Subject: SDL/QNX6 new patch
Here in attachment my patch for the SDL/QNX6 again :) It contain non-crtitical/cosmetic fixes:
1. Fixed window centering at other than the first consoles.
2. Fixed window centering algorithm in case when window height or width are greater than the desktop resolution.
3. Fixed window positioning on other than the first consoles.
4. Fixed occasional input focus lost when switching to fullscreen.
5. Removed the Photon's default chroma color for the overlays, added RGB(12, 6, 12) color instead (very dark pink).
6. Added more checks to the YUV overlay code (fixed crashes during resolution mode switches).
7. Added support for Enter/Backspace keys in unicode mode (used by Maelstrom and by other games).
8. Fixed window restore/maximize function. It works, finally.

| 0 | 20 1.2.0: |
| 21 Added SDL_VIDEOEXPOSE event to signal that the screen needs to | |
| 22 be redrawn. This is currently only delivered to OpenGL windows | |
| 23 on X11, though it may be delivered in the future when the video | |
| 24 memory is lost under DirectX. | |
| 25 | |
| 26 1.1.8: | |
| 27 You can pass SDL_NOFRAME to SDL_VideoMode() to create a window | |
| 28 that has no title bar or frame decoration. Fullscreen video | |
| 29 modes automatically have this flag set. | |
| 30 | |
| 31 Added a function to query the clipping rectangle for a surface: | |
| 32 void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 33 | |
| 34 Added a function to query the current event filter: | |
| 35 SDL_EventFilter SDL_GetEventFilter(void) | |
| 36 | |
| 37 If you pass -1 to SDL_ShowCursor(), it won't change the current | |
| 38 cursor visibility state, but will still return it. | |
| 39 | |
| 40 SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning | |
| 41 you can nest them as deep as you want, as long as each lock call | |
| 42 has a matching unlock call. The surface remains locked until the | |
| 43 last matching unlock call. | |
| 44 | |
| 45 Note that you may not blit to or from a locked surface. | |
| 46 | |
| 47 1.1.7: | |
| 48 The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take | |
| 49 arrays of Uint16 values instead of Uint8 values. For the most part, | |
| 50 you can just take your old values and shift them up 8 bits to get | |
| 51 new correct values for your gamma ramps. | |
| 52 | |
| 53 You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface() | |
| 54 and SDL will try to RLE accelerate colorkey and alpha blits in the | |
| 55 resulting surface. | |
| 56 | |
| 57 1.1.6: | |
| 58 Added a function to return the thread ID of a specific thread: | |
| 59 Uint32 SDL_GetThreadID(SDL_Thread *thread) | |
| 60 If 'thread' is NULL, this function returns the id for this thread. | |
| 61 | |
| 62 1.1.5: | |
| 63 The YUV overlay structure has been changed to use an array of | |
| 64 pitches and pixels representing the planes of a YUV image, to | |
| 65 better enable hardware acceleration. The YV12 and IYUV formats | |
| 66 each have three planes, corresponding to the Y, U, and V portions | |
| 67 of the image, while packed pixel YUV formats just have one plane. | |
| 68 | |
| 69 For palettized mode (8bpp), the screen colormap is now split in | |
| 70 a physical and a logical palette. The physical palette determines | |
| 71 what colours the screen pixels will get when displayed, and the | |
| 72 logical palette controls the mapping from blits to/from the screen. | |
| 73 A new function, SDL_SetPalette() has been added to change | |
| 74 logical and physical palettes separately. SDL_SetColors() works | |
| 75 just as before, and is equivalent to calling SDL_SetPalette() with | |
| 76 a flag argument of (SDL_LOGPAL|SDL_PHYSPAL). | |
| 77 | |
| 78 SDL_BlitSurface() no longer modifies the source rectangle, only the | |
| 79 destination rectangle. The width/height members of the destination | |
| 80 rectangle are ignored, only the position is used. | |
| 81 | |
