fs28 NSPageLayout is a type of NSPanel that queries the user for information such as paper type and orientation. This information is stored in an NSPrintInfo object, and is later used when printing. The NSPageLayout panel is created, displayed, and run (in a modal loop) when a b runPageLayout:b0 message is sent to the NSApplication object. By default, this message is sent up the responder chain when the user clicks the Page Layout menu item.

fs28 Typically, you access an NSPageLayout panel by invoking the b pageLayoutb0 method. When the class receives a b pageLayoutb0 message, it tries to reuse an existing panel rather than create a new one. If 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 Page Layout panels may be reused, you shouldn'27t modify the instance returned by b pageLayoutb0 , except through the methods listed below. If you must modify the Page Layout panel in other ways than those allowed by its methods, create and manage your own instance using the b alloc...b0 and b init...b0 methods rather than the b pageLayoutb0 method.

fs28 You can add your own controls to the Page Layout panel through the b setAccessoryView:b0 method. The panel is automatically resized to accommodate the NSView that you'27ve added. Note that you can'27t retrieve the NSPageLayout'27s settings through messages to the page layout panel object'd0NSPageLayout does not have accessor methods to obtain the state of its controls. If controls you add through an accessory view need to know the values of the existing controls in the page layout panel (or vice versa), access NSPageLayout'27s controls using the tags defined in fs28 AppKit/NSPageLayout.hfs28 as arguments to b viewWithTag:b0 messages to the page layout panel object. Controls thus returned can then be queried for their state.
