b75cd2b3	2022-06-10T14:12:03	x11: Force window back to expected size after SDL_SetWindowBordered. This helps if the window manager decided to let it fill the space that an existing border was using before its removal. Fixes #5718.
412ceb84	2022-05-24T16:27:54	video: Only check major version in SDL_GetWindowWMInfo Since #5602, SDL is intended to have the same ABI across the whole major-version 2 cycle, so we should not check that the minor version matches the one that was used to compile an application. There are two checks that could make sense here. The first check is that the major version matches the expected major version. This is usually unnecessary and is not usually done (if we're calling into the wrong library we'll likely crash anyway), but since we have the information, we might as well continue to use it. The second check is whether the version provided by the caller is equal to or greater than a threshold version at which additional fields were added to the struct. If it is, we should populate those fields; if it is not, then we cannot. This is only useful on platforms where additional fields have genuinely been added during the lifetime of SDL 2, like Windows and DirectFB (but not X11). This commit changes the first check to be consistent about only looking at the minor version, while leaving the second check using SDL_VERSIONNUM (which will be removed or widened in SDL 3, but it's fine for now).

9edd411a	2022-05-19T17:15:10	x11: send move/resize events when waiting on fullscreen change. Otherwise we ignore the Configure/etc events when they come in because the window is already in an identical state as far as SDL is concerned. Fixes #5593. May also fix: Issue #5572. Issue #5595.

85977354	2022-04-07T09:14:33	x11: Treat WM setting the window "fullscreen" like FULLSCREEN_DESKTOP. Fixes #5390.
0249df9d	2022-04-05T23:04:19	x11: Try to keep SDL_WINDOW_FULLSCREEN* in sync with window manager. 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.
8bae343f	2022-04-05T22:19:25	x11: when waiting on fullscreen changes, not window position _and_ size. This makes sure the window doesn't have outdated values if you try to access them (or call something that does, like SDL_SetWindowMinimumSize).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.
a5672b85	2022-04-05T11:10:41	x11: Wait a bit to see if window pos changes when changing fullscreen. Helps prevent window from moving to 0,0 when leaving fullscreen. Fixes #4749.
7e15ad2f	2022-03-30T14:15:52	x11: Catch X11 errors in X11_SetWindowPosition and X11_SetWindowSize. The functions can go south if other operations are in progress, like X11_SetWindowBordered, which might be doing something traumatic behind the scenes of the window manager. We can't make these tasks totally synchronous, which would fix the problem, because not only can the window manager block however long it wants, it might also decide to deny our requests without any notification, so we'd be waiting forever for a window change that isn't coming. :( Fixes #5274.

f6fdbc1e	2021-11-29T21:16:15	video: x11: Fix an invalid SDL_LogError() call This fixes a compile warning — and possible invalid memory read — introduced in 9c03d255 ("Add back X11 legacy WM_NAME encodings"), which was part of PR #5029, fixing Bug #4924. The issue is with one of the added warnings in X11_GetWindowTitle(). Basically, the "title" variable passed to SDL_LogError() hasn't been initialised yet: we could pass propdata in directly, but it's better to move the SDL_LogError() call until after title is set, IMHO. This fixes the following warning from gcc (SUSE Linux) 11.2.1: In file included from /home/david/Development/SDL/src/video/x11/../../SDL_internal.h:45, from /home/david/Development/SDL/src/video/x11/SDL_x11window.c:21: /home/david/Development/SDL/src/video/x11/SDL_x11window.c: In function 'X11_GetWindowTitle': /home/david/Development/SDL/src/video/x11/../../dynapi/SDL_dynapi_overrides.h:33:22: warning: '%s' directive argument is null [-Wformat-overflow=] 33 \| #define SDL_LogDebug SDL_LogDebug_REAL /home/david/Development/SDL/src/video/x11/SDL_x11window.c:720:13: note: in expansion of macro 'SDL_LogDebug' 720 \| SDL_LogDebug(SDL_LOG_CATEGORY_VIDEO, "Failed to convert WM_NAME title expecting UTF8!

