123 TYPE is a symbol, the type of dialog box. Remaining arguments are

124 keyword-value pairs, specifying the particular characteristics of the
|
|
|
125 dialog box. The allowed keywords are particular to each type, but
|
|
|
126 some standard keywords are common to many types:
|
|
|
127
|
|
|
128 :title
|
|
|
129 The title of the dialog box's window.
|
|
|
130
|
|
|
131 :modal
|
|
|
132 If true, indicates that XEmacs will wait until the user is \"done\"
|
|
|
133 with the dialog box (usually, this means that a response has been
|
|
|
134 given). Typically, the response is returned. NOTE: Some dialog
|
|
|
135 boxes are always modal. If the dialog box is modal, `make-dialog-box'
|
|
|
136 returns immediately. The return value will be either nil or a
|
|
|
137 dialog box handle of some sort, e.g. a frame for type `general'.
|
|
|
138
|
|
|
139 ---------------------------------------------------------------------------
|
|
|
140
|
|
|
141 Recognized types are
|
|
|
142
|
|
|
143 general
|
|
|
144 A dialog box consisting of an XEmacs glyph, typically a `layout'
|
|
|
145 widget specifying a dialog box arrangement. This is the most
|
|
|
146 general and powerful dialog box type, but requires more work than
|
|
|
147 the other types below.
|
|
|
148
|
|
|
149 question
|
|
|
150 A simple dialog box that displays a question and contains one or
|
|
|
151 more user-defined buttons to specify possible responses. (This is
|
|
|
152 compatible with the old built-in dialog boxes formerly specified
|
|
|
153 using `popup-dialog-box'.)
|
|
|
154
|
|
|
155 file
|
|
|
156 A file dialog box, of the type typically used in the window system
|
|
|
157 XEmacs is running on.
|
|
|
158
|
|
|
159 color
|
|
|
160 A color picker.
|
|
|
161
|
|
|
162 find
|
|
|
163 A find dialog box.
|
|
|
164
|
|
|
165 font
|
|
|
166 A font chooser.
|
|
|
167
|
|
|
168 print
|
|
|
169 A dialog box used when printing (e.g. number of pages, printer).
|
|
|
170
|
|
|
171 page-setup
|
|
|
172 A dialog box for setting page options (e.g. margins) for printing.
|
|
|
173
|
|
|
174 replace
|
|
|
175 A find/replace dialog box.
|
|
|
176
|
|
|
177 mswindows-message
|
|
|
178 An MS Windows-specific standard dialog box type similar to `question'.
|
|
|
179
|
|
|
180 ---------------------------------------------------------------------------
|
|
|
181
|
|
|
182 For type `general':
|
|
|
183
|
|
|
184 This type creates a frame and puts the specified widget layout in it.
|
|
|
185 \(Currently this is done by eliminating all areas but the gutter and placing
|
|
|
186 the layout there; but this is an implementation detail and may change.)
|
|
|
187
|
|
|
188 The keywords allowed for `general' are
|
|
|
189
|
|
|
190 :spec
|
|
|
191 The widget spec -- anything that can be passed to `make-glyph'.
|
|
|
192 :title
|
|
|
193 The title of the frame.
|
|
|
194 :parent
|
|
|
195 The frame is made a child of this frame (defaults to the selected frame).
|
|
|
196 :properties
|
|
|
197 Additional properties of the frame, as well as `dialog-frame-plist'.
|
|
|
198
|
|
|
199 ---------------------------------------------------------------------------
|
|
|
200
|
|
|
201 For type `question':
|
|
|
202
|
|
|
203 The keywords allowed are
|
|
|
204
|
|
|
205 :modal
|
|
|
206 t or nil. When t, the dialog box callback should exit the dialog box
|
|
|
207 using the functions `dialog-box-finish' or `dialog-box-cancel'.
|
|
|
208 :title
|
|
|
209 The title of the frame.
|
|
|
210 :question
|
|
|
211 A string, the question.
|
|
|
212 :buttons
|
|
|
213 A list, describing the buttons below the question. Each of these is a
|
|
|
214 vector, the syntax of which is essentially the same as that of popup menu
|
|
|
215 items. They may have any of the following forms:
|
|
|
216
|
|
|
217 [ \"name\" callback <active-p> ]
|
|
|
218 [ \"name\" callback <active-p> \"suffix\" ]
|
|
|
219 [ \"name\" callback :<keyword> <value> :<keyword> <value> ... ]
|
|
|
220
|
|
|
221 The name is the string to display on the button; it is filtered through the
|
|
|
222 resource database, so it is possible for resources to override what string
|
|
|
223 is actually displayed.
|
|
|
224
|
|
|
225 Accelerators can be indicated in the string by putting the sequence
|
|
|
226 \"%_\" before the character corresponding to the key that will invoke
|
|
|
227 the button. Uppercase and lowercase accelerators are equivalent. The
|
|
|
228 sequence \"%%\" is also special, and is translated into a single %.
|
|
|
229
|
|
|
230 If the `callback' of a button is a symbol, then it must name a command.
|
|
|
231 It will be invoked with `call-interactively'. If it is a list, then it is
|
|
|
232 evaluated with `eval'.
|
|
|
233
|
|
|
234 One (and only one) of the buttons may be `nil'. This marker means that all
|
|
|
235 following buttons should be flushright instead of flushleft.
|
|
|
236
|
|
|
237 Though the keyword/value syntax is supported for dialog boxes just as in
|
|
|
238 popup menus, the only keyword which is both meaningful and fully implemented
|
|
|
239 for dialog box buttons is `:active'.
|
|
|
240
|
|
|
241 ---------------------------------------------------------------------------