| 82 The old source clipping function SDL_SetClipping() has been replaced | |
| 83 with a more useful function to set the destination clipping rectangle: | |
| 84 SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 85 | |
| 86 Added a function to see what subsystems have been initialized: | |
| 87 Uint32 SDL_WasInit(Uint32 flags) | |
| 88 | |
| 89 The Big Alpha Flip: SDL now treats alpha as opacity like everybody | |
| 90 else, and not as transparency: | |
| 91 | |
| 92 A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255 | |
| 93 A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0 | |
| 94 Values between 0 and 255 vary from fully transparent to fully opaque. | |
| 95 | |
| 96 New functions: | |
| 97 SDL_DisplayFormatAlpha() | |
| 98 Returns a surface converted to a format with alpha-channel | |
| 99 that can be blit efficiently to the screen. (In other words, | |
| 100 like SDL_DisplayFormat() but the resulting surface has | |
| 101 an alpha channel.) This is useful for surfaces with alpha. | |
| 102 SDL_MapRGBA() | |
| 103 Works as SDL_MapRGB() but takes an additional alpha parameter. | |
| 104 SDL_GetRGBA() | |
| 105 Works as SDL_GetRGB() but also returns the alpha value | |
| 106 (SDL_ALPHA_OPAQUE for formats without an alpha channel) | |
| 107 | |
| 108 Both SDL_GetRGB() and SDL_GetRGBA() now always return values in | |
| 109 the [0..255] interval. Previously, SDL_GetRGB() would return | |
| 110 (0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format. | |
| 111 (N.B.: This is broken for bit fields < 3 bits.) | |
| 112 | |
| 113 SDL_MapRGB() returns pixels in which the alpha channel is set opaque. | |
| 114 | |
| 115 SDL_SetAlpha() can now be used for both setting the per-surface | |
| 116 alpha, using the new way of thinking of alpha, and also to enable | |
| 117 and disable per-pixel alpha blending for surfaces with an alpha | |
| 118 channel: | |
| 119 To disable alpha blending: | |
| 120 SDL_SetAlpha(surface, 0, 0); | |
| 121 To re-enable alpha blending: | |
| 122 SDL_SetAlpha(surface, SDL_SRCALPHA, 0); | |
| 123 Surfaces with an alpha channel have blending enabled by default. | |
| 124 | |
| 125 SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests | |
| 126 RLE acceleration of blits, just as like with SDL_SetColorKey(). | |
| 127 This flag can be set for both surfaces with an alpha channel | |
| 128 and surfaces with an alpha value set by SDL_SetAlpha(). | |
| 129 As always, RLE surfaces must be locked before pixel access is | |
| 130 allowed, and unlocked before any other SDL operations are done | |
| 131 on it. | |
| 132 | |
| 133 The blit semantics for surfaces with and without alpha and colorkey | |
| 134 have now been defined: | |
| 135 | |
| 136 RGBA->RGB: | |
| 137 SDL_SRCALPHA set: | |
| 138 alpha-blend (using alpha-channel). | |
| 139 SDL_SRCCOLORKEY ignored. | |
| 140 SDL_SRCALPHA not set: | |
| 141 copy RGB. | |
| 142 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 143 RGB values of the source colour key, ignoring alpha in the | |
| 144 comparison. | |
| 145 | |
| 146 RGB->RGBA: | |
| 147 SDL_SRCALPHA set: | |
| 148 alpha-blend (using the source per-surface alpha value); | |
| 149 set destination alpha to opaque. | |
| 150 SDL_SRCALPHA not set: | |
| 151 copy RGB, set destination alpha to opaque. | |
| 152 both: | |
| 153 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 154 source colour key. | |
| 155 | |
| 156 RGBA->RGBA: | |
| 157 SDL_SRCALPHA set: | |
| 158 alpha-blend (using the source alpha channel) the RGB values; | |
| 159 leave destination alpha untouched. [Note: is this correct?] | |
| 160 SDL_SRCCOLORKEY ignored. | |
| 161 SDL_SRCALPHA not set: | |
| 162 copy all of RGBA to the destination. | |
| 163 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 164 RGB values of the source colour key, ignoring alpha in the | |
| 165 comparison. | |
| 166 | |
| 167 RGB->RGB: | |
| 168 SDL_SRCALPHA set: | |
