Fixed bug #38
I'm using SDL 1.2.9 with Visual C++ 7.0 on Windows 2000.
Here's the setup: my game starts in a window, with
SDL_WM_GrabInput(SDL_GRAB_ON) to constrain the cursor to the game window. The
mouse cursor is outside of the window when the game launches, and when the
window appears the cursor is grabbed and placed at the top left corner of the
inside of the game window. At this point, if I click the mouse without moving
it, the SDL_MOUSEBUTTONDOWN event's mouse coordinates are (65535,65535).

| 0 | 26 1.2.0: |
| 27 Added SDL_VIDEOEXPOSE event to signal that the screen needs to | |
| 28 be redrawn. This is currently only delivered to OpenGL windows | |
| 29 on X11, though it may be delivered in the future when the video | |
| 30 memory is lost under DirectX. | |
| 31 | |
| 32 1.1.8: | |
| 33 You can pass SDL_NOFRAME to SDL_VideoMode() to create a window | |
| 34 that has no title bar or frame decoration. Fullscreen video | |
| 35 modes automatically have this flag set. | |
| 36 | |
| 37 Added a function to query the clipping rectangle for a surface: | |
| 38 void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 39 | |
| 40 Added a function to query the current event filter: | |
| 41 SDL_EventFilter SDL_GetEventFilter(void) | |
| 42 | |
| 43 If you pass -1 to SDL_ShowCursor(), it won't change the current | |
| 44 cursor visibility state, but will still return it. | |
| 45 | |
| 46 SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning | |
| 47 you can nest them as deep as you want, as long as each lock call | |
| 48 has a matching unlock call. The surface remains locked until the | |
| 49 last matching unlock call. | |
| 50 | |
| 51 Note that you may not blit to or from a locked surface. | |
| 52 | |
| 53 1.1.7: | |
| 54 The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take | |
| 55 arrays of Uint16 values instead of Uint8 values. For the most part, | |
| 56 you can just take your old values and shift them up 8 bits to get | |
| 57 new correct values for your gamma ramps. | |
| 58 | |
| 59 You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface() | |
| 60 and SDL will try to RLE accelerate colorkey and alpha blits in the | |
| 61 resulting surface. | |
| 62 | |
| 63 1.1.6: | |
| 64 Added a function to return the thread ID of a specific thread: | |
| 65 Uint32 SDL_GetThreadID(SDL_Thread *thread) | |
| 66 If 'thread' is NULL, this function returns the id for this thread. | |
| 67 | |
| 68 1.1.5: | |
| 69 The YUV overlay structure has been changed to use an array of | |
| 70 pitches and pixels representing the planes of a YUV image, to | |
| 71 better enable hardware acceleration. The YV12 and IYUV formats | |
| 72 each have three planes, corresponding to the Y, U, and V portions | |
| 73 of the image, while packed pixel YUV formats just have one plane. | |
| 74 | |
| 75 For palettized mode (8bpp), the screen colormap is now split in | |
| 76 a physical and a logical palette. The physical palette determines | |
| 77 what colours the screen pixels will get when displayed, and the | |
| 78 logical palette controls the mapping from blits to/from the screen. | |
| 79 A new function, SDL_SetPalette() has been added to change | |
| 80 logical and physical palettes separately. SDL_SetColors() works | |
| 81 just as before, and is equivalent to calling SDL_SetPalette() with | |
| 82 a flag argument of (SDL_LOGPAL|SDL_PHYSPAL). | |
| 83 | |
| 84 SDL_BlitSurface() no longer modifies the source rectangle, only the | |
| 85 destination rectangle. The width/height members of the destination | |
| 86 rectangle are ignored, only the position is used. | |
| 87 | |
| 88 The old source clipping function SDL_SetClipping() has been replaced | |
| 89 with a more useful function to set the destination clipping rectangle: | |
| 90 SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 91 | |
| 92 Added a function to see what subsystems have been initialized: | |
