public interface Drawable

Interface providing functions for a lightweight component that can be drawn on the screen. Functions include management of the bounding rectangle, returning a preferred size for layout operations, or drawing using a specified context.

double	getHeight() Returns the height of the bounds.
java.awt.geom.Dimension2D	getPreferredSize() Returns the preferred size of the Drawable.
double	getWidth() Returns the width of the bounds.
double	getX() Returns the x-position of the bounds.
double	getY() Returns the y-position of the bounds.
void	setBounds(double x, double y, double width, double height) Sets the bounds to the specified coordinates, width and height.
void	setBounds(java.awt.geom.Rectangle2D bounds) Sets the bounds to the specified bounding rectangle.
void	setPosition(double x, double y) Sets the position to the specified coordinates.

Method Detail

getBounds

java.awt.geom.Rectangle2D getBounds()

Returns the bounds of this Drawable.

Returns:

a bounding rectangle

setBounds

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

Sets the bounds to the specified bounding rectangle.

Parameters:

bounds - rectangle containing the component.

setBounds

void setBounds(double x,
               double y,
               double width,
               double height)

Sets the bounds to the specified coordinates, width and height. This method should be used when overriding functionality.

Parameters:

x - horizontal position of the upper-left corner

y - vertical position of the upper-left corner

width - horizontal extent

height - vertical extent

getX

double getX()

Returns the x-position of the bounds.

Returns:

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

getY

double getY()

Returns the y-position of the bounds.

Returns:

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

setPosition

void setPosition(double x,
                 double y)

Sets the position to the specified coordinates.

Parameters:

x - Coordinate on the x-axis.

y - Coordinate on the y-axis.

getWidth

double getWidth()

Returns the width of the bounds.

Returns:

horizontal extent

getHeight

double getHeight()

Returns the height of the bounds.

Returns:

vertical extent

getPreferredSize

java.awt.geom.Dimension2D getPreferredSize()

Returns the preferred size of the Drawable.

Returns:

horizontal and vertical extent that wants to be reached

draw

void draw(DrawingContext context)

Draws the Drawable with the specified drawing context.

Parameters:

context - Environment used for drawing
