Sam Lantinga 7cf76ffb 2013-11-11T21:21:18 Fixed assertion failure when minimizing a fullscreen window.
Sam Lantinga 75a23d99 2013-11-11T20:51:19 Fixed bug 2212 - SDL_SetTextInputRect has no effect on iOS philhassey Overview: While SDL_SetTextInputRect works perfectly to move my window out of the way of the virtual keyboard using SDL2/Android, on iOS this function has no effect. Steps to Reproduce: Call SDL_SetTextInputRect with a rect near the bottom of the screen before calling SDL_StartTextInput. Actual Results: The iOS virtual keyboard is displayed after calling SDL_StartTextInput, but the screen is not shifted to reveal the TextInputRect region. Expected Results: The screen should be shifted to reveal the TextInputRect region (like with SDL2/Android.) This patch implements SDL_SetTextInputRect for uikit/iOS. It sets up notification handlers to respond to changes in the display of the keyboard. These handlers then change the frame of the view so it is moved out of the way of the keyboard as per SetTextInputRect.

Sam Lantinga 2ceeb74e 2013-11-11T03:02:42 Don't minimize by default when in fullscreen desktop mode. This fixes behavior with the new Mac OS X fullscreen space code, as well as improve behavior on Linux desktops. The default for normal fullscreen mode is still to minimize because we're likely doing a mode switch and don't want to stick around as a borderless window in the background.

Sam Lantinga 976c8769 2013-11-08T14:05:23 Fixed bug 2172 - Window loses maximized state when activated I still haven't figured out why my application is being minimized when I try to raise, it but my previous workaround is causing issues. For now the correct way to raise and/or restore the window is as follows: if ( !(SDL_GetWindowFlags( window ) & SDL_WINDOW_MINIMIZED) ) { SDL_RaiseWindow( window ); } if ( SDL_GetWindowFlags( window ) & SDL_WINDOW_MINIMIZED ) { SDL_RestoreWindow( window ); } I will investigate the window state change rules more fully in the future.

Sam Lantinga 3523b409 2013-11-08T14:05:15 Made helper window creation depend on initializing the Haptics or Joystick subsystems.
Sam Lantinga faebe94c 2013-11-08T14:05:08 Mac: Fix a crash with SDL_MAC_NO_SANDBOX. When we get a kCGEventTapDisabledByTimeout or kCGEventTapDisabledByUserInput, the event tap would perform an invalid memory access. void pointers are so fun. This code only runs if you explicitly build with SDL_MAC_NO_SANDBOX.
Sam Lantinga e3e24bde 2013-11-08T14:04:59 Make sure the joystick count is correct when the added and removed events are dispatched, in case someone is watching for them with an event filter.

Sam Lantinga 493fadd5 2013-11-08T14:04:35 Fixed spot where SDL was assuming that two displays having the same origin means they're the same display. Changed it to check for the same extents instead. (Sam actually wrote this, I'm just reviewing and checking it in.)
Sam Lantinga 95c67ed9 2013-11-07T19:15:58 Fixed bug 2219 - BMP loader do not handle big BITMAPINFOHEADER structure Patrice Mandin I encountered a problem trying to load a 8-bit paletted BMP file using SDL. This file was generated using GIMP 2.8. It has a big BITMAPINFOHEADER (0x6c bytes for biSize field), and thus the palette is incorrectly setup.
Sam Lantinga 48e44f7f 2013-11-06T23:59:24 Fixed Windows compile error
Sam Lantinga 3b050fc9 2013-11-06T23:35:08 Horizontal wheel support in windows Lorenzo Pistone this patch adds support for the horizontal wheel in Windows. It is shamelessly copied off the vertical wheel code, but I guess that that is a value added in consistency.
Gabriel Jacobo 22770a8f 2013-11-06T11:23:24 [Android] Fixes Bug 2041 - can't get SDL_QUIT event... Thanks to Denis Bernard! Also, changed the Android manifest so the app doesn't quit with orientation changes, and made testgles.c exit properly on Android.