| 169 alpha-blend (using the source per-surface alpha value). | |
| 170 SDL_SRCALPHA not set: | |
| 171 copy RGB. | |
| 172 both: | |
| 173 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 174 source colour key. | |
| 175 | |
| 176 As a special case, blits from surfaces with per-surface alpha | |
| 177 value of 128 (50% transparency) are optimised and much faster | |
| 178 than other alpha values. This does not apply to surfaces with | |
| 179 alpha channels (per-pixel alpha). | |
| 180 | |
| 181 New functions for manipulating the gamma of the display have | |
| 182 been added: | |
| 183 int SDL_SetGamma(float red, float green, float blue); | |
| 184 int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 185 int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 186 Gamma ramps are tables with 256 entries which map the screen color | |
| 187 components into actually displayed colors. For an example of | |
| 188 implementing gamma correction and gamma fades, see test/testgamma.c | |
| 189 Gamma control is not supported on all hardware. | |
| 190 | |
| 191 1.1.4: | |
| 192 The size of the SDL_CDtrack structure changed from 8 to 12 bytes | |
| 193 as the size of the length member was extended to 32 bits. | |
| 194 | |
| 195 You can now use SDL for 2D blitting with a GL mode by passing the | |
| 196 SDL_OPENGLBLIT flag to SDL_SetVideoMode(). You can specify 16 or | |
| 197 32 bpp, and the data in the framebuffer is put into the GL scene | |
| 198 when you call SDL_UpdateRects(), and the scene will be visible | |
| 199 when you call SDL_GL_SwapBuffers(). | |
| 200 | |
| 201 Run the "testgl" test program with the -logo command line option | |
| 202 to see an example of this blending of 2D and 3D in SDL. | |
| 203 | |
| 204 1.1.3: | |
| 205 Added SDL_FreeRW() to the API, to complement SDL_AllocRW() | |
| 206 | |
| 207 Added resizable window support - just add SDL_RESIZABLE to the | |
| 208 SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events. | |
| 209 See SDL_events.h for details on the new SDL_ResizeEvent structure. | |
| 210 | |
| 211 Added condition variable support, based on mutexes and semaphores. | |
| 212 SDL_CreateCond() | |
| 213 SDL_DestroyCond() | |
| 214 SDL_CondSignal() | |
| 215 SDL_CondBroadcast() | |
| 216 SDL_CondWait() | |
| 217 SDL_CondTimedWait() | |
| 218 The new function prototypes are in SDL_mutex.h | |
| 219 | |
| 220 Added counting semaphore support, based on the mutex primitive. | |
| 221 SDL_CreateSemaphore() | |
| 222 SDL_DestroySemaphore() | |
| 223 SDL_SemWait() | |
| 224 SDL_SemTryWait() | |
| 225 SDL_SemWaitTimeout() | |
| 226 SDL_SemPost() | |
| 227 SDL_SemValue() | |
| 228 The new function prototypes are in SDL_mutex.h | |
| 229 | |
| 230 Added support for asynchronous blitting. To take advantage of this, | |
| 231 you must set the SDL_ASYNCBLIT flag when setting the video mode and | |
| 232 creating surfaces that you want accelerated in this way. You must | |
| 233 lock surfaces that have this flag set, and the lock will block until | |
| 234 any queued blits have completed. | |
| 235 | |
| 236 Added YUV video overlay support. | |
| 237 The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU. | |
| 238 This function creates an overlay surface: | |
| 239 SDL_CreateYUVOverlay() | |
| 240 You must lock and unlock the overlay to get access to the data: | |
| 241 SDL_LockYUVOverlay() SDL_UnlockYUVOverlay() | |
| 242 You can then display the overlay: | |
| 243 SDL_DisplayYUVOverlay() | |
| 244 You must free the overlay when you are done using it: | |
| 245 SDL_FreeYUVOverlay() | |
| 246 See SDL_video.h for the full function prototypes. | |
| 247 | |
| 248 The joystick hat position constants have been changed: | |
| 249 Old constant New constant | |
| 250 ------------ ------------ | |
| 251 0 SDL_HAT_CENTERED | |
| 252 1 SDL_HAT_UP | |
| 253 2 SDL_HAT_RIGHTUP | |
| 254 3 SDL_HAT_RIGHT | |
| 255 4 SDL_HAT_RIGHTDOWN | |
| 256 5 SDL_HAT_DOWN | |
