From: Max Horn
Subject: Auto hide mouse & other changes
the attached bug adds the auto-hide-mouse feature I talked about
earlier. Turned out it was a lot simpler than I thought, simply by
using our existing code :-). I actually spent much more time on fixing
various bugs in the code and correcting (IMO) some behavior (although,
due to the lack of real specs for SDL, it's probably arguable what
'correct' means...).
* adds auto (un)hiding of mouse depending on whether it is in- or
outside the game window
* computation of course coordinates is correct now (it often and
reproducible got out of sync with the old code, since the NSEvent
window was in some cases *not* our window anymore, so locationInWindow
returned wrong results)
* added a method which at any time returns the mouse coords, relative
to our window
* fixed handling of lost/gain input/mouse/app focus "events"

| 0 | 21 1.2.0: |
| 22 Added SDL_VIDEOEXPOSE event to signal that the screen needs to | |
| 23 be redrawn. This is currently only delivered to OpenGL windows | |
| 24 on X11, though it may be delivered in the future when the video | |
| 25 memory is lost under DirectX. | |
| 26 | |
| 27 1.1.8: | |
| 28 You can pass SDL_NOFRAME to SDL_VideoMode() to create a window | |
| 29 that has no title bar or frame decoration. Fullscreen video | |
| 30 modes automatically have this flag set. | |
| 31 | |
| 32 Added a function to query the clipping rectangle for a surface: | |
| 33 void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 34 | |
| 35 Added a function to query the current event filter: | |
| 36 SDL_EventFilter SDL_GetEventFilter(void) | |
| 37 | |
| 38 If you pass -1 to SDL_ShowCursor(), it won't change the current | |
| 39 cursor visibility state, but will still return it. | |
| 40 | |
| 41 SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning | |
| 42 you can nest them as deep as you want, as long as each lock call | |
| 43 has a matching unlock call. The surface remains locked until the | |
| 44 last matching unlock call. | |
| 45 | |
| 46 Note that you may not blit to or from a locked surface. | |
| 47 | |
| 48 1.1.7: | |
| 49 The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take | |
| 50 arrays of Uint16 values instead of Uint8 values. For the most part, | |
| 51 you can just take your old values and shift them up 8 bits to get | |
| 52 new correct values for your gamma ramps. | |
| 53 | |
| 54 You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface() | |
| 55 and SDL will try to RLE accelerate colorkey and alpha blits in the | |
| 56 resulting surface. | |
| 57 | |
| 58 1.1.6: | |
| 59 Added a function to return the thread ID of a specific thread: | |
| 60 Uint32 SDL_GetThreadID(SDL_Thread *thread) | |
| 61 If 'thread' is NULL, this function returns the id for this thread. | |
| 62 | |
| 63 1.1.5: | |
| 64 The YUV overlay structure has been changed to use an array of | |
| 65 pitches and pixels representing the planes of a YUV image, to | |
| 66 better enable hardware acceleration. The YV12 and IYUV formats | |
| 67 each have three planes, corresponding to the Y, U, and V portions | |
| 68 of the image, while packed pixel YUV formats just have one plane. | |
| 69 | |
| 70 For palettized mode (8bpp), the screen colormap is now split in | |
| 71 a physical and a logical palette. The physical palette determines | |
| 72 what colours the screen pixels will get when displayed, and the | |
| 73 logical palette controls the mapping from blits to/from the screen. | |
| 74 A new function, SDL_SetPalette() has been added to change | |
| 75 logical and physical palettes separately. SDL_SetColors() works | |
| 76 just as before, and is equivalent to calling SDL_SetPalette() with | |
| 77 a flag argument of (SDL_LOGPAL|SDL_PHYSPAL). | |
| 78 | |
| 79 SDL_BlitSurface() no longer modifies the source rectangle, only the | |
| 80 destination rectangle. The width/height members of the destination | |
