Disable the XRandR extension by default, since KDE maximizes windows which are larger than the new resolution, and then doesn't restore their size and positition when the old resolution is restored.
The extension can be enabled with the environment variable SDL_VIDEO_X11_XRANDR=1

| 0 | 38 1.2.0: |
| 39 Added SDL_VIDEOEXPOSE event to signal that the screen needs to | |
| 40 be redrawn. This is currently only delivered to OpenGL windows | |
| 41 on X11, though it may be delivered in the future when the video | |
| 42 memory is lost under DirectX. | |
| 43 | |
| 44 1.1.8: | |
| 45 You can pass SDL_NOFRAME to SDL_VideoMode() to create a window | |
| 46 that has no title bar or frame decoration. Fullscreen video | |
| 47 modes automatically have this flag set. | |
| 48 | |
| 49 Added a function to query the clipping rectangle for a surface: | |
| 50 void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 51 | |
| 52 Added a function to query the current event filter: | |
| 53 SDL_EventFilter SDL_GetEventFilter(void) | |
| 54 | |
| 55 If you pass -1 to SDL_ShowCursor(), it won't change the current | |
| 56 cursor visibility state, but will still return it. | |
| 57 | |
| 58 SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning | |
| 59 you can nest them as deep as you want, as long as each lock call | |
| 60 has a matching unlock call. The surface remains locked until the | |
| 61 last matching unlock call. | |
| 62 | |
| 63 Note that you may not blit to or from a locked surface. | |
| 64 | |
| 65 1.1.7: | |
| 66 The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take | |
| 67 arrays of Uint16 values instead of Uint8 values. For the most part, | |
| 68 you can just take your old values and shift them up 8 bits to get | |
| 69 new correct values for your gamma ramps. | |
| 70 | |
| 71 You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface() | |
| 72 and SDL will try to RLE accelerate colorkey and alpha blits in the | |
| 73 resulting surface. | |
| 74 | |
| 75 1.1.6: | |
| 76 Added a function to return the thread ID of a specific thread: | |
| 77 Uint32 SDL_GetThreadID(SDL_Thread *thread) | |
| 78 If 'thread' is NULL, this function returns the id for this thread. | |
| 79 | |
| 80 1.1.5: | |
| 81 The YUV overlay structure has been changed to use an array of | |
| 82 pitches and pixels representing the planes of a YUV image, to | |
| 83 better enable hardware acceleration. The YV12 and IYUV formats | |
| 84 each have three planes, corresponding to the Y, U, and V portions | |
| 85 of the image, while packed pixel YUV formats just have one plane. | |
| 86 | |
| 87 For palettized mode (8bpp), the screen colormap is now split in | |
| 88 a physical and a logical palette. The physical palette determines | |
| 89 what colours the screen pixels will get when displayed, and the | |
| 90 logical palette controls the mapping from blits to/from the screen. | |
| 91 A new function, SDL_SetPalette() has been added to change | |
| 92 logical and physical palettes separately. SDL_SetColors() works | |
| 93 just as before, and is equivalent to calling SDL_SetPalette() with | |
| 94 a flag argument of (SDL_LOGPAL|SDL_PHYSPAL). | |
| 95 | |
| 96 SDL_BlitSurface() no longer modifies the source rectangle, only the | |
| 97 destination rectangle. The width/height members of the destination | |
| 98 rectangle are ignored, only the position is used. | |
| 99 | |
| 100 The old source clipping function SDL_SetClipping() has been replaced | |
| 101 with a more useful function to set the destination clipping rectangle: | |
| 102 SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 103 | |
| 104 Added a function to see what subsystems have been initialized: | |
| 105 Uint32 SDL_WasInit(Uint32 flags) | |
| 106 | |
| 107 The Big Alpha Flip: SDL now treats alpha as opacity like everybody | |
| 108 else, and not as transparency: | |