| 257 6 SDL_HAT_LEFTDOWN | |
| 258 7 SDL_HAT_LEFT | |
| 259 8 SDL_HAT_LEFTUP | |
| 260 The new constants are bitmasks, so you can check for the | |
| 261 individual axes like this: | |
| 262 if ( hat_position & SDL_HAT_UP ) { | |
| 263 } | |
| 264 and you'll catch left-up, up, and right-up. | |
| 265 | |
| 266 1.1.2: | |
| 267 Added multiple timer support: | |
| 268 SDL_AddTimer() and SDL_RemoveTimer() | |
| 269 | |
| 270 SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL. | |
| 271 | |
| 272 1.1.0: | |
| 273 Added initial OpenGL support. | |
| 274 First set GL attributes (such as RGB depth, alpha depth, etc.) | |
| 275 SDL_GL_SetAttribute() | |
| 276 Then call SDL_SetVideoMode() with the SDL_OPENGL flag. | |
| 277 Perform all of your normal GL drawing. | |
| 278 Finally swap the buffers with the new SDL function: | |
| 279 SDL_GL_SwapBuffers() | |
| 280 See the new 'testgl' test program for an example of using GL with SDL. | |
| 281 | |
| 282 You can load GL extension functions by using the function: | |
| 283 SDL_GL_LoadProcAddress() | |
| 284 | |
| 285 Added functions to initialize and cleanup specific SDL subsystems: | |
| 286 SDL_InitSubSystem() and SDL_QuitSubSystem() | |
| 287 | |
| 288 Added user-defined event type: | |
| 289 typedef struct { | |
| 290 Uint8 type; | |
| 291 int code; | |
| 292 void *data1; | |
| 293 void *data2; | |
| 294 } SDL_UserEvent; | |
| 295 This structure is in the "user" member of an SDL_Event. | |
| 296 | |
| 297 Added a function to push events into the event queue: | |
| 298 SDL_PushEvent() | |
| 299 | |
| 300 Example of using the new SDL user-defined events: | |
| 301 { | |
| 302 SDL_Event event; | |
| 303 | |
| 304 event.type = SDL_USEREVENT; | |
| 305 event.user.code = my_event_code; | |
| 306 event.user.data1 = significant_data; | |
| 307 event.user.data2 = 0; | |
| 308 SDL_PushEvent(&event); | |
| 309 } | |
| 310 | |
| 311 Added a function to get mouse deltas since last query: | |
| 312 SDL_GetRelativeMouseState() | |
| 313 | |
| 314 Added a boolean datatype to SDL_types.h: | |
| 315 SDL_bool = { SDL_TRUE, SDL_FALSE } | |
| 316 | |
| 317 Added a function to get the current audio status: | |
| 318 SDL_GetAudioState(); | |
| 319 It returns one of: | |
| 320 SDL_AUDIO_STOPPED, | |
| 321 SDL_AUDIO_PLAYING, | |
| 322 SDL_AUDIO_PAUSED | |
| 323 | |
| 324 Added an AAlib driver (ASCII Art) - by Stephane Peter. | |
| 325 | |
| 326 1.0.6: | |
| 327 The input grab state is reset after each call to SDL_SetVideoMode(). | |
| 328 The input is grabbed by default in fullscreen mode, and ungrabbed in | |
| 329 windowed mode. If you want to set input grab to a particular value, | |
| 330 you should set it after each call to SDL_SetVideoMode(). | |
| 331 | |
| 332 1.0.5: | |
| 333 Exposed SDL_AudioInit(), SDL_VideoInit() | |
| 334 Added SDL_AudioDriverName() and SDL_VideoDriverName() | |
| 335 | |
| 336 Added new window manager function: | |
| 337 SDL_WM_ToggleFullScreen() | |
| 338 This is currently implemented only on Linux | |
| 339 | |
| 340 The ALT-ENTER code has been removed - it's not appropriate for a | |
| 341 lib to bind keys when they aren't even emergency escape sequences. | |
| 342 | |
| 343 ALT-ENTER functionality can be implemented with the following code: | |
| 344 | |
| 345 int Handle_AltEnter(const SDL_Event *event) | |
| 346 { | |
| 347 if ( event->type == SDL_KEYDOWN ) { | |
| 348 if ( (event->key.keysym.sym == SDLK_RETURN) && | |
| 349 (event->key.keysym.mod & KMOD_ALT) ) { | |
| 350 SDL_WM_ToggleFullScreen(SDL_GetVideoSurface()); | |
| 351 return(0); | |
| 352 } | |
| 353 } | |
| 354 return(1); | |
| 355 } | |
| 356 SDL_SetEventFilter(Handle_AltEnter); | |
| 357 | |
| 358 1.0.3: | |
| 359 Under X11, if you grab the input and hide the mouse cursor, | |
| 360 the mouse will go into a "relative motion" mode where you | |
| 361 will always get relative motion events no matter how far in | |
| 362 each direction you move the mouse - relative motion is not | |
