Examples of java.awt.Graphics.drawRect()

java.awt.Graphics.drawRect()
Draws the outline of the specified rectangle. The left and right edges of the rectangle are at x and x + width. The top and bottom edges are at y and y + height. The rectangle is drawn using the graphics context's current color. @param x the x coordinate of the rectangle to be drawn. @param y the y coordinate of the rectangle to be drawn. @param width the width of the rectangle to be drawn. @param height the height of the rectangle to be drawn. @see java.awt.Graphics#fillRect @see java.awt.Graphics#clearRect