| 93 Uint32 SDL_WasInit(Uint32 flags) | |
| 94 | |
| 95 The Big Alpha Flip: SDL now treats alpha as opacity like everybody | |
| 96 else, and not as transparency: | |
| 97 | |
| 98 A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255 | |
| 99 A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0 | |
| 100 Values between 0 and 255 vary from fully transparent to fully opaque. | |
| 101 | |
| 102 New functions: | |
| 103 SDL_DisplayFormatAlpha() | |
| 104 Returns a surface converted to a format with alpha-channel | |
| 105 that can be blit efficiently to the screen. (In other words, | |
| 106 like SDL_DisplayFormat() but the resulting surface has | |
| 107 an alpha channel.) This is useful for surfaces with alpha. | |
| 108 SDL_MapRGBA() | |
| 109 Works as SDL_MapRGB() but takes an additional alpha parameter. | |
| 110 SDL_GetRGBA() | |
| 111 Works as SDL_GetRGB() but also returns the alpha value | |
| 112 (SDL_ALPHA_OPAQUE for formats without an alpha channel) | |
| 113 | |
| 114 Both SDL_GetRGB() and SDL_GetRGBA() now always return values in | |
| 115 the [0..255] interval. Previously, SDL_GetRGB() would return | |
| 116 (0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format. | |
| 117 (N.B.: This is broken for bit fields < 3 bits.) | |
| 118 | |
| 119 SDL_MapRGB() returns pixels in which the alpha channel is set opaque. | |
| 120 | |
| 121 SDL_SetAlpha() can now be used for both setting the per-surface | |
| 122 alpha, using the new way of thinking of alpha, and also to enable | |
| 123 and disable per-pixel alpha blending for surfaces with an alpha | |
| 124 channel: | |
| 125 To disable alpha blending: | |
| 126 SDL_SetAlpha(surface, 0, 0); | |
| 127 To re-enable alpha blending: | |
| 128 SDL_SetAlpha(surface, SDL_SRCALPHA, 0); | |
| 129 Surfaces with an alpha channel have blending enabled by default. | |
| 130 | |
| 131 SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests | |
| 132 RLE acceleration of blits, just as like with SDL_SetColorKey(). | |
| 133 This flag can be set for both surfaces with an alpha channel | |
| 134 and surfaces with an alpha value set by SDL_SetAlpha(). | |
| 135 As always, RLE surfaces must be locked before pixel access is | |
| 136 allowed, and unlocked before any other SDL operations are done | |
| 137 on it. | |
| 138 | |
| 139 The blit semantics for surfaces with and without alpha and colorkey | |
| 140 have now been defined: | |
| 141 | |
| 142 RGBA->RGB: | |
| 143 SDL_SRCALPHA set: | |
| 144 alpha-blend (using alpha-channel). | |
| 145 SDL_SRCCOLORKEY ignored. | |
| 146 SDL_SRCALPHA not set: | |
| 147 copy RGB. | |
| 148 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 149 RGB values of the source colour key, ignoring alpha in the | |
| 150 comparison. | |
| 151 | |
| 152 RGB->RGBA: | |
| 153 SDL_SRCALPHA set: | |
| 154 alpha-blend (using the source per-surface alpha value); | |
| 155 set destination alpha to opaque. | |
| 156 SDL_SRCALPHA not set: | |
| 157 copy RGB, set destination alpha to opaque. | |
| 158 both: | |
| 159 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 160 source colour key. | |
| 161 | |
| 162 RGBA->RGBA: | |
| 163 SDL_SRCALPHA set: | |
| 164 alpha-blend (using the source alpha channel) the RGB values; | |
| 165 leave destination alpha untouched. [Note: is this correct?] | |
| 166 SDL_SRCCOLORKEY ignored. | |
| 167 SDL_SRCALPHA not set: | |
| 168 copy all of RGBA to the destination. | |
| 169 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 170 RGB values of the source colour key, ignoring alpha in the | |
| 171 comparison. | |
| 172 | |
| 173 RGB->RGB: | |
| 174 SDL_SRCALPHA set: | |
| 175 alpha-blend (using the source per-surface alpha value). | |
| 176 SDL_SRCALPHA not set: | |
| 177 copy RGB. | |
| 178 both: | |
| 179 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 180 source colour key. | |
| 181 | |
