Changing the mode triggers a display reconfiguration event, which will overwrite the desktop mode with the set fullscreen mode, preventing proper restoration when leaving fullscreen. Don't overwrite the desktop mode if the reconfiguration is due to a fullscreen mode switch.
Fullscreen spaces and miniaturization will always give us some notification that they succeeded or failed, so the timeout isn't required. This prevents errant timeouts when live-resize is active.
Additionally, add a warning about calling the frame visibility function universally during the mapping process, as the libdecor Cairo plugin has a bug that will cause a crash in this scenario.
Use the modifier state supplied with key events to track the system modifier state instead of relying on the state returned by XQueryPointer(), which can be racy when used with automated text entry.
A window may have been maximized by dragging it to the top of another display, in which case the floating position may be out-of-date. If the window is being restored to maximized, and the maximized and floating position are on different displays, try to center the window on the maximized display for restoration, which mimics native Windows behavior.
An undefined position means that the window manager can handle placement, so SDL shouldn't override that by forcing a position when showing a window.
Allows for removing a fair bit of now-unnecessary code as well.
SDL_GetWindowDisplayScale() should be preferred over SDL_GetDisplayForWindow() + SDL_GetDisplayContentScale() for querying the per-window content scale, as the former provides a more accurate and current value for individual windows, as the per-window value can differ from the base display scale value, particularly on high-DPI and multi-monitor desktops.
This needs to be preserved while in fullscreen, or leaving fullscreen for the maximized state can cause the taskbar to disappear with borderless windows.
Always restore the base floating size of a window before possibly entering the maximized state, as base size can be lost during the fullscreen transition, resulting in the window de-maximizing to the wrong size.
Update the mouse state before entering the hit test, in case the global state is queried, or the system menu opened, while in the client hit testing callback.
MonitorFromWindow can fail if called on a window being de-minimized, so fall back to using the monitor from the last window coordinates if initial retrieval fails.
Returning anything other an HTCLIENT result will cause windows to eat the button press, so ensure that non-left presses are passed through to the client over draggable areas.
Adds SDL_HINT_VIDEO_MAC_FULLSCREEN_MENU_VISIBILITY to control whether or not the menu can be accessed when the cursor is moved to the top of the screen when a window is in fullscreen spaces mode.
The three values are true, false, and 'auto' (default), with auto resulting in a hidden menu if fullscreen was toggled programmatically, and the menu being accessible if fullscreen was toggled via the button on the window title bar, so the user has an easy way back out of fullscreen if the client app/game doesn't have a readily available option to toggle it.
Add SDL keycodes for keys found commonly found in the default Xkb layout, such as left tab and compose, and keys frequently used for custom modifiers such as Meta, Hyper, and Level5 Shift.
As these keys aren't Unicode code points and don't have associated scancodes (at least on modern keyboards), they are placed in the new extended key code space, with bit 30 set as a flag.
Adds support for Mod3, which is usually Level 5 shift, as well as not altering the functionality of the more esoteric modifier keys, such as meta and hyper.
Also use the system modifier state instead of setting them based on key presses, which may be incorrect due to remapping, or toggled in some other manner.
Adds support for Mod3, which is usually Level 5 shift, but can vary, as well as not altering the functionality of the more esoteric modifier keys, such as meta and hyper.
Non-resizable windows still need to apply the pending size, as they can be resized programmatically.
Fixes programmatically resizing windows without the WS_THICKFRAME style.
A return check conversion was missed when the SDL_* functions were converted to return boolean values instead of int, which caused this test to be skipped.
Apply the supplied xdg-toplevel bounds to resizable windows during initial mapping. Libdecor functionality will have to be added separately, as the functionality needs to be added to the library first.
Find the toplevel parent window, not the absolute highest toplevel window in the hierarchy, when positioning and adjusting the focus of popup windows.
Fixes a leftover case from when toplevel windows couldn't be parented to other toplevels.
Without it, programmatically resizing the window seems to fail. As popup windows are implicitly borderless, calculations taking the frame size into account need to be avoided.
GetClientRect() returns old, incorrect size data for popup windows when called while processing the WM_WINDOWPOSCHANGED message, so use the WINDOWPOS data instead.
Popups can't be maximized or fullscreen, so no need to worry about a move event resizing them.
Don't apply the supplied dimensions if they haven't changed from the last configuration event, or a newer size set programmatically can be overwritten by old data.
This check is already being done for toplevel windows, but was never added to the popup configure event.
Default to using the nearest monitor, instead of null, as a null monitor can be sent when restoring from minimized, which results in the restored, maximized window being the wrong size.
