Ethan Lee ae7ee2a5 2021-08-11T09:59:43 wayland: Ignore stateless/sizeless configs when starting in fullscreen mode
Ethan Lee 7be970db 2021-08-06T19:51:27 wayland: Avoid setting floating width/height when re-entering fullscreen
Ethan Lee 10979d37 2021-08-05T12:42:03 wayland: Always assume configure is wrong for non-resizable windows. Configure events from compositors have an extremely annoying habit of giving us completely bogus sizes, from all sorts of places. Thankfully, the protocol gives us the ability to completely ignore the width/height and just stick with what we know, so for all windows that are not meant to be resized, pretend we never even got the width/height at all, the compositor is required to respect our dimensions whether they match configure's suggestion or not.
Ethan Lee 32f909f7 2021-08-03T13:30:57 wayland: Remove redundant waylanddyn.h includes. All files including waylanddyn.h already include waylandvideo.h first.
Ethan Lee 7082fb04 2021-08-02T22:42:28 wayland: Only dispatch on fullscreen set when the window is visible. Fixes hang-on-startup described in #4572.
Ethan Lee 0f5b8a99 2021-08-02T19:48:31 wayland: For libdecor, dispatch immediately after setting fullscreen Reference: #4578
Ethan Lee 4562da62 2021-08-02T16:40:56 wayland: Make libdecor configure match xdg_toplevel
Ethan Lee 1fb1aa19 2021-08-02T12:57:28 wayland: Keep the fullscreen check for maximize/restore events
Ethan Lee 584673a5 2021-08-02T12:51:23 wayland: Don't ignore configs for non-fullscreen, non-resizable windows. This was causing configure events to not inform SDL of window size changes, even when they were based on resizes that we fully expected. The result was fullscreen->windowed not working at all, because it would retain the desktop resolution instead of reverting to the floating size that it had before moving to fullscreen mode. Fixes Super Hexagon fullscreen toggling.
Sebastian Krzyszkowiak 25067298 2021-08-02T08:15:10 wayland: Flush in SetWindowFullscreen The flush has been removed in e5f9fae034df8ca305241c5a666e7702fcf9958f. Unfortunately, even though ideally the flush shouldn't be necessary, our resize sequence isn't... well, perfect, and removing that flush causes tons of troubles. We're also still flushing in other paths where the window size can be changed by the compositor and where we may potentially have to obey that change, like in Wayland_MaximizeWindow. This also removes the hack introduced in 7f261d3b7667978ced93a4fdc6aec2380df3d87f, which introduces problems with protocol violations and seems to not be necessary when flushing.
Sebastian Krzyszkowiak ea28187c 2021-08-02T08:07:23 wayland: Hack surface resize into compliance with set_window_geometry We have issues with correct resize sequence and happen to commit old-sized buffers even after configure event for the new size has been already acknowledged. While the reason for that stays unknown, let's at least workaround the problem by faking window geometry into expected size. This does not fix visual glitch on e.g. fullscreen toggling, but having a split-second glitch is still a much better outcome than being terminated by the compositor for protocol violation.
Sebastian Krzyszkowiak b5210cac 2021-08-02T13:47:32 wayland: Initialize floating size at window creation This allows the windowed size to be restored for windows initially created already in non-floating state.
Ethan Lee dab33844 2021-08-02T11:58:47 wayland: Fix a warning in handle_configure_xdg_toplevel
Ethan Lee 754aa2d3 2021-08-02T11:55:02 Mostly revert cfcdfb7be9f5c97a51ddef9ad3677a604856266b. This was causing window changes to completely break, resulting in broken decorations and bizarre frame timing, I don't know what exactly it's doing but it's not good. Kept the libdecor_frame_is_floating logic, at least.
Ethan Lee 8803589f 2021-08-02T12:05:06 wayland: Avoid redundant SetWindowBordered for libdecor
Sebastian Krzyszkowiak b4c4060a 2021-08-02T04:52:25 wayland: Clean up Wayland_HandlePendingResize Commit 871c11191bfc7214061a3da37c112522a102ddf5 removed delayed resize handling, but it left the whole structure untouched that now became unnecessary. To help with code clarity, get rid of the structure where pending resize state used to be stored and pass all the data directly to Wayland_HandlePendingResize (now renamed to Wayland_HandleResize, since it's not "pending" anymore but applied immediately)
Sebastian Krzyszkowiak 9bb24ad0 2021-08-02T05:49:35 wayland: Always call Wayland_SetWindowBordered when showing the window Otherwise our windows have no window decoration on compositors that support xdg-decoration-unstable-v1, but default to client-side mode. Contrary to what the comment was stating, there is nothing in the protocol that would make redundant calls to zxdg_toplevel_decoration_v1::set_mode problematic.
Christian Rauch cfcdfb7b 2021-08-01T18:14:53 libdecor: use same fullscreen/maximised restore logic as for xdg-toplevel
Christian Rauch 42452f8c 2021-08-01T13:51:30 wayland: store and restore floating states Some Wayland compositors send (0,0) as "suggested" configure event sizes to indicate that the client has to decide on its own which sizes to used. This is commonly done when restoring from maximised, fullscreen or tiles states to fullscreen. We now store the last known floating states in a new set of variables and restore them when we receive such a (0,0) configure event.
Ethan Lee 71897cc1 2021-07-30T15:51:43 wayland: Always trigger a resize when handling a configure event. When we removed the OpenGL resize workaround it introduced a problem for fullscreen windows in particular: When leaving fullscreen we tried to send a resize event, but UpdateFullscreenMode would send a SIZE_CHANGED immediately after, deleting our resize event and causing the following configure event's resize to be ignored. This timing issue resulted in fullscreen windows not being resized at all when becoming a floating window. By always forcing resize events from configure events, we ensure that RESIZED always makes it through. SetWindowSize-type changes should be unaffected as they do not fire configure events.
Ethan Lee c20ab7da 2021-07-30T00:22:50 wayland: Fix GetWindowWMInfo for <2.0.15

