Subject: SDL OSX fullscreen FIX
the attached patch fixes the fullscreen problems on SDL/OSX. The cause
was that click events are bounded by winRect. Now, winRect is set to
the size of the video surface. But if you e.g. request a 640x420
surface, you might get a 640x480 "real" surface. Still,
SDL_VideoSurface->h will be set to 420! Thus, the upper 60 pixels in my
example received no mouse down events.
My fix simply disables this clipping when in full screen mode - after
all, all clicks then should be inside the screen surface. Higher SDL
functions ensure that the coordinates then are clipped to 640x420. It
works fine in all my tests here. I don't know if it's the right thing
to do in multi screen scenarios, though.

| 0 | 16 1.2.0: |
| 17 Added SDL_VIDEOEXPOSE event to signal that the screen needs to | |
| 18 be redrawn. This is currently only delivered to OpenGL windows | |
| 19 on X11, though it may be delivered in the future when the video | |
| 20 memory is lost under DirectX. | |
| 21 | |
| 22 1.1.8: | |
| 23 You can pass SDL_NOFRAME to SDL_VideoMode() to create a window | |
| 24 that has no title bar or frame decoration. Fullscreen video | |
| 25 modes automatically have this flag set. | |
| 26 | |
| 27 Added a function to query the clipping rectangle for a surface: | |
| 28 void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 29 | |
| 30 Added a function to query the current event filter: | |
| 31 SDL_EventFilter SDL_GetEventFilter(void) | |
| 32 | |
| 33 If you pass -1 to SDL_ShowCursor(), it won't change the current | |
| 34 cursor visibility state, but will still return it. | |
| 35 | |
| 36 SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning | |
| 37 you can nest them as deep as you want, as long as each lock call | |
| 38 has a matching unlock call. The surface remains locked until the | |
| 39 last matching unlock call. | |
| 40 | |
| 41 Note that you may not blit to or from a locked surface. | |
| 42 | |
| 43 1.1.7: | |
| 44 The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take | |
| 45 arrays of Uint16 values instead of Uint8 values. For the most part, | |
| 46 you can just take your old values and shift them up 8 bits to get | |
| 47 new correct values for your gamma ramps. | |
| 48 | |
| 49 You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface() | |
| 50 and SDL will try to RLE accelerate colorkey and alpha blits in the | |
| 51 resulting surface. | |
| 52 | |
| 53 1.1.6: | |
| 54 Added a function to return the thread ID of a specific thread: | |
| 55 Uint32 SDL_GetThreadID(SDL_Thread *thread) | |
| 56 If 'thread' is NULL, this function returns the id for this thread. | |
| 57 | |
| 58 1.1.5: | |
| 59 The YUV overlay structure has been changed to use an array of | |
| 60 pitches and pixels representing the planes of a YUV image, to | |
| 61 better enable hardware acceleration. The YV12 and IYUV formats | |
| 62 each have three planes, corresponding to the Y, U, and V portions | |
| 63 of the image, while packed pixel YUV formats just have one plane. | |
| 64 | |
| 65 For palettized mode (8bpp), the screen colormap is now split in | |
| 66 a physical and a logical palette. The physical palette determines | |
| 67 what colours the screen pixels will get when displayed, and the | |
| 68 logical palette controls the mapping from blits to/from the screen. | |
| 69 A new function, SDL_SetPalette() has been added to change | |
| 70 logical and physical palettes separately. SDL_SetColors() works | |
| 71 just as before, and is equivalent to calling SDL_SetPalette() with | |
| 72 a flag argument of (SDL_LOGPAL|SDL_PHYSPAL). | |
| 73 | |
| 74 SDL_BlitSurface() no longer modifies the source rectangle, only the | |
| 75 destination rectangle. The width/height members of the destination | |
| 76 rectangle are ignored, only the position is used. | |
| 77 | |
| 78 The old source clipping function SDL_SetClipping() has been replaced | |