Gabriel Jacobo 0b7c69fe 2013-11-05T20:07:39 Adds Joystick support for Android This bumps the build SDK level to 12 (up from 10). Runtime requirements remain the same (at API level < 12 joystick support is disabled). Also enables building SDL for armv7 and x86.
Sam Lantinga 517886a7 2013-11-03T11:13:06 Fixed bug 2205 - SDL_GetAudioDeviceName returns default-device name on invalid index for default-device only drivers norfanin The audio_enumerateAndNameAudioDevicesNegativeTests test in testautomation_audio.c reports a failure for SDL_GetAudioDeviceName when called on a driver that has only the default device. SDL_GetNumAudioDevices reports 1, but SDL_GetAudioDeviceName does not check if the index passed by the caller is in that range in this case. For positive numbers anyway. This can be reproduced with the dummy driver on Windows and Linux.
Sam Lantinga f2224e1f 2013-11-03T09:55:27 Fixed bug 1990 - focus/keyboard events not generated correctly for multiple windows Mai Lavelle I've recently tried to create multiple windows and process key events for them, and found that key events weren't being generated for most of the windows. After some investigating I've observed the following effects. All but the most recently created window experience these effects... - a focus lost event is generated immediately after the focus gained event, even tho window still has focus - key events report window id 0 rather than the id of the window which has focus, SDL thinks no window has focus? - giving focus to a non SDL window and then selecting an SDL window causes events to be generated as expected, but only until focus changes again Focus change events are queued and delayed (200 ticks) before they are dispatched. The problem occurs when a focus out and focus in event are received on the same tick. When these delayed events are dispatched they will be sent in the order determined by the window list rather than the order in which they are received. The focus out dispatch is implemented by calling SDL_SetKeyboardFocus(NULL). This will remove focus from any window, regardless of whether it is the one originally targeted by the X11 event. Since SDL_SetKeyboardFocus() will always dispatch a focus lost event as needed, the easiest solution is simply to only call SDL_SetKeyboardFocus(NULL) when SDL_GetKeyboardFocus() matches the target window.

Sam Lantinga bcf5472d 2013-10-21T02:37:03 Fixed bug 2073 - Mac: window moves unexpectedly when exiting SDL_WINDOW_FULLSCREEN_DESKTOP mode Alex Szpakowski In Mac OS X, when SDL_SetWindowFullscreen(window, 0) is called on a window which was in SDL_WINDOW_FULLSCREEN_DESKTOP mode, its original size is restored but its position is moved to the bottom of the screen. I tracked down the issue to these two lines: http://hg.libsdl.org/SDL/file/fdd5cc9e9f90/src/video/cocoa/SDL_cocoawindow.m#l1034 I believe [nswindow setFrameOrigin:rect.origin] implicitly calls [nswindow constrainFrameRect:rect toScreen:screen], which will attempt to constrain the window to the screen, but at that point the window size is still full-screen rather than the restored window size, so the constrainFrameRect function operates on the wrong window size. https://developer.apple.com/library/mac/documentation/cocoa/reference/applicationkit/classes/NSWindow_Class/Reference/Reference.html#//apple_ref/occ/instm/NSWindow/constrainFrameRect:toScreen: I resolved the issue by swapping the order of the function calls, like so: [nswindow setContentSize:rect.size]; [nswindow setFrameOrigin:rect.origin];

Sam Lantinga 80930559 2013-10-21T00:25:43 Fixed bug 2012 - Algorithm logic getting wrong in ComputeOutCode Nitz I was going through the SDL_IntersectRectAndLine function and wondered to see the ComputeOutCode function implementation. The problem in this algo is, x and y axis are getting check with respect to 0, Which is wrong, it should be get checked with respect to rectangle x and y axis.
Sam Lantinga deb8086b 2013-10-21T00:20:27 Fixed bug 2072 - Make OS X's filesystem calls use -[NSString fileSystemRepresentation] C.W.

Sam Lantinga 08fa8da7 2013-10-20T21:56:15 Fixed bug 2129 - fix for bug 2121 breaks linking for mingw and throws multiple warnings Andreas Ertelt The problem in question is caused by changeset 7771 (http://hg.libsdl.org/SDL/rev/5486e579872e / https://bugzilla.libsdl.org/show_bug.cgi?id=2121) The redefinition of __inline__ (introduced by the addition of begin_code.h:128's "|| __STRICT_ANSI__") results in mingw's gcc throwing multiple warning: always_inline function might not be inlinable [-Wattributes] as well as a whole bunch of redefinitions of mingw internals which break linking of projects including the SDL2 headers.

Sam Lantinga 82b8e6df 2013-10-20T10:10:14 Fixed bug 2158 - Pixel missing in SDL_RenderDrawLines Sean McKean I am running Ubuntu 12.04 (GL version 1.4 Mesa 8.0.4) , and on drawing a set of lines through the renderer through SDL_RenderDrawLines() (looped or not) or SDL_RenderDrawRect() I notice a pixel missing. For RenderDrawLines() it seems to be the second point in the sequence; for RenderDrawRect() it is the lower-right. This can be fixed by specifying SDL_RenderDrawPoint(s), but wouldn't it be easier to specify each pixel in a GL_POINTS glBegin/End loop in the OpenGL code, just to make sure? I also ran the same program on Android; the rendering seemed to be correct, which uses glDrawArrays.

