NodeTreeNodeRenderer

public NodeTreeNodeRenderer(VisibleCtls visibleCtls)

Method Details

getTreeCellRendererComponent

public Component getTreeCellRendererComponent(JTree tree,
 Object value,
 boolean selected,
 boolean expanded,
 boolean leaf,
 int row,
 boolean hasFocus)

Sets the value of the current tree cell to value. If selected is true, the cell will be drawn as if selected. If expanded is true the node is currently expanded and if leaf is true the node represents a leaf and if hasFocus is true the node currently has focus. tree is the JTree the receiver is being configured for. Returns the Component that the renderer uses to draw the value.

The TreeCellRenderer is also responsible for rendering the the cell representing the tree's current DnD drop location if it has one. If this renderer cares about rendering the DnD drop location, it should query the tree directly to see if the given row represents the drop location: JTree.DropLocation dropLocation = tree.getDropLocation(); if (dropLocation != null && dropLocation.getChildIndex() == -1 && tree.getRowForPath(dropLocation.getPath()) == row) { // this row represents the current drop location // so render it specially, perhaps with a different color }

Specified by:

getTreeCellRendererComponent in interface TreeCellRenderer

Returns:

the Component that the renderer uses to draw the value

getTreeCellEditorComponent

public Component getTreeCellEditorComponent(JTree tree,
 Object value,
 boolean isSelected,
 boolean expanded,
 boolean leaf,
 int row)

Sets an initial value for the editor. This will cause the editor to stopEditing and lose any partially edited value if the editor is editing when this method is called.

Returns the component that should be added to the client's Component hierarchy. Once installed in the client's hierarchy this component will then be able to draw and receive user input.

Specified by:

getTreeCellEditorComponent in interface TreeCellEditor

Parameters:

tree - the JTree that is asking the editor to edit; this parameter can be null

value - the value of the cell to be edited

isSelected - true if the cell is to be rendered with selection highlighting

expanded - true if the node is expanded

leaf - true if the node is a leaf node

row - the row index of the node being edited

Returns:

the component for editing

getCellEditorValue

public Object getCellEditorValue()

Returns the value contained in the editor.

Specified by:

getCellEditorValue in interface CellEditor

Returns:

the value contained in the editor

isCellEditable

public boolean isCellEditable(EventObject anEvent)

Asks the editor if it can start editing using anEvent. anEvent is in the invoking component coordinate system. The editor can not assume the Component returned by getCellEditorComponent is installed. This method is intended for the use of client to avoid the cost of setting up and installing the editor component if editing is not possible. If editing can be started this method returns true.

Specified by:

isCellEditable in interface CellEditor

Parameters:

anEvent - the event the editor should use to consider whether to begin editing or not

Returns:

true if editing can be started

See Also:

• shouldSelectCell(java.util.EventObject)

shouldSelectCell

public boolean shouldSelectCell(EventObject anEvent)

Returns true if the editing cell should be selected, false otherwise. Typically, the return value is true, because is most cases the editing cell should be selected. However, it is useful to return false to keep the selection from changing for some types of edits. eg. A table that contains a column of check boxes, the user might want to be able to change those checkboxes without altering the selection. (See Netscape Communicator for just such an example) Of course, it is up to the client of the editor to use the return value, but it doesn't need to if it doesn't want to.

Specified by:

shouldSelectCell in interface CellEditor

Parameters:

anEvent - the event the editor should use to start editing

Returns:

true if the editor would like the editing cell to be selected; otherwise returns false

See Also:

• isCellEditable(java.util.EventObject)

stopCellEditing

public boolean stopCellEditing()

Tells the editor to stop editing and accept any partially edited value as the value of the editor. The editor returns false if editing was not stopped; this is useful for editors that validate and can not accept invalid entries.

Specified by:

stopCellEditing in interface CellEditor

Returns:

true if editing was stopped; false otherwise

cancelCellEditing

public void cancelCellEditing()

Tells the editor to cancel editing and not accept any partially edited value.

Specified by:

cancelCellEditing in interface CellEditor

addCellEditorListener

public void addCellEditorListener(CellEditorListener l)

Adds a listener to the list that's notified when the editor stops, or cancels editing.

Specified by:

addCellEditorListener in interface CellEditor

Parameters:

l - the CellEditorListener

removeCellEditorListener

public void removeCellEditorListener(CellEditorListener l)

Removes a listener from the list that's notified

Specified by:

removeCellEditorListener in interface CellEditor

Parameters:

l - the CellEditorListener

itemStateChanged

public void itemStateChanged(ItemEvent e)

Invoked when an item has been selected or deselected by the user. The code written for this method performs the operations that need to occur when an item is selected (or deselected).

Specified by:

itemStateChanged in interface ItemListener