| 109 | |
| 110 A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255 | |
| 111 A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0 | |
| 112 Values between 0 and 255 vary from fully transparent to fully opaque. | |
| 113 | |
| 114 New functions: | |
| 115 SDL_DisplayFormatAlpha() | |
| 116 Returns a surface converted to a format with alpha-channel | |
| 117 that can be blit efficiently to the screen. (In other words, | |
| 118 like SDL_DisplayFormat() but the resulting surface has | |
| 119 an alpha channel.) This is useful for surfaces with alpha. | |
| 120 SDL_MapRGBA() | |
| 121 Works as SDL_MapRGB() but takes an additional alpha parameter. | |
| 122 SDL_GetRGBA() | |
| 123 Works as SDL_GetRGB() but also returns the alpha value | |
| 124 (SDL_ALPHA_OPAQUE for formats without an alpha channel) | |
| 125 | |
| 126 Both SDL_GetRGB() and SDL_GetRGBA() now always return values in | |
| 127 the [0..255] interval. Previously, SDL_GetRGB() would return | |
| 128 (0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format. | |
| 129 (N.B.: This is broken for bit fields < 3 bits.) | |
| 130 | |
| 131 SDL_MapRGB() returns pixels in which the alpha channel is set opaque. | |
| 132 | |
| 133 SDL_SetAlpha() can now be used for both setting the per-surface | |
| 134 alpha, using the new way of thinking of alpha, and also to enable | |
| 135 and disable per-pixel alpha blending for surfaces with an alpha | |
| 136 channel: | |
| 137 To disable alpha blending: | |
| 138 SDL_SetAlpha(surface, 0, 0); | |
| 139 To re-enable alpha blending: | |
| 140 SDL_SetAlpha(surface, SDL_SRCALPHA, 0); | |
| 141 Surfaces with an alpha channel have blending enabled by default. | |
| 142 | |
| 143 SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests | |
| 144 RLE acceleration of blits, just as like with SDL_SetColorKey(). | |
| 145 This flag can be set for both surfaces with an alpha channel | |
| 146 and surfaces with an alpha value set by SDL_SetAlpha(). | |
| 147 As always, RLE surfaces must be locked before pixel access is | |
| 148 allowed, and unlocked before any other SDL operations are done | |
| 149 on it. | |
| 150 | |
| 151 The blit semantics for surfaces with and without alpha and colorkey | |
| 152 have now been defined: | |
| 153 | |
| 154 RGBA->RGB: | |
| 155 SDL_SRCALPHA set: | |
| 156 alpha-blend (using alpha-channel). | |
| 157 SDL_SRCCOLORKEY ignored. | |
| 158 SDL_SRCALPHA not set: | |
| 159 copy RGB. | |
| 160 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 161 RGB values of the source colour key, ignoring alpha in the | |
| 162 comparison. | |
| 163 | |
| 164 RGB->RGBA: | |
| 165 SDL_SRCALPHA set: | |
| 166 alpha-blend (using the source per-surface alpha value); | |
| 167 set destination alpha to opaque. | |
| 168 SDL_SRCALPHA not set: | |
| 169 copy RGB, set destination alpha to opaque. | |
| 170 both: | |
| 171 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 172 source colour key. | |
| 173 | |
| 174 RGBA->RGBA: | |
| 175 SDL_SRCALPHA set: | |
| 176 alpha-blend (using the source alpha channel) the RGB values; | |
| 177 leave destination alpha untouched. [Note: is this correct?] | |
| 178 SDL_SRCCOLORKEY ignored. | |
| 179 SDL_SRCALPHA not set: | |
| 180 copy all of RGBA to the destination. | |
| 181 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 182 RGB values of the source colour key, ignoring alpha in the | |
| 183 comparison. | |
| 184 | |
| 185 RGB->RGB: | |
| 186 SDL_SRCALPHA set: | |
| 187 alpha-blend (using the source per-surface alpha value). | |
| 188 SDL_SRCALPHA not set: | |
| 189 copy RGB. | |
| 190 both: | |
| 191 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 192 source colour key. | |
| 193 | |
| 194 As a special case, blits from surfaces with per-surface alpha | |
| 195 value of 128 (50% transparency) are optimised and much faster | |