Ethan Lee 93976ade 2021-07-28T12:22:09 wayland: libdecor support for GetWindowWMInfo
David Gow 21cba924 2021-07-28T16:54:23 wayland: Don't create zxdg toplevel decoration twice Each window can have at most one zxdg toplevel decoration, but as of [1], we accidentally create two. (If libdecor is not in use). This causes wayland windows with server-side decorations (e.g. on KDE/KWin) to crash with the message: zxdg_decoration_manager_v1@7: error 1: decoration has been already constructed This extra zxdg_decoration_manager_v1.get_toplevel_decoration() call was introduced while deprecating wl-shell and xdg-shell-stable[1] support, and possibly was a bad interaction with [2], which moved the decoration creation around. Fixes: 6aae5b44f8 ("Remove wl-shell and xdg-shell-unstable-v6 support (#4323)") [1]: https://github.com/libsdl-org/SDL/pull/4323 [2]: https://github.com/libsdl-org/SDL/pull/4374
Ethan Lee 7b239edb 2021-07-28T01:00:00 wayland: Assign frame_callback on window creation. Fixes a crash when creating and destroying a window without calling SwapWindow.
Ethan Lee 03185e74 2021-07-27T18:35:00 wayland: Tag/Check wl_output objects as well, fixes crashes when libdecor is in use
Ryan C. Gordon 871c1119 2021-07-27T18:24:09 wayland: handle pending resizes immediately, not on SwapWindow. This was originally a workaround for an old Mesa bug, since fixed, apparently, and causes other problems. Fixes #4326.
Ethan Lee a3eb297e 2021-07-27T17:17:19 wayland: Rework enter/leave and update_scale_factor to avoid bogus wl_output data. Also remove get_window_scale_factor() which was just pointless indirection.

Sam Lantinga f1633127 2021-07-24T13:41:55 Added a window flash operation to be explicit about window flash behavior
Sam Lantinga e1c3a250 2021-07-24T12:11:27 Changed SDL_FlashWindow() so it doesn't take a flash count, and added the hint SDL_HINT_WINDOW_FLASH_COUNT to control behavior on Windows
meyraud705 4ada14a2 2021-07-21T13:39:10 Replace libc functions to SDL equivalent in wayland video subsystem Wayland video subsystem uses a mix of libc and SDL function. This patch switches libc functions to SDL ones and fixes a mismatch in memory allocation/dealoccation of SDL_Cursor in SDL_waylandmouse.c (calloc on line 201 and SDL_free on line 313) which caused memory corruption if custom memory allocator where provided to SDL.
Ethan Lee 7f261d3b 2021-06-15T00:35:13 wayland: Fix returning to a window from fullscreen without calling SetWindowSize