| 79 with a more useful function to set the destination clipping rectangle: | |
| 80 SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 81 | |
| 82 Added a function to see what subsystems have been initialized: | |
| 83 Uint32 SDL_WasInit(Uint32 flags) | |
| 84 | |
| 85 The Big Alpha Flip: SDL now treats alpha as opacity like everybody | |
| 86 else, and not as transparency: | |
| 87 | |
| 88 A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255 | |
| 89 A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0 | |
| 90 Values between 0 and 255 vary from fully transparent to fully opaque. | |
| 91 | |
| 92 New functions: | |
| 93 SDL_DisplayFormatAlpha() | |
| 94 Returns a surface converted to a format with alpha-channel | |
| 95 that can be blit efficiently to the screen. (In other words, | |
| 96 like SDL_DisplayFormat() but the resulting surface has | |
| 97 an alpha channel.) This is useful for surfaces with alpha. | |
| 98 SDL_MapRGBA() | |
| 99 Works as SDL_MapRGB() but takes an additional alpha parameter. | |
| 100 SDL_GetRGBA() | |
| 101 Works as SDL_GetRGB() but also returns the alpha value | |
| 102 (SDL_ALPHA_OPAQUE for formats without an alpha channel) | |
| 103 | |
| 104 Both SDL_GetRGB() and SDL_GetRGBA() now always return values in | |
| 105 the [0..255] interval. Previously, SDL_GetRGB() would return | |
| 106 (0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format. | |
| 107 (N.B.: This is broken for bit fields < 3 bits.) | |
| 108 | |
| 109 SDL_MapRGB() returns pixels in which the alpha channel is set opaque. | |
| 110 | |
| 111 SDL_SetAlpha() can now be used for both setting the per-surface | |
| 112 alpha, using the new way of thinking of alpha, and also to enable | |
| 113 and disable per-pixel alpha blending for surfaces with an alpha | |
| 114 channel: | |
| 115 To disable alpha blending: | |
| 116 SDL_SetAlpha(surface, 0, 0); | |
| 117 To re-enable alpha blending: | |
| 118 SDL_SetAlpha(surface, SDL_SRCALPHA, 0); | |
| 119 Surfaces with an alpha channel have blending enabled by default. | |
| 120 | |
| 121 SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests | |
| 122 RLE acceleration of blits, just as like with SDL_SetColorKey(). | |
| 123 This flag can be set for both surfaces with an alpha channel | |
| 124 and surfaces with an alpha value set by SDL_SetAlpha(). | |
| 125 As always, RLE surfaces must be locked before pixel access is | |
| 126 allowed, and unlocked before any other SDL operations are done | |
| 127 on it. | |
| 128 | |
| 129 The blit semantics for surfaces with and without alpha and colorkey | |
| 130 have now been defined: | |
| 131 | |
| 132 RGBA->RGB: | |
| 133 SDL_SRCALPHA set: | |
| 134 alpha-blend (using alpha-channel). | |
| 135 SDL_SRCCOLORKEY ignored. | |
| 136 SDL_SRCALPHA not set: | |
| 137 copy RGB. | |
| 138 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 139 RGB values of the source colour key, ignoring alpha in the | |
| 140 comparison. | |
| 141 | |
| 142 RGB->RGBA: | |
| 143 SDL_SRCALPHA set: | |
| 144 alpha-blend (using the source per-surface alpha value); | |
| 145 set destination alpha to opaque. | |
| 146 SDL_SRCALPHA not set: | |
| 147 copy RGB, set destination alpha to opaque. | |
| 148 both: | |
| 149 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 150 source colour key. | |
| 151 | |
| 152 RGBA->RGBA: | |
| 153 SDL_SRCALPHA set: | |
| 154 alpha-blend (using the source alpha channel) the RGB values; | |
| 155 leave destination alpha untouched. [Note: is this correct?] | |
| 156 SDL_SRCCOLORKEY ignored. | |
| 157 SDL_SRCALPHA not set: | |
| 158 copy all of RGBA to the destination. | |
| 159 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 160 RGB values of the source colour key, ignoring alpha in the | |
| 161 comparison. | |
| 162 | |
| 163 RGB->RGB: | |
| 164 SDL_SRCALPHA set: | |
| 165 alpha-blend (using the source per-surface alpha value). | |
