public final class Polygon

extends QTHandleRef

implements QuickTimeLib, java.lang.Cloneable

The Polygon represents an arbitary area or set of areas on the drawing coordinate plane. Methods are implemented for a corresponding QuickDraw structure used by QuickTime. refer to Polygon in QuickDraw

Constructor Detail

Polygon

public Polygon(QDGraphics g)
        throws QTException

Allocates a new empty Polygon.

QuickDraw::OpenPoly

Method Detail

close

public void close()
           throws QDException

Completes the collection of lines that define the polygon.

QuickDraw::ClosePoly

QDException

getSize

public int getSize()

Returns size of the Polygon.

Overrides:

getSize in class QTHandleRef

Returns:

the size of the handle

getPolyBBox

public QDRect getPolyBBox()

Returns a copy of the bounding rectangle of the Polygon.

Returns:

a rect

getBounds

public QDRect getBounds()

Returns a copy of the bounding rectangle of the Polygon.

Returns:

a rect

copy

public Polygon copy()
             throws QTException

Copies the mathematical structure of the implicit Polygon into a newly created Polygon.

Returns:

A new Polygon copy.

QTException

clone

public java.lang.Object clone()

Copies the mathematical structure of the implicit Polygon into a newly created Polygon.

QuickDraw::Copy

Overrides:

clone in class java.lang.Object

Returns:

A new Polygon copy.

toString

public java.lang.String toString()

Print information about this object.

Overrides:

toString in class QTHandleRef

Returns:

a string representing this Polygon object

offset

public void offset(int dh,
                   int dv)
            throws QDException

offset moves the Polygon by adding the value you specify in the dh parameter to the horizontal coordinates of its points, and by adding the value you specify in the dv parameter to the vertical coordinates of all points of its boundary. If the values of dh and dv are positive, the movement is to the right and down; if either is negative, the corresponding movement is in the opposite direction. The Polygon retains its size and shape. This doesnŐt affect the screen unless you subsequently redraw the polygon.

QuickDraw::OffsetPoly()

Parameters:

dh - The horizontal distance to move the polygon.

dv - The vertical distance to move the polygon.

QDException