|
|
242
|
|
|
243 For type `file':

|
|
|
248 The initial filename to be placed in the dialog box (defaults to nothing).
|
|
|
249 :initial-directory
|
|
|
250 The initial directory to be selected in the dialog box (defaults to the
|
|
|
251 current buffer's `default-directory).

|
|
252 :filter-list
|
|
|
253 A list of (filter-desc filter ...)

277 For type `print':
|
|
|
278
|
|
|
279 This invokes the Windows standard Print dialog.
|
|
|
280 This dialog is usually invoked when the user selects the Print command.
|
|
|
281 After the user presses OK, the program should start actual printout.

299
|
|
|
300 The function brings up the Print dialog, where the user can
|
|
506
|
301 select a different printer and/or change printer options. Connection
|
|
442
|
302 name can change as a result of selecting a different printer device. If
|
|
506
|
303 a device is specified, then changes are stored into the settings object
|
|
442
|
304 currently selected into that printer. If a settings object is supplied,
|
|
629
|
305 then changes are recorded into it, and, it is selected into a
|
|
442
|
306 printer, then changes are propagated to that printer
|
|
|
307 too.

331 This dialog is usually invoked in response to the Page Setup command,
|
|
|
332 and used to choose such parameters as page orientation, print margins
|
|
|
333 etc. Note that this dialog contains the \"Printer\" button, which
|
|
|
334 invokes the Printer Setup dialog so that the user can update the

389 ok
|
|
|
390 The message box contains one push button: OK. This is the default.

401 -- To display an icon in the message box:
|
|
|
402
|
|
|
403 iconexclamation, iconwarning
|
|
|
404 An exclamation-point icon appears in the message box.
|
|
|
405 iconinformation, iconasterisk
|
|
|
406 An icon consisting of a lowercase letter i in a circle appears in
|
|
|
407 the message box.
|
|
|
408 iconquestion
|
|
|
409 A question-mark icon appears in the message box.
|
|
|
410 iconstop, iconerror, iconhand
|
|
|
411 A stop-sign icon appears in the message box.
|
|
|
412