9c03d255	2021-11-28T16:18:39	Add back X11 legacy WM_NAME encodings Closes #4924. Based on patches of the past, such as this work by James Cloos in July 2010: https://github.com/exg/rxvt-unicode/commit/d7d98751b7385416ad1694b5f1fde6c312ba20d5, as well as code comments in the Perl module X11::Protocol::WM (https://metacpan.org/pod/X11::Protocol::WM) and even the code to Xlib itself, which taught me that we should never have been using `XStoreName`, all it does is call `XChangeProperty`, hardcoded to `XA_STRING`! What can I say, when the task is old school, the sources are too 😂

7d21322d	2021-11-08T16:29:19	Implemented SDL_SetWindowMouseRect() on Windows
4b42c05b	2021-11-08T13:52:48	video: Add SDL_SetWindowMouseRect. This API and implementation comes from the Unreal Engine branch of SDL, which originally called this "SDL_ConfineCursor". Some minor cleanup and changes for consistency with the rest of SDL_video, but there are two major changes: 1. The coordinate system has been changed so that `rect` is _window_ relative and not _screen_ relative, making it easier to implement without having global access to the display. 2. The UE version unset all rects when passing `NULL` as a parameter for `window`, this has been removed as it was an unused feature anyhow. Currently this is only implemented for X, but can be supported on Wayland and Windows at minimum too.

1f482174	2021-04-25T12:44:35	x11: Mark backing_store as NotUseful when creating windows. This can give some performance boost, and save some resources, as there's no reason to keep a copy of an SDL window's contents on the server: most SDL apps are redrawing completely every frame, and the API allows for expose events to tell an app a redraw is needed anyhow. (And compositors are free to ignore this setting if it makes sense to do so, according to the Xlib docs.) Reference Issue #3776.
9c063468	2021-04-24T19:47:10	x11: call XSync before XSetInputFocus during SDL_ShowWindow. This only happens when using a non-NET_WM window manager, as we might try to set the focus before the window is mapped. Fixes #3949.

6b057c67	2021-01-26T19:16:17	Expose separate keyboard and mouse grab support This adds SDL_SetWindowKeyboardGrab(), SDL_GetWindowKeyboardGrab(), SDL_SetWindowMouseGrab(), SDL_GetWindowMouseGrab(), and new SDL_WINDOW_KEYBOARD_GRABBED flag. It also updates the test harness to exercise this functionality and makes a minor fix to X11 that I missed in https://hg.libsdl.org/SDL/rev/02a2d609369b To fit in with this new support, SDL_WINDOW_INPUT_CAPTURE has been renamed to SDL_WINDOW_MOUSE_CAPTURE with the old name remaining as an alias for backwards compatibility with older code.

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.

d1df3437	2020-02-14T13:17:18	x11: SDL_SetWindowPosition should try to wait for the window manager. Wait up to 100 milliseconds, since the window manager might alter or outright veto the window change...or not respond at all. In a well-functioning system, though, this should help make sure that SDL_SetWindowPosition's results match reality. Fixes Bugzilla #4646.
4b585e75	2020-02-03T08:06:52	Fixed bug 4833 - Use EGL for X11? Martin Fiedler To be precise, this is about desktop OpenGL on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above. To shine some light on why this is needed: In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that requires the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.) Some example code: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation. The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX. I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

b1539c4c	2019-11-16T22:35:48	Fixed bug 4819 - Attempting to create an OpenGL ES context with unachievable MSAA parameters under X11 dooms the program Solra Bizna I have written a program that, in the event that the user requests more MSAA samples than their hardware supports, attempts to gracefully fall back to the best MSAA available. This code works with my conventional OpenGL renderer, but if I change nothing about the code except to make it request an OpenGL ES profile instead, Xlib kills the program with an error that looks like: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x5c00008 Serial number of failed request: 188 Current serial number in output stream: 193 To trigger the bug, attempt to create a window with the SDL_WINDOW_OPENGL flag, with SDL_GL_CONTEXT_PROFILE_MASK set to SDL_GL_CONTEXT_PROFILE_ES, and with SDL_GL_MULTISAMPLESAMPLES set to any unsupported value. SDL_CreateWindow properly returns NULL, but at this point the program is already doomed. Xlib will shortly terminate the program with an error. Calling SDL_CreateWindow again will immediately trigger this termination. I have attached a skeletal program that reproduces this bug for me. Replacing SDL_GL_CONTEXT_PROFILE_ES with SDL_GL_CONTEXT_PROFILE_COMPATIBILITY avoids the bug (but, obviously, doesn't create an OpenGL ES context). As I suspected, the problem was with XDestroyWindow being called twice on the same window. The X11_CreateWindow function in src/video/x11/SDL_x11window.c calls SetupWindowData. If initialization fails after that point, XDestroyWindow gets called on the window by a subsequent call to X11_DestroyWindow. But, later in the same function, iff a GLES context is requested and initializing it fails, X11_XDestroyWindow (which wraps XDestroyWindow) is manually called. Shortly after, the intended call to X11_DestroyWindow occurs, which attempts to destroy the same window again. Boom. (The above confusing summary involves three separate, similarly-named functions: XDestroyWindow, X11_DestroyWindow, X11_XDestroyWindow) I have attached a simple patch that removes the redundant X11_XDestroyWindow calls. I've tested that XDestroyWindow still gets called for the windows in question, and that it only gets called once.
c0255be4	2019-10-26T23:58:55	x11: check if the X server honored our XMoveWindow() call (thanks, R.E. Rust!). This can happen if a window is still grabbed when we try to move it, or if the X11 ecosystem is just in a bad mood, I guess. This makes sure that SDL will report the correct position for a window; otherwise, SDL_GetWindowPosition will just report whatever the last SDL_SetWindowPosition call requested, even if the window didn't actually move. Fixes Bugzilla #4646.