| 363 bounded by the edges of the window (though the absolute values | |
| 364 of the mouse positions are clamped by the size of the window). | |
| 365 The SVGAlib, framebuffer console, and DirectInput drivers all | |
| 366 have this behavior naturally, and the GDI and BWindow drivers | |
| 367 never go into "relative motion" mode. | |
| 368 | |
| 369 1.0.2: | |
| 370 Added a function to enable keyboard repeat: | |
| 371 SDL_EnableKeyRepeat() | |
| 372 | |
| 373 Added a function to grab the mouse and keyboard input | |
| 374 SDL_WM_GrabInput() | |
| 375 | |
| 376 Added a function to iconify the window. | |
| 377 SDL_WM_IconifyWindow() | |
| 378 If this function succeeds, the application will receive an event | |
| 379 signaling SDL_APPACTIVE event | |
| 380 | |
| 381 1.0.1: | |
| 382 Added constants to SDL_audio.h for 16-bit native byte ordering: | |
| 383 AUDIO_U16SYS, AUDIO_S16SYS | |
| 384 | |
| 385 1.0.0: | |
| 386 New public release | |
| 387 | |
| 388 Version 0.11: | |
| 389 | |
| 390 0.11.5: | |
| 391 A new function SDL_GetVideoSurface() has been added, and returns | |
| 392 a pointer to the current display surface. | |
| 393 | |
| 394 SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and | |
| 395 a new function SDL_CreateRGBSurfaceFrom() has been added to allow | |
| 396 creating an SDL surface from an existing pixel data buffer. | |
| 397 | |
| 398 Added SDL_GetRGB() to the headers and documentation. | |
| 399 | |
| 400 0.11.4: | |
| 401 SDL_SetLibraryPath() is no longer meaningful, and has been removed. | |
| 402 | |
| 403 0.11.3: | |
| 404 A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from | |
| 405 installing fatal signal handlers on operating systems that support | |
| 406 them. | |
| 407 | |
| 408 Version 0.9: | |
| 409 | |
| 410 0.9.15: | |
| 411 SDL_CreateColorCursor() has been removed. Color cursors should | |
| 412 be implemented as sprites, blitted by the application when the | |
| 413 cursor moves. To get smooth color cursor updates when the app | |
| 414 is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init(). This | |
| 415 allows you to handle the mouse motion in another thread from an | |
| 416 event filter function, but is currently only supported by Linux | |
| 417 and BeOS. Note that you'll have to protect the display surface | |
| 418 from multi-threaded access by using mutexes if you do this. | |
| 419 | |
| 420 Thread-safe surface support has been removed from SDL. | |
| 421 This makes blitting somewhat faster, by removing SDL_MiddleBlit(). | |
| 422 Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead. | |
| 423 You can make your surfaces thread-safe by allocating your own | |
| 424 mutex and making lock/unlock calls around accesses to your surface. | |
| 425 | |
| 426 0.9.14: | |
| 427 SDL_GetMouseState() now takes pointers to int rather than Uint16. | |
| 428 | |
| 429 If you set the SDL_WINDOWID environment variable under UNIX X11, | |
| 430 SDL will use that as the main window instead of creating it's own. | |
| 431 This is an unsupported extension to SDL, and not portable at all. | |
| 432 | |
| 433 0.9.13: | |
| 434 Added a function SDL_SetLibraryPath() which can be used to specify | |
| 435 the directory containing the SDL dynamic libraries. This is useful | |
| 436 for commercial applications which ship with particular versions | |
| 437 of the libraries, and for security on multi-user systems. | |
| 438 If this function is not used, the default system directories are | |
| 439 searched using the native dynamic object loading mechanism. | |
| 440 | |
| 441 In order to support C linkage under Visual C++, you must declare | |
| 442 main() without any return type: | |
| 443 main(int argc, char *argv[]) { | |
| 444 /* Do the program... */ | |
| 445 return(0); | |
| 446 } | |
| 447 C++ programs should also return a value if compiled under VC++. | |
| 448 | |
