|
30 Pop up a dialog box.
|
|
|
31 A dialog box description is a list.
|
|
|
32
|
|
|
33 The first element of a dialog box must be a string, which is the title or
|
|
|
34 question.
|
|
|
35
|
|
|
36 The rest of the elements are descriptions of the dialog box's buttons.
|
|
|
37 Each of these is a vector, the syntax of which is essentially the same as
|
|
|
38 that of popup menu items. They may have any of the following forms:
|
|
|
39
|
|
|
40 [ "name" callback <active-p> ]
|
|
|
41 [ "name" callback <active-p> "suffix" ]
|
|
|
42 [ "name" callback :<keyword> <value> :<keyword> <value> ... ]
|
|
|
43
|
|
|
44 The name is the string to display on the button; it is filtered through the
|
|
|
45 resource database, so it is possible for resources to override what string
|
|
|
46 is actually displayed.
|
|
|
47
|
|
404
|
48 Accelerators can be indicated in the string by putting the sequence
|
|
|
49 "%_" before the character corresponding to the key that will invoke
|
|
|
50 the button. Uppercase and lowercase accelerators are equivalent. The
|
|
|
51 sequence "%%" is also special, and is translated into a single %.
|
|
|
52
|
|
284
|
53 If the `callback' of a button is a symbol, then it must name a command.
|
|
|
54 It will be invoked with `call-interactively'. If it is a list, then it is
|
|
|
55 evaluated with `eval'.
|
|
|
56
|
|
|
57 One (and only one) of the buttons may be `nil'. This marker means that all
|
|
|
58 following buttons should be flushright instead of flushleft.
|
|
|
59
|
|
|
60 Though the keyword/value syntax is supported for dialog boxes just as in
|
|
|
61 popup menus, the only keyword which is both meaningful and fully implemented
|
|
404
|
62 for dialog box buttons is `:active'. */
