Eric Wasylishen ab81a559 2022-06-07T02:01:27 Windows DPI scaling/highdpi support Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to change the SDL coordinate system units to be DPI-scaled points, rather than pixels everywhere. This means windows will be appropriately sized, even when created on high-DPI displays with scaling. e.g. requesting a 640x480 window from SDL, on a display with 125% scaling in Windows display settings, will create a window with an 800x600 client area (in pixels). Setting this to "1" implicitly requests process DPI awareness (setting SDL_WINDOWS_DPI_AWARENESS is unnecessary), and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.

Sam Lantinga b9cbea35 2020-10-13T21:08:20 video: Refresh Windows display list on WM_DISPLAYCHANGE - Displays may have been added, removed or changed and all cached monitor handles are invalidated as a result. - Display events are handled in three steps: 1. Mark all currently know displays as invalid 2. Enumerate all displays, adding new ones and marking known displays as valid 3. Remove all displays still invalid after enumeration - Display connect/disconnect events are sent when displays are added or removed after initial setup

Sam Lantinga 6e1b11ba 2017-08-11T10:18:45 Fixed bug 3714 - Windows: SDL_WINDOW_FULLSCREEN_DESKTOP broken on 3 monitor setup w/ DPI scaling Eric Wasylishen 2017-07-26 18:42:58 UTC I set up an (admittedly exotic) 3-monitor setup, and when I enter fullscreen-desktop on the middle display (#2), the SDL window is off center. (covers half of monitor #2 and most of monitor #3). The displays are arranged from left to right: Display #1 (main): 2880x1800, 200% scaling Display #2: 1920x1200, 150% scaling Display #3: 1920x1080, 100% scaling SDL display bounds: INFO: Bounds: 1440x900 at 0,0 INFO: Bounds: 1281x801 at 1921,0 (these are incorrect) INFO: Bounds: 1920x1080 at 4800,0 Correct bounds reported by calling EnumDisplayMonitors and printing the LPRECT param of the callback: 1440x900 at (0, 0) 1280x800 at (2880, 0) 1920x1080 at (4800, 0) It seems like you need 3 displays to reproduce this, and the left two need DPI scaling, and the 3rd display needs to have a different scale factor than the others. Related: https://bugzilla.libsdl.org/show_bug.cgi?id=3709 SDL: current hg (11235:6a587b9e0ec8) Windows 10, Version 10.0.15063 Build 15063 Tested with testdraw2 and testgl2, and pressing alt+enter to enter fullscreen desktop. This patch reworks SDL_windowsmodes.c to use EnumDisplayMonitors instead of EnumDisplayDevices, so we always have an HMONITOR for each SDL display. With access to an HMONITOR, we can get the monitor bounds in virtual screen coordinates the proper way, by calling GetMonitorInfo. (whereas the original code was doing some calculations - e.g. "data->DeviceMode.dmPosition.x * data->ScaleX" - to try to get virtual screen coordinates. These worked in simple cases, but failed in more complex cases like this bug) The one potential problem with my patch is, the ChangeDisplaySettingsEx docs say that you're supposed to get the display name from EnumDisplayDevices, but I'm getting the display name from GetMonitorInfo now.

Alfred Reynolds 61c74150 2015-07-29T17:18:56 Add SDL_GetDisplayDPI routine and implement for Windows.
Philipp Wiesemann 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().

Ryan C. Gordon b72938c8 2015-04-20T12:22:44 Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.
Alex Szpakowski fe6c797c 2015-04-10T23:30:31 Fixed an iOS view orientation issue when SDL_GL_CreateContext or SDL_CreateRenderer is called.
Edward Rudd b88ca1b4 2015-02-10T16:28:56 the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
Philipp Wiesemann b48e54aa 2015-01-26T22:00:29 Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
David Ludwig 70438be2 2014-12-03T10:55:23 WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!

Pierre-Loup A. Griffais 24c86b55 2014-09-11T19:24:42 [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam

Sam Lantinga 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Sam Lantinga b44e7470 2013-12-30T12:49:15 Fixed display mode calculations for applications which are not DPI aware. If your application wants to have access to the full resolution even when the system has DPI scaling enabled, call SetProcessDPIAware() before calling SDL_Init() e.g. typedef BOOL (WINAPI *SetProcessDPIAware_t)(void); HMODULE hMod = LoadLibrary("user32.dll"); if ( hMod ) { SetProcessDPIAware_t pSetProcessDPIAware = GetProcAddress( hMod, "SetProcessDPIAware" ); if ( pSetProcessDPIAware ) { pSetProcessDPIAware(); } FreeLibrary( hMod ); }
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
Ryan C. Gordon 7e1289af 2013-11-24T23:56:17 Make internal SDL sources include SDL_internal.h instead of SDL_config.h The new header will include SDL_config.h, but allows for other global stuff.
Gabriel Jacobo dad42067 2013-08-12T11:13:50 Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
Sam Lantinga 1ad936eb 2013-08-11T19:56:43 Fixed bug 2027 - Full-screen appears to be broken - hang in SDL_DestroyWindow() Rainer Deyke I'm running Linux Mint 15 with the Cinnamon window manager. SDL_DestroyWindow consistently locks up for me when the window if fullscreen.