| 196 than other alpha values. This does not apply to surfaces with | |
| 197 alpha channels (per-pixel alpha). | |
| 198 | |
| 199 New functions for manipulating the gamma of the display have | |
| 200 been added: | |
| 201 int SDL_SetGamma(float red, float green, float blue); | |
| 202 int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 203 int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 204 Gamma ramps are tables with 256 entries which map the screen color | |
| 205 components into actually displayed colors. For an example of | |
| 206 implementing gamma correction and gamma fades, see test/testgamma.c | |
| 207 Gamma control is not supported on all hardware. | |
| 208 | |
| 209 1.1.4: | |
| 210 The size of the SDL_CDtrack structure changed from 8 to 12 bytes | |
| 211 as the size of the length member was extended to 32 bits. | |
| 212 | |
| 213 You can now use SDL for 2D blitting with a GL mode by passing the | |
| 214 SDL_OPENGLBLIT flag to SDL_SetVideoMode(). You can specify 16 or | |
| 215 32 bpp, and the data in the framebuffer is put into the GL scene | |
| 216 when you call SDL_UpdateRects(), and the scene will be visible | |
| 217 when you call SDL_GL_SwapBuffers(). | |
| 218 | |
| 219 Run the "testgl" test program with the -logo command line option | |
| 220 to see an example of this blending of 2D and 3D in SDL. | |
| 221 | |
| 222 1.1.3: | |
| 223 Added SDL_FreeRW() to the API, to complement SDL_AllocRW() | |
| 224 | |
| 225 Added resizable window support - just add SDL_RESIZABLE to the | |
| 226 SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events. | |
| 227 See SDL_events.h for details on the new SDL_ResizeEvent structure. | |
| 228 | |
| 229 Added condition variable support, based on mutexes and semaphores. | |
| 230 SDL_CreateCond() | |
| 231 SDL_DestroyCond() | |
| 232 SDL_CondSignal() | |
| 233 SDL_CondBroadcast() | |
| 234 SDL_CondWait() | |
| 235 SDL_CondTimedWait() | |
| 236 The new function prototypes are in SDL_mutex.h | |
| 237 | |
| 238 Added counting semaphore support, based on the mutex primitive. | |
| 239 SDL_CreateSemaphore() | |
| 240 SDL_DestroySemaphore() | |
| 241 SDL_SemWait() | |
| 242 SDL_SemTryWait() | |
| 243 SDL_SemWaitTimeout() | |
| 244 SDL_SemPost() | |
| 245 SDL_SemValue() | |
| 246 The new function prototypes are in SDL_mutex.h | |
| 247 | |
| 248 Added support for asynchronous blitting. To take advantage of this, | |
| 249 you must set the SDL_ASYNCBLIT flag when setting the video mode and | |
| 250 creating surfaces that you want accelerated in this way. You must | |
| 251 lock surfaces that have this flag set, and the lock will block until | |
| 252 any queued blits have completed. | |
| 253 | |
| 254 Added YUV video overlay support. | |
| 255 The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU. | |
| 256 This function creates an overlay surface: | |
| 257 SDL_CreateYUVOverlay() | |
| 258 You must lock and unlock the overlay to get access to the data: | |
| 259 SDL_LockYUVOverlay() SDL_UnlockYUVOverlay() | |
| 260 You can then display the overlay: | |
| 261 SDL_DisplayYUVOverlay() | |
| 262 You must free the overlay when you are done using it: | |
| 263 SDL_FreeYUVOverlay() | |
| 264 See SDL_video.h for the full function prototypes. | |
| 265 | |
| 266 The joystick hat position constants have been changed: | |
| 267 Old constant New constant | |
| 268 ------------ ------------ | |
| 269 0 SDL_HAT_CENTERED | |
| 270 1 SDL_HAT_UP | |
| 271 2 SDL_HAT_RIGHTUP | |
| 272 3 SDL_HAT_RIGHT | |
| 273 4 SDL_HAT_RIGHTDOWN | |
| 274 5 SDL_HAT_DOWN | |
| 275 6 SDL_HAT_LEFTDOWN | |
| 276 7 SDL_HAT_LEFT | |
| 277 8 SDL_HAT_LEFTUP | |
| 278 The new constants are bitmasks, so you can check for the | |
| 279 individual axes like this: | |
| 280 if ( hat_position & SDL_HAT_UP ) { | |
| 281 } | |
| 282 and you'll catch left-up, up, and right-up. | |
| 283 | |
