* event-stream.c (Faccept_process_output):
Restore the current buffer even on non-local exit in this
function, none of the code that uses #'accept-process-output is
actually prepared to handle the current buffer changing.

| 32 | |
| 442 | 33 ;; Dialog boxes are non-modal at the C level, but made modal at the |
| 34 ;; Lisp level via hacks in functions such as yes-or-no-p-dialog-box | |
| 35 ;; below. Perhaps there should be truly modal dialog boxes | |
| 36 ;; implemented at the C level for safety. All code using dialog boxes | |
| 37 ;; should be careful to assume that the environment, for example the | |
| 38 ;; current buffer, might be completely different after returning from | |
| 39 ;; yes-or-no-p-dialog-box, but such code is difficult to write and test. | |

124 spec &allow-other-keys) |
| 442 | 125 "Pop up a dialog box. |
| 126 TYPE is a symbol, the type of dialog box. Remaining arguments are | |
| 127 keyword-value pairs, specifying the particular characteristics of the | |
| 128 dialog box. The allowed keywords are particular to each type, but | |
| 129 some standard keywords are common to many types: | |
| 130 | |
| 131 :title | |
| 132 The title of the dialog box's window. | |
| 133 | |
| 134 :modal | |
| 135 If true, indicates that XEmacs will wait until the user is \"done\" | |
| 136 with the dialog box (usually, this means that a response has been | |
| 137 given). Typically, the response is returned. NOTE: Some dialog | |
| 138 boxes are always modal. If the dialog box is modal, `make-dialog-box' | |
| 139 returns immediately. The return value will be either nil or a | |
| 140 dialog box handle of some sort, e.g. a frame for type `general'. | |
| 141 | |
| 142 --------------------------------------------------------------------------- | |
| 143 | |
| 144 Recognized types are | |
| 145 | |
| 146 general | |
| 147 A dialog box consisting of an XEmacs glyph, typically a `layout' | |
| 148 widget specifying a dialog box arrangement. This is the most | |
| 149 general and powerful dialog box type, but requires more work than | |
| 150 the other types below. | |
| 151 | |
| 152 question | |
| 153 A simple dialog box that displays a question and contains one or | |
| 154 more user-defined buttons to specify possible responses. (This is | |
| 155 compatible with the old built-in dialog boxes formerly specified | |
| 156 using `popup-dialog-box'.) | |
| 157 | |
| 158 file | |
| 159 A file dialog box, of the type typically used in the window system | |
| 160 XEmacs is running on. | |
| 161 | |
| 162 color | |
| 163 A color picker. | |
| 164 | |
| 165 find | |
| 166 A find dialog box. | |
| 167 | |
| 168 font | |
| 169 A font chooser. | |
| 170 | |
| 171 print | |
| 172 A dialog box used when printing (e.g. number of pages, printer). | |
| 173 | |
| 174 page-setup | |
| 175 A dialog box for setting page options (e.g. margins) for printing. | |
| 176 | |
| 177 replace | |
| 178 A find/replace dialog box. | |
| 179 | |
| 180 mswindows-message | |
| 181 An MS Windows-specific standard dialog box type similar to `question'. | |
| 182 | |
| 183 --------------------------------------------------------------------------- | |
| 184 | |
| 185 For type `general': | |
| 186 | |
| 187 This type creates a frame and puts the specified widget layout in it. | |
| 188 \(Currently this is done by eliminating all areas but the gutter and placing | |
| 189 the layout there; but this is an implementation detail and may change.) | |
| 190 | |
| 191 The keywords allowed for `general' are | |
| 192 | |
| 193 :spec | |
| 194 The widget spec -- anything that can be passed to `make-glyph'. | |
| 195 :title | |
| 196 The title of the frame. | |
| 197 :parent | |
| 198 The frame is made a child of this frame (defaults to the selected frame). | |
| 199 :properties | |
| 200 Additional properties of the frame, as well as `dialog-frame-plist'. | |
| 863 | 201 :autosize |
| 202 If t the frame is sized to exactly fit the widgets given by :spec. | |
| 442 | 203 |
| 204 --------------------------------------------------------------------------- | |
