public class ConnectingLinePointHandle

extends LinePointHandle

This class provides a handle that shows up at a particular Locator on a line and reshapes the figure accordingly as it is dragged, potentially turning the specific locator into one relative to another figure.

Constructor Summary

ConnectingLinePointHandle(LineFigure figure, int index)
Constructs and initializes a new instance of a handle which can affect the the position of a particular point defining a line and connect that point to a figure if appropriate.

Method Summary

protected boolean	isConnected() Answer whether the handle's locator is connected to a figure (or about to request it).
void	mouseReleased(java.awt.event.MouseEvent evt) Called if the mouse goes up.
void	paint(java.awt.Graphics g) Paints the handle.

Constructor Detail

ConnectingLinePointHandle

public ConnectingLinePointHandle(LineFigure figure,
                                 int index)

Constructs and initializes a new instance of a handle which can affect the the position of a particular point defining a line and connect that point to a figure if appropriate.

Parameters:

figure - the figure whose point (vertex) we may wish to modify.

index - the identifying index of the point of interest.

Method Detail

isConnected

protected boolean isConnected()

Answer whether the handle's locator is connected to a figure (or about to request it).

Returns:

boolean value of true if the handle's locator is connected to a figure (or about to request it); false otherwise.

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent evt)

Called if the mouse goes up. If there is a figure at the given point, connect to it if possible before giving up control.

Overrides:

mouseReleased in class LinePointHandle

Parameters:

evt - the event

paint

public void paint(java.awt.Graphics g)

Paints the handle.

Overrides:

paint in class SquareCanvasHandle

Parameters:

g - the specified Graphics window