Even if a borderless window doesn't have resizable borders set, the WS_MAXIMIZEBOX property needs to be set on the window, or maximizing it will make it fullscreen and cover the taskbar, instead of only filling the usable desktop space, as is usually expected from a maximized window. This style property needs to be retained until the window is no longer maximized, even if the resize flag is toggled off, or restoring from minimized can fail.
Mouse button numbers are passed through directly, and axis values are passed through as the raw, 32-bit, wl_fixed_t 24.8 fixed-point values, which need to be divided by the denominator to convert to int/float.
Slave pointer devices can seemingly lag behind the master for some reason, so use the master pointer coordinates for absolute motion.
Master events are now only filtered out on the pen path.
It is not uncommon for clients to redundantly set the window size and position, either as a holdover from an SDL 1 port, when this was required, due to any window state change triggering a universal update function that sets all window state, even if unnecessary (e.g. always calling SDL_SetWindowSize(), even if the window is fullscreen), or due to the use of compatability layers. Historically, these clients expect that their behavior won't override the base window state, which is an assumption that the windowing changes in SDL 3 broke by caching size and position changes that can't be applied immediately.
This change drops size and position requests when the window is in the maximized and fullscreen states (fullscreen-desktop windows will be repositioned, but the non-fullscreen floating position will not be overwritten), which is behavior more in line with existing client assumptions, and should ease the porting process, as well as prevent annoying bugs when older software is run via sdl2-compat.
In the process of making these changes, pending window state has been moved to separate variables in the SDL_Window struct, as this fixes bugs regarding fullscreen display selection and centering windows immediately after resize on asynchronous platforms, which had issues due to pending state possibly being overwritten.
Some compositors may not implement commit-timing-v1 in addition to fifo-v1, at least not immediately, and Mesa doesn't require commit-timing for FIFO behavior. The fifo-v1 protocol alone is enough for the desired behavior.
Only check for fifo-v1 to enable Wayland by default.
Unless there are pending client requested window coordinates, such as in the case where the position is set followed by immediately by entering fullscreen, prefer the true window coordinates as sent by the window manager to select a fullscreen display.
Fixes the case where, if the window manager moves an already maximized window to another display, the window would be made fullscreen on the wrong display since the last floating coordinates would be used.
Include SDL_kmsdrmopengles.h before SDL_kmsdrmvulkan.h, as the Vulkan header can pull in Wayland headers, which pull in EGL headers with EGL types defined as Wayland types, which causes warnings when building with strict-aliasing and LTO.
Several functions were redundantly declared in both in the general subsystem header and the GLES header, and some signatures didn't match in both locations.
Move them all to the GLES header, as the definitions are in the GLES source file.
If the maximum size was changed to 0 (unbounded) while a minimum was set, the sanity check ensuring that the max size isn't less than the minimum size would incorrectly cause the operation to error out.
The fullscreen event will be processed after deminiaturization is complete. Fixes a delay when restoring a miniaturized window that will return to fullscreen.
Ensure that fullscreen state is restored if a non-minimized fullscreen window regains key status. This can happen if a fullscreen window was requested to minimize on loss of key status, but the minimization didn't actually occur.
Wayland gives no feedback to windows regarding whether a minimize request was successful, so we would universally send the minimize event and assume that the request succeeded.
Check the window manager capabilities, if available, for whether window minimization is supported, and don't send the minimized event in the case that it is unsupported.
Excessive resize events generated during interactive window resizing can cause applications to lag, severely in some cases. Throttle interactive resize events to once per frame callback interval.
This is already done on win32, however, other platforms were left in a state of limbo if a drop operation began, then never completed due to the drop leaving the window.
The window content scale may change independently of the display it is on if scaling or accessibility features are involved, so query it directly from the backend instead of inferring it.
This protocol is unstable and not intended for clients, and SDL now sorts the display list into a stable order and selects a primary display suitable for games on its own, so it isn't necessary.

Portrait displays are typically used as secondaries and almost certainly not what a user wants a game or movie initially becoming full screen on if a landscape display is available. Increase the priority of selecting a landscape display over a portrait display.
Wayland can expose displays in any arbitrary order, and doesn't have the native concept of a primary display. However, there are games that presume that the first listed display is the primary, which can lead to problems if that output isn't necessarily the ideal one, as they may use that display to build a resolution list or as the default fullscreen output. This sorts displays by position, then attempts to find the primary display, first by querying the explicit ordering hint, then the GNOME DBus property, then tries to determine the 'best' display according to the criteria that is generally ideal for games and media playback.
The makes the list of displays deterministic, as long as the desktop configuration remains static, with a reasonably appropriate one prioritized as primary, even if there is no explicit way to retrieve the primary display. In the case where a user has a particularly esoteric physical display configuration, the new hint enables explicitly overriding the sorting and selection logic, allowing the entire display order to be customized, if necessary.