| 205 | |
| 206 For type `question': | |
| 207 | |
| 208 The keywords allowed are | |
| 209 | |
| 210 :modal | |
| 211 t or nil. When t, the dialog box callback should exit the dialog box | |
| 212 using the functions `dialog-box-finish' or `dialog-box-cancel'. | |
| 213 :title | |
| 214 The title of the frame. | |
| 215 :question | |
| 216 A string, the question. | |
| 217 :buttons | |
| 218 A list, describing the buttons below the question. Each of these is a | |
| 219 vector, the syntax of which is essentially the same as that of popup menu | |
| 220 items. They may have any of the following forms: | |
| 221 | |
| 222 [ \"name\" callback <active-p> ] | |
| 223 [ \"name\" callback <active-p> \"suffix\" ] | |
| 224 [ \"name\" callback :<keyword> <value> :<keyword> <value> ... ] | |
| 225 | |
| 226 The name is the string to display on the button; it is filtered through the | |
| 227 resource database, so it is possible for resources to override what string | |
| 228 is actually displayed. | |
| 229 | |
| 230 Accelerators can be indicated in the string by putting the sequence | |
| 231 \"%_\" before the character corresponding to the key that will invoke | |
| 232 the button. Uppercase and lowercase accelerators are equivalent. The | |
| 233 sequence \"%%\" is also special, and is translated into a single %. | |
| 234 | |
| 235 If the `callback' of a button is a symbol, then it must name a command. | |
| 236 It will be invoked with `call-interactively'. If it is a list, then it is | |
| 237 evaluated with `eval'. | |
| 238 | |
| 239 One (and only one) of the buttons may be `nil'. This marker means that all | |
| 240 following buttons should be flushright instead of flushleft. | |
| 241 | |
| 242 Though the keyword/value syntax is supported for dialog boxes just as in | |
| 243 popup menus, the only keyword which is both meaningful and fully implemented | |
| 244 for dialog box buttons is `:active'. | |
| 245 | |
| 246 --------------------------------------------------------------------------- | |
| 247 | |
| 248 For type `file': | |
| 249 | |
| 250 The keywords allowed are | |
| 251 | |
| 252 :initial-filename | |
| 253 The initial filename to be placed in the dialog box (defaults to nothing). | |
| 254 :initial-directory | |
| 255 The initial directory to be selected in the dialog box (defaults to the | |
| 256 current buffer's `default-directory). | |
| 257 :filter-list | |
| 258 A list of (filter-desc filter ...) | |
| 259 :title | |
| 260 The title of the dialog box (defaults to \"Open\"). | |
| 261 :allow-multi-select t or nil | |
| 262 :create-prompt-on-nonexistent t or nil | |
| 263 :overwrite-prompt t or nil | |
| 264 :file-must-exist t or nil | |
| 265 :no-network-button t or nil | |
| 266 :no-read-only-return t or nil | |
| 267 | |
| 268 --------------------------------------------------------------------------- | |
| 269 | |
| 673 | 270 For type `directory': |
| 271 | |
| 272 The keywords allowed are | |
| 273 | |
| 274 :initial-directory | |
| 275 The initial directory to be selected in the dialog box (defaults to the | |
| 276 current buffer's `default-directory). | |
| 277 :title | |
| 278 The title of the dialog box (defaults to \"Open\"). | |
| 279 | |
| 280 --------------------------------------------------------------------------- | |
| 281 | |
| 442 | 282 For type `print': |
| 283 | |
| 284 This invokes the Windows standard Print dialog. | |
| 285 This dialog is usually invoked when the user selects the Print command. | |
| 286 After the user presses OK, the program should start actual printout. | |
| 287 | |
| 288 The keywords allowed are | |
| 289 | |
| 290 :device | |
| 291 An 'msprinter device. | |
| 292 :print-settings | |
| 293 A printer settings object. | |
| 510 | 294 :allow-selection |
| 295 t or nil -- whether the \"Selection\" button is enabled (defaults to nil). | |
| 296 :allow-pages | |
| 297 t or nil -- whether the \"Pages\" button and associated edit controls | |
| 298 are enabled (defaults to t). | |
| 299 :selected-page-button | |
| 300 `all', `selection', or `pages' -- which page button is initially | |