| 182 As a special case, blits from surfaces with per-surface alpha | |
| 183 value of 128 (50% transparency) are optimised and much faster | |
| 184 than other alpha values. This does not apply to surfaces with | |
| 185 alpha channels (per-pixel alpha). | |
| 186 | |
| 187 New functions for manipulating the gamma of the display have | |
| 188 been added: | |
| 189 int SDL_SetGamma(float red, float green, float blue); | |
| 190 int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 191 int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 192 Gamma ramps are tables with 256 entries which map the screen color | |
| 193 components into actually displayed colors. For an example of | |
| 194 implementing gamma correction and gamma fades, see test/testgamma.c | |
| 195 Gamma control is not supported on all hardware. | |
| 196 | |
| 197 1.1.4: | |
| 198 The size of the SDL_CDtrack structure changed from 8 to 12 bytes | |
| 199 as the size of the length member was extended to 32 bits. | |
| 200 | |
| 201 You can now use SDL for 2D blitting with a GL mode by passing the | |
| 202 SDL_OPENGLBLIT flag to SDL_SetVideoMode(). You can specify 16 or | |
| 203 32 bpp, and the data in the framebuffer is put into the GL scene | |
| 204 when you call SDL_UpdateRects(), and the scene will be visible | |
| 205 when you call SDL_GL_SwapBuffers(). | |
| 206 | |
| 207 Run the "testgl" test program with the -logo command line option | |
| 208 to see an example of this blending of 2D and 3D in SDL. | |
| 209 | |
| 210 1.1.3: | |
| 211 Added SDL_FreeRW() to the API, to complement SDL_AllocRW() | |
| 212 | |
| 213 Added resizable window support - just add SDL_RESIZABLE to the | |
| 214 SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events. | |
| 215 See SDL_events.h for details on the new SDL_ResizeEvent structure. | |
| 216 | |
| 217 Added condition variable support, based on mutexes and semaphores. | |
| 218 SDL_CreateCond() | |
| 219 SDL_DestroyCond() | |
| 220 SDL_CondSignal() | |
| 221 SDL_CondBroadcast() | |
| 222 SDL_CondWait() | |
| 223 SDL_CondTimedWait() | |
| 224 The new function prototypes are in SDL_mutex.h | |
| 225 | |
| 226 Added counting semaphore support, based on the mutex primitive. | |
| 227 SDL_CreateSemaphore() | |
| 228 SDL_DestroySemaphore() | |
| 229 SDL_SemWait() | |
| 230 SDL_SemTryWait() | |
| 231 SDL_SemWaitTimeout() | |
| 232 SDL_SemPost() | |
| 233 SDL_SemValue() | |
| 234 The new function prototypes are in SDL_mutex.h | |
| 235 | |
| 236 Added support for asynchronous blitting. To take advantage of this, | |
| 237 you must set the SDL_ASYNCBLIT flag when setting the video mode and | |
| 238 creating surfaces that you want accelerated in this way. You must | |
| 239 lock surfaces that have this flag set, and the lock will block until | |
| 240 any queued blits have completed. | |
| 241 | |
| 242 Added YUV video overlay support. | |
| 243 The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU. | |
| 244 This function creates an overlay surface: | |
| 245 SDL_CreateYUVOverlay() | |
| 246 You must lock and unlock the overlay to get access to the data: | |
| 247 SDL_LockYUVOverlay() SDL_UnlockYUVOverlay() | |
| 248 You can then display the overlay: | |
| 249 SDL_DisplayYUVOverlay() | |
| 250 You must free the overlay when you are done using it: | |
| 251 SDL_FreeYUVOverlay() | |
| 252 See SDL_video.h for the full function prototypes. | |
| 253 | |
| 254 The joystick hat position constants have been changed: | |
| 255 Old constant New constant | |
| 256 ------------ ------------ | |
| 257 0 SDL_HAT_CENTERED | |
| 258 1 SDL_HAT_UP | |
| 259 2 SDL_HAT_RIGHTUP | |
| 260 3 SDL_HAT_RIGHT | |
| 261 4 SDL_HAT_RIGHTDOWN | |
| 262 5 SDL_HAT_DOWN | |
| 263 6 SDL_HAT_LEFTDOWN | |
| 264 7 SDL_HAT_LEFT | |
| 265 8 SDL_HAT_LEFTUP | |
| 266 The new constants are bitmasks, so you can check for the | |
| 267 individual axes like this: | |
