Dialogs
Mac OS applications use
dialogs to tell you things and get information from you. Think of them as the way your computer has a conversationor dialogwith you.
Mac OS X has three main types of dialogs:
Modeless dialogs enable you to work with the dialog while interacting with document windows. These dialogs usually have their own window controls to close and move them (Figure 40 ).
Figure 40. This Spelling dialog in TextEdit is an example of a modeless dialogyou can interact with the document while the dialog is displayed.
Document modal dialogs usually appear as dialog
sheets attached to a document window (Figure 41 ). You must address and dismiss these dialogs before you can continue working with the window, although you can switch to another window or application while the dialog is displayed.

Application modal dialogs appear as movable dialogs (Figure 42 ). These dialogs must be addressed and dismissed before you can continue working with the application, although you can switch to another application while the dialog is displayed.