Ethan Lee 20928550 2021-05-01T09:00:24 wayland: Guard surface_frame_listener for OpenGL, document why it exists
Ryan C. Gordon c54c16d3 2021-04-30T13:19:36 wayland: don't hang in SDL_GL_SwapBuffers if the compositor is ghosting us. If you hide a window on Mutter, for example, the compositor never requests new frames, which will cause Mesa to block forever in eglSwapBuffers to satisfy the swap interval. We now always set the swap interval to 0 and manage this ourselves, handing the frame to Wayland when it requests a new one, and timing out at 10fps just to keep apps moving if the compositor wants no frames at all. My understanding is that other protocols are coming that might improve upon this solution, but for now it solves the total hang. Fixes #4335.
Ethan Lee 8e3ec34d 2021-04-20T12:40:40 wayland: Refactor toplevel mapping, implement HideWindow

Ethan Lee ed24c345 2021-04-16T21:35:50 wayland: Implement basic window move events via wl_surface_listener. This unearthed an unspeakably large amount of bugs in the wl_output enumerator, notably the fact that the wl_output user pointer was to temporary memory! This was "fixed" in e862856, and was then pointed out as a leak in 4183211, which was undone in d9ba204. The busted fix was correct that the malloc was an issue, but wrong about _why_; SDL_AddVideoDisplay copies by value and does not reuse the pointer, so generally you want your VideoDisplay to be on the stack, but of course the callbacks don't allow that, so a malloc was a workaround. But we can do better and just host our temporary display inside WaylandOutputData because that will be persistent while also not leaking. Wait, wasn't I talking about move events? Right, that: wl_surface_listener does at least give us the ability to know what monitor we're on, even though we have no idea where we are on the monitor. All we need to do is check the wl_output against the display list and then push a move event that both indicates the correct display while also not being _too_ much of a lie (but enough of a lie to where our event doesn't get discarded as "undefined" or whatever). The index check for the video display is what spawned the great nightmare you see before you; aside from the bugfix this is actually a really basic patch.
David Edmundson f6a09ef1 2021-04-07T16:16:23 wayland: Drop support for kwin specific decoration management KWin has supported the shared and formalised zxdg_decoration since Plasma 5.16 which came out mid 2019. Whilst it made sense to support them both for a while, it should not be needed for future SDL releases.
Ethan Lee a92cca1a 2021-04-07T16:44:10 wayland: Use the window's display to get wl_output rather than fullscreen_mode. Because Wayland only supports FULLSCREEN_DESKTOP, fullscreen_mode never gets assigned at all, meaning driverdata is always NULL! Depending on what the compositor does this can lead to dramatically different results. GNOME was fine without this, but Plasma would trip an event that unintentionally unset the fullscreen mode and caused the game to fire a configure event _every frame_, and of course the configure would send the fullscreen_mode output which was still empty. The fix is to just use the SDL_VideoDisplay directly, which will always have a valid wl_output.

Cameron Gutman e1f73e64 2021-01-23T16:22:44 Refactor keyboard grab to be managed by the video core This gives us flexibility to add others hints to control keyboard grab behavior without having to touch all of the backends. It also allows us to possibly expose keyboard grab separately from mouse grab for applications that want to manage those independently.
Ethan Lee e787282b 2021-01-23T15:40:22 Implement Wayland_SetWindowResizable
Cameron Gutman bd553ea8 2021-01-20T21:17:20 Implement support for inhibiting the screensaver on Wayland We support both the org.freedesktop.ScreenSaver D-Bus API (same as the X11 backend) and the Wayland idle_inhibit_unstable_v1 protocol. Some Wayland compositors only support one or the other, so we need both to for broad compatibility.
Cameron Gutman 19236b46 2021-01-21T21:49:13 Implement support for minimizing windows on Wayland This required a bit of extra code to deal with the transition from minimized back to fullscreen
Cameron Gutman d789ba83 2021-01-19T18:20:07 Implement keyboard grab support for Wayland Use zwp_keyboard_shortcuts_inhibit_manager_v1 to allow SDL applications to capture system keyboard shortcuts like Alt+Tab when keyboard grab is enabled via SDL_HINT_GRAB_KEYBOARD.
Sam Lantinga 6a342954 2021-01-14T14:42:53 Fixed bug 5451 - Can't create EGLSurface in Wayland from SDLWindow (no EGLNativeWindow pointer) sashikknox In some cases, need create EGLWindow with SDLWindow. In X11 i can get pointer to NativeWindow from **struct SDL_SysWMinfo wmInfo** ```C++ struct SDL_SysWMinfo wmInfo; SDL_GetWindowWMInfo(ptSDLWindow, &wmInfo) #if defined(__unix__) && defined(SDL_VIDEO_DRIVER_X11) nativeWindow=(EGLNativeWindowType)wmInfo.info.x11.window; nativeDisplay=(EGLNativeDisplayType)wmInfo.info.x11.display; #endif ``` than i can create EGLSurface ``` eglCreateWindowSurface(nativeDisplay, EGL_CONFIG, nativeWindow, SURFACE_ATTRIBUTES); ``` in Wayland i can do it with same way, just need pointer to **EGLWindow**, we already have pointer to **wl_display** from **SDL_sysWMInfo**, need add to **wl** struct in SDL_SysWMInfo another pointer to **struct wl_egl_window *egl_window;**. And in wayland backend, in function **Wayland_GetWindowWMInfo** return pointer to **egl_window** from **SDL_WindowData** Now i use patched statically built SDL2 in port of Quake 2 GLES2 for SailfishOS (it use QtWayland): link to SDL2 commit and changed string for patch: - https://github.com/savegame/lp-public/commit/6858a618cd179b766fe3cab36055f07cb03ad0ea - https://github.com/savegame/lp-public/blob/b1e29e87b9d15780e47f04918b329ac15554fc69/SDL2/src/video/wayland/SDL_waylandwindow.c#L463 link to use in Quake2 port: 1. here i get pointer to EGLNativeWindowType: https://github.com/savegame/lp-public/blob/6d94fedb1b720da24999ae6286a1809cd3d55ff5/Engine/Sources/Compatibility/OpenGLES/EGLWrapper.c#L319 2. then use it for create EGLSurface: https://github.com/savegame/lp-public/blob/6d94fedb1b720da24999ae6286a1809cd3d55ff5/Engine/Sources/Compatibility/OpenGLES/EGLWrapper.c#L391