| 81 rectangle are ignored, only the position is used. | |
| 82 | |
| 83 The old source clipping function SDL_SetClipping() has been replaced | |
| 84 with a more useful function to set the destination clipping rectangle: | |
| 85 SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 86 | |
| 87 Added a function to see what subsystems have been initialized: | |
| 88 Uint32 SDL_WasInit(Uint32 flags) | |
| 89 | |
| 90 The Big Alpha Flip: SDL now treats alpha as opacity like everybody | |
| 91 else, and not as transparency: | |
| 92 | |
| 93 A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255 | |
| 94 A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0 | |
| 95 Values between 0 and 255 vary from fully transparent to fully opaque. | |
| 96 | |
| 97 New functions: | |
| 98 SDL_DisplayFormatAlpha() | |
| 99 Returns a surface converted to a format with alpha-channel | |
| 100 that can be blit efficiently to the screen. (In other words, | |
| 101 like SDL_DisplayFormat() but the resulting surface has | |
| 102 an alpha channel.) This is useful for surfaces with alpha. | |
| 103 SDL_MapRGBA() | |
| 104 Works as SDL_MapRGB() but takes an additional alpha parameter. | |
| 105 SDL_GetRGBA() | |
| 106 Works as SDL_GetRGB() but also returns the alpha value | |
| 107 (SDL_ALPHA_OPAQUE for formats without an alpha channel) | |
| 108 | |
| 109 Both SDL_GetRGB() and SDL_GetRGBA() now always return values in | |
| 110 the [0..255] interval. Previously, SDL_GetRGB() would return | |
| 111 (0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format. | |
| 112 (N.B.: This is broken for bit fields < 3 bits.) | |
| 113 | |
| 114 SDL_MapRGB() returns pixels in which the alpha channel is set opaque. | |
| 115 | |
| 116 SDL_SetAlpha() can now be used for both setting the per-surface | |
| 117 alpha, using the new way of thinking of alpha, and also to enable | |
| 118 and disable per-pixel alpha blending for surfaces with an alpha | |
| 119 channel: | |
| 120 To disable alpha blending: | |
| 121 SDL_SetAlpha(surface, 0, 0); | |
| 122 To re-enable alpha blending: | |
| 123 SDL_SetAlpha(surface, SDL_SRCALPHA, 0); | |
| 124 Surfaces with an alpha channel have blending enabled by default. | |
| 125 | |
| 126 SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests | |
| 127 RLE acceleration of blits, just as like with SDL_SetColorKey(). | |
| 128 This flag can be set for both surfaces with an alpha channel | |
| 129 and surfaces with an alpha value set by SDL_SetAlpha(). | |
| 130 As always, RLE surfaces must be locked before pixel access is | |
| 131 allowed, and unlocked before any other SDL operations are done | |
| 132 on it. | |
| 133 | |
| 134 The blit semantics for surfaces with and without alpha and colorkey | |
| 135 have now been defined: | |
| 136 | |
| 137 RGBA->RGB: | |
| 138 SDL_SRCALPHA set: | |
| 139 alpha-blend (using alpha-channel). | |
| 140 SDL_SRCCOLORKEY ignored. | |
| 141 SDL_SRCALPHA not set: | |
| 142 copy RGB. | |
| 143 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 144 RGB values of the source colour key, ignoring alpha in the | |
| 145 comparison. | |
| 146 | |
| 147 RGB->RGBA: | |
| 148 SDL_SRCALPHA set: | |
| 149 alpha-blend (using the source per-surface alpha value); | |
| 150 set destination alpha to opaque. | |
| 151 SDL_SRCALPHA not set: | |
| 152 copy RGB, set destination alpha to opaque. | |
| 153 both: | |
| 154 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 155 source colour key. | |
| 156 | |
| 157 RGBA->RGBA: | |
| 158 SDL_SRCALPHA set: | |
| 159 alpha-blend (using the source alpha channel) the RGB values; | |
| 160 leave destination alpha untouched. [Note: is this correct?] | |
| 161 SDL_SRCCOLORKEY ignored. | |
| 162 SDL_SRCALPHA not set: | |
| 163 copy all of RGBA to the destination. | |
| 164 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 165 RGB values of the source colour key, ignoring alpha in the | |
| 166 comparison. | |
| 167 | |
