explore

public abstract void explore(Node n)
Explore a node (and its subhierarchy). It will be opened in a new Explorer view, as the root node of that window.

Parameters:
n - the node to explore

showProperties

public abstract void showProperties(Node n)
Open a modal Property Sheet on a node.

Parameters:
n - the node to show properties of

showProperties

public abstract void showProperties(Node[] n)
Open a modal Property Sheet on a set of nodes.

Parameters:
n - the array of nodes to show properties of

select

public abstract Node[] select(String title,
                              String rootTitle,
                              Node root,
                              NodeAcceptor acceptor,
                              Component top)
                       throws UserCancelException
Open a modal Explorer on a root node, permitting a node selection to be returned.

The acceptor should be asked each time the set of selected nodes changes, whether to accept or reject the current result. This will affect for example the display of the "OK" button.

Parameters:
title - title of the dialog
rootTitle - label at root of dialog. May use & for a mnemonic.
root - root node to explore
acceptor - class asked to accept or reject current selection
top - an extra component to be placed on the dialog (may be null)
Returns:
an array of selected (and accepted) nodes
Throws:
UserCancelException - if the selection is interrupted by the user

select

public Node[] select(String title,
                     String rootTitle,
                     Node root,
                     NodeAcceptor acceptor)
              throws UserCancelException
Open a modal Explorer without any extra dialog component.

Parameters:
title - title of the dialog
rootTitle - label at root of dialog. May use & for a mnemonic.
root - root node to explore
acceptor - class asked to accept or reject current selection
Returns:
an array of selected (and accepted) nodes
Throws:
UserCancelException - if the selection is interrupted by the user
See Also:
select(String, String, Node, NodeAcceptor, Component)

select

public final Node select(String title,
                         String rootTitle,
                         Node root)
                  throws UserCancelException
Open a modal Explorer accepting only a single node.

Parameters:
title - title of the dialog
rootTitle - label at root of dialog. May use & for a mnemonic.
root - root node to explore