e061a92d	2018-08-02T16:03:47	Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.

f5a38f23	2017-08-21T00:42:06	x11: specify event mask for buttons when grabbing pointer (thanks, Stas!). This fixes a strange corner case (notes appended below), and should be safe to do anyhow. Fixes Bugzilla #3674. "I did more tests. It appears the bug only happens if there is another window on the screen that has "always on top" property. For me it is xawtv - it is always opened in a screen corner. Closing xawtv or removing "always on top" property from it makes the problem to go away. Plus, it doesn't appear like the buttons are not delivered at all. It appears that instead the button presses are delivered on some mouse positions, but not delivered when you move the mouse to other part of the window... So this is really weird and is likely somewhere deep in the Xorg. Maybe somehow it happens that the cursor is actually above the xawtv window, but, because my app uses grab, it is not visible there, and in that case the events are not delivered to my app? But with my patch the button events are always delivered flawlessly, it seems. Hmm, and that indeed seems to explain my problem: if the mask is set properly and my app uses grab, then, even if the mouse is above some other window, the events would still be delivered to the grabbing app, which is what actually wanted because my app uses relative mouse mode, so it doesn't know the pointer can cross some other window (my app draws the pointer itself). So my current theory is that my patch only enforces the mouse grab, which otherwise can be tricked by some other window preventing the button events delivery (but motion events are still delivered via xinput2, which makes it all look very obscure)."
362d5496	2017-08-14T10:28:47	Fixed bug 2500 - X11: SDL tries (and fails) to hide foreign windows Alvin I'm interested in this bug as well. I have experienced it when trying to embed an SDL_Window into a FLTK application. To do this, I create a FLTK window (window inside a window - think video player) and then use SDL_CreateWindowFrom() on the inner most window's Xlib Window. After which, I create a renderer. In my situation I am using the FLTK GUI toolkit. What I have experienced is that the SDL_CreateRender() will recreate the window in order to properly setup OpenGL capability. As part of this process, the window is hidden and a call is executed that waits indefinitely for an acknowledgement that the window was indeed unmapped. This is where my program hangs. Please correct me if I am wrong, but should SDL2 not make Xlib calls that effect the Xlib Window in this situation (e.g. When SDL_CreateWindowFrom() is used)? The toolkit being used typically assumes responsibility and, I presume, tracks all Xlib Windows it creates. On line src/video/SDL_video.c:1372 the comment associated with setting SDL_WINDOW_FOREIGN reads: / Can't destroy and re-create foreign windows, hrm / Since I do not know the reason for hiding the window in the first place, the attached patch simply does not wait for a response when X11_XWithdrawWindow() and X11_XMapRaised() are issued by X11_HideWindow() and X11_ShowWindow(), respectively. I presume that the GUI toolkit (GTK, FLTK, etc.) has or will consume the acknowledging event as it is managing the Xlib Window (or it thinks it is). I have tested the patch against hg 5c645d037de2 and I have successfully tested: Embedding the SDL_Window inside a FLTK application. * Calling SDL_SetWindowSize() when FLTK resizes the window (e.g. dragging cursor on the edge of the window). * Filling the renderer's default target blue and drawing a red fill square at the centre (exciting, I know!) * Calling SDL_Quit() when the application terminates I do not receive any Xlib erorr messages (BadWindow, etc.) in any of those situations.
177f19af	2017-07-20T10:52:43	Fixed bug 3410 - SDL_WINDOW_HIDDEN flag is inaccurate. Jason Wyatt After hiding the window, SDL_WINDOW_HIDDEN/SDL_WINDOW_SHOWN flags on a window are correctly updated. However on the next SDL_PumpEvents, they are set incorrectly. This appears to be because X11_GetNetWMState does not check whether the _NET_WM_STATE property exists (it shouldn't on unmapped windows, see https://specifications.freedesktop.org/wm-spec/wm-spec-1.3.html#idm140130317598336). This results in an empty list of atoms for the state, which would imply that the window is not hidden. (Seen on Fedora 24, Gnome) -- Dan Ginsburg More details on my proposed patch: I am on Kubuntu 16.04.2. I ran into this same bug, but with Jason's patch I found that actualType != None was true so the SDL_WINDOW_HIDDEN would still not be set. My fix instead is to explicitly check for whether the window is unmapped rather than relying on the returned values in XGetWindowProperty.

