public abstract void copyArea( int x,
int y,
int width,
int height,
int dx,
int dy )
Parameters
- x
- the x coordinate of the source rectangle.
- y
- the y coordinate of the source rectangle.
- width
- the width of the source rectangle.
- height
- the height of the source rectangle.
- dx
- the horizontal distance to copy the pixels.
- dy
- the vertical distance to copy the pixels.
Description
Copies an area of the component by a distance specified by
dx and dy. From the point specified
by x and y, this method
copies downwards and to the right. To copy an area of the
component to the left or upwards, specify a negative value for
dx or dy.
If a portion of the source rectangle lies outside the bounds
of the component, or is obscured by another window or component,
copyArea will be unable to copy the associated
pixels. The area that is omitted can be refreshed by calling
the component's paint method.
