Inherits From: NSPanel : NSWindow : NSResponder : NSObject

Conforms To: NSCoding (NSResponder) NSObject (NSObject)

Declared In: AppKit/NSSavePanel.h

Class Description

NSSavePanel creates a Save panel. The Save panel provides a simple way for a user to specify a file to use when saving a document or other data. It can restrict the user to files of a certain type, as specified by a file name extension.

When the user decides on a file name, the message panel:isValidFilename: is sent to the NSSavePanel's delegate (if it responds to that message). The delegate can then determine whether that file name can be used; it returns YES if the file name is valid, or NO if the Save panel should stay up and wait for the user to type in a different file name.

Typically, you access an NSSavePanel by invoking the savePanel method. When the class receives a savePanel message, it tries to reuse an existing panel rather than create a new one. When a panel is reused, its attributes are reset to the default values so that the effect is the same as receiving a new panel. Because a Save panel may be reused, you shouldn't modify the instance returned by savePanel, except through the methods listed below. For example, you can set the panel's title and required file type, but not the arrangement of the buttons within the panel. If you must modify the Save panel substantially, create and manage your own instance using the alloc... and init... methods rather than the savePanel method.