| 166 SDL_SRCALPHA not set: | |
| 167 copy RGB. | |
| 168 both: | |
| 169 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 170 source colour key. | |
| 171 | |
| 172 As a special case, blits from surfaces with per-surface alpha | |
| 173 value of 128 (50% transparency) are optimised and much faster | |
| 174 than other alpha values. This does not apply to surfaces with | |
| 175 alpha channels (per-pixel alpha). | |
| 176 | |
| 177 New functions for manipulating the gamma of the display have | |
| 178 been added: | |
| 179 int SDL_SetGamma(float red, float green, float blue); | |
| 180 int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 181 int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 182 Gamma ramps are tables with 256 entries which map the screen color | |
| 183 components into actually displayed colors. For an example of | |
| 184 implementing gamma correction and gamma fades, see test/testgamma.c | |
| 185 Gamma control is not supported on all hardware. | |
| 186 | |
| 187 1.1.4: | |
| 188 The size of the SDL_CDtrack structure changed from 8 to 12 bytes | |
| 189 as the size of the length member was extended to 32 bits. | |
| 190 | |
| 191 You can now use SDL for 2D blitting with a GL mode by passing the | |
| 192 SDL_OPENGLBLIT flag to SDL_SetVideoMode(). You can specify 16 or | |
| 193 32 bpp, and the data in the framebuffer is put into the GL scene | |
| 194 when you call SDL_UpdateRects(), and the scene will be visible | |
| 195 when you call SDL_GL_SwapBuffers(). | |
| 196 | |
| 197 Run the "testgl" test program with the -logo command line option | |
| 198 to see an example of this blending of 2D and 3D in SDL. | |
| 199 | |
| 200 1.1.3: | |
| 201 Added SDL_FreeRW() to the API, to complement SDL_AllocRW() | |
| 202 | |
| 203 Added resizable window support - just add SDL_RESIZABLE to the | |
| 204 SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events. | |
| 205 See SDL_events.h for details on the new SDL_ResizeEvent structure. | |
| 206 | |
| 207 Added condition variable support, based on mutexes and semaphores. | |
| 208 SDL_CreateCond() | |
| 209 SDL_DestroyCond() | |
| 210 SDL_CondSignal() | |
| 211 SDL_CondBroadcast() | |
| 212 SDL_CondWait() | |
| 213 SDL_CondTimedWait() | |
| 214 The new function prototypes are in SDL_mutex.h | |
| 215 | |
| 216 Added counting semaphore support, based on the mutex primitive. | |
| 217 SDL_CreateSemaphore() | |
| 218 SDL_DestroySemaphore() | |
| 219 SDL_SemWait() | |
| 220 SDL_SemTryWait() | |
| 221 SDL_SemWaitTimeout() | |
| 222 SDL_SemPost() | |
| 223 SDL_SemValue() | |
| 224 The new function prototypes are in SDL_mutex.h | |
| 225 | |
| 226 Added support for asynchronous blitting. To take advantage of this, | |
| 227 you must set the SDL_ASYNCBLIT flag when setting the video mode and | |
| 228 creating surfaces that you want accelerated in this way. You must | |
| 229 lock surfaces that have this flag set, and the lock will block until | |
| 230 any queued blits have completed. | |
| 231 | |
| 232 Added YUV video overlay support. | |
| 233 The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU. | |
| 234 This function creates an overlay surface: | |
| 235 SDL_CreateYUVOverlay() | |
| 236 You must lock and unlock the overlay to get access to the data: | |
| 237 SDL_LockYUVOverlay() SDL_UnlockYUVOverlay() | |
| 238 You can then display the overlay: | |
| 239 SDL_DisplayYUVOverlay() | |
| 240 You must free the overlay when you are done using it: | |
| 241 SDL_FreeYUVOverlay() | |
| 242 See SDL_video.h for the full function prototypes. | |
| 243 | |
| 244 The joystick hat position constants have been changed: | |
| 245 Old constant New constant | |
| 246 ------------ ------------ | |
| 247 0 SDL_HAT_CENTERED | |
| 248 1 SDL_HAT_UP | |
| 249 2 SDL_HAT_RIGHTUP | |
| 250 3 SDL_HAT_RIGHT | |
| 251 4 SDL_HAT_RIGHTDOWN | |
| 252 5 SDL_HAT_DOWN | |
| 253 6 SDL_HAT_LEFTDOWN | |
| 254 7 SDL_HAT_LEFT | |