| 284 1.1.2: | |
| 285 Added multiple timer support: | |
| 286 SDL_AddTimer() and SDL_RemoveTimer() | |
| 287 | |
| 288 SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL. | |
| 289 | |
| 290 1.1.0: | |
| 291 Added initial OpenGL support. | |
| 292 First set GL attributes (such as RGB depth, alpha depth, etc.) | |
| 293 SDL_GL_SetAttribute() | |
| 294 Then call SDL_SetVideoMode() with the SDL_OPENGL flag. | |
| 295 Perform all of your normal GL drawing. | |
| 296 Finally swap the buffers with the new SDL function: | |
| 297 SDL_GL_SwapBuffers() | |
| 298 See the new 'testgl' test program for an example of using GL with SDL. | |
| 299 | |
| 300 You can load GL extension functions by using the function: | |
| 301 SDL_GL_LoadProcAddress() | |
| 302 | |
| 303 Added functions to initialize and cleanup specific SDL subsystems: | |
| 304 SDL_InitSubSystem() and SDL_QuitSubSystem() | |
| 305 | |
| 306 Added user-defined event type: | |
| 307 typedef struct { | |
| 308 Uint8 type; | |
| 309 int code; | |
| 310 void *data1; | |
| 311 void *data2; | |
| 312 } SDL_UserEvent; | |
| 313 This structure is in the "user" member of an SDL_Event. | |
| 314 | |
| 315 Added a function to push events into the event queue: | |
| 316 SDL_PushEvent() | |
| 317 | |
| 318 Example of using the new SDL user-defined events: | |
| 319 { | |
| 320 SDL_Event event; | |
| 321 | |
| 322 event.type = SDL_USEREVENT; | |
| 323 event.user.code = my_event_code; | |
| 324 event.user.data1 = significant_data; | |
| 325 event.user.data2 = 0; | |
| 326 SDL_PushEvent(&event); | |
| 327 } | |
| 328 | |
| 329 Added a function to get mouse deltas since last query: | |
| 330 SDL_GetRelativeMouseState() | |
| 331 | |
| 332 Added a boolean datatype to SDL_types.h: | |
| 333 SDL_bool = { SDL_TRUE, SDL_FALSE } | |
| 334 | |
| 335 Added a function to get the current audio status: | |
| 336 SDL_GetAudioState(); | |
| 337 It returns one of: | |
| 338 SDL_AUDIO_STOPPED, | |
| 339 SDL_AUDIO_PLAYING, | |
| 340 SDL_AUDIO_PAUSED | |
| 341 | |
| 342 Added an AAlib driver (ASCII Art) - by Stephane Peter. | |
| 343 | |
| 344 1.0.6: | |
| 345 The input grab state is reset after each call to SDL_SetVideoMode(). | |
| 346 The input is grabbed by default in fullscreen mode, and ungrabbed in | |
| 347 windowed mode. If you want to set input grab to a particular value, | |
| 348 you should set it after each call to SDL_SetVideoMode(). | |
| 349 | |
| 350 1.0.5: | |
| 351 Exposed SDL_AudioInit(), SDL_VideoInit() | |
| 352 Added SDL_AudioDriverName() and SDL_VideoDriverName() | |
| 353 | |
| 354 Added new window manager function: | |
| 355 SDL_WM_ToggleFullScreen() | |
| 356 This is currently implemented only on Linux | |
| 357 | |
| 358 The ALT-ENTER code has been removed - it's not appropriate for a | |
| 359 lib to bind keys when they aren't even emergency escape sequences. | |
| 360 | |
| 361 ALT-ENTER functionality can be implemented with the following code: | |
| 362 | |
| 363 int Handle_AltEnter(const SDL_Event *event) | |
| 364 { | |
| 365 if ( event->type == SDL_KEYDOWN ) { | |
| 366 if ( (event->key.keysym.sym == SDLK_RETURN) && | |
| 367 (event->key.keysym.mod & KMOD_ALT) ) { | |
| 368 SDL_WM_ToggleFullScreen(SDL_GetVideoSurface()); | |
| 369 return(0); | |
| 370 } | |
| 371 } | |
| 372 return(1); | |
| 373 } | |
| 374 SDL_SetEventFilter(Handle_AltEnter); | |
| 375 | |
| 376 1.0.3: | |
| 377 Under X11, if you grab the input and hide the mouse cursor, | |
| 378 the mouse will go into a "relative motion" mode where you | |
| 379 will always get relative motion events no matter how far in | |
| 380 each direction you move the mouse - relative motion is not | |
| 381 bounded by the edges of the window (though the absolute values | |
| 382 of the mouse positions are clamped by the size of the window). | |
| 383 The SVGAlib, framebuffer console, and DirectInput drivers all | |