| 268 if ( hat_position & SDL_HAT_UP ) { | |
| 269 } | |
| 270 and you'll catch left-up, up, and right-up. | |
| 271 | |
| 272 1.1.2: | |
| 273 Added multiple timer support: | |
| 274 SDL_AddTimer() and SDL_RemoveTimer() | |
| 275 | |
| 276 SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL. | |
| 277 | |
| 278 1.1.0: | |
| 279 Added initial OpenGL support. | |
| 280 First set GL attributes (such as RGB depth, alpha depth, etc.) | |
| 281 SDL_GL_SetAttribute() | |
| 282 Then call SDL_SetVideoMode() with the SDL_OPENGL flag. | |
| 283 Perform all of your normal GL drawing. | |
| 284 Finally swap the buffers with the new SDL function: | |
| 285 SDL_GL_SwapBuffers() | |
| 286 See the new 'testgl' test program for an example of using GL with SDL. | |
| 287 | |
| 288 You can load GL extension functions by using the function: | |
| 289 SDL_GL_LoadProcAddress() | |
| 290 | |
| 291 Added functions to initialize and cleanup specific SDL subsystems: | |
| 292 SDL_InitSubSystem() and SDL_QuitSubSystem() | |
| 293 | |
| 294 Added user-defined event type: | |
| 295 typedef struct { | |
| 296 Uint8 type; | |
| 297 int code; | |
| 298 void *data1; | |
| 299 void *data2; | |
| 300 } SDL_UserEvent; | |
| 301 This structure is in the "user" member of an SDL_Event. | |
| 302 | |
| 303 Added a function to push events into the event queue: | |
| 304 SDL_PushEvent() | |
| 305 | |
| 306 Example of using the new SDL user-defined events: | |
| 307 { | |
| 308 SDL_Event event; | |
| 309 | |
| 310 event.type = SDL_USEREVENT; | |
| 311 event.user.code = my_event_code; | |
| 312 event.user.data1 = significant_data; | |
| 313 event.user.data2 = 0; | |
| 314 SDL_PushEvent(&event); | |
| 315 } | |
| 316 | |
| 317 Added a function to get mouse deltas since last query: | |
| 318 SDL_GetRelativeMouseState() | |
| 319 | |
| 320 Added a boolean datatype to SDL_types.h: | |
| 321 SDL_bool = { SDL_TRUE, SDL_FALSE } | |
| 322 | |
| 323 Added a function to get the current audio status: | |
| 324 SDL_GetAudioState(); | |
| 325 It returns one of: | |
| 326 SDL_AUDIO_STOPPED, | |
| 327 SDL_AUDIO_PLAYING, | |
| 328 SDL_AUDIO_PAUSED | |
| 329 | |
| 330 Added an AAlib driver (ASCII Art) - by Stephane Peter. | |
| 331 | |
| 332 1.0.6: | |
| 333 The input grab state is reset after each call to SDL_SetVideoMode(). | |
| 334 The input is grabbed by default in fullscreen mode, and ungrabbed in | |
| 335 windowed mode. If you want to set input grab to a particular value, | |
| 336 you should set it after each call to SDL_SetVideoMode(). | |
| 337 | |
| 338 1.0.5: | |
| 339 Exposed SDL_AudioInit(), SDL_VideoInit() | |
| 340 Added SDL_AudioDriverName() and SDL_VideoDriverName() | |
| 341 | |
| 342 Added new window manager function: | |
| 343 SDL_WM_ToggleFullScreen() | |
| 344 This is currently implemented only on Linux | |
| 345 | |
| 346 The ALT-ENTER code has been removed - it's not appropriate for a | |
| 347 lib to bind keys when they aren't even emergency escape sequences. | |
| 348 | |
| 349 ALT-ENTER functionality can be implemented with the following code: | |
| 350 | |
| 351 int Handle_AltEnter(const SDL_Event *event) | |
| 352 { | |
| 353 if ( event->type == SDL_KEYDOWN ) { | |
| 354 if ( (event->key.keysym.sym == SDLK_RETURN) && | |
| 355 (event->key.keysym.mod & KMOD_ALT) ) { | |
| 356 SDL_WM_ToggleFullScreen(SDL_GetVideoSurface()); | |
| 357 return(0); | |
| 358 } | |
| 359 } | |
| 360 return(1); | |
| 361 } | |
| 362 SDL_SetEventFilter(Handle_AltEnter); | |
| 363 | |
| 364 1.0.3: | |
| 365 Under X11, if you grab the input and hide the mouse cursor, | |
| 366 the mouse will go into a "relative motion" mode where you | |
| 367 will always get relative motion events no matter how far in | |
| 368 each direction you move the mouse - relative motion is not | |
| 369 bounded by the edges of the window (though the absolute values | |
