JPolygonFlash

public JPolygonFlash(javax.swing.JPanel p,
                     CPolygon poly1,
                     CPolygon poly2,
                     boolean oc,
                     double xc,
                     double yc,
                     int c1,
                     int c2,
                     int tt)

Constructs a new JPolygonFlash with the specified parameters.

Parameters:

p - the JPanel to associate with this JPolygonFlash

poly1 - the first CPolygon to be used in the flashing effect

poly2 - the second CPolygon to be used in the flashing effect

oc - a boolean indicating whether to use the specified center coordinates

xc - the x-coordinate of the center

yc - the y-coordinate of the center

c1 - the first color index for the flashing effect

c2 - the second color index for the flashing effect

tt - the type of flashing effect

Method Detail

getCentroidX

public double getCentroidX(java.util.Vector v)

Calculates the x-coordinate of the centroid of the given vector of points.

Parameters:

v - the vector of points

Returns:

the x-coordinate of the centroid

getCentroidY

public double getCentroidY(java.util.Vector v)

Calculates the y-coordinate of the centroid of the given vector of points.

Parameters:

v - the vector of points

Returns:

the y-coordinate of the centroid

actionPerformed

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

Handles the action event for the timer, updating the animation state and repainting the panel.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Parameters:

e - the action event

stop

public void stop()

Stops the flashing effect and makes the second polygon visible.

Overrides:

stop in class JFlash

start

public void start()

Starts the flashing effect and makes the second polygon invisible.

Overrides:

start in class JFlash

recalculate

public void recalculate()

Recalculates the flashing effect by reinitializing the animation state.

Overrides:

recalculate in class JFlash

draw

public boolean draw(java.awt.Graphics2D g2)

Draws the flashing polygon effect based on the current animation state.

This method computes the polygon's vertex positions by either applying a rotation and translation transformation or by linearly interpolating between two sets of points, depending on the current flashing type. It then fills the polygon with an interpolated color and draws its outline.

The method returns false if the animation is not running or has finished.

Specified by:

draw in class JFlash

Parameters:

g2 - the Graphics2D context used for drawing

Returns:

true if the polygon is successfully drawn; false otherwise