| 384 have this behavior naturally, and the GDI and BWindow drivers | |
| 385 never go into "relative motion" mode. | |
| 386 | |
| 387 1.0.2: | |
| 388 Added a function to enable keyboard repeat: | |
| 389 SDL_EnableKeyRepeat() | |
| 390 | |
| 391 Added a function to grab the mouse and keyboard input | |
| 392 SDL_WM_GrabInput() | |
| 393 | |
| 394 Added a function to iconify the window. | |
| 395 SDL_WM_IconifyWindow() | |
| 396 If this function succeeds, the application will receive an event | |
| 397 signaling SDL_APPACTIVE event | |
| 398 | |
| 399 1.0.1: | |
| 400 Added constants to SDL_audio.h for 16-bit native byte ordering: | |
| 401 AUDIO_U16SYS, AUDIO_S16SYS | |
| 402 | |
| 403 1.0.0: | |
| 404 New public release | |
| 405 | |
| 406 Version 0.11: | |
| 407 | |
| 408 0.11.5: | |
| 409 A new function SDL_GetVideoSurface() has been added, and returns | |
| 410 a pointer to the current display surface. | |
| 411 | |
| 412 SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and | |
| 413 a new function SDL_CreateRGBSurfaceFrom() has been added to allow | |
| 414 creating an SDL surface from an existing pixel data buffer. | |
| 415 | |
| 416 Added SDL_GetRGB() to the headers and documentation. | |
| 417 | |
| 418 0.11.4: | |
| 419 SDL_SetLibraryPath() is no longer meaningful, and has been removed. | |
| 420 | |
| 421 0.11.3: | |
| 422 A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from | |
| 423 installing fatal signal handlers on operating systems that support | |
| 424 them. | |
| 425 | |
| 426 Version 0.9: | |
| 427 | |
| 428 0.9.15: | |
| 429 SDL_CreateColorCursor() has been removed. Color cursors should | |
| 430 be implemented as sprites, blitted by the application when the | |
| 431 cursor moves. To get smooth color cursor updates when the app | |
| 432 is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init(). This | |
| 433 allows you to handle the mouse motion in another thread from an | |
| 434 event filter function, but is currently only supported by Linux | |
| 435 and BeOS. Note that you'll have to protect the display surface | |
| 436 from multi-threaded access by using mutexes if you do this. | |
| 437 | |
| 438 Thread-safe surface support has been removed from SDL. | |
| 439 This makes blitting somewhat faster, by removing SDL_MiddleBlit(). | |
| 440 Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead. | |
| 441 You can make your surfaces thread-safe by allocating your own | |
| 442 mutex and making lock/unlock calls around accesses to your surface. | |
| 443 | |
| 444 0.9.14: | |
| 445 SDL_GetMouseState() now takes pointers to int rather than Uint16. | |
| 446 | |
| 447 If you set the SDL_WINDOWID environment variable under UNIX X11, | |
| 448 SDL will use that as the main window instead of creating it's own. | |
| 449 This is an unsupported extension to SDL, and not portable at all. | |
| 450 | |
| 451 0.9.13: | |
| 452 Added a function SDL_SetLibraryPath() which can be used to specify | |
| 453 the directory containing the SDL dynamic libraries. This is useful | |
| 454 for commercial applications which ship with particular versions | |
| 455 of the libraries, and for security on multi-user systems. | |
| 456 If this function is not used, the default system directories are | |
| 457 searched using the native dynamic object loading mechanism. | |
| 458 | |
| 459 In order to support C linkage under Visual C++, you must declare | |
| 460 main() without any return type: | |
| 461 main(int argc, char *argv[]) { | |
| 462 /* Do the program... */ | |
| 463 return(0); | |
| 464 } | |
| 465 C++ programs should also return a value if compiled under VC++. | |
| 466 | |
| 467 The blit_endian member of the SDL_VideoInfo struct has been removed. | |
| 468 | |
| 469 SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there | |
| 470 is now no longer any function to translate a keysym to a character. | |