Sebastian Krzyszkowiak 48917e0e 2018-11-07T01:08:35 wayland: fix resizing and fullscreen toggling For starters, we need to correctly respond to 0,0 configure after unsetting fullscreen. Also, turns out that there should be no drawing calls at all in between eglSwapBuffers and wl_egl_window_resize, as otherwise EGL can already allocate a wrongly sized buffer for a next frame, so handle those together.

Right now we just match what the existing wl_shell code does, but there are other areas of functionality available to us now, that we can fill in later. This uses the "unstable" API, since this is what ships in Ubuntu 17.10 (as part of Wayland 1.10), but Wayland 1.12 promotes this to stable with extremely minor changes. We will add support for the stable version when it makes sense to do so.

Other platforms also have different sizes for the C union in question, but are likely the only target for that platform, etc. Apps that might run on Wayland or DirectFB will need to be compiled against new headers from an official 2.0.6 release, or be prepared to force the x11 target, or not use SDL_GetWindowWMInfo().

Thomas Perl acce8659 2016-11-13T10:39:04 [qtwayland] Set orientation and window flags via SDL hints
Sam Lantinga eea76fc1 2016-10-07T18:11:03 Fixed bug 3063 - Wayland: SDL resizes EGL surface to 0x0. x414e54 Wayland will sometimes send empty resize events (0 width and 0 height) to the client. I have not worked out the exact conditions a client would receive these but I can assume it might be if the window is offscreen or not mapped yet. This causes issues with some SDL clients as they receive the 0x0 event and unexpected resize event or might not request to resize back to the correct size. As per the wl_shell Wayland spec configure events are only a suggestion and the client is free to ignore or pick a different size (this is how min/max and fixed aspect ratio is supped to be implemented). A patch is attached but is just the first iteration and I will fix any issues such as checking for FULLSCREEN/MAXIMIZED or RESIZABLE flags unless someone else fixes this first. I have update to take into account non resizable and fullscreen windows. Also adding in maximize/restore and title functions for Wayland.
Sam Lantinga f11a4409 2016-09-01T01:26:56 wayland: Add support for relative mouse mode, by Jonas ?dahl <jadahl@gmail.com> Generate the C protocol files from the protocol XML files installed by wayland-protocols, and use them to implement support for relative pointer motions and pointer locking. Note that at the time, the protocol is unstable and may change in the future. Any future breaking changes will, however, fail gracefully and result in no regressions compared to before this patch.
Bastien Nocera 736a624d 2016-09-01T01:22:58 Wayland: Set "class" for each window we create This will be used by Wayland compositors to match the application ID and .desktop file to the SDL window(s). Applications can set the SDL_VIDEO_WAYLAND_WMCLASS environemnt variable early in the process to override using the binary name as a fallback. Note that we also support the SDL_VIDEO_X11_WMCLASS in the Wayland backend so that if a program correctly associated the desktop file with the window under X11, only a newer SDL would be needed for it to work under Wayland. https://bugzilla.libsdl.org/show_bug.cgi?id=3376