| 168 RGB->RGB: | |
| 169 SDL_SRCALPHA set: | |
| 170 alpha-blend (using the source per-surface alpha value). | |
| 171 SDL_SRCALPHA not set: | |
| 172 copy RGB. | |
| 173 both: | |
| 174 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 175 source colour key. | |
| 176 | |
| 177 As a special case, blits from surfaces with per-surface alpha | |
| 178 value of 128 (50% transparency) are optimised and much faster | |
| 179 than other alpha values. This does not apply to surfaces with | |
| 180 alpha channels (per-pixel alpha). | |
| 181 | |
| 182 New functions for manipulating the gamma of the display have | |
| 183 been added: | |
| 184 int SDL_SetGamma(float red, float green, float blue); | |
| 185 int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 186 int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 187 Gamma ramps are tables with 256 entries which map the screen color | |
| 188 components into actually displayed colors. For an example of | |
| 189 implementing gamma correction and gamma fades, see test/testgamma.c | |
| 190 Gamma control is not supported on all hardware. | |
| 191 | |
| 192 1.1.4: | |
| 193 The size of the SDL_CDtrack structure changed from 8 to 12 bytes | |
| 194 as the size of the length member was extended to 32 bits. | |
| 195 | |
| 196 You can now use SDL for 2D blitting with a GL mode by passing the | |
| 197 SDL_OPENGLBLIT flag to SDL_SetVideoMode(). You can specify 16 or | |
| 198 32 bpp, and the data in the framebuffer is put into the GL scene | |
| 199 when you call SDL_UpdateRects(), and the scene will be visible | |
| 200 when you call SDL_GL_SwapBuffers(). | |
| 201 | |
| 202 Run the "testgl" test program with the -logo command line option | |
| 203 to see an example of this blending of 2D and 3D in SDL. | |
| 204 | |
| 205 1.1.3: | |
| 206 Added SDL_FreeRW() to the API, to complement SDL_AllocRW() | |
| 207 | |
| 208 Added resizable window support - just add SDL_RESIZABLE to the | |
| 209 SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events. | |
| 210 See SDL_events.h for details on the new SDL_ResizeEvent structure. | |
| 211 | |
| 212 Added condition variable support, based on mutexes and semaphores. | |
| 213 SDL_CreateCond() | |
| 214 SDL_DestroyCond() | |
| 215 SDL_CondSignal() | |
| 216 SDL_CondBroadcast() | |
| 217 SDL_CondWait() | |
| 218 SDL_CondTimedWait() | |
| 219 The new function prototypes are in SDL_mutex.h | |
| 220 | |
| 221 Added counting semaphore support, based on the mutex primitive. | |
| 222 SDL_CreateSemaphore() | |
| 223 SDL_DestroySemaphore() | |
| 224 SDL_SemWait() | |
| 225 SDL_SemTryWait() | |
| 226 SDL_SemWaitTimeout() | |
| 227 SDL_SemPost() | |
| 228 SDL_SemValue() | |
| 229 The new function prototypes are in SDL_mutex.h | |
| 230 | |
| 231 Added support for asynchronous blitting. To take advantage of this, | |
| 232 you must set the SDL_ASYNCBLIT flag when setting the video mode and | |
| 233 creating surfaces that you want accelerated in this way. You must | |
| 234 lock surfaces that have this flag set, and the lock will block until | |
| 235 any queued blits have completed. | |
| 236 | |
| 237 Added YUV video overlay support. | |
| 238 The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU. | |
| 239 This function creates an overlay surface: | |
| 240 SDL_CreateYUVOverlay() | |
| 241 You must lock and unlock the overlay to get access to the data: | |
| 242 SDL_LockYUVOverlay() SDL_UnlockYUVOverlay() | |
| 243 You can then display the overlay: | |
| 244 SDL_DisplayYUVOverlay() | |
| 245 You must free the overlay when you are done using it: | |
| 246 SDL_FreeYUVOverlay() | |
| 247 See SDL_video.h for the full function prototypes. | |
| 248 | |
| 249 The joystick hat position constants have been changed: | |
| 250 Old constant New constant | |
| 251 ------------ ------------ | |
| 252 0 SDL_HAT_CENTERED | |
| 253 1 SDL_HAT_UP | |
| 254 2 SDL_HAT_RIGHTUP | |
| 255 3 SDL_HAT_RIGHT | |
