Method Detail

addTreeModelListener
public void addTreeModelListener(TreeModelListener l)
Adds a listener for theTreeModelEvent
posted after the tree changes.- Specified by:
addTreeModelListener
in interfaceTreeModel
- Parameters:
l
- the listener to add- See Also:
removeTreeModelListener(javax.swing.event.TreeModelListener)
-
getChild
public Object getChild(Object parent, int index)
Returns the child ofparent
at indexindex
in the parent's child array.parent
must be a node previously obtained from this data source. This should not returnnull
ifindex
is a valid index forparent
(that isindex >= 0 && index < getChildCount(parent
)).
-
getChildCount
public int getChildCount(Object parent)
Returns the number of children ofparent
. Returns 0 if the node is a leaf or if it has no children.parent
must be a node previously obtained from this data source.- Specified by:
getChildCount
in interfaceTreeModel
- Parameters:
parent
- a node in the tree, obtained from this data source- Returns:
- the number of children of the node
parent
-
getIndexOfChild
public int getIndexOfChild(Object parent, Object child)
Returns the index of child in parent. Ifparent
isnull
orchild
isnull
, returns -1.- Specified by:
getIndexOfChild
in interfaceTreeModel
- Parameters:
parent
- a note in the tree, obtained from this data sourcechild
- the node we are interested in- Returns:
- the index of the child in the parent, or -1 if either
child
orparent
arenull
-
getRoot
public Object getRoot()
Returns the root of the tree. Returnsnull
only if the tree has no nodes.
-
isLeaf
public boolean isLeaf(Object node)
Returnstrue
ifnode
is a leaf. It is possible for this method to returnfalse
even ifnode
has no children. A directory in a filesystem, for example, may contain no files; the node representing the directory is not a leaf, but it also has no children.
-
removeTreeModelListener
public void removeTreeModelListener(TreeModelListener l)
Removes a listener previously added withaddTreeModelListener
.- Specified by:
removeTreeModelListener
in interfaceTreeModel
- Parameters:
l
- the listener to remove- See Also:
addTreeModelListener(javax.swing.event.TreeModelListener)
-
valueForPathChanged
public void valueForPathChanged(TreePath path, Object newValue)
Messaged when the user has altered the value for the item identified bypath
tonewValue
. IfnewValue
signifies a truly new value the model should post atreeNodesChanged
event.- Specified by:
valueForPathChanged
in interfaceTreeModel
- Parameters:
path
- path to the node that the user has alterednewValue
- the new value from the TreeCellEditor