Sam Lantinga e343273a 2013-10-19T01:29:23 Fixed bug 2162 - SDL_RenderClear not clearing entire render target Kevin Wells Overview: SDL_RenderClear is only clearing part of a texture when it is the render target and a different size than the screen. Steps to Reproduce: 1) This only occurs with the render driver set to direct3d, so: SDL_SetHint(SDL_HINT_RENDER_DRIVER,"direct3d") Also, my window was 1280x720. 2) Create a texture for a render target with a resolution of 1024x1024: texture=SDL_CreateTexture(main_window.renderer,SDL_PIXELFORMAT_RGBA8888,SDL_TEXTUREACCESS_TARGET,1024,1024); SDL_SetTextureBlendMode(texture,SDL_BLENDMODE_BLEND); 3) Target the texture for rendering: SDL_SetRenderTarget(main_window.renderer,texture); 4) Set the draw color to whatever you want (problem occurs with both 0,0,0,0 and 0,0,0,255 among others) and then clear the render target: SDL_SetRenderDrawColor(main_window.renderer,0,0,0,0); SDL_RenderClear(main_window.renderer); Actual Results: Only about the top 3/4s of the texture gets cleared on calling SDL_RenderClear. The bottom 1/4 or so does not clear. Expected Results: Entire render target should be cleared.
Ryan C. Gordon b4a00144 2013-10-18T10:56:45 Fixed the XInput2 X11 symbols.

Sam Lantinga a329c7f1 2013-10-18T00:13:51 Fixed bug 2139 - SDL_CreateWindow/WIN_GL_LoadLibrary fails due to external iconv not being able to convert path J?nis R?cis Brief history: We recently ported a game from SDL 1.2 to SDL 2. While doing Windows testing, I soon discovered that the game exits without opening a window with my cross-compiled SDL2.dll, but works great with the SDL2.dll from the MinGW SDK on libsdl.org. It was as simple as swapping out the DLLs to make it work. Running the game in Wine showed that the game actually does run, up until the call to SDL_CreateWindow, which fails and leads the game to print out an error: Failure to create window (LoadLibrary("OPENGL32.DLL"): (null)) Which basically says that there was no error, but maybe that's a Wine quirk. The error string originates in SDL_windowsopengl.c, in WIN_GL_LoadLibrary, which contains this piece of code: wpath = WIN_UTF8ToString(path); _this->gl_config.dll_handle = LoadLibrary(wpath); SDL_free(wpath); if (!_this->gl_config.dll_handle) { char message[1024]; SDL_snprintf(message, SDL_arraysize(message), "LoadLibrary(\"%s\")", path); return WIN_SetError(message); } After some digging, I discovered the culprit: WIN_UTF8ToString returns NULL. Why? Because it calls iconv_open from an iconv.dll that does not support the UCS-2-INTERNAL encoding. Why does the official SDL2.dll work? Because it calls no external iconv functions at all. It turns out that the Fedora MinGW infrastructure (from which I obtained the conventiently prebuilt iconv.dll) does not provide a DLL from libiconv, but instead provides a DLL from a minimal Windows library called win-iconv. Which knows a good bit, but doesn't know anything about UCS-2-INTERNAL: http://code.google.com/p/win-iconv/source/browse/trunk/win_iconv.c#155 So there are two problems here: 1) The error message is clearly useless, because LoadLibrary is an innocent bystander. Instead wpath should probably checked for NULL, and a more appropriate error should be set. Ideally something that makes it clear than an external iconv is causing trouble. 2) SDL doomed itself at the ./configure step, by finding an existing iconv and happily using it without confirming support for the mandatory encodings required by SDL. There are certainly a few easy ways out of the situation (although I didn't yet manage to figure out how to prevent ./configure from looking for external iconv), but this had me completely stomped for a good while, so I figured it's worth writing down if anything. (Search also found this, which talks a little about using UTF-16LE instead of UCS-2-INTERNAL: https://bugzilla.libsdl.org/show_bug.cgi?id=2075)
Sam Lantinga 7ad441a3 2013-10-17T23:40:13 Fixed bug 2069 - Device addition/removal queries all USB devices rather than only HID devices. Andreas Ertelt SDL_dxjoystick.c is setting the classguid for device (dis)connect events to USB Devices in general: dbh.dbcc_classguid = GUID_DEVINTERFACE_USB_DEVICE; Wouldn't it make more sense to have it just subscribe to Hid device events? This would mean less meaningless events reaching the application.
