherwise the thread might block for a long time (more than 10 seconds!).
It's not clear to me why this happens, or why its safe to do this with a
resource that's still in use, but we have, until recently, always
disposed of the AudioQueue first, so changing back is probably okay.
Also changed the disposal to allow in-flight buffers to reach hardware;
otherwise you lose the last little bit of audio that's already been queued
but not played, which you can hear clearly in the loopwave test program.
Fixes#6377.
Disabling RAWINPUT on Windows 10 causes these issues:
* All Xbox controllers are named "XInput Controller".
* Trigger rumble no longer works.
* "XInput Controllers" are now also listed as separate haptic devices
It's only needed to support more than 4 Xbox controllers, and adds significant complexity to the joystick processing, and we regularly get bugs from people who aren't using an SDL window who need to turn on SDL_HINT_JOYSTICK_THREAD.
Replace instances of fprintf(stderr, ...) with SDL_SetError(), replace C++ comments with C style, use a uniform format for multi-line comments, and remove unused headers as poll and select aren't used in this file (the SDL function which calls them is used instead).
libdecor_dispatch() needs to be called, as libdecor plugins might do some required internal processing within, however care must be taken to avoid double-blocking in the case of a timeout, which can occur if libdecor_dispatch() and the SDL event processing both work on the main Wayland queue. Additionally, assumptions that libdecor will always dispatch the main queue or not process zero-length queues (can occur if a wait is interrupted by the application queueing an event) should not be made, as this behavior is outside the control of SDL and can change.
SDL handles polling for Wayland events and then calls libdecor to do its internal processing and dispatch. If libdecor operates on the main queue, it will dispatch the queued events and the additional wl_display_dispatch_pending() call will be a NOP. If a libdecor plugin uses its own, separate queue, then the wl_display_dispatch_pending() call will ensure that the main queue is always dispatched.
Fixes battery level dropping to empty with the Qanba Drone Arcade Stick.
It looks like we might also be able to skip the check for all third party controllers, but I think this is the right thing to do for Sony controllers as well.
In all cases they were using SDL_SCANCODE_TABLE_XFREE86_2 with some keycodes remapped or fewer than expected keycodes. This adds a sanity check that catches all of them and gives them the right scancode table.
If we can't find the X11 keysym, it's likely that either the keysym is NoSymbol, in which case we won't hit it anyway, or it's been mapped to a character, in which case the existing mapping is correct for the scancode and the character will be reflected in the keycode mapping.
* Consolidated scancode mapping tables into a single location for all backends
* Verified that the xfree86_scancode_table2 is largely identical to the Linux scancode table
* Updated the Linux scancode table with the latest kernel keycodes (still unmapped)
* Route X11 keysym -> scancode mapping through the linux scancode table (which a few hand-written exceptions), which will allow mappings to automatically get picked up as they are added in the Linux scancode table
* Disabled verbose reporting of missing keysym mappings, we have enough data for now
The original code mapped incorrectly from [min, max] to [-32768, 32512], the upper bound being SDL_JOYSTICK_AXIS_MAX - 255 instead of SDL_JOYSTICK_AXIS_MAX.
This will only log things going through dynapi, which means it won't
do anything if dynapi is disabled for a given build, but also things
that call the `*_REAL` version of an API won't log either (which is
to say, if an internal piece of SDL calls a public API, it won't log
it, but if an application calls that same entry point, it will).
Since this just inserts a different function pointer, unless you
explicitly request this at runtime, it won't add any overhead, and,
of course, the entire thing can be turned off with a single #define
so it doesn't even add extra unused code to the shared library if
the kill switch is flipped.
These were needed to fix some buggy behavior regarding committing old buffer sizes when entering fullscreen that has since been corrected. Remove them.
If the compositor is entering fullscreen and hasn't removed any constraints itself, it's already too late at this point. Remove the unnecessary call.
Restoring the limits when exiting fullscreen is still required, though, as they may have been removed when entering fullscreen via an SDL request.
Caches the SDL_HINT_VIDEO_EGL_ALLOW_TRANSPARENCY hint at init time and registers a callback, which is fired when the hint is changed during runtime and toggles the opaque region for existing surfaces.
The preferred method for setting the damage region on compositor protocol versions 4 and above is to use wl_surface.damage_buffer. Use this when available and only fall back to wl_surface.damage on older versions.
Bumps the highest supported version of wl_compositor to version 4.
Adds deduplication logic to ConfigureWindowGeometry() to avoid setting redundant backbuffer, viewport and surface opaque region dimensions. State is now only set when the window and/or backbuffer dimensions change.
This repurposes the viewport rect to always hold the actual size of the window, which can differ from the SDL size if things are being scaled. The SDL_Rect was removed in favor of two ints, as the x/y members of the struct were never used, so they just wasted space.
Since the internal variables always have the true window size, the width/height getter functions are no longer required and can be removed.
Several games (including Source and GoldSrc games, and Bioshock
Infinite) attempt to "fake" relative mouse mode by repeatedly warping
the cursor to the centre of the screen. Since mouse warping is not
supported under Wayland, the viewport ends up "stuck" in a rectangular
area.
Detect this case (mouse warp while the cursor is not visible), and
enable relative mouse mode, which tracks the cursor position
independently, and so can Warp successfully.
This is behind the SDL_HINT_VIDEO_WAYLAND_EMULATE_MOUSE_WARP hint, which
is enabled by default, unless the application enables relative mouse
mode itself using SDL_SetRelativeMouseMode(SDL_TRUE).
Note that there is a behavoural difference, in that relative mouse mode
typically doesn't take mouse accelleration into account, but the
repeated-warping technique does, so mouse movement can seem very slow
with this (unless the game has its own mouse accelleration option, such
as in Portal 2).
Make sure the SDL java and C code match when updating SDL in a game.
Right now we're assuming that we only have to make sure release versions match. We can extend the version string with an interface version if we need more fine grained sanity checking.
