public class DocumentPrintFactory
extends java.lang.Object
A base class for handling printing from a view. Some views will extend
this class so they can override methods to provide a more view-specific
implementation. For example, in the Navigator it's important to override
isPrintingEnabled() to only return true if at least one selected element
is printable.
The method that will be called by the PrintManager in response to the
the print command. The code which implements this will need to do the
appropriate action based on the view that is being asked to print.
For example, in the Navigator this call would need to determine which
nodes are selected and of those, which are printable. For each node
it would then get the Node for the node and call the PrintManager's
method to create a Pageable for each Node.
This method will be called by the PrintManager to determine if the
File->Print menu option should be enabled. The default implementation
is to have the menu option enabled, but if the menu option needs to be
enabled/disabled based on additional information then the view's
DocumentPrintFactory should override this method. For example, the
NavigatorController determines if File->Print should be enabled based
on what is selected in the Navigator window.
