18 A dialog box description is a list.
22 The first element of the list is a string to display in the dialog box.
24 The rest of the elements are descriptions of the dialog box's buttons.
25 Each one is a vector of three elements:
28 The first element is the text of the button.
30 The second element is the @dfn{callback}.
32 The third element is @code{t} or @code{nil}, whether this button is
37 If the callback of a button is a symbol, then it must name a command.
38 It will be invoked with @code{call-interactively}. If it is a list,
39 then it is evaluated with @code{eval}.
41 One (and only one) of the buttons may be @code{nil}. This marker means
42 that all following buttons should be flushright instead of flushleft.
44 The syntax, more precisely:
47 form := <something to pass to `eval'>
48 command := <a symbol or string, to pass to `call-interactively'>
49 callback := command | form
50 active-p := <t, nil, or a form to evaluate to decide whether this
51 button should be selectable>
54 button := '[' name callback active-p ']'
55 dialog := '(' name [ button ]+ [ partition [ button ]+ ] ')'
