Don't be fooled by the diff size - this ended up being a big refactor of the
shell surface management, masked only by some helper macros I wrote for the
popup support.
This change makes it so when xdg_decoration is supported, but CSD is requested,
the system bails on xdg support entirely and resets all the windows to use
libdecor instead. This transition isn't pretty, but once it's done it will be
smooth if decorations are an OS toggle since libdecor will take things from
there.
In hindsight, we really should have designed libdecor to be passed a toplevel,
having it manage that for us keeps causing major refactors for _every_ change.
* Add changes from code review by @ccawley2011, #5597, overall cleanup
* Update N-Gage README, minor cleanup and rephrasing
* Call SDL_SetMainReady() before calling SDL_main, return SDL_main instead of main
Change Cocoa SDL_VideoData and SDL_WindowData implementations from C structs to Objective-C objects, since bridging between C and ObjC is easier that way.
* Add initial support for the Nokia N-Gage
* N-Gage: disable clipping for the time being, issue needs to be resolved later
* Move va_copy definition to SDL_internal.h
* Move stdlib.h include to SDL_config_ngage.h, much cleaner this way
* Remove redundant include, add HAVE_STDLIB_H
* Revert "N-Gage: disable clipping for the time being, issue needs to be resolved later"
This reverts commit 4f5f0fc36c.
* N-Gage: fix clipping issue by providing proper math functions
We can get _some_ of the info we need out of standard Xlib and report a
single display (which might actually be multiple physical displays mushed
into a single desktop). This is better than nothing, but you should really
just build with XRandR support and get a better X server. :)
When mode switching is disabled in a video backend, fullscreen windows are basically just fullscreen desktop windows with different internal scaling. As no mode switching occurs, there's no need to minimize them on focus loss by default. This can still be overridden by explicitly setting the internal hint for minimizing on focus loss.
This has the side effect of fixing a bug on GNOME, where, when a fullscreen Wayland window has it's focus lost and restored via alt+tab followed by switching back to windowed mode, the top portion of the window won't end up being obstructed by GNOME's top bar.
This reverts commit 8ceba27d62.
SDL Wayland support is stable, but there are a number of issues with third-party software (NVIDIA drivers, libwayland event overflow, libdecor not handling plugin load failures, Steam overlay not working with Wayland, etc.) that make it better to default to X11 at this time.
Games which would like to prefer wayland when available can use the following code before SDL_Init():
SDL_SetHint(SDL_HINT_VIDEODRIVER, "wayland,x11");

This hint allows libdecor to be used even when xdg-decoration is
available. It's mostly useful for debugging libdecor, but could in
theory be used by applications which want to (for example) bundle their
own libdecor plugins.
When using emulated display modes, the output size is often larger than the drawable buffer. As the surface damage region is automatically calculated from the smaller drawable buffer size, the damage region needs to be manually set to cover the entire viewport region or visual repaint artifacts can result.
I kind of thought it'd be nice to have it in the center, but this is an issue
for applications that still assume global mouse and window positions are
accessible. For example, this fixes cursor offset issues in UE5.
It's possible that an external component (probably a GL/VK context) committed, so we need to cover our bases and detach in both HideWindow and ShowWindow.
Fixes a crash in UE5 editor's pop-ups.
Partially fixes the mouse cursor in UE5 editor. Imperfect because UE5 uses window position and global mouse state to get position, but of course we don't have global mouse and this is just to get the right display index so this still fails overall. We really need to make global mouse support a feature query...
So if Gnome/KDE/etc have a keyboard shortcut or titlebar decoration to
make any window go fullscreen (with the _NET_WM_FULLSCREEN flag on the
_NET_WM_STATE property), we update the SDL window flag.
Fixes#5390.
This makes sure the window doesn't have outdated values if you try to access
them (or call something that does, like SDL_SetWindowMinimumSize).
Fixes#5233.