| 370 of the mouse positions are clamped by the size of the window). | |
| 371 The SVGAlib, framebuffer console, and DirectInput drivers all | |
| 372 have this behavior naturally, and the GDI and BWindow drivers | |
| 373 never go into "relative motion" mode. | |
| 374 | |
| 375 1.0.2: | |
| 376 Added a function to enable keyboard repeat: | |
| 377 SDL_EnableKeyRepeat() | |
| 378 | |
| 379 Added a function to grab the mouse and keyboard input | |
| 380 SDL_WM_GrabInput() | |
| 381 | |
| 382 Added a function to iconify the window. | |
| 383 SDL_WM_IconifyWindow() | |
| 384 If this function succeeds, the application will receive an event | |
| 385 signaling SDL_APPACTIVE event | |
| 386 | |
| 387 1.0.1: | |
| 388 Added constants to SDL_audio.h for 16-bit native byte ordering: | |
| 389 AUDIO_U16SYS, AUDIO_S16SYS | |
| 390 | |
| 391 1.0.0: | |
| 392 New public release | |
| 393 | |
| 394 Version 0.11: | |
| 395 | |
| 396 0.11.5: | |
| 397 A new function SDL_GetVideoSurface() has been added, and returns | |
| 398 a pointer to the current display surface. | |
| 399 | |
| 400 SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and | |
| 401 a new function SDL_CreateRGBSurfaceFrom() has been added to allow | |
| 402 creating an SDL surface from an existing pixel data buffer. | |
| 403 | |
| 404 Added SDL_GetRGB() to the headers and documentation. | |
| 405 | |
| 406 0.11.4: | |
| 407 SDL_SetLibraryPath() is no longer meaningful, and has been removed. | |
| 408 | |
| 409 0.11.3: | |
| 410 A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from | |
| 411 installing fatal signal handlers on operating systems that support | |
| 412 them. | |
| 413 | |
| 414 Version 0.9: | |
| 415 | |
| 416 0.9.15: | |
| 417 SDL_CreateColorCursor() has been removed. Color cursors should | |
| 418 be implemented as sprites, blitted by the application when the | |
| 419 cursor moves. To get smooth color cursor updates when the app | |
| 420 is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init(). This | |
| 421 allows you to handle the mouse motion in another thread from an | |
| 422 event filter function, but is currently only supported by Linux | |
| 423 and BeOS. Note that you'll have to protect the display surface | |
| 424 from multi-threaded access by using mutexes if you do this. | |
| 425 | |
| 426 Thread-safe surface support has been removed from SDL. | |
| 427 This makes blitting somewhat faster, by removing SDL_MiddleBlit(). | |
| 428 Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead. | |
| 429 You can make your surfaces thread-safe by allocating your own | |
| 430 mutex and making lock/unlock calls around accesses to your surface. | |
| 431 | |
| 432 0.9.14: | |
| 433 SDL_GetMouseState() now takes pointers to int rather than Uint16. | |
| 434 | |
| 435 If you set the SDL_WINDOWID environment variable under UNIX X11, | |
| 436 SDL will use that as the main window instead of creating it's own. | |
| 437 This is an unsupported extension to SDL, and not portable at all. | |
| 438 | |
| 439 0.9.13: | |
| 440 Added a function SDL_SetLibraryPath() which can be used to specify | |
| 441 the directory containing the SDL dynamic libraries. This is useful | |
| 442 for commercial applications which ship with particular versions | |
| 443 of the libraries, and for security on multi-user systems. | |
| 444 If this function is not used, the default system directories are | |
| 445 searched using the native dynamic object loading mechanism. | |
| 446 | |
| 447 In order to support C linkage under Visual C++, you must declare | |
| 448 main() without any return type: | |
| 449 main(int argc, char *argv[]) { | |
| 450 /* Do the program... */ | |
| 451 return(0); | |
| 452 } | |
| 453 C++ programs should also return a value if compiled under VC++. | |
| 454 | |
| 455 The blit_endian member of the SDL_VideoInfo struct has been removed. | |
| 456 | |
| 457 SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there | |
