fireTreeNodesChanged

protected void fireTreeNodesChanged(Object source,
                                    Object[] path,
                                    int[] childIndices,
                                    Object[] children)

Notify all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.

Parameters:

source - the source of the event.

path - the path of the parent node whose children have changed.

childIndices - the indices of the children that changed.

children - an array of the children that changed.

getColumnClass

public Class getColumnClass(int column)

Returns the type for column number column.

Specified by:

getColumnClass in interface TreeTableModel

Parameters:

column - the column number.

Returns:

the type of the column.

isCellEditable

public boolean isCellEditable(Object node,
                              int column)

By default, make the column with the Tree in it the only editable one. Making this column editable causes the JTable to forward mouse and keyboard events in the Tree column to the underlying JTree. Indicates whether the the value for node node, at column number column is editable.

Specified by:

isCellEditable in interface TreeTableModel

Parameters:

node - the node to check.

column - the column where the value is.

Returns:

true if the cell is editable, false otherwise.

setValueAt

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

Sets the value for node node, at column number column.

Specified by:

setValueAt in interface TreeTableModel

Parameters:

aValue - the value to set.

node - the node for which to set the value.

column - the column where the value is to be set.