| 256 4 SDL_HAT_RIGHTDOWN | |
| 257 5 SDL_HAT_DOWN | |
| 258 6 SDL_HAT_LEFTDOWN | |
| 259 7 SDL_HAT_LEFT | |
| 260 8 SDL_HAT_LEFTUP | |
| 261 The new constants are bitmasks, so you can check for the | |
| 262 individual axes like this: | |
| 263 if ( hat_position & SDL_HAT_UP ) { | |
| 264 } | |
| 265 and you'll catch left-up, up, and right-up. | |
| 266 | |
| 267 1.1.2: | |
| 268 Added multiple timer support: | |
| 269 SDL_AddTimer() and SDL_RemoveTimer() | |
| 270 | |
| 271 SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL. | |
| 272 | |
| 273 1.1.0: | |
| 274 Added initial OpenGL support. | |
| 275 First set GL attributes (such as RGB depth, alpha depth, etc.) | |
| 276 SDL_GL_SetAttribute() | |
| 277 Then call SDL_SetVideoMode() with the SDL_OPENGL flag. | |
| 278 Perform all of your normal GL drawing. | |
| 279 Finally swap the buffers with the new SDL function: | |
| 280 SDL_GL_SwapBuffers() | |
| 281 See the new 'testgl' test program for an example of using GL with SDL. | |
| 282 | |
| 283 You can load GL extension functions by using the function: | |
| 284 SDL_GL_LoadProcAddress() | |
| 285 | |
| 286 Added functions to initialize and cleanup specific SDL subsystems: | |
| 287 SDL_InitSubSystem() and SDL_QuitSubSystem() | |
| 288 | |
| 289 Added user-defined event type: | |
| 290 typedef struct { | |
| 291 Uint8 type; | |
| 292 int code; | |
| 293 void *data1; | |
| 294 void *data2; | |
| 295 } SDL_UserEvent; | |
| 296 This structure is in the "user" member of an SDL_Event. | |
| 297 | |
| 298 Added a function to push events into the event queue: | |
| 299 SDL_PushEvent() | |
| 300 | |
| 301 Example of using the new SDL user-defined events: | |
| 302 { | |
| 303 SDL_Event event; | |
| 304 | |
| 305 event.type = SDL_USEREVENT; | |
| 306 event.user.code = my_event_code; | |
| 307 event.user.data1 = significant_data; | |
| 308 event.user.data2 = 0; | |
| 309 SDL_PushEvent(&event); | |
| 310 } | |
| 311 | |
| 312 Added a function to get mouse deltas since last query: | |
| 313 SDL_GetRelativeMouseState() | |
| 314 | |
| 315 Added a boolean datatype to SDL_types.h: | |
| 316 SDL_bool = { SDL_TRUE, SDL_FALSE } | |
| 317 | |
| 318 Added a function to get the current audio status: | |
| 319 SDL_GetAudioState(); | |
| 320 It returns one of: | |
| 321 SDL_AUDIO_STOPPED, | |
| 322 SDL_AUDIO_PLAYING, | |
| 323 SDL_AUDIO_PAUSED | |
| 324 | |
| 325 Added an AAlib driver (ASCII Art) - by Stephane Peter. | |
| 326 | |
| 327 1.0.6: | |
| 328 The input grab state is reset after each call to SDL_SetVideoMode(). | |
| 329 The input is grabbed by default in fullscreen mode, and ungrabbed in | |
| 330 windowed mode. If you want to set input grab to a particular value, | |
| 331 you should set it after each call to SDL_SetVideoMode(). | |
| 332 | |
| 333 1.0.5: | |
| 334 Exposed SDL_AudioInit(), SDL_VideoInit() | |
| 335 Added SDL_AudioDriverName() and SDL_VideoDriverName() | |
| 336 | |
| 337 Added new window manager function: | |
| 338 SDL_WM_ToggleFullScreen() | |
| 339 This is currently implemented only on Linux | |
| 340 | |
| 341 The ALT-ENTER code has been removed - it's not appropriate for a | |
| 342 lib to bind keys when they aren't even emergency escape sequences. | |
| 343 | |
| 344 ALT-ENTER functionality can be implemented with the following code: | |
| 345 | |
| 346 int Handle_AltEnter(const SDL_Event *event) | |
| 347 { | |
| 348 if ( event->type == SDL_KEYDOWN ) { | |
| 349 if ( (event->key.keysym.sym == SDLK_RETURN) && | |
| 350 (event->key.keysym.mod & KMOD_ALT) ) { | |
| 351 SDL_WM_ToggleFullScreen(SDL_GetVideoSurface()); | |
| 352 return(0); | |
| 353 } | |
| 354 } | |
| 355 return(1); | |
| 356 } | |
| 357 SDL_SetEventFilter(Handle_AltEnter); | |
| 358 | |
| 359 1.0.3: | |
| 360 Under X11, if you grab the input and hide the mouse cursor, | |
| 361 the mouse will go into a "relative motion" mode where you | |
| 362 will always get relative motion events no matter how far in | |
