public class GraphRect

extends GraphUnit

GraphRect(int, int, Color)

Creates an Instance of Partial rectangle with its starting point the top left set along with the Color and type

GraphRect(int, int, int, int, Color)

Creates a Rectangle that is complete in all aspects of its definition although the rectangle arguments are start and end points of the user interaction, it appropriately identifies the left top and width and height

GraphRect(DataInputStream)

Creates an instance of the GraphRect by reading the data from the Input Stream.

addnext(int, int)

Add next assumes that the input is referred to as the final point of user description of the diagonal.

erase(Graphics, Color)

Rendering method that actually erases the Rect from the canvas/screen Called by the screen update thread.

isInside(int, int)

method to verify if the passed point is enclosed in the handles of this Object.

paint(Graphics)

Rendering method that actually draws the rectangle to the canvas/screen Called by the screen update thread.

  public GraphRect(int x1,
                   int y1,
                   Color arg)

Creates an Instance of Partial rectangle with its starting point the top left set along with the Color and type

Parameters:

x1 - the x coordinate of the starting point

y1 - the y coordinate of the starting point

arg - the color of this rectangle.

  public GraphRect(int x1,
                   int y1,
                   int x2,
                   int y2,
                   Color arg)

Creates a Rectangle that is complete in all aspects of its definition although the rectangle arguments are start and end points of the user interaction, it appropriately identifies the left top and width and height

Parameters:

x1 - the x coordinate of the starting point

y1 - the y coordinate of the starting point

x2 - the x coordinate of the end point

y2 - the y coordinate of the end point

arg - the color of this rectangle.

  public GraphRect(DataInputStream din) throws IOException

Creates an instance of the GraphRect by reading the data from the Input Stream. It then fills up the member variables of the class

Parameters:

din - DataInputStream the stream from which the data is read

Throws: IOException

if an I/O error occurs

  public void addnext(int x,
                      int y)

Add next assumes that the input is referred to as the final point of user description of the diagonal. Hence, it corrects the data in xmin, ymin such that xmin, ymin map to top left and xmax, ymax to width and height respectively.

Parameters:

x - int x-coordinate

y - int y-coordinate

Overrides:

addnext in class GraphUnit

  public void paint(Graphics g)

Rendering method that actually draws the rectangle to the canvas/screen Called by the screen update thread. Paints in PaintMode of Graphics

Parameters:

g - Graphics to which the object is rendered onto

Overrides:

paint in class GraphUnit

  public void erase(Graphics g,
                    Color arg)

Rendering method that actually erases the Rect from the canvas/screen Called by the screen update thread. Useful to provide rubber-banding paints in XOR mode of the graphics

Parameters:

g - Graphics to which the object is rendered onto

arg - Color of the background

Overrides:

erase in class GraphUnit

  public boolean isInside(int x,
                          int y)

method to verify if the passed point is enclosed in the handles of this Object.

Parameters:

x - x-coordinate of the point

y - y-coordinate of the point

Returns:

boolean true iff the point is enclosed in the handles

Overrides:

isInside in class GraphUnit