| 449 The blit_endian member of the SDL_VideoInfo struct has been removed. | |
| 450 | |
| 451 SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there | |
| 452 is now no longer any function to translate a keysym to a character. | |
| 453 | |
| 454 The SDL_keysym structure has been extended with a 'scancode' and | |
| 455 'unicode' member. The 'scancode' is a hardware specific scancode | |
| 456 for the key that was pressed, and may be 0. The 'unicode' member | |
| 457 is a 16-bit UNICODE translation of the key that was pressed along | |
| 458 with any modifiers or compose keys that have been pressed. | |
| 459 If no UNICODE translation exists for the key, 'unicode' will be 0. | |
| 460 | |
| 461 Added a function SDL_EnableUNICODE() to enable/disable UNICODE | |
| 462 translation of character keypresses. Translation defaults off. | |
| 463 | |
| 464 To convert existing code to use the new API, change code which | |
| 465 uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(), | |
| 466 and change code which uses it to get the ASCII value of a sym to | |
| 467 use the 'unicode' member of the event keysym. | |
| 468 | |
| 469 0.9.12: | |
| 470 There is partial support for 64-bit datatypes. I don't recommend | |
| 471 you use this if you have a choice, because 64-bit datatypes are not | |
| 472 supported on many platforms. On platforms for which it is supported, | |
| 473 the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and | |
| 474 you can use the Uint64 and Sint64 datatypes. | |
| 475 | |
| 476 Added functions to SDL_endian.h to support 64-bit datatypes: | |
| 477 SDL_SwapLE64(), SDL_SwapBE64(), | |
| 478 SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64() | |
| 479 | |
| 480 A new member "len_ratio" has been added to the SDL_AudioCVT structure, | |
| 481 and allows you to determine either the original buffer length or the | |
| 482 converted buffer length, given the other. | |
| 483 | |
| 484 A new function SDL_FreeWAV() has been added to the API to free data | |
| 485 allocated by SDL_LoadWAV_RW(). This is necessary under Win32 since | |
| 486 the gcc compiled DLL uses a different heap than VC++ compiled apps. | |
| 487 | |
| 488 SDL now has initial support for international keyboards using the | |
| 489 Latin character set. | |
| 490 If a particular mapping is desired, you can set the DEFAULT_KEYBOARD | |
| 491 compile-time variable, or you can set the environment variable | |
| 492 "SDL_KEYBOARD" to a string identifying the keyboard mapping you desire. | |
| 493 The valid values for these variables can be found in SDL_keyboard.c | |
| 494 | |
| 495 Full support for German and French keyboards under X11 is implemented. | |
| 496 | |
| 497 0.9.11: | |
| 498 The THREADED_EVENTS compile-time define has been replaced with the | |
| 499 SDL_INIT_EVENTTHREAD flag. If this flag is passed to SDL_Init(), | |
| 500 SDL will create a separate thread to perform input event handling. | |
| 501 If this flag is passed to SDL_Init(), and the OS doesn't support | |
| 502 event handling in a separate thread, SDL_Init() will fail. | |
| 503 Be sure to add calls to SDL_Delay() in your main thread to allow | |
| 504 the OS to schedule your event thread, or it may starve, leading | |
| 505 to slow event delivery and/or dropped events. | |
| 506 Currently MacOS and Win32 do not support this flag, while BeOS | |
| 507 and Linux do support it. I recommend that your application only | |
| 508 use this flag if absolutely necessary. | |
| 509 | |
| 510 The SDL thread function passed to SDL_CreateThread() now returns a | |
| 511 status. This status can be retrieved by passing a non-NULL pointer | |
| 512 as the 'status' argument to SDL_WaitThread(). | |
| 513 | |
| 514 The volume parameter to SDL_MixAudio() has been increased in range | |
| 515 from (0-8) to (0-128) | |
| 516 | |
| 517 SDL now has a data source abstraction which can encompass a file, | |
| 518 an area of memory, or any custom object you can envision. It uses | |