| 363 each direction you move the mouse - relative motion is not | |
| 364 bounded by the edges of the window (though the absolute values | |
| 365 of the mouse positions are clamped by the size of the window). | |
| 366 The SVGAlib, framebuffer console, and DirectInput drivers all | |
| 367 have this behavior naturally, and the GDI and BWindow drivers | |
| 368 never go into "relative motion" mode. | |
| 369 | |
| 370 1.0.2: | |
| 371 Added a function to enable keyboard repeat: | |
| 372 SDL_EnableKeyRepeat() | |
| 373 | |
| 374 Added a function to grab the mouse and keyboard input | |
| 375 SDL_WM_GrabInput() | |
| 376 | |
| 377 Added a function to iconify the window. | |
| 378 SDL_WM_IconifyWindow() | |
| 379 If this function succeeds, the application will receive an event | |
| 380 signaling SDL_APPACTIVE event | |
| 381 | |
| 382 1.0.1: | |
| 383 Added constants to SDL_audio.h for 16-bit native byte ordering: | |
| 384 AUDIO_U16SYS, AUDIO_S16SYS | |
| 385 | |
| 386 1.0.0: | |
| 387 New public release | |
| 388 | |
| 389 Version 0.11: | |
| 390 | |
| 391 0.11.5: | |
| 392 A new function SDL_GetVideoSurface() has been added, and returns | |
| 393 a pointer to the current display surface. | |
| 394 | |
| 395 SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and | |
| 396 a new function SDL_CreateRGBSurfaceFrom() has been added to allow | |
| 397 creating an SDL surface from an existing pixel data buffer. | |
| 398 | |
| 399 Added SDL_GetRGB() to the headers and documentation. | |
| 400 | |
| 401 0.11.4: | |
| 402 SDL_SetLibraryPath() is no longer meaningful, and has been removed. | |
| 403 | |
| 404 0.11.3: | |
| 405 A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from | |
| 406 installing fatal signal handlers on operating systems that support | |
| 407 them. | |
| 408 | |
| 409 Version 0.9: | |
| 410 | |
| 411 0.9.15: | |
| 412 SDL_CreateColorCursor() has been removed. Color cursors should | |
| 413 be implemented as sprites, blitted by the application when the | |
| 414 cursor moves. To get smooth color cursor updates when the app | |
| 415 is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init(). This | |
| 416 allows you to handle the mouse motion in another thread from an | |
| 417 event filter function, but is currently only supported by Linux | |
| 418 and BeOS. Note that you'll have to protect the display surface | |
| 419 from multi-threaded access by using mutexes if you do this. | |
| 420 | |
| 421 Thread-safe surface support has been removed from SDL. | |
| 422 This makes blitting somewhat faster, by removing SDL_MiddleBlit(). | |
| 423 Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead. | |
| 424 You can make your surfaces thread-safe by allocating your own | |
| 425 mutex and making lock/unlock calls around accesses to your surface. | |
| 426 | |
| 427 0.9.14: | |
| 428 SDL_GetMouseState() now takes pointers to int rather than Uint16. | |
| 429 | |
| 430 If you set the SDL_WINDOWID environment variable under UNIX X11, | |
| 431 SDL will use that as the main window instead of creating it's own. | |
| 432 This is an unsupported extension to SDL, and not portable at all. | |
| 433 | |
| 434 0.9.13: | |
| 435 Added a function SDL_SetLibraryPath() which can be used to specify | |
| 436 the directory containing the SDL dynamic libraries. This is useful | |
| 437 for commercial applications which ship with particular versions | |
| 438 of the libraries, and for security on multi-user systems. | |
| 439 If this function is not used, the default system directories are | |
| 440 searched using the native dynamic object loading mechanism. | |
| 441 | |
| 442 In order to support C linkage under Visual C++, you must declare | |
| 443 main() without any return type: | |
| 444 main(int argc, char *argv[]) { | |
| 445 /* Do the program... */ | |
| 446 return(0); | |
| 447 } | |
| 448 C++ programs should also return a value if compiled under VC++. | |
