public class JInsertPosition
extends Component
implements InsertPosition, DocumentListener, ActionListener
An implementation of InsertPosition for a view that maps over the entire portion of the model represented (ie there are no holes in the area represented) and renders the insert position as a vertical line. The foreground color of the component is the color of the caret and the background color of the component is the color of the selections made by moving the caret. The Highlighter implementation of the associated UI is used to actually render the selection.

Variables

o changeListener 
 protected ChangeListener changeListener
o changeEvent 
 protected ChangeEvent changeEvent

Constructors

o JInsertPosition 
 public JInsertPosition(Color c,
                        Color h)
Construct a caret with given color settings.

Parameters:
c - The caret color
h - The highlight color for selections (ie. indicating the range spaned by the dot/mark combination).

Methods

o damage 
 protected void damage(Rectangle r)
Damages the area surrounding the caret to cause it to be repainted. If paint() is reimplemented, this method should also be reimplemented.

Parameters:
r - The current location of the caret.

o adjustHorizontally 
 protected void adjustHorizontally(BoundedRangeModel vis,
                                   Rectangle oloc,
                                   Rectangle nloc)
Scroll the associated view horizontally to make the caret visible. Since how this should be done is somewhat of a policy, this method can be reimplemented to change the behavior. By default an attempt will be made to scroll the view so the caret is in it's previous location.

o adjustVertically 
 protected void adjustVertically(BoundedRangeModel vis,
                                 Rectangle oloc,
                                 Rectangle nloc)
Scroll the associated view vertically to make the caret visible. Since how this should be done is somewhat of a policy, this method can be reimplemented to change the behavior. By default an attempt will be made to scroll the view so the caret is in it's previous location.

o paint 
 public void paint(Graphics g)
Renders the caret as a vertical line. If this is reimplemented the damage method should also be reimplemented as it assumes the shape of the caret is a vertical line.

Overrides:
paint in class Component

damage
o actionPerformed 
 public void actionPerformed(ActionEvent e)

o insertUpdate 
 public void insertUpdate(DocumentEvent e)
