Package jmri.jmrit.catalog

Class CatalogTreeModel

java.lang.Object

javax.swing.tree.DefaultTreeModel

jmri.jmrit.catalog.CatalogTreeModel

All Implemented Interfaces:

Serializable, TreeModel, InstanceManagerAutoDefault

public class CatalogTreeModel
extends DefaultTreeModel
implements InstanceManagerAutoDefault

TreeModel used by CatalogPane to create a tree of resources.

Accessed via the instance() member, as we expect to have only one of these models.

The tree has two top-level visible nodes. One, "icons", represents the contents of the icons directory in the resources tree in the .jar file. The other, "files", is all files found in the "resources" filetree in the preferences directory. Note that this means that files in the distribution directory are _not_ included.

As a special case "simplification", the catalog tree will not contain CVS directories, or files whose name starts with a "."

insertResourceNodes

void insertResourceNodes(String pName,
 String pPath,
 DefaultMutableTreeNode pParent)

Recursively add a representation of the resources below a particular resource

Parameters:

pName - Name of the resource to be scanned; this is only used for the human-readable tree

pPath - Path to this resource, including the pName part

pParent - Node for the parent of the resource to be scanned, e.g. where in the tree to insert it.

insertFileNodes

void insertFileNodes(String name,
 String path,
 DefaultMutableTreeNode parent)

Recursively add a representation of the files below a particular file

Parameters:

name - Name of the file to be scanned

path - the path to the file

parent - Node for the parent of the file to be scanned