| 449 | |
| 450 The blit_endian member of the SDL_VideoInfo struct has been removed. | |
| 451 | |
| 452 SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there | |
| 453 is now no longer any function to translate a keysym to a character. | |
| 454 | |
| 455 The SDL_keysym structure has been extended with a 'scancode' and | |
| 456 'unicode' member. The 'scancode' is a hardware specific scancode | |
| 457 for the key that was pressed, and may be 0. The 'unicode' member | |
| 458 is a 16-bit UNICODE translation of the key that was pressed along | |
| 459 with any modifiers or compose keys that have been pressed. | |
| 460 If no UNICODE translation exists for the key, 'unicode' will be 0. | |
| 461 | |
| 462 Added a function SDL_EnableUNICODE() to enable/disable UNICODE | |
| 463 translation of character keypresses. Translation defaults off. | |
| 464 | |
| 465 To convert existing code to use the new API, change code which | |
| 466 uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(), | |
| 467 and change code which uses it to get the ASCII value of a sym to | |
| 468 use the 'unicode' member of the event keysym. | |
| 469 | |
| 470 0.9.12: | |
| 471 There is partial support for 64-bit datatypes. I don't recommend | |
| 472 you use this if you have a choice, because 64-bit datatypes are not | |
| 473 supported on many platforms. On platforms for which it is supported, | |
| 474 the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and | |
| 475 you can use the Uint64 and Sint64 datatypes. | |
| 476 | |
| 477 Added functions to SDL_endian.h to support 64-bit datatypes: | |
| 478 SDL_SwapLE64(), SDL_SwapBE64(), | |
| 479 SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64() | |
| 480 | |
| 481 A new member "len_ratio" has been added to the SDL_AudioCVT structure, | |
| 482 and allows you to determine either the original buffer length or the | |
| 483 converted buffer length, given the other. | |
| 484 | |
| 485 A new function SDL_FreeWAV() has been added to the API to free data | |
| 486 allocated by SDL_LoadWAV_RW(). This is necessary under Win32 since | |
| 487 the gcc compiled DLL uses a different heap than VC++ compiled apps. | |
| 488 | |
| 489 SDL now has initial support for international keyboards using the | |
| 490 Latin character set. | |
| 491 If a particular mapping is desired, you can set the DEFAULT_KEYBOARD | |
| 492 compile-time variable, or you can set the environment variable | |
| 493 "SDL_KEYBOARD" to a string identifying the keyboard mapping you desire. | |
| 494 The valid values for these variables can be found in SDL_keyboard.c | |
| 495 | |
| 496 Full support for German and French keyboards under X11 is implemented. | |
| 497 | |
| 498 0.9.11: | |
| 499 The THREADED_EVENTS compile-time define has been replaced with the | |
| 500 SDL_INIT_EVENTTHREAD flag. If this flag is passed to SDL_Init(), | |
| 501 SDL will create a separate thread to perform input event handling. | |
| 502 If this flag is passed to SDL_Init(), and the OS doesn't support | |
| 503 event handling in a separate thread, SDL_Init() will fail. | |
| 504 Be sure to add calls to SDL_Delay() in your main thread to allow | |
| 505 the OS to schedule your event thread, or it may starve, leading | |
| 506 to slow event delivery and/or dropped events. | |
| 507 Currently MacOS and Win32 do not support this flag, while BeOS | |
| 508 and Linux do support it. I recommend that your application only | |
| 509 use this flag if absolutely necessary. | |
| 510 | |
| 511 The SDL thread function passed to SDL_CreateThread() now returns a | |
| 512 status. This status can be retrieved by passing a non-NULL pointer | |
| 513 as the 'status' argument to SDL_WaitThread(). | |
| 514 | |
| 515 The volume parameter to SDL_MixAudio() has been increased in range | |
| 516 from (0-8) to (0-128) | |
| 517 | |
| 518 SDL now has a data source abstraction which can encompass a file, | |