| 471 | |
| 472 The SDL_keysym structure has been extended with a 'scancode' and | |
| 473 'unicode' member. The 'scancode' is a hardware specific scancode | |
| 474 for the key that was pressed, and may be 0. The 'unicode' member | |
| 475 is a 16-bit UNICODE translation of the key that was pressed along | |
| 476 with any modifiers or compose keys that have been pressed. | |
| 477 If no UNICODE translation exists for the key, 'unicode' will be 0. | |
| 478 | |
| 479 Added a function SDL_EnableUNICODE() to enable/disable UNICODE | |
| 480 translation of character keypresses. Translation defaults off. | |
| 481 | |
| 482 To convert existing code to use the new API, change code which | |
| 483 uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(), | |
| 484 and change code which uses it to get the ASCII value of a sym to | |
| 485 use the 'unicode' member of the event keysym. | |
| 486 | |
| 487 0.9.12: | |
| 488 There is partial support for 64-bit datatypes. I don't recommend | |
| 489 you use this if you have a choice, because 64-bit datatypes are not | |
| 490 supported on many platforms. On platforms for which it is supported, | |
| 491 the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and | |
| 492 you can use the Uint64 and Sint64 datatypes. | |
| 493 | |
| 494 Added functions to SDL_endian.h to support 64-bit datatypes: | |
| 495 SDL_SwapLE64(), SDL_SwapBE64(), | |
| 496 SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64() | |
| 497 | |
| 498 A new member "len_ratio" has been added to the SDL_AudioCVT structure, | |
| 499 and allows you to determine either the original buffer length or the | |
| 500 converted buffer length, given the other. | |
| 501 | |
| 502 A new function SDL_FreeWAV() has been added to the API to free data | |
| 503 allocated by SDL_LoadWAV_RW(). This is necessary under Win32 since | |
| 504 the gcc compiled DLL uses a different heap than VC++ compiled apps. | |
| 505 | |
| 506 SDL now has initial support for international keyboards using the | |
| 507 Latin character set. | |
| 508 If a particular mapping is desired, you can set the DEFAULT_KEYBOARD | |
| 509 compile-time variable, or you can set the environment variable | |
| 510 "SDL_KEYBOARD" to a string identifying the keyboard mapping you desire. | |
| 511 The valid values for these variables can be found in SDL_keyboard.c | |
| 512 | |
| 513 Full support for German and French keyboards under X11 is implemented. | |
| 514 | |
| 515 0.9.11: | |
| 516 The THREADED_EVENTS compile-time define has been replaced with the | |
| 517 SDL_INIT_EVENTTHREAD flag. If this flag is passed to SDL_Init(), | |
| 518 SDL will create a separate thread to perform input event handling. | |
| 519 If this flag is passed to SDL_Init(), and the OS doesn't support | |
| 520 event handling in a separate thread, SDL_Init() will fail. | |
| 521 Be sure to add calls to SDL_Delay() in your main thread to allow | |
| 522 the OS to schedule your event thread, or it may starve, leading | |
| 523 to slow event delivery and/or dropped events. | |
| 524 Currently MacOS and Win32 do not support this flag, while BeOS | |
| 525 and Linux do support it. I recommend that your application only | |
| 526 use this flag if absolutely necessary. | |
| 527 | |
| 528 The SDL thread function passed to SDL_CreateThread() now returns a | |
| 529 status. This status can be retrieved by passing a non-NULL pointer | |
| 530 as the 'status' argument to SDL_WaitThread(). | |
| 531 | |
| 532 The volume parameter to SDL_MixAudio() has been increased in range | |
| 533 from (0-8) to (0-128) | |
| 534 | |
| 535 SDL now has a data source abstraction which can encompass a file, | |
| 536 an area of memory, or any custom object you can envision. It uses | |
| 537 these abstractions, SDL_RWops, in the endian read/write functions, | |
