Constructor Detail

AbstractJPPFTreeTableModel

public AbstractJPPFTreeTableModel(TreeNode root)

Initialize this model with the specified tree root.

Parameters:

root - - the root of the tree.

Method Detail

isCellEditable

public boolean isCellEditable(Object node,
                              int column)

Tells if a cell can be edited.

Specified by:

isCellEditable in interface TreeTableModel

Overrides:

isCellEditable in class AbstractTreeTableModel

Parameters:

node - not used.

column - not used.

Returns:

true if the cell can be edited, false otherwise.

See Also:

AbstractTreeTableModel.isCellEditable(java.lang.Object, int)

setValueAt

public void setValueAt(Object value,
                       Object node,
                       int column)

Called when done editing a cell. This method has an empty implementation and does nothing.

Specified by:

setValueAt in interface TreeTableModel

Overrides:

setValueAt in class AbstractTreeTableModel

Parameters:

value - not used.

node - not used.

column - not used.

See Also:

AbstractTreeTableModel.setValueAt(java.lang.Object, java.lang.Object, int)

getChild

public Object getChild(Object parent,
                       int index)

Return the child at the specified index from the specified parent node.

Parameters:

parent - the parent to get the child from.

index - the index at which to get the child

Returns:

the child node, or null if the index is not valid.

See Also:

TreeModel.getChild(java.lang.Object, int)

getChildCount

public int getChildCount(Object parent)

Get the number of children for the specified node.

Parameters:

parent - the node for which to get the number of children.

Returns:

the number of children as an int.

See Also:

TreeModel.getChildCount(java.lang.Object)

insertNodeInto

public void insertNodeInto(DefaultMutableTreeNode child,
                           DefaultMutableTreeNode parent,
                           int pos)

Insert the specified child into the specified parent's list of children at the specified position.

Parameters:

child - - the node to insert into the parent.

parent - - the node into which to insert the child.

pos - - the position at which to insert the node.

removeNodeFromParent

public void removeNodeFromParent(DefaultMutableTreeNode node)

localize

protected String localize(String message)

Get a localized message given its unique name and the current locale.

Parameters:

message - the unique name of the localized message.

Returns:

a message in the current locale, or the default locale if the localization for the current locale is not found.
