Name  

redraw()

   
Examples   
float x = 0; 
 
void setup() { 
  size(200, 200); 
  noLoop(); 
} 
 
void draw() { 
  background(204); 
  line(x, 0, x, height); 
} 
 
void mousePressed() { 
  x += 1; 
  redraw(); 
}

Description   Executes the code within draw() one time. This functions allows the program to update the display window only when necessary, for example when an event registered by mousePressed() or keyPressed() occurs. In structuring a program, it only makes sense to call redraw() within events such as mousePressed(). Calling it within draw() has no effect because draw() is continuously called anyway.
