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