| 519 an area of memory, or any custom object you can envision. It uses | |
| 520 these abstractions, SDL_RWops, in the endian read/write functions, | |
| 521 and the built-in WAV and BMP file loaders. This means you can load | |
| 522 WAV chunks from memory mapped files, compressed archives, network | |
| 523 pipes, or anything else that has a data read abstraction. | |
| 524 | |
| 525 There are three built-in data source abstractions: | |
| 526 SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem() | |
| 527 along with a generic data source allocation function: | |
| 528 SDL_AllocRW() | |
| 529 These data sources can be used like stdio file pointers with the | |
| 530 following convenience functions: | |
| 531 SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose() | |
| 532 These functions are defined in the new header file "SDL_rwops.h" | |
| 533 | |
| 534 The endian swapping functions have been turned into macros for speed | |
| 535 and SDL_CalculateEndian() has been removed. SDL_endian.h now defines | |
| 536 SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on | |
| 537 the endianness of the host system. | |
| 538 | |
| 539 The endian read/write functions now take an SDL_RWops pointer | |
| 540 instead of a stdio FILE pointer, to support the new data source | |
| 541 abstraction. | |
| 542 | |
| 543 The SDL_*LoadWAV() functions have been replaced with a single | |
| 544 SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's | |
| 545 first parameter, and a flag whether or not to automatically | |
| 546 free it as the second parameter. SDL_LoadWAV() is a macro for | |
| 547 backward compatibility and convenience: | |
| 548 SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...); | |
| 549 | |
| 550 The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced | |
| 551 with a single function that takes a SDL_RWops pointer as it's | |
| 552 first parameter, and a flag whether or not to automatically | |
| 553 free it as the second parameter. SDL_LoadBMP() and SDL_SaveBMP() | |
| 554 are macros for backward compatibility and convenience: | |
| 555 SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...); | |
| 556 SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...); | |
| 557 Note that these functions use SDL_RWseek() extensively, and should | |
| 558 not be used on pipes or other non-seekable data sources. | |
| 559 | |
| 560 0.9.10: | |
| 561 The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been | |
| 562 extended to support multiple types of display drivers, as well as | |
| 563 safe access to the X11 display when THREADED_EVENTS is enabled. | |
| 564 The new structures are documented in the SDL_syswm.h header file. | |
| 565 | |
| 566 Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard | |
| 567 should now work properly, as well as the "Windows" keys on US | |
| 568 keyboards. | |
| 569 | |
| 570 The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab | |
| 571 instead of trying to open each block device on the system. | |
| 572 The CD must be listed in /etc/fstab as using the iso9660 filesystem. | |
| 573 | |
| 574 On Linux, if you define THREADED_EVENTS at compile time, a separate | |
| 575 thread will be spawned to gather X events asynchronously from the | |
| 576 graphics updates. This hasn't been extensively tested, but it does | |
| 577 provide a means of handling keyboard and mouse input in a separate | |
| 578 thread from the graphics thread. (This is now enabled by default.) | |
| 579 | |
| 580 A special access function SDL_PeepEvents() allows you to manipulate | |
| 581 the event queue in a thread-safe manner, including peeking at events, | |
| 582 removing events of a specified type, and adding new events of arbitrary | |
| 583 type to the queue (use the new 'user' member of the SDL_Event type). | |
| 584 | |
| 585 If you use SDL_PeepEvents() to gather events, then the main graphics | |
| 586 thread needs to call SDL_PumpEvents() periodically to drive the event | |