| 458 is now no longer any function to translate a keysym to a character. | |
| 459 | |
| 460 The SDL_keysym structure has been extended with a 'scancode' and | |
| 461 'unicode' member. The 'scancode' is a hardware specific scancode | |
| 462 for the key that was pressed, and may be 0. The 'unicode' member | |
| 463 is a 16-bit UNICODE translation of the key that was pressed along | |
| 464 with any modifiers or compose keys that have been pressed. | |
| 465 If no UNICODE translation exists for the key, 'unicode' will be 0. | |
| 466 | |
| 467 Added a function SDL_EnableUNICODE() to enable/disable UNICODE | |
| 468 translation of character keypresses. Translation defaults off. | |
| 469 | |
| 470 To convert existing code to use the new API, change code which | |
| 471 uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(), | |
| 472 and change code which uses it to get the ASCII value of a sym to | |
| 473 use the 'unicode' member of the event keysym. | |
| 474 | |
| 475 0.9.12: | |
| 476 There is partial support for 64-bit datatypes. I don't recommend | |
| 477 you use this if you have a choice, because 64-bit datatypes are not | |
| 478 supported on many platforms. On platforms for which it is supported, | |
| 479 the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and | |
| 480 you can use the Uint64 and Sint64 datatypes. | |
| 481 | |
| 482 Added functions to SDL_endian.h to support 64-bit datatypes: | |
| 483 SDL_SwapLE64(), SDL_SwapBE64(), | |
| 484 SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64() | |
| 485 | |
| 486 A new member "len_ratio" has been added to the SDL_AudioCVT structure, | |
| 487 and allows you to determine either the original buffer length or the | |
| 488 converted buffer length, given the other. | |
| 489 | |
| 490 A new function SDL_FreeWAV() has been added to the API to free data | |
| 491 allocated by SDL_LoadWAV_RW(). This is necessary under Win32 since | |
| 492 the gcc compiled DLL uses a different heap than VC++ compiled apps. | |
| 493 | |
| 494 SDL now has initial support for international keyboards using the | |
| 495 Latin character set. | |
| 496 If a particular mapping is desired, you can set the DEFAULT_KEYBOARD | |
| 497 compile-time variable, or you can set the environment variable | |
| 498 "SDL_KEYBOARD" to a string identifying the keyboard mapping you desire. | |
| 499 The valid values for these variables can be found in SDL_keyboard.c | |
| 500 | |
| 501 Full support for German and French keyboards under X11 is implemented. | |
| 502 | |
| 503 0.9.11: | |
| 504 The THREADED_EVENTS compile-time define has been replaced with the | |
| 505 SDL_INIT_EVENTTHREAD flag. If this flag is passed to SDL_Init(), | |
| 506 SDL will create a separate thread to perform input event handling. | |
| 507 If this flag is passed to SDL_Init(), and the OS doesn't support | |
| 508 event handling in a separate thread, SDL_Init() will fail. | |
| 509 Be sure to add calls to SDL_Delay() in your main thread to allow | |
| 510 the OS to schedule your event thread, or it may starve, leading | |
| 511 to slow event delivery and/or dropped events. | |
| 512 Currently MacOS and Win32 do not support this flag, while BeOS | |
| 513 and Linux do support it. I recommend that your application only | |
| 514 use this flag if absolutely necessary. | |
| 515 | |
| 516 The SDL thread function passed to SDL_CreateThread() now returns a | |
| 517 status. This status can be retrieved by passing a non-NULL pointer | |
| 518 as the 'status' argument to SDL_WaitThread(). | |
| 519 | |
| 520 The volume parameter to SDL_MixAudio() has been increased in range | |
| 521 from (0-8) to (0-128) | |
| 522 | |
| 523 SDL now has a data source abstraction which can encompass a file, | |
| 524 an area of memory, or any custom object you can envision. It uses | |