| 538 and the built-in WAV and BMP file loaders. This means you can load | |
| 539 WAV chunks from memory mapped files, compressed archives, network | |
| 540 pipes, or anything else that has a data read abstraction. | |
| 541 | |
| 542 There are three built-in data source abstractions: | |
| 543 SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem() | |
| 544 along with a generic data source allocation function: | |
| 545 SDL_AllocRW() | |
| 546 These data sources can be used like stdio file pointers with the | |
| 547 following convenience functions: | |
| 548 SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose() | |
| 549 These functions are defined in the new header file "SDL_rwops.h" | |
| 550 | |
| 551 The endian swapping functions have been turned into macros for speed | |
| 552 and SDL_CalculateEndian() has been removed. SDL_endian.h now defines | |
| 553 SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on | |
| 554 the endianness of the host system. | |
| 555 | |
| 556 The endian read/write functions now take an SDL_RWops pointer | |
| 557 instead of a stdio FILE pointer, to support the new data source | |
| 558 abstraction. | |
| 559 | |
| 560 The SDL_*LoadWAV() functions have been replaced with a single | |
| 561 SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's | |
| 562 first parameter, and a flag whether or not to automatically | |
| 563 free it as the second parameter. SDL_LoadWAV() is a macro for | |
| 564 backward compatibility and convenience: | |
| 565 SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...); | |
| 566 | |
| 567 The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced | |
| 568 with a single function that takes a SDL_RWops pointer as it's | |
| 569 first parameter, and a flag whether or not to automatically | |
| 570 free it as the second parameter. SDL_LoadBMP() and SDL_SaveBMP() | |
| 571 are macros for backward compatibility and convenience: | |
| 572 SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...); | |
| 573 SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...); | |
| 574 Note that these functions use SDL_RWseek() extensively, and should | |
| 575 not be used on pipes or other non-seekable data sources. | |
| 576 | |
| 577 0.9.10: | |
| 578 The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been | |
| 579 extended to support multiple types of display drivers, as well as | |
| 580 safe access to the X11 display when THREADED_EVENTS is enabled. | |
| 581 The new structures are documented in the SDL_syswm.h header file. | |
| 582 | |
| 583 Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard | |
| 584 should now work properly, as well as the "Windows" keys on US | |
| 585 keyboards. | |
| 586 | |
| 587 The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab | |
| 588 instead of trying to open each block device on the system. | |
| 589 The CD must be listed in /etc/fstab as using the iso9660 filesystem. | |
| 590 | |
| 591 On Linux, if you define THREADED_EVENTS at compile time, a separate | |
| 592 thread will be spawned to gather X events asynchronously from the | |
| 593 graphics updates. This hasn't been extensively tested, but it does | |
| 594 provide a means of handling keyboard and mouse input in a separate | |
| 595 thread from the graphics thread. (This is now enabled by default.) | |
| 596 | |
| 597 A special access function SDL_PeepEvents() allows you to manipulate | |
| 598 the event queue in a thread-safe manner, including peeking at events, | |
| 599 removing events of a specified type, and adding new events of arbitrary | |
| 600 type to the queue (use the new 'user' member of the SDL_Event type). | |
| 601 | |
| 602 If you use SDL_PeepEvents() to gather events, then the main graphics | |
| 603 thread needs to call SDL_PumpEvents() periodically to drive the event | |
| 604 loop and generate input events. This is not necessary if SDL has been | |