|
414 -- To indicate the default button:
|
|
|
415

419 The second button is the default button.

421 The third button is the default button.
|

422 defbutton4
|
|
|
423 The fourth button is the default button.
|
|
|
424
|
|
|
425
|
|
|
426 -- To indicate the modality of the dialog box:
|
|
|
427
|
|
|
428 applmodal
|
|
|
429 The user must respond to the message box before continuing work in
|
|
|
430 the window identified by the hWnd parameter. However, the user can
|
|
|
431 move to the windows of other applications and work in those windows.
|
|
|
432 Depending on the hierarchy of windows in the application, the user
|
|
|
433 may be able to move to other windows within the application. All
|
|
|
434 child windows of the parent of the message box are automatically
|
|
|
435 disabled, but popup windows are not. This is the default.
|
|
|
436 systemmodal
|
|
|
437 Same as applmodal except that the message box has the WS_EX_TOPMOST
|
|
|
438 style. Use system-modal message boxes to notify the user of serious,
|
|
|
439 potentially damaging errors that require immediate attention (for
|
|
|
440 example, running out of memory). This flag has no effect on the
|
|
|
441 user's ability to interact with windows other than those associated
|
|
|
442 with hWnd.
|
|
|
443 taskmodal
|
|
|
444 Same as applmodal except that all the top-level windows belonging to
|
|
|
445 the current task are disabled if the hWnd parameter is NULL. Use
|
|
|
446 this flag when the calling application or library does not have a
|
|
|
447 window handle available but still needs to prevent input to other
|
|
|
448 windows in the current application without suspending other
|
|
|
449 applications.
|
|
|
450
|
|
|
451
|
|
|
452 In addition, you can specify the following flags:
|
|
|
453
|
|
|
454 default-desktop-only
|
|
|
455 The desktop currently receiving input must be a default desktop;
|
|
|
456 otherwise, the function fails. A default desktop is one an
|
|
|
457 application runs on after the user has logged on.
|
|
|
458 help
|
|
|
459 Adds a Help button to the message box. Choosing the Help button or
|
|
|
460 pressing F1 generates a Help event.
|
|
|
461 right
|
|
|
462 The text is right-justified.
|
|
|
463 rtlreading
|
|
|
464 Displays message and caption text using right-to-left reading order
|
|
|
465 on Hebrew and Arabic systems.
|
|
|
466 setforeground
|
|
|
467 The message box becomes the foreground window. Internally, Windows
|
|
|
468 calls the SetForegroundWindow function for the message box.
|
|
|
469 topmost
|
|
|
470 The message box is created with the WS_EX_TOPMOST window style.
|
|
|
471 service-notification
|
|
|
472 Windows NT only: The caller is a service notifying the user of an
|
|
|
473 event. The function displays a message box on the current active
|
|
|
474 desktop, even if there is no user logged on to the computer. If
|
|
|
475 this flag is set, the hWnd parameter must be NULL. This is so the
|
|
|
476 message box can appear on a desktop other than the desktop
|
|
|
477 corresponding to the hWnd.
|
|
|
478
|
|
|
479
|
|
|
480 The return value is one of the following menu-item values returned by
|
|
|
481 the dialog box:
|
|
|
482
|
|
|
483 abort
|
|
|
484 Abort button was selected.
|
|
|
485 cancel
|
|
|
486 Cancel button was selected.
|
|
|
487 ignore
|
|
|
488 Ignore button was selected.
|
|
|
489 no
|
|
|
490 No button was selected.
|
|
|
491 ok
|
|
|
492 OK button was selected.
|
|
|
493 retry
|
|
|
494 Retry button was selected.
|
|
|
495 yes
|
|
|
496 Yes button was selected.
|
|
|
497
|
|
|
498 If a message box has a Cancel button, the function returns the
|
|
|
499 `cancel' value if either the ESC key is pressed or the Cancel button
|
|
|
500 is selected. If the message box has no Cancel button, pressing ESC has
|
|
|
501 no effect."