| 525 these abstractions, SDL_RWops, in the endian read/write functions, | |
| 526 and the built-in WAV and BMP file loaders. This means you can load | |
| 527 WAV chunks from memory mapped files, compressed archives, network | |
| 528 pipes, or anything else that has a data read abstraction. | |
| 529 | |
| 530 There are three built-in data source abstractions: | |
| 531 SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem() | |
| 532 along with a generic data source allocation function: | |
| 533 SDL_AllocRW() | |
| 534 These data sources can be used like stdio file pointers with the | |
| 535 following convenience functions: | |
| 536 SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose() | |
| 537 These functions are defined in the new header file "SDL_rwops.h" | |
| 538 | |
| 539 The endian swapping functions have been turned into macros for speed | |
| 540 and SDL_CalculateEndian() has been removed. SDL_endian.h now defines | |
| 541 SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on | |
| 542 the endianness of the host system. | |
| 543 | |
| 544 The endian read/write functions now take an SDL_RWops pointer | |
| 545 instead of a stdio FILE pointer, to support the new data source | |
| 546 abstraction. | |
| 547 | |
| 548 The SDL_*LoadWAV() functions have been replaced with a single | |
| 549 SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's | |
| 550 first parameter, and a flag whether or not to automatically | |
| 551 free it as the second parameter. SDL_LoadWAV() is a macro for | |
| 552 backward compatibility and convenience: | |
| 553 SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...); | |
| 554 | |
| 555 The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced | |
| 556 with a single function that takes a SDL_RWops pointer as it's | |
| 557 first parameter, and a flag whether or not to automatically | |
| 558 free it as the second parameter. SDL_LoadBMP() and SDL_SaveBMP() | |
| 559 are macros for backward compatibility and convenience: | |
| 560 SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...); | |
| 561 SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...); | |
| 562 Note that these functions use SDL_RWseek() extensively, and should | |
| 563 not be used on pipes or other non-seekable data sources. | |
| 564 | |
| 565 0.9.10: | |
| 566 The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been | |
| 567 extended to support multiple types of display drivers, as well as | |
| 568 safe access to the X11 display when THREADED_EVENTS is enabled. | |
| 569 The new structures are documented in the SDL_syswm.h header file. | |
| 570 | |
| 571 Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard | |
| 572 should now work properly, as well as the "Windows" keys on US | |
| 573 keyboards. | |
| 574 | |
| 575 The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab | |
| 576 instead of trying to open each block device on the system. | |
| 577 The CD must be listed in /etc/fstab as using the iso9660 filesystem. | |
| 578 | |
| 579 On Linux, if you define THREADED_EVENTS at compile time, a separate | |
| 580 thread will be spawned to gather X events asynchronously from the | |
| 581 graphics updates. This hasn't been extensively tested, but it does | |
| 582 provide a means of handling keyboard and mouse input in a separate | |
| 583 thread from the graphics thread. (This is now enabled by default.) | |
| 584 | |
| 585 A special access function SDL_PeepEvents() allows you to manipulate | |
| 586 the event queue in a thread-safe manner, including peeking at events, | |
| 587 removing events of a specified type, and adding new events of arbitrary | |
| 588 type to the queue (use the new 'user' member of the SDL_Event type). | |
| 589 | |
| 590 If you use SDL_PeepEvents() to gather events, then the main graphics | |
| 591 thread needs to call SDL_PumpEvents() periodically to drive the event | |