| 301 selected. | |
| 442 | 302 |
| 510 | 303 Exactly one of :device and :print-settings must be given. |
| 442 | 304 |
| 305 The function brings up the Print dialog, where the user can | |
| 506 | 306 select a different printer and/or change printer options. Connection |
| 442 | 307 name can change as a result of selecting a different printer device. If |
| 506 | 308 a device is specified, then changes are stored into the settings object |
| 442 | 309 currently selected into that printer. If a settings object is supplied, |
| 629 | 310 then changes are recorded into it, and, it is selected into a |
| 442 | 311 printer, then changes are propagated to that printer |
| 312 too. | |
| 313 | |
| 314 Return value is nil if the user has canceled the dialog. Otherwise, it | |
| 315 is a new plist, with the following properties: | |
| 510 | 316 name Printer device name, even if unchanged by the user. |
| 317 from-page First page to print, 1-based. Returned if | |
| 318 `selected-page-button' is `pages'. | |
| 319 user, then this value is not included in the plist. | |
| 320 to-page Last page to print, inclusive, 1-based. Returned if | |
| 321 `selected-page-button' is `pages'. | |
| 322 copies Number of copies to print. Always returned. | |
| 323 selected-page-button Which page button was selected (`all', `selection', | |
| 324 or `pages'). | |
| 442 | 325 |
| 326 The DEVICE is destroyed and an error is signaled in case of | |
| 327 initialization problem with the new printer. | |
| 328 | |
| 510 | 329 See also the `page-setup' dialog box type. |
| 442 | 330 |
| 331 --------------------------------------------------------------------------- | |
| 332 | |
| 333 For type `page-setup': | |
| 334 | |
| 335 This invokes the Windows standard Page Setup dialog. | |
| 506 | 336 This dialog is usually invoked in response to the Page Setup command, |
| 337 and used to choose such parameters as page orientation, print margins | |
| 338 etc. Note that this dialog contains the \"Printer\" button, which | |
| 339 invokes the Printer Setup dialog so that the user can update the | |
| 340 printer options or even select a different printer as well. | |
| 442 | 341 |
| 342 The keywords allowed are | |
| 343 | |
| 344 :device | |
| 345 An 'msprinter device. | |
| 346 :print-settings | |
| 347 A printer settings object. | |
| 348 :properties | |
| 349 A plist of job properties. | |
| 350 | |
| 351 Exactly one of these keywords must be given. | |
| 352 | |
| 353 The function brings up the Page Setup dialog, where the user | |
| 354 can select a different printer and/or change printer options. | |
| 355 Connection name can change as a result of selecting a different printer | |
| 506 | 356 device. If a device is specified, then changes are stored into the |
| 442 | 357 settings object currently selected into that printer. If a settings |
| 629 | 358 object is supplied, then changes are recorded into it, and, it is |
| 442 | 359 selected into a printer, then changes are propagated to that printer |
| 360 too. | |
| 361 | |
| 362 :properties specifies a plist of job properties; | |
| 363 see `default-msprinter-frame-plist' for the complete list. The plist | |
| 364 is used to initialize the dialog. | |
| 365 | |
| 366 Return value is nil if the user has canceled the dialog. Otherwise, | |
| 367 it is a new plist, containing the new list of properties. | |
| 368 | |
| 506 | 369 NOTE: The margin properties (returned by this function) are *NOT* stored |
| 370 into the print-settings or device object. | |
| 371 | |
| 442 | 372 The DEVICE is destroyed and an error is signaled in case of |
| 373 initialization problem with the new printer. | |
| 374 | |
| 510 | 375 See also the `print' dialog box type. |
| 442 | 376 |
| 377 --------------------------------------------------------------------------- | |
| 378 | |
| 379 For type `mswindows-message': | |
| 380 | |
| 381 The keywords allowed are | |
| 382 | |
| 383 :title | |
| 384 The title of the dialog box. | |
| 385 :message | |
| 386 The string to display. | |
| 387 :flags | |
