Constructor Detail

NodeAndLinkAnimatingJPanel

public NodeAndLinkAnimatingJPanel()

Sole Constructor for the JPanel that paints the node using the AnimatingTree drawNode method. The JPanel only makes a new image on a resize and otherwise, double-buffers the graphics by leaving the image unmodified.

Method Detail

isDrawingLines

public boolean isDrawingLines()

Gets whether the animation is drawing lines or a node. If the panel is drawing lines, returns true.

Returns:

true if the panel is drawing lines.

getAnimatingNode

public DrawingTree<P> getAnimatingNode()

Gets the head of the tree currently drawn in the Panel.

Returns:

TreeHead the tree head.

getRightLinePaint

public java.awt.Paint getRightLinePaint()

Gets the paint for the right line drawing.

Returns:

Paint right Line Paint.

getLeftLinePaint

public java.awt.Paint getLeftLinePaint()

Gets the paint for the left line drawing.

Returns:

Paint left Line Paint.

setDrawingLines

public void setDrawingLines(boolean drawingLines)

Sets whether the animation is drawing lines or a node. If the panel is drawing lines, sets true.

Parameters:

drawingLines - true if the panel is drawing lines.

setRightLinePaint

public void setRightLinePaint(java.awt.Paint rightLinePaint)

Sets the paint for the right line drawing.

Parameters:

rightLinePaint - right Line Paint.

setLeftLinePaint

public void setLeftLinePaint(java.awt.Paint leftLinePaint)

Sets the paint for the left line drawing.

Parameters:

leftLinePaint - left Line Paint.

setDelayRate

public void setDelayRate(int t)

Sets the delay rate for the timer for the animation. param t int delay rate.

setAnimatingNode

public void setAnimatingNode(DrawingTree<P> animatingNode)

Set the node for drawing. This method should be called for each change in node.

Parameters:

node - node used for drawing within the panel.

setComponentShown

public void setComponentShown(boolean componentShown)

Sets whether the tree is shown or not.

Overrides:

setComponentShown in class DrawingJPanel

Parameters:

componentShown - boolean flag as to whether the tree is shown.

drawLines

public void drawLines(java.awt.Graphics2D g2)

Draws the lines in the given panel using the Graphics2D.

Parameters:

g2 - Graphics2D to draw the lines within.

paintComponent

public void paintComponent(java.awt.Graphics g)

Overides paintComponenet and is called whenever the Panel needs to be painted. The painting includes painting the image and then painting the animation (if any).

Overrides:

paintComponent in class DrawingJPanel

Parameters:

g - Graphics to which the component is drawn.

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

Listens to action events.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Parameters:

e - ActionEvent that contains information about the tree.