| 255 8 SDL_HAT_LEFTUP | |
| 256 The new constants are bitmasks, so you can check for the | |
| 257 individual axes like this: | |
| 258 if ( hat_position & SDL_HAT_UP ) { | |
| 259 } | |
| 260 and you'll catch left-up, up, and right-up. | |
| 261 | |
| 262 1.1.2: | |
| 263 Added multiple timer support: | |
| 264 SDL_AddTimer() and SDL_RemoveTimer() | |
| 265 | |
| 266 SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL. | |
| 267 | |
| 268 1.1.0: | |
| 269 Added initial OpenGL support. | |
| 270 First set GL attributes (such as RGB depth, alpha depth, etc.) | |
| 271 SDL_GL_SetAttribute() | |
| 272 Then call SDL_SetVideoMode() with the SDL_OPENGL flag. | |
| 273 Perform all of your normal GL drawing. | |
| 274 Finally swap the buffers with the new SDL function: | |
| 275 SDL_GL_SwapBuffers() | |
| 276 See the new 'testgl' test program for an example of using GL with SDL. | |
| 277 | |
| 278 You can load GL extension functions by using the function: | |
| 279 SDL_GL_LoadProcAddress() | |
| 280 | |
| 281 Added functions to initialize and cleanup specific SDL subsystems: | |
| 282 SDL_InitSubSystem() and SDL_QuitSubSystem() | |
| 283 | |
| 284 Added user-defined event type: | |
| 285 typedef struct { | |
| 286 Uint8 type; | |
| 287 int code; | |
| 288 void *data1; | |
| 289 void *data2; | |
| 290 } SDL_UserEvent; | |
| 291 This structure is in the "user" member of an SDL_Event. | |
| 292 | |
| 293 Added a function to push events into the event queue: | |
| 294 SDL_PushEvent() | |
| 295 | |
| 296 Example of using the new SDL user-defined events: | |
| 297 { | |
| 298 SDL_Event event; | |
| 299 | |
| 300 event.type = SDL_USEREVENT; | |
| 301 event.user.code = my_event_code; | |
| 302 event.user.data1 = significant_data; | |
| 303 event.user.data2 = 0; | |
| 304 SDL_PushEvent(&event); | |
| 305 } | |
| 306 | |
| 307 Added a function to get mouse deltas since last query: | |
| 308 SDL_GetRelativeMouseState() | |
| 309 | |
| 310 Added a boolean datatype to SDL_types.h: | |
| 311 SDL_bool = { SDL_TRUE, SDL_FALSE } | |
| 312 | |
| 313 Added a function to get the current audio status: | |
| 314 SDL_GetAudioState(); | |
| 315 It returns one of: | |
| 316 SDL_AUDIO_STOPPED, | |
| 317 SDL_AUDIO_PLAYING, | |
| 318 SDL_AUDIO_PAUSED | |
| 319 | |
| 320 Added an AAlib driver (ASCII Art) - by Stephane Peter. | |
| 321 | |
| 322 1.0.6: | |
| 323 The input grab state is reset after each call to SDL_SetVideoMode(). | |
| 324 The input is grabbed by default in fullscreen mode, and ungrabbed in | |
| 325 windowed mode. If you want to set input grab to a particular value, | |
| 326 you should set it after each call to SDL_SetVideoMode(). | |
| 327 | |
| 328 1.0.5: | |
| 329 Exposed SDL_AudioInit(), SDL_VideoInit() | |
| 330 Added SDL_AudioDriverName() and SDL_VideoDriverName() | |
| 331 | |
| 332 Added new window manager function: | |
| 333 SDL_WM_ToggleFullScreen() | |
| 334 This is currently implemented only on Linux | |
| 335 | |
| 336 The ALT-ENTER code has been removed - it's not appropriate for a | |
| 337 lib to bind keys when they aren't even emergency escape sequences. | |
| 338 | |
| 339 ALT-ENTER functionality can be implemented with the following code: | |
| 340 | |
| 341 int Handle_AltEnter(const SDL_Event *event) | |
| 342 { | |
| 343 if ( event->type == SDL_KEYDOWN ) { | |
| 344 if ( (event->key.keysym.sym == SDLK_RETURN) && | |
| 345 (event->key.keysym.mod & KMOD_ALT) ) { | |
| 346 SDL_WM_ToggleFullScreen(SDL_GetVideoSurface()); | |
| 347 return(0); | |
| 348 } | |
| 349 } | |
| 350 return(1); | |
| 351 } | |
| 352 SDL_SetEventFilter(Handle_AltEnter); | |
| 353 | |
| 354 1.0.3: | |
| 355 Under X11, if you grab the input and hide the mouse cursor, | |
| 356 the mouse will go into a "relative motion" mode where you | |
| 357 will always get relative motion events no matter how far in | |
| 358 each direction you move the mouse - relative motion is not | |