(For bug #2570) - Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum OpenGL ES version supported by the OpenGL driver (for bug #3145) - Modifies the test that determines whether to use the OpenGL driver or the real OpenGL ES driver to take into account the hint, the requested and supported ES version and whether ES 1.X is being requested. (For bug #2570 & bug #3145) - Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds the test to the VisualC projects.

02f49fdb	2016-03-04T18:47:19	x11: Deal with window borders better. - Cache the _NET_FRAME_EXTENTS data locally, so we don't have to query the X server for them (instead, we update our cached data when PropertyNotify events alert us to a change). - Use our cached extents for X11_GetWindowBordersSize(), so it's a fast call. - Window position was meant to refer to the client area, not the window decorations, so adjust appropriately when getting/setting the position.

45407d0e	2016-02-15T21:49:09	x11: Removed an assert. This assert triggers when run under XMonad. It's safe to pass a zero here anyhow, as this will still work "well enough" and the original problem--GNOME printing a warning message--is still fixed because GNOME's window manager gives us a chance to grab a non-zero user-time value before this code is run.

Unity's window manager is (legitimately, since it moves the client window's position) sending one, and SDL was incorrectly trying to mask it out. Other window managers (KWin, apparently) don't move the window and would hang here indefinitely. Fixes Bugzilla #3052.

0e45984f	2015-06-21T17:33:46	Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

video: Only check major version in SDL_GetWindowWMInfo Since #5602, SDL is intended to have the same ABI across the whole major-version 2 cycle, so we should not check that the minor version matches the one that was used to compile an application. There are two checks that could make sense here. The first check is that the major version matches the expected major version. This is usually unnecessary and is not usually done (if we're calling into the wrong library we'll likely crash anyway), but since we have the information, we might as well continue to use it. The second check is whether the version provided by the caller is equal to or greater than a threshold version at which additional fields were added to the struct. If it is, we should populate those fields; if it is not, then we cannot. This is only useful on platforms where additional fields have genuinely been added during the lifetime of SDL 2, like Windows and DirectFB (but not X11). This commit changes the first check to be consistent about only looking at the minor version, while leaving the second check using SDL_VERSIONNUM (which will be removed or widened in SDL 3, but it's fine for now).

video: x11: Fix an invalid SDL_LogError() call This fixes a compile warning — and possible invalid memory read — introduced in 9c03d255 ("Add back X11 legacy WM_NAME encodings"), which was part of PR #5029, fixing Bug #4924. The issue is with one of the added warnings in X11_GetWindowTitle(). Basically, the "title" variable passed to SDL_LogError() hasn't been initialised yet: we could pass propdata in directly, but it's better to move the SDL_LogError() call until after title is set, IMHO. This fixes the following warning from gcc (SUSE Linux) 11.2.1: In file included from /home/david/Development/SDL/src/video/x11/../../SDL_internal.h:45, from /home/david/Development/SDL/src/video/x11/SDL_x11window.c:21: /home/david/Development/SDL/src/video/x11/SDL_x11window.c: In function 'X11_GetWindowTitle': /home/david/Development/SDL/src/video/x11/../../dynapi/SDL_dynapi_overrides.h:33:22: warning: '%s' directive argument is null [-Wformat-overflow=] 33 | #define SDL_LogDebug SDL_LogDebug_REAL /home/david/Development/SDL/src/video/x11/SDL_x11window.c:720:13: note: in expansion of macro 'SDL_LogDebug' 720 | SDL_LogDebug(SDL_LOG_CATEGORY_VIDEO, "Failed to convert WM_NAME title expecting UTF8!