| 519 these abstractions, SDL_RWops, in the endian read/write functions, | |
| 520 and the built-in WAV and BMP file loaders. This means you can load | |
| 521 WAV chunks from memory mapped files, compressed archives, network | |
| 522 pipes, or anything else that has a data read abstraction. | |
| 523 | |
| 524 There are three built-in data source abstractions: | |
| 525 SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem() | |
| 526 along with a generic data source allocation function: | |
| 527 SDL_AllocRW() | |
| 528 These data sources can be used like stdio file pointers with the | |
| 529 following convenience functions: | |
| 530 SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose() | |
| 531 These functions are defined in the new header file "SDL_rwops.h" | |
| 532 | |
| 533 The endian swapping functions have been turned into macros for speed | |
| 534 and SDL_CalculateEndian() has been removed. SDL_endian.h now defines | |
| 535 SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on | |
| 536 the endianness of the host system. | |
| 537 | |
| 538 The endian read/write functions now take an SDL_RWops pointer | |
| 539 instead of a stdio FILE pointer, to support the new data source | |
| 540 abstraction. | |
| 541 | |
| 542 The SDL_*LoadWAV() functions have been replaced with a single | |
| 543 SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's | |
| 544 first parameter, and a flag whether or not to automatically | |
| 545 free it as the second parameter. SDL_LoadWAV() is a macro for | |
| 546 backward compatibility and convenience: | |
| 547 SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...); | |
| 548 | |
| 549 The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced | |
| 550 with a single function that takes a SDL_RWops pointer as it's | |
| 551 first parameter, and a flag whether or not to automatically | |
| 552 free it as the second parameter. SDL_LoadBMP() and SDL_SaveBMP() | |
| 553 are macros for backward compatibility and convenience: | |
| 554 SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...); | |
| 555 SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...); | |
| 556 Note that these functions use SDL_RWseek() extensively, and should | |
| 557 not be used on pipes or other non-seekable data sources. | |
| 558 | |
| 559 0.9.10: | |
| 560 The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been | |
| 561 extended to support multiple types of display drivers, as well as | |
| 562 safe access to the X11 display when THREADED_EVENTS is enabled. | |
| 563 The new structures are documented in the SDL_syswm.h header file. | |
| 564 | |
| 565 Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard | |
| 566 should now work properly, as well as the "Windows" keys on US | |
| 567 keyboards. | |
| 568 | |
| 569 The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab | |
| 570 instead of trying to open each block device on the system. | |
| 571 The CD must be listed in /etc/fstab as using the iso9660 filesystem. | |
| 572 | |
| 573 On Linux, if you define THREADED_EVENTS at compile time, a separate | |
| 574 thread will be spawned to gather X events asynchronously from the | |
| 575 graphics updates. This hasn't been extensively tested, but it does | |
| 576 provide a means of handling keyboard and mouse input in a separate | |
| 577 thread from the graphics thread. (This is now enabled by default.) | |
| 578 | |
| 579 A special access function SDL_PeepEvents() allows you to manipulate | |
| 580 the event queue in a thread-safe manner, including peeking at events, | |
| 581 removing events of a specified type, and adding new events of arbitrary | |
| 582 type to the queue (use the new 'user' member of the SDL_Event type). | |
| 583 | |
| 584 If you use SDL_PeepEvents() to gather events, then the main graphics | |
| 585 thread needs to call SDL_PumpEvents() periodically to drive the event | |