| 359 bounded by the edges of the window (though the absolute values | |
| 360 of the mouse positions are clamped by the size of the window). | |
| 361 The SVGAlib, framebuffer console, and DirectInput drivers all | |
| 362 have this behavior naturally, and the GDI and BWindow drivers | |
| 363 never go into "relative motion" mode. | |
| 364 | |
| 365 1.0.2: | |
| 366 Added a function to enable keyboard repeat: | |
| 367 SDL_EnableKeyRepeat() | |
| 368 | |
| 369 Added a function to grab the mouse and keyboard input | |
| 370 SDL_WM_GrabInput() | |
| 371 | |
| 372 Added a function to iconify the window. | |
| 373 SDL_WM_IconifyWindow() | |
| 374 If this function succeeds, the application will receive an event | |
| 375 signaling SDL_APPACTIVE event | |
| 376 | |
| 377 1.0.1: | |
| 378 Added constants to SDL_audio.h for 16-bit native byte ordering: | |
| 379 AUDIO_U16SYS, AUDIO_S16SYS | |
| 380 | |
| 381 1.0.0: | |
| 382 New public release | |
| 383 | |
| 384 Version 0.11: | |
| 385 | |
| 386 0.11.5: | |
| 387 A new function SDL_GetVideoSurface() has been added, and returns | |
| 388 a pointer to the current display surface. | |
| 389 | |
| 390 SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and | |
| 391 a new function SDL_CreateRGBSurfaceFrom() has been added to allow | |
| 392 creating an SDL surface from an existing pixel data buffer. | |
| 393 | |
| 394 Added SDL_GetRGB() to the headers and documentation. | |
| 395 | |
| 396 0.11.4: | |
| 397 SDL_SetLibraryPath() is no longer meaningful, and has been removed. | |
| 398 | |
| 399 0.11.3: | |
| 400 A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from | |
| 401 installing fatal signal handlers on operating systems that support | |
| 402 them. | |
| 403 | |
| 404 Version 0.9: | |
| 405 | |
| 406 0.9.15: | |
| 407 SDL_CreateColorCursor() has been removed. Color cursors should | |
| 408 be implemented as sprites, blitted by the application when the | |
| 409 cursor moves. To get smooth color cursor updates when the app | |
| 410 is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init(). This | |
| 411 allows you to handle the mouse motion in another thread from an | |
| 412 event filter function, but is currently only supported by Linux | |
| 413 and BeOS. Note that you'll have to protect the display surface | |
| 414 from multi-threaded access by using mutexes if you do this. | |
| 415 | |
| 416 Thread-safe surface support has been removed from SDL. | |
| 417 This makes blitting somewhat faster, by removing SDL_MiddleBlit(). | |
| 418 Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead. | |
| 419 You can make your surfaces thread-safe by allocating your own | |
| 420 mutex and making lock/unlock calls around accesses to your surface. | |
| 421 | |
| 422 0.9.14: | |
| 423 SDL_GetMouseState() now takes pointers to int rather than Uint16. | |
| 424 | |
| 425 If you set the SDL_WINDOWID environment variable under UNIX X11, | |
| 426 SDL will use that as the main window instead of creating it's own. | |
| 427 This is an unsupported extension to SDL, and not portable at all. | |
| 428 | |
| 429 0.9.13: | |
| 430 Added a function SDL_SetLibraryPath() which can be used to specify | |
| 431 the directory containing the SDL dynamic libraries. This is useful | |
| 432 for commercial applications which ship with particular versions | |
| 433 of the libraries, and for security on multi-user systems. | |
| 434 If this function is not used, the default system directories are | |
| 435 searched using the native dynamic object loading mechanism. | |
| 436 | |
| 437 In order to support C linkage under Visual C++, you must declare | |
| 438 main() without any return type: | |
| 439 main(int argc, char *argv[]) { | |
| 440 /* Do the program... */ | |
| 441 return(0); | |
| 442 } | |
| 443 C++ programs should also return a value if compiled under VC++. | |
| 444 | |
| 445 The blit_endian member of the SDL_VideoInfo struct has been removed. | |
