Method Detail

getBounds

public java.awt.geom.Rectangle2D getBounds()

Returns the bounds of this Drawable.

Specified by:

getBounds in interface Drawable

Returns:

a bounding rectangle

getX

public double getX()

Returns the x-position of the bounds.

Specified by:

getX in interface Drawable

Returns:

horizontal position of the upper-left corner of the bounding rectangle.

getY

public double getY()

Returns the y-position of the bounds.

Specified by:

getY in interface Drawable

Returns:

vertical position of the upper-left corner of the bounding rectangle.

getWidth

public double getWidth()

Returns the width of the bounds.

Specified by:

getWidth in interface Drawable

Returns:

horizontal extent.

getHeight

public double getHeight()

Returns the height of the bounds.

vertical extent.

setBounds

public void setBounds(java.awt.geom.Rectangle2D bounds)

Sets the bounds to the specified bounding rectangle.

Specified by:

setBounds in interface Drawable

Parameters:

bounds - rectangle containing the component.

setBounds

public void setBounds(double x,
                      double y,
