SDL_StartTextInput(), SDL_StopTextInput(), SDL_TextInputActive(), SDL_ClearComposition(), and SDL_SetTextInputRect() all now take a window parameter.
This change also fixes IME candidate positioning when SDL_SetTextInputRect() is called before SDL_StartTextInput(), as is recommended in the documentation.
Switching between layouts with the same group number (e.g. US to Japanese) were incorrectly filtered out with this change, as it doesn't trigger a MappingNotify event.
This reverts commit 3d42412650.
KeymapNotify events happen on focus events, as well as when the key group changes. Query the current group and don't rebuild the keymap if it hasn't changed.
XkbKeycodeToKeySym is replaced with XkbLookupKeySym, which can take the modifier states. The associated cmake check has been renamed for consistency.
Only the XKB path is currently handled. The deprecated XKeycodeToKeysym path is TODO.
Normally this would be done by creating a PQ swap chain and a linear SRGB render target and doing blending operations in linear space and then final conversion to PQ HDR, but we're going to short-circuit all of that and just support linear SRGB output directly.
Proton uses this on Linux to determine what the XInput slot is for the gamepad. Other applications will get the real controller name and VID/PID by virtue of the code in SDL_steam_virtual_gamepad.c
I _did_ appreciate the explanation, but it doesn't have to live in the
source code; also we can just release `devuid` and then check for error with
the usual macro, since SDL is done with it either way at this point.
A minimized window may not be associated with any displays, so check that the output array is valid and that there is at least one associated display before dereferencing.
Fixes a crash when attempting to unset fullscreen on a minimized window.
For GTK-based systems using XSETTINGS it's much more likely to be
available, rather than the "GDK_SCALE" environment variable, which is a
debugging tool according to the GTK documentation.
Import the XSettingsClient implementation to handle the settings
selection.
Currently, we only care about the Gdk/WindowScalingFactor value used by
the windowing system to notify us of display-wide changes in the scaling
factor.