| 446 | |
| 447 SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there | |
| 448 is now no longer any function to translate a keysym to a character. | |
| 449 | |
| 450 The SDL_keysym structure has been extended with a 'scancode' and | |
| 451 'unicode' member. The 'scancode' is a hardware specific scancode | |
| 452 for the key that was pressed, and may be 0. The 'unicode' member | |
| 453 is a 16-bit UNICODE translation of the key that was pressed along | |
| 454 with any modifiers or compose keys that have been pressed. | |
| 455 If no UNICODE translation exists for the key, 'unicode' will be 0. | |
| 456 | |
| 457 Added a function SDL_EnableUNICODE() to enable/disable UNICODE | |
| 458 translation of character keypresses. Translation defaults off. | |
| 459 | |
| 460 To convert existing code to use the new API, change code which | |
| 461 uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(), | |
| 462 and change code which uses it to get the ASCII value of a sym to | |
| 463 use the 'unicode' member of the event keysym. | |
| 464 | |
| 465 0.9.12: | |
| 466 There is partial support for 64-bit datatypes. I don't recommend | |
| 467 you use this if you have a choice, because 64-bit datatypes are not | |
| 468 supported on many platforms. On platforms for which it is supported, | |
| 469 the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and | |
| 470 you can use the Uint64 and Sint64 datatypes. | |
| 471 | |
| 472 Added functions to SDL_endian.h to support 64-bit datatypes: | |
| 473 SDL_SwapLE64(), SDL_SwapBE64(), | |
| 474 SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64() | |
| 475 | |
| 476 A new member "len_ratio" has been added to the SDL_AudioCVT structure, | |
| 477 and allows you to determine either the original buffer length or the | |
| 478 converted buffer length, given the other. | |
| 479 | |
| 480 A new function SDL_FreeWAV() has been added to the API to free data | |
| 481 allocated by SDL_LoadWAV_RW(). This is necessary under Win32 since | |
| 482 the gcc compiled DLL uses a different heap than VC++ compiled apps. | |
| 483 | |
| 484 SDL now has initial support for international keyboards using the | |
| 485 Latin character set. | |
| 486 If a particular mapping is desired, you can set the DEFAULT_KEYBOARD | |
| 487 compile-time variable, or you can set the environment variable | |
| 488 "SDL_KEYBOARD" to a string identifying the keyboard mapping you desire. | |
| 489 The valid values for these variables can be found in SDL_keyboard.c | |
| 490 | |
| 491 Full support for German and French keyboards under X11 is implemented. | |
| 492 | |
| 493 0.9.11: | |
| 494 The THREADED_EVENTS compile-time define has been replaced with the | |
| 495 SDL_INIT_EVENTTHREAD flag. If this flag is passed to SDL_Init(), | |
| 496 SDL will create a separate thread to perform input event handling. | |
| 497 If this flag is passed to SDL_Init(), and the OS doesn't support | |
| 498 event handling in a separate thread, SDL_Init() will fail. | |
| 499 Be sure to add calls to SDL_Delay() in your main thread to allow | |
| 500 the OS to schedule your event thread, or it may starve, leading | |
| 501 to slow event delivery and/or dropped events. | |
| 502 Currently MacOS and Win32 do not support this flag, while BeOS | |
| 503 and Linux do support it. I recommend that your application only | |
| 504 use this flag if absolutely necessary. | |
| 505 | |
| 506 The SDL thread function passed to SDL_CreateThread() now returns a | |
| 507 status. This status can be retrieved by passing a non-NULL pointer | |
| 508 as the 'status' argument to SDL_WaitThread(). | |
| 509 | |
| 510 The volume parameter to SDL_MixAudio() has been increased in range | |
| 511 from (0-8) to (0-128) | |
| 512 | |
| 513 SDL now has a data source abstraction which can encompass a file, | |
| 514 an area of memory, or any custom object you can envision. It uses | |