| 587 loop and generate input events. This is not necessary if SDL has been | |
| 588 compiled with THREADED_EVENTS defined, but doesn't hurt. | |
| 589 | |
| 590 A new function SDL_ThreadID() returns the identifier associated with | |
| 591 the current thread. | |
| 592 | |
| 593 0.9.9: | |
| 594 The AUDIO_STEREO format flag has been replaced with a new 'channels' | |
| 595 member of the SDL_AudioSpec structure. The channels are 1 for mono | |
| 596 audio, and 2 for stereo audio. In the future more channels may be | |
| 597 supported for 3D surround sound. | |
| 598 | |
| 599 The SDL_MixAudio() function now takes an additional volume parameter, | |
| 600 which should be set to SDL_MIX_MAXVOLUME for compatibility with the | |
| 601 original function. | |
| 602 | |
| 603 The CD-ROM functions which take a 'cdrom' parameter can now be | |
| 604 passed NULL, and will act on the last successfully opened CD-ROM. | |
| 605 | |
| 606 0.9.8: | |
| 607 No changes, bugfixes only. | |
| 608 | |
| 609 0.9.7: | |
| 610 No changes, bugfixes only. | |
| 611 | |
| 612 0.9.6: | |
| 613 Added a fast rectangle fill function: SDL_FillRect() | |
| 614 | |
| 615 Addition of a useful function for getting info on the video hardware: | |
| 616 const SDL_VideoInfo *SDL_GetVideoInfo(void) | |
| 617 This function replaces SDL_GetDisplayFormat(). | |
| 618 | |
| 619 Initial support for double-buffering: | |
| 620 Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode() | |
| 621 Update the screen with a new function: SDL_Flip() | |
| 622 | |
| 623 SDL_AllocSurface() takes two new flags: | |
| 624 SDL_SRCCOLORKEY means that the surface will be used for colorkey blits | |
| 625 and if the hardware supports hardware acceleration of colorkey blits | |
| 626 between two surfaces in video memory, to place the surface in video | |
| 627 memory if possible, otherwise it will be placed in system memory. | |
| 628 SDL_SRCALPHA means that the surface will be used for alpha blits and | |
| 629 if the hardware supports hardware acceleration of alpha blits between | |
| 630 two surfaces in video memory, to place the surface in video memory | |
| 631 if possible, otherwise it will be placed in system memory. | |
| 632 SDL_HWSURFACE now means that the surface will be created with the | |
| 633 same format as the display surface, since having surfaces in video | |
| 634 memory is only useful for fast blitting to the screen, and you can't | |
| 635 blit surfaces with different surface formats in video memory. | |
| 636 | |
| 637 0.9.5: | |
| 638 You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume | |
| 639 that the icon consists of the entire image. | |
| 640 | |
| 641 SDL_LowerBlit() is back -- but don't use it on the display surface. | |
| 642 It is exactly the same as SDL_MiddleBlit(), but doesn't check for | |
| 643 thread safety. | |
| 644 | |
| 645 Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take | |
| 646 a FILE pointer instead of a file name. | |
| 647 | |
| 648 Added CD-ROM audio control API: | |
| 649 SDL_CDNumDrives() | |
| 650 SDL_CDName() | |
| 651 SDL_CDOpen() | |
| 652 SDL_CDStatus() | |
| 653 SDL_CDPlayTracks() | |
| 654 SDL_CDPlay() | |
| 655 SDL_CDPause() | |
| 656 SDL_CDResume() | |
| 657 SDL_CDStop() | |
| 658 SDL_CDEject() | |
| 659 SDL_CDClose() | |
| 660 | |
| 661 0.9.4: | |
| 662 No changes, bugfixes only. | |
| 663 | |
| 664 0.9.3: | |
| 665 Mouse motion event now includes relative motion information: | |
| 666 Sint16 event->motion.xrel, Sint16 event->motion.yrel | |
| 667 | |
| 668 X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT | |
| 669 (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile) | |
| 670 | |
| 671 0.9.2: | |
| 672 No changes, bugfixes only. | |
| 673 | |
| 674 0.9.1: | |
| 675 Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now | |
| 676 automatically mapped on blit. | |
| 677 | |
| 678 0.8.0: | |
| 679 SDL stable release |
