Constructor Detail

BusyPainter

public BusyPainter()

Creates new busy painter initialized to the shape of circle and bounds size 26x26 points.

BusyPainter

public BusyPainter(int height)

Creates new painter initialized to the shape of circle and bounds of square of specified height.

Parameters:

height - Painter height.

BusyPainter

public BusyPainter(Shape point,
                   Shape trajectory)

Initializes painter to the specified trajectory and and point shape. Bounds are dynamically calculated to so the specified trajectory fits in.

Parameters:

point - Point shape.

trajectory - Trajectory shape.

Method Detail

getScaledDefaultTrajectory