| 388 A symbol or list of symbols: | |
| 389 | |
| 390 -- To specify the buttons in the message box: | |
| 391 | |
| 392 abortretryignore | |
| 393 The message box contains three push buttons: Abort, Retry, and Ignore. | |
| 394 ok | |
| 395 The message box contains one push button: OK. This is the default. | |
| 396 okcancel | |
| 397 The message box contains two push buttons: OK and Cancel. | |
| 398 retrycancel | |
| 399 The message box contains two push buttons: Retry and Cancel. | |

| 430 | |
| 431 -- To indicate the modality of the dialog box: | |
| 432 | |
| 433 applmodal | |
| 434 The user must respond to the message box before continuing work in | |
| 435 the window identified by the hWnd parameter. However, the user can | |
| 436 move to the windows of other applications and work in those windows. | |
| 437 Depending on the hierarchy of windows in the application, the user | |
| 438 may be able to move to other windows within the application. All | |
| 439 child windows of the parent of the message box are automatically | |
| 440 disabled, but popup windows are not. This is the default. | |
| 441 systemmodal | |
| 442 Same as applmodal except that the message box has the WS_EX_TOPMOST | |
| 443 style. Use system-modal message boxes to notify the user of serious, | |
| 444 potentially damaging errors that require immediate attention (for | |
| 445 example, running out of memory). This flag has no effect on the | |
| 446 user's ability to interact with windows other than those associated | |
| 447 with hWnd. | |
| 448 taskmodal | |
| 449 Same as applmodal except that all the top-level windows belonging to | |
| 450 the current task are disabled if the hWnd parameter is NULL. Use | |
| 451 this flag when the calling application or library does not have a | |
| 452 window handle available but still needs to prevent input to other | |
| 453 windows in the current application without suspending other | |
| 454 applications. | |
| 455 | |
| 456 | |
| 457 In addition, you can specify the following flags: | |
| 458 | |
| 459 default-desktop-only | |
| 460 The desktop currently receiving input must be a default desktop; | |
| 461 otherwise, the function fails. A default desktop is one an | |
| 462 application runs on after the user has logged on. | |
| 463 help | |
| 464 Adds a Help button to the message box. Choosing the Help button or | |
| 465 pressing F1 generates a Help event. | |
| 466 right | |
| 467 The text is right-justified. | |
| 468 rtlreading | |
| 469 Displays message and caption text using right-to-left reading order | |
| 470 on Hebrew and Arabic systems. | |
| 471 setforeground | |
| 472 The message box becomes the foreground window. Internally, Windows | |
| 473 calls the SetForegroundWindow function for the message box. | |
| 474 topmost | |
| 475 The message box is created with the WS_EX_TOPMOST window style. | |
| 476 service-notification | |
| 477 Windows NT only: The caller is a service notifying the user of an | |
| 478 event. The function displays a message box on the current active | |
| 479 desktop, even if there is no user logged on to the computer. If | |
| 480 this flag is set, the hWnd parameter must be NULL. This is so the | |
| 481 message box can appear on a desktop other than the desktop | |
| 482 corresponding to the hWnd. | |
| 483 | |
| 484 | |
| 485 The return value is one of the following menu-item values returned by | |
| 486 the dialog box: | |
| 487 | |
| 488 abort | |
| 489 Abort button was selected. | |
| 490 cancel | |
| 491 Cancel button was selected. | |
| 492 ignore | |
| 493 Ignore button was selected. | |
| 494 no | |
| 495 No button was selected. | |
| 496 ok | |
| 497 OK button was selected. | |
| 498 retry | |
| 499 Retry button was selected. | |
| 500 yes | |
| 501 Yes button was selected. | |
| 502 | |
| 503 If a message box has a Cancel button, the function returns the | |
| 504 `cancel' value if either the ESC key is pressed or the Cancel button | |
| 505 is selected. If the message box has no Cancel button, pressing ESC has | |
| 506 no effect." | |