2021-11-08T13:52:48

video: Add SDL_SetWindowMouseRect. This API and implementation comes from the Unreal Engine branch of SDL, which originally called this "SDL_ConfineCursor". Some minor cleanup and changes for consistency with the rest of SDL_video, but there are two major changes: 1. The coordinate system has been changed so that `rect` is _window_ relative and not _screen_ relative, making it easier to implement without having global access to the display. 2. The UE version unset all rects when passing `NULL` as a parameter for `window`, this has been removed as it was an unused feature anyhow. Currently this is only implemented for X, but can be supported on Wayland and Windows at minimum too.

Fixed bug 4833 - Use EGL for X11? Martin Fiedler To be precise, this is about *desktop OpenGL* on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above. To shine some light on why this is needed: In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that *requires* the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.) Some example code: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation. The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX. I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

Fixed bug 4819 - Attempting to create an OpenGL ES context with unachievable MSAA parameters under X11 dooms the program Solra Bizna I have written a program that, in the event that the user requests more MSAA samples than their hardware supports, attempts to gracefully fall back to the best MSAA available. This code works with my conventional OpenGL renderer, but if I change nothing about the code except to make it request an OpenGL ES profile instead, Xlib kills the program with an error that looks like: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x5c00008 Serial number of failed request: 188 Current serial number in output stream: 193 To trigger the bug, attempt to create a window with the SDL_WINDOW_OPENGL flag, with SDL_GL_CONTEXT_PROFILE_MASK set to SDL_GL_CONTEXT_PROFILE_ES, and with SDL_GL_MULTISAMPLESAMPLES set to any unsupported value. SDL_CreateWindow properly returns NULL, but at this point the program is already doomed. Xlib will shortly terminate the program with an error. Calling SDL_CreateWindow again will immediately trigger this termination. I have attached a skeletal program that reproduces this bug for me. Replacing SDL_GL_CONTEXT_PROFILE_ES with SDL_GL_CONTEXT_PROFILE_COMPATIBILITY avoids the bug (but, obviously, doesn't create an OpenGL ES context). As I suspected, the problem was with XDestroyWindow being called twice on the same window. The X11_CreateWindow function in src/video/x11/SDL_x11window.c calls SetupWindowData. If initialization fails after that point, XDestroyWindow gets called on the window by a subsequent call to X11_DestroyWindow. But, later in the same function, iff a GLES context is requested and initializing it fails, X11_XDestroyWindow (which wraps XDestroyWindow) is manually called. Shortly after, the intended call to X11_DestroyWindow occurs, which attempts to destroy the same window again. Boom. (The above confusing summary involves three separate, similarly-named functions: XDestroyWindow, X11_DestroyWindow, X11_XDestroyWindow) I have attached a simple patch that removes the redundant X11_XDestroyWindow calls. I've tested that XDestroyWindow still gets called for the windows in question, and that it only gets called once.

This makes sure that SDL will report the correct position for a window; otherwise, SDL_GetWindowPosition will just report whatever the last SDL_SetWindowPosition call requested, even if the window didn't actually move. Fixes Bugzilla #4646.

Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.

Fixed bug 4085 - X11: Allow configuring _NET_WM_BYPASS_COMPOSITOR through SDL hints Callum McGing This patch allows the user to disable the behaviour that blocks the compositor through a new hint: SDL_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR. This allows tools or other windowed applications to behave properly under KWin.

x11: specify event mask for buttons when grabbing pointer (thanks, Stas!). This fixes a strange corner case (notes appended below), and should be safe to do anyhow. Fixes Bugzilla #3674. "I did more tests. It appears the bug only happens if there is another window on the screen that has "always on top" property. For me it is xawtv - it is always opened in a screen corner. Closing xawtv or removing "always on top" property from it makes the problem to go away. Plus, it doesn't appear like the buttons are not delivered at all. It appears that instead the button presses are delivered on some mouse positions, but not delivered when you move the mouse to other part of the window... So this is really weird and is likely somewhere deep in the Xorg. Maybe somehow it happens that the cursor is actually above the xawtv window, but, because my app uses grab, it is not visible there, and in that case the events are not delivered to my app? But with my patch the button events are always delivered flawlessly, it seems. Hmm, and that indeed seems to explain my problem: if the mask is set properly and my app uses grab, then, even if the mouse is above some other window, the events would still be delivered to the grabbing app, which is what actually wanted because my app uses relative mouse mode, so it doesn't know the pointer can cross some other window (my app draws the pointer itself). So my current theory is that my patch only enforces the mouse grab, which otherwise can be tricked by some other window preventing the button events delivery (but motion events are still delivered via xinput2, which makes it all look very obscure)."