| 605 compiled with THREADED_EVENTS defined, but doesn't hurt. | |
| 606 | |
| 607 A new function SDL_ThreadID() returns the identifier associated with | |
| 608 the current thread. | |
| 609 | |
| 610 0.9.9: | |
| 611 The AUDIO_STEREO format flag has been replaced with a new 'channels' | |
| 612 member of the SDL_AudioSpec structure. The channels are 1 for mono | |
| 613 audio, and 2 for stereo audio. In the future more channels may be | |
| 614 supported for 3D surround sound. | |
| 615 | |
| 616 The SDL_MixAudio() function now takes an additional volume parameter, | |
| 617 which should be set to SDL_MIX_MAXVOLUME for compatibility with the | |
| 618 original function. | |
| 619 | |
| 620 The CD-ROM functions which take a 'cdrom' parameter can now be | |
| 621 passed NULL, and will act on the last successfully opened CD-ROM. | |
| 622 | |
| 623 0.9.8: | |
| 624 No changes, bugfixes only. | |
| 625 | |
| 626 0.9.7: | |
| 627 No changes, bugfixes only. | |
| 628 | |
| 629 0.9.6: | |
| 630 Added a fast rectangle fill function: SDL_FillRect() | |
| 631 | |
| 632 Addition of a useful function for getting info on the video hardware: | |
| 633 const SDL_VideoInfo *SDL_GetVideoInfo(void) | |
| 634 This function replaces SDL_GetDisplayFormat(). | |
| 635 | |
| 636 Initial support for double-buffering: | |
| 637 Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode() | |
| 638 Update the screen with a new function: SDL_Flip() | |
| 639 | |
| 640 SDL_AllocSurface() takes two new flags: | |
| 641 SDL_SRCCOLORKEY means that the surface will be used for colorkey blits | |
| 642 and if the hardware supports hardware acceleration of colorkey blits | |
| 643 between two surfaces in video memory, to place the surface in video | |
| 644 memory if possible, otherwise it will be placed in system memory. | |
| 645 SDL_SRCALPHA means that the surface will be used for alpha blits and | |
| 646 if the hardware supports hardware acceleration of alpha blits between | |
| 647 two surfaces in video memory, to place the surface in video memory | |
| 648 if possible, otherwise it will be placed in system memory. | |
| 649 SDL_HWSURFACE now means that the surface will be created with the | |
| 650 same format as the display surface, since having surfaces in video | |
| 651 memory is only useful for fast blitting to the screen, and you can't | |
| 652 blit surfaces with different surface formats in video memory. | |
| 653 | |
| 654 0.9.5: | |
| 655 You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume | |
| 656 that the icon consists of the entire image. | |
| 657 | |
| 658 SDL_LowerBlit() is back -- but don't use it on the display surface. | |
| 659 It is exactly the same as SDL_MiddleBlit(), but doesn't check for | |
| 660 thread safety. | |
| 661 | |
| 662 Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take | |
| 663 a FILE pointer instead of a file name. | |
| 664 | |
| 665 Added CD-ROM audio control API: | |
| 666 SDL_CDNumDrives() | |
| 667 SDL_CDName() | |
| 668 SDL_CDOpen() | |
| 669 SDL_CDStatus() | |
| 670 SDL_CDPlayTracks() | |
| 671 SDL_CDPlay() | |
| 672 SDL_CDPause() | |
| 673 SDL_CDResume() | |
| 674 SDL_CDStop() | |
| 675 SDL_CDEject() | |
| 676 SDL_CDClose() | |
| 677 | |
| 678 0.9.4: | |
| 679 No changes, bugfixes only. | |
| 680 | |
| 681 0.9.3: | |
| 682 Mouse motion event now includes relative motion information: | |
| 683 Sint16 event->motion.xrel, Sint16 event->motion.yrel | |
| 684 | |
| 685 X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT | |
| 686 (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile) | |
| 687 | |
| 688 0.9.2: | |
| 689 No changes, bugfixes only. | |
| 690 | |
| 691 0.9.1: | |
| 692 Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now | |
| 693 automatically mapped on blit. | |
| 694 | |
| 695 0.8.0: | |
| 696 SDL stable release |