| 592 loop and generate input events. This is not necessary if SDL has been | |
| 593 compiled with THREADED_EVENTS defined, but doesn't hurt. | |
| 594 | |
| 595 A new function SDL_ThreadID() returns the identifier associated with | |
| 596 the current thread. | |
| 597 | |
| 598 0.9.9: | |
| 599 The AUDIO_STEREO format flag has been replaced with a new 'channels' | |
| 600 member of the SDL_AudioSpec structure. The channels are 1 for mono | |
| 601 audio, and 2 for stereo audio. In the future more channels may be | |
| 602 supported for 3D surround sound. | |
| 603 | |
| 604 The SDL_MixAudio() function now takes an additional volume parameter, | |
| 605 which should be set to SDL_MIX_MAXVOLUME for compatibility with the | |
| 606 original function. | |
| 607 | |
| 608 The CD-ROM functions which take a 'cdrom' parameter can now be | |
| 609 passed NULL, and will act on the last successfully opened CD-ROM. | |
| 610 | |
| 611 0.9.8: | |
| 612 No changes, bugfixes only. | |
| 613 | |
| 614 0.9.7: | |
| 615 No changes, bugfixes only. | |
| 616 | |
| 617 0.9.6: | |
| 618 Added a fast rectangle fill function: SDL_FillRect() | |
| 619 | |
| 620 Addition of a useful function for getting info on the video hardware: | |
| 621 const SDL_VideoInfo *SDL_GetVideoInfo(void) | |
| 622 This function replaces SDL_GetDisplayFormat(). | |
| 623 | |
| 624 Initial support for double-buffering: | |
| 625 Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode() | |
| 626 Update the screen with a new function: SDL_Flip() | |
| 627 | |
| 628 SDL_AllocSurface() takes two new flags: | |
| 629 SDL_SRCCOLORKEY means that the surface will be used for colorkey blits | |
| 630 and if the hardware supports hardware acceleration of colorkey blits | |
| 631 between two surfaces in video memory, to place the surface in video | |
| 632 memory if possible, otherwise it will be placed in system memory. | |
| 633 SDL_SRCALPHA means that the surface will be used for alpha blits and | |
| 634 if the hardware supports hardware acceleration of alpha blits between | |
| 635 two surfaces in video memory, to place the surface in video memory | |
| 636 if possible, otherwise it will be placed in system memory. | |
| 637 SDL_HWSURFACE now means that the surface will be created with the | |
| 638 same format as the display surface, since having surfaces in video | |
| 639 memory is only useful for fast blitting to the screen, and you can't | |
| 640 blit surfaces with different surface formats in video memory. | |
| 641 | |
| 642 0.9.5: | |
| 643 You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume | |
| 644 that the icon consists of the entire image. | |
| 645 | |
| 646 SDL_LowerBlit() is back -- but don't use it on the display surface. | |
| 647 It is exactly the same as SDL_MiddleBlit(), but doesn't check for | |
| 648 thread safety. | |
| 649 | |
| 650 Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take | |
| 651 a FILE pointer instead of a file name. | |
| 652 | |
| 653 Added CD-ROM audio control API: | |
| 654 SDL_CDNumDrives() | |
| 655 SDL_CDName() | |
| 656 SDL_CDOpen() | |
| 657 SDL_CDStatus() | |
| 658 SDL_CDPlayTracks() | |
| 659 SDL_CDPlay() | |
| 660 SDL_CDPause() | |
| 661 SDL_CDResume() | |
| 662 SDL_CDStop() | |
| 663 SDL_CDEject() | |
| 664 SDL_CDClose() | |
| 665 | |
| 666 0.9.4: | |
| 667 No changes, bugfixes only. | |
| 668 | |
| 669 0.9.3: | |
| 670 Mouse motion event now includes relative motion information: | |
| 671 Sint16 event->motion.xrel, Sint16 event->motion.yrel | |
| 672 | |
| 673 X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT | |
| 674 (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile) | |
| 675 | |
| 676 0.9.2: | |
| 677 No changes, bugfixes only. | |
| 678 | |
| 679 0.9.1: | |
| 680 Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now | |
| 681 automatically mapped on blit. | |
| 682 | |
| 683 0.8.0: | |
| 684 SDL stable release |