| 515 these abstractions, SDL_RWops, in the endian read/write functions, | |
| 516 and the built-in WAV and BMP file loaders. This means you can load | |
| 517 WAV chunks from memory mapped files, compressed archives, network | |
| 518 pipes, or anything else that has a data read abstraction. | |
| 519 | |
| 520 There are three built-in data source abstractions: | |
| 521 SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem() | |
| 522 along with a generic data source allocation function: | |
| 523 SDL_AllocRW() | |
| 524 These data sources can be used like stdio file pointers with the | |
| 525 following convenience functions: | |
| 526 SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose() | |
| 527 These functions are defined in the new header file "SDL_rwops.h" | |
| 528 | |
| 529 The endian swapping functions have been turned into macros for speed | |
| 530 and SDL_CalculateEndian() has been removed. SDL_endian.h now defines | |
| 531 SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on | |
| 532 the endianness of the host system. | |
| 533 | |
| 534 The endian read/write functions now take an SDL_RWops pointer | |
| 535 instead of a stdio FILE pointer, to support the new data source | |
| 536 abstraction. | |
| 537 | |
| 538 The SDL_*LoadWAV() functions have been replaced with a single | |
| 539 SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's | |
| 540 first parameter, and a flag whether or not to automatically | |
| 541 free it as the second parameter. SDL_LoadWAV() is a macro for | |
| 542 backward compatibility and convenience: | |
| 543 SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...); | |
| 544 | |
| 545 The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced | |
| 546 with a single function that takes a SDL_RWops pointer as it's | |
| 547 first parameter, and a flag whether or not to automatically | |
| 548 free it as the second parameter. SDL_LoadBMP() and SDL_SaveBMP() | |
| 549 are macros for backward compatibility and convenience: | |
| 550 SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...); | |
| 551 SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...); | |
| 552 Note that these functions use SDL_RWseek() extensively, and should | |
| 553 not be used on pipes or other non-seekable data sources. | |
| 554 | |
| 555 0.9.10: | |
| 556 The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been | |
| 557 extended to support multiple types of display drivers, as well as | |
| 558 safe access to the X11 display when THREADED_EVENTS is enabled. | |
| 559 The new structures are documented in the SDL_syswm.h header file. | |
| 560 | |
| 561 Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard | |
| 562 should now work properly, as well as the "Windows" keys on US | |
| 563 keyboards. | |
| 564 | |
| 565 The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab | |
| 566 instead of trying to open each block device on the system. | |
| 567 The CD must be listed in /etc/fstab as using the iso9660 filesystem. | |
| 568 | |
| 569 On Linux, if you define THREADED_EVENTS at compile time, a separate | |
| 570 thread will be spawned to gather X events asynchronously from the | |
| 571 graphics updates. This hasn't been extensively tested, but it does | |
| 572 provide a means of handling keyboard and mouse input in a separate | |
| 573 thread from the graphics thread. (This is now enabled by default.) | |
| 574 | |
| 575 A special access function SDL_PeepEvents() allows you to manipulate | |
| 576 the event queue in a thread-safe manner, including peeking at events, | |
| 577 removing events of a specified type, and adding new events of arbitrary | |
| 578 type to the queue (use the new 'user' member of the SDL_Event type). | |
| 579 | |
| 580 If you use SDL_PeepEvents() to gather events, then the main graphics | |
| 581 thread needs to call SDL_PumpEvents() periodically to drive the event | |