Fixed bug 2500 - X11: SDL tries (and fails) to hide foreign windows Alvin I'm interested in this bug as well. I have experienced it when trying to embed an SDL_Window into a FLTK application. To do this, I create a FLTK window (window inside a window - think video player) and then use SDL_CreateWindowFrom() on the inner most window's Xlib Window*. After which, I create a renderer. In my situation I am using the FLTK GUI toolkit. What I have experienced is that the SDL_CreateRender() will recreate the window in order to properly setup OpenGL capability. As part of this process, the window is hidden and a call is executed that waits indefinitely for an acknowledgement that the window was indeed unmapped. This is where my program hangs. Please correct me if I am wrong, but should SDL2 not make Xlib calls that effect the Xlib Window in this situation (e.g. When SDL_CreateWindowFrom() is used)? The toolkit being used typically assumes responsibility and, I presume, tracks all Xlib Windows it creates. On line src/video/SDL_video.c:1372 the comment associated with setting SDL_WINDOW_FOREIGN reads: /* Can't destroy and re-create foreign windows, hrm */ Since I do not know the reason for hiding the window in the first place, the attached patch simply does not wait for a response when X11_XWithdrawWindow() and X11_XMapRaised() are issued by X11_HideWindow() and X11_ShowWindow(), respectively. I presume that the GUI toolkit (GTK, FLTK, etc.) has or will consume the acknowledging event as it is managing the Xlib Window (or it thinks it is). I have tested the patch against hg 5c645d037de2 and I have successfully tested: * Embedding the SDL_Window inside a FLTK application. * Calling SDL_SetWindowSize() when FLTK resizes the window (e.g. dragging cursor on the edge of the window). * Filling the renderer's default target blue and drawing a red fill square at the centre (exciting, I know!) * Calling SDL_Quit() when the application terminates I do not receive any Xlib erorr messages (BadWindow, etc.) in any of those situations.

Fixed bug 3410 - SDL_WINDOW_HIDDEN flag is inaccurate. Jason Wyatt After hiding the window, SDL_WINDOW_HIDDEN/SDL_WINDOW_SHOWN flags on a window are correctly updated. However on the next SDL_PumpEvents, they are set incorrectly. This appears to be because X11_GetNetWMState does not check whether the _NET_WM_STATE property exists (it shouldn't on unmapped windows, see https://specifications.freedesktop.org/wm-spec/wm-spec-1.3.html#idm140130317598336). This results in an empty list of atoms for the state, which would imply that the window is not hidden. (Seen on Fedora 24, Gnome) -- Dan Ginsburg More details on my proposed patch: I am on Kubuntu 16.04.2. I ran into this same bug, but with Jason's patch I found that actualType != None was true so the SDL_WINDOW_HIDDEN would still not be set. My fix instead is to explicitly check for whether the window is unmapped rather than relying on the returned values in XGetWindowProperty.

Fixed bugs 2570, 3145, improved OpenGL ES context support on Windows and X11 Mark Callow The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile: - Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can say to use the OpenGL ES driver & EGL rather than the Open GL driver. (For bug #2570) - Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum OpenGL ES version supported by the OpenGL driver (for bug #3145) - Modifies the test that determines whether to use the OpenGL driver or the real OpenGL ES driver to take into account the hint, the requested and supported ES version and whether ES 1.X is being requested. (For bug #2570 & bug #3145) - Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds the test to the VisualC projects. With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.

x11: Deal with window borders better. - Cache the _NET_FRAME_EXTENTS data locally, so we don't have to query the X server for them (instead, we update our cached data when PropertyNotify events alert us to a change). - Use our cached extents for X11_GetWindowBordersSize(), so it's a fast call. - Window position was meant to refer to the client area, not the window decorations, so adjust appropriately when getting/setting the position.

Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().
