Constructor Detail

Polygon

public Polygon(int x1,
               int y1,
               int... points)

Creates a polygon with the given vertices. This constructor takes a variable number of arguments to allow polygons to be created with arbitrariily many vertices. For example, calling the constructor with the parameters (x1, y1, x2, y2, x3, y3, x4, y4) would create a polygon with 4 sides. By default, the polygon is black.

Parameters:

x1 - the x coordinate of the first end point

y1 - the y coordinate of the first end point

points - the remaining coordinates x2, y2, x3, y3, etc.

Method Detail

isFilled

public boolean isFilled()

Description copied from class: Graphic

I If a Graphic is filled, it will be painted in a solid color.

Overrides:

isFilled in class Graphic

Returns:

true if the Graphic is filled.

setFilled

public void setFilled(boolean filled)

Description copied from class: Graphic

Sets whether or not the graphic should be filled (painted in a solid color). A Graphic will ignore this method if its filled status cannot be changed.

Overrides:

setFilled in class Graphic

Parameters:

filled - whether or not the Graphic should be filled

contains

public boolean contains(int x,
                        int y)

This contains method reports true if the given point is contained within the polygon..

Overrides:

contains in class javax.swing.JComponent

Parameters:

x - the x coordinate of the point

y - the y coordinate of the point

paint

public void paint(java.awt.Graphics g)

Paints the Line when requested by the Java's graphics system. You should not need to call this method. If you want to specifically request that a component be repainted, call Component.repaint(). (If you do not see the polygon, it may not have been added to a visible container, it may be behind another graphic, its color may blend with the background, or its coordinates may be outside the visible region of the container.)

Overrides:

paint in class javax.swing.JComponent

toString

public java.lang.String toString()

Returns a String representation of the polygon.

Overrides:

toString in class Graphic

Returns:

a String description of this graphic, including its class name, upper left corner, and pixel dimensions.
