To match the focus stealing prevention logic from windows/osx.
I didn't implement SDL_HINT_WINDOW_ACTIVATE_WHEN_SHOWN as there is no
standard mechanism for us to do so. In most cases marking a window as OverrideRedirect
will cause to not acquire focus when mapped. And in steam we are doing that when
appropriate.
I still left a note in X11_ShowWindow() regarding this behaviour.
- Cocoa_ShowWindow will order a window that is not being activated below the key window (if one exists) then set visible
- Cocoa_RaiseWindow calls -[NSWindow orderFront:] without changing the key window
Also renamed SDL_GetDisplayOrientation() SDL_GetDisplayCurrentOrientation()
The natural orientation of the primary display is the frame of reference for accelerometer and gyro sensor readings.
This prevents the case where the mouse might be at the edge of the
window when enabling relative mode, which confuses macOS, at it
might believe the user is attempting to resize the window.
Fixes#6994.
(cherry picked from commit 2afb49ba9a)
Hiding a window and then clearing the minimized, maximized, fullscreen, or grabbed flags wouldn't result in the new state being applied to the window when shown, as the pending flags would always be zero, resulting in the flag application function never being entered. Calling SDL_RestoreWindow() didn't result in the minimized or maximized state being cleared on the hidden window either.
Save the current window flags to the pending flags when hiding a window, and universally apply the pending flags when the window is shown again to ensure that all state that was set or cleared when the window was hidden is applied. Any pending flags that match the existing window flags will be automatically deduplicated by the corresponding functions.
- Removed the blanking window used in SDL_WINDOW_FULLSCREEN. This allows CMD + Tab to work.
- Changed the fullscreen NSWindow level so this works properly.
Fixes issue #7776
1. Send display disconnected events for all displays no longer connected
2. Send display connected events for all displays that have been connected
3. Send window display events for any windows that have changed displays
Add aspect-correct output of scaled video modes and a hint to control this behavior (aspect, stretch, or none).
The Wayland spec states that fullscreen surfaces that do not cover the entire output shall be centered with the borders masked by the compositor, so no additional work is required aside from calculating the proper window dimensions.
The default is still 'stretch' mode, as some window managers as of this time (KDE and older versions of GNOME still found in LTS distros) don't behave according to the spec and present an unmasked window that is not centered, so it's not yet safe to change the default.
- Fix places working with window coordinates that need to call SDL_RelativeToGlobalForWindow or SDL_GlobalToRelativeForWindow
- Remove NSScreen param from ConvertNSRect(). Reflecting the Y coordinate is done relative to the main screen height (which ConvertNSRect
was already doing) so the explicit screen isn't needed.
- Refactor NSScreen lookups for point/rect and fix getting the screen for Cocoa_SetWindowPosition() to get the screen for the new position and
not the window's current screen (which may not exist if the window is off-screen).
- Fix re-associating the popup and parent window when the child window is shown. Hiding a child window removes it from the window hierarchy
and so must be added when the window is shown again.
- Allow popup windows that are not tooltips to gain key focus.
Consolidate the X11_WMCLASS and WAYLAND_WMCLASS envvars into one SDL_HINT_APP_ID hint. This hint serves the same purpose on both windowing systems to allow desktop compositors to identify and group windows together, as well as associate applications with their desktop settings and icons.
The common code for retrieving the value is now consolidated under core/unix/SDL_appid.c as it's common to *nix platforms, and the value is now retrieved at window creation time instead of being cached by the video driver at startup so that changes to the hint after video initialization and before window creation will be seen, as well as to accommodate cases where applications want to use different values for different windows.
XRandR supports applying transformations to an output's picture
including changes to scale. Such scaling is used by some desktop
environments under feature names such as "fractional scaling" to
accomodate HiDPI devices. Alternatively, such scaling can be enabled by
a command such as the following:
xrandr --output DP1 --scale 0.5x0.5 --filter nearest
XRandR scaling has no "HiDPI awareness" or other way for an application
to signal that it wants to work with physical display pixels, and so all
we do is scale SDL's returned display modes so that applications receive
the number of usable pixels that they expect.
There are many toolkit specific ways to set a font DPI in X11 desktop
environments. The primary approach of reading a Gnome specific setting
from the portal is ok, it will work on Gnome and on Plasma most the
time.
The current fallback GDK_SCALE is less great; it's an internal GTK
setting relating to the mapping of logical pixels to device pixels
within the toolkit, it's a developer setting for GTK devs. We were
instructed within Plasma to not set this as it caused issues.
Xft.dpi in xresources is a good universal fallback, it's very dated to
the point that it works in clients like xterm, Qt on X11 uses it in our
font DPI path.
Re-writes clipboard data handling in X11 to an on demand approach where
data can be produced on request instead of storing it in X11 properties
on the window.
Primary selection has been changed to mimic this behavior even though
it's only possible to use it for text as of now.
Ensure that incoming touch events originate from valid surfaces owned by SDL and have proper window data before forwarding them to the touch subsystem, or the window focus pointer that is sent with the event may not be a pointer to an SDL window.
Additionally, ensure that allocated touch events are always cleaned up on exit.
- SDL_MaximizeWindow, MinimizeWindow, SetFullScreenWindow, etc are not meant to show the window if it isn't currently visible, but on some platforms
(e.g. Windows) it isn't possible to set this state without also showing the window so cache the flags in a pending_flags field until SDL_ShowWindow is
called. Then replay the pending flags through ApplyPendingFlags (hoisted out from SDL_FinishWindowCreation).
