11 * This is the interface to the embeddable prompt service; the service that
12 * implements nsIPrompt. Its interface is designed to be just nsIPrompt, each
13 * method modified to take a parent window parameter.
14 *
15 * Accesskeys can be attached to buttons and checkboxes by inserting an &
16 * before the accesskey character in the checkbox message or button title. For
17 * a real &, use && instead. (A "button title" generally refers to the text
18 * label of a button.)
19 *
20 * One note: in all cases, the parent window parameter can be null. However,
21 * these windows are all intended to have parents. So when no parent is
22 * specified, the implementation should try hard to find a suitable foster
23 * parent.
24 *
25 * Implementations are free to choose how they present the various button
26 * types. For example, while prompts that give the user a choice between OK
27 * and Cancel are required to return a boolean value indicating whether or not
28 * the user accepted the prompt (pressed OK) or rejected the prompt (pressed
29 * Cancel), the implementation of this interface could very well speak the
30 * prompt to the user instead of rendering any visual user-interface. The
31 * standard button types are merely idioms used to convey the nature of the
32 * choice the user is to make.
33 *
34 * Because implementations of this interface may loosely interpret the various
35 * button types, it is advised that text messages passed to these prompts do
36 * not refer to the button types by name. For example, it is inadvisable to
37 * tell the user to "Press OK to proceed." Instead, such a prompt might be
38 * rewritten to ask the user: "Would you like to proceed?"
