List of clearRect() Examples

Examples of clearRect()

ae.java.awt.Graphics.clearRect()
Clears the specified rectangle by filling it with the background color of the current drawing surface. This operation does not use the current paint mode.
Beginning with Java 1.1, the background color of offscreen images may be system dependent. Applications should use setColor followed by fillRect to ensure that an offscreen image is cleared to a specific color. @param x the x coordinate of the rectangle to clear. @param y the y coordinate of the rectangle to clear. @param width the width of the rectangle to clear. @param height the height of the rectangle to clear. @see ae.java.awt.Graphics#fillRect(int,int,int,int) @see ae.java.awt.Graphics#drawRect @see ae.java.awt.Graphics#setColor(ae.java.awt.Color) @see ae.java.awt.Graphics#setPaintMode @see ae.java.awt.Graphics#setXORMode(ae.java.awt.Color)
