Enclosing class:

Field2DDisplay

public class Field2DDisplay.MouseCoordinateReader

extends java.awt.event.MouseAdapter

implements java.awt.event.MouseMotionListener

an inner class, which reads the coordinates of the mouse and transforms them to complex coordinates. Also used for determining the gradient within a given radius

Constructor Summary

Field2DDisplay.MouseCoordinateReader()

Method Summary

void	mouseDragged(java.awt.event.MouseEvent e) paints a circle with radius of the current distance from circleCenter (set in mousePressed())
void	mouseMoved(java.awt.event.MouseEvent e)
void	mousePressed(java.awt.event.MouseEvent e) this method reads out the mouse coordinates, which are used by mouseDragged to put a circle around it, in order to calculate the gradient
void	mouseReleased(java.awt.event.MouseEvent e) calculates the gradient for the circle determined by mousePressed and mouseDragged