| 582 loop and generate input events. This is not necessary if SDL has been | |
| 583 compiled with THREADED_EVENTS defined, but doesn't hurt. | |
| 584 | |
| 585 A new function SDL_ThreadID() returns the identifier associated with | |
| 586 the current thread. | |
| 587 | |
| 588 0.9.9: | |
| 589 The AUDIO_STEREO format flag has been replaced with a new 'channels' | |
| 590 member of the SDL_AudioSpec structure. The channels are 1 for mono | |
| 591 audio, and 2 for stereo audio. In the future more channels may be | |
| 592 supported for 3D surround sound. | |
| 593 | |
| 594 The SDL_MixAudio() function now takes an additional volume parameter, | |
| 595 which should be set to SDL_MIX_MAXVOLUME for compatibility with the | |
| 596 original function. | |
| 597 | |
| 598 The CD-ROM functions which take a 'cdrom' parameter can now be | |
| 599 passed NULL, and will act on the last successfully opened CD-ROM. | |
| 600 | |
| 601 0.9.8: | |
| 602 No changes, bugfixes only. | |
| 603 | |
| 604 0.9.7: | |
| 605 No changes, bugfixes only. | |
| 606 | |
| 607 0.9.6: | |
| 608 Added a fast rectangle fill function: SDL_FillRect() | |
| 609 | |
| 610 Addition of a useful function for getting info on the video hardware: | |
| 611 const SDL_VideoInfo *SDL_GetVideoInfo(void) | |
| 612 This function replaces SDL_GetDisplayFormat(). | |
| 613 | |
| 614 Initial support for double-buffering: | |
| 615 Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode() | |
| 616 Update the screen with a new function: SDL_Flip() | |
| 617 | |
| 618 SDL_AllocSurface() takes two new flags: | |
| 619 SDL_SRCCOLORKEY means that the surface will be used for colorkey blits | |
| 620 and if the hardware supports hardware acceleration of colorkey blits | |
| 621 between two surfaces in video memory, to place the surface in video | |
| 622 memory if possible, otherwise it will be placed in system memory. | |
| 623 SDL_SRCALPHA means that the surface will be used for alpha blits and | |
| 624 if the hardware supports hardware acceleration of alpha blits between | |
| 625 two surfaces in video memory, to place the surface in video memory | |
| 626 if possible, otherwise it will be placed in system memory. | |
| 627 SDL_HWSURFACE now means that the surface will be created with the | |
| 628 same format as the display surface, since having surfaces in video | |
| 629 memory is only useful for fast blitting to the screen, and you can't | |
| 630 blit surfaces with different surface formats in video memory. | |
| 631 | |
| 632 0.9.5: | |
| 633 You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume | |
| 634 that the icon consists of the entire image. | |
| 635 | |
| 636 SDL_LowerBlit() is back -- but don't use it on the display surface. | |
| 637 It is exactly the same as SDL_MiddleBlit(), but doesn't check for | |
| 638 thread safety. | |
| 639 | |
| 640 Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take | |
| 641 a FILE pointer instead of a file name. | |
| 642 | |
| 643 Added CD-ROM audio control API: | |
| 644 SDL_CDNumDrives() | |
| 645 SDL_CDName() | |
| 646 SDL_CDOpen() | |
| 647 SDL_CDStatus() | |
| 648 SDL_CDPlayTracks() | |
| 649 SDL_CDPlay() | |
| 650 SDL_CDPause() | |
| 651 SDL_CDResume() | |
| 652 SDL_CDStop() | |
| 653 SDL_CDEject() | |
| 654 SDL_CDClose() | |
| 655 | |
| 656 0.9.4: | |
| 657 No changes, bugfixes only. | |
| 658 | |
| 659 0.9.3: | |
| 660 Mouse motion event now includes relative motion information: | |
| 661 Sint16 event->motion.xrel, Sint16 event->motion.yrel | |
| 662 | |
| 663 X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT | |
| 664 (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile) | |
| 665 | |
| 666 0.9.2: | |
| 667 No changes, bugfixes only. | |
| 668 | |
| 669 0.9.1: | |
| 670 Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now | |
| 671 automatically mapped on blit. | |
| 672 | |
| 673 0.8.0: | |
| 674 SDL stable release |