| 586 loop and generate input events. This is not necessary if SDL has been | |
| 587 compiled with THREADED_EVENTS defined, but doesn't hurt. | |
| 588 | |
| 589 A new function SDL_ThreadID() returns the identifier associated with | |
| 590 the current thread. | |
| 591 | |
| 592 0.9.9: | |
| 593 The AUDIO_STEREO format flag has been replaced with a new 'channels' | |
| 594 member of the SDL_AudioSpec structure. The channels are 1 for mono | |
| 595 audio, and 2 for stereo audio. In the future more channels may be | |
| 596 supported for 3D surround sound. | |
| 597 | |
| 598 The SDL_MixAudio() function now takes an additional volume parameter, | |
| 599 which should be set to SDL_MIX_MAXVOLUME for compatibility with the | |
| 600 original function. | |
| 601 | |
| 602 The CD-ROM functions which take a 'cdrom' parameter can now be | |
| 603 passed NULL, and will act on the last successfully opened CD-ROM. | |
| 604 | |
| 605 0.9.8: | |
| 606 No changes, bugfixes only. | |
| 607 | |
| 608 0.9.7: | |
| 609 No changes, bugfixes only. | |
| 610 | |
| 611 0.9.6: | |
| 612 Added a fast rectangle fill function: SDL_FillRect() | |
| 613 | |
| 614 Addition of a useful function for getting info on the video hardware: | |
| 615 const SDL_VideoInfo *SDL_GetVideoInfo(void) | |
| 616 This function replaces SDL_GetDisplayFormat(). | |
| 617 | |
| 618 Initial support for double-buffering: | |
| 619 Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode() | |
| 620 Update the screen with a new function: SDL_Flip() | |
| 621 | |
| 622 SDL_AllocSurface() takes two new flags: | |
| 623 SDL_SRCCOLORKEY means that the surface will be used for colorkey blits | |
| 624 and if the hardware supports hardware acceleration of colorkey blits | |
| 625 between two surfaces in video memory, to place the surface in video | |
| 626 memory if possible, otherwise it will be placed in system memory. | |
| 627 SDL_SRCALPHA means that the surface will be used for alpha blits and | |
| 628 if the hardware supports hardware acceleration of alpha blits between | |
| 629 two surfaces in video memory, to place the surface in video memory | |
| 630 if possible, otherwise it will be placed in system memory. | |
| 631 SDL_HWSURFACE now means that the surface will be created with the | |
| 632 same format as the display surface, since having surfaces in video | |
| 633 memory is only useful for fast blitting to the screen, and you can't | |
| 634 blit surfaces with different surface formats in video memory. | |
| 635 | |
| 636 0.9.5: | |
| 637 You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume | |
| 638 that the icon consists of the entire image. | |
| 639 | |
| 640 SDL_LowerBlit() is back -- but don't use it on the display surface. | |
| 641 It is exactly the same as SDL_MiddleBlit(), but doesn't check for | |
| 642 thread safety. | |
| 643 | |
| 644 Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take | |
| 645 a FILE pointer instead of a file name. | |
| 646 | |
| 647 Added CD-ROM audio control API: | |
| 648 SDL_CDNumDrives() | |
| 649 SDL_CDName() | |
| 650 SDL_CDOpen() | |
| 651 SDL_CDStatus() | |
| 652 SDL_CDPlayTracks() | |
| 653 SDL_CDPlay() | |
| 654 SDL_CDPause() | |
| 655 SDL_CDResume() | |
| 656 SDL_CDStop() | |
| 657 SDL_CDEject() | |
| 658 SDL_CDClose() | |
| 659 | |
| 660 0.9.4: | |
| 661 No changes, bugfixes only. | |
| 662 | |
| 663 0.9.3: | |
| 664 Mouse motion event now includes relative motion information: | |
| 665 Sint16 event->motion.xrel, Sint16 event->motion.yrel | |
| 666 | |
| 667 X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT | |
| 668 (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile) | |
| 669 | |
| 670 0.9.2: | |
| 671 No changes, bugfixes only. | |
| 672 | |
| 673 0.9.1: | |
| 674 Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now | |
| 675 automatically mapped on blit. | |
| 676 | |
| 677 0.8.0: | |
| 678 SDL stable release |
