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(java.awt.Shape point,
                   java.awt.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

isPaintCentered

public boolean isPaintCentered()

Gets value of centering hint. If true, shape will be positioned in the center of painted area.

Returns:

Whether shape will be centered over painting area or not.

setPaintCentered

public void setPaintCentered(boolean paintCentered)

Centers shape in the area covered by the painter.

Parameters:

paintCentered - Centering hint.

getXY

public static java.awt.geom.Point2D.Float getXY(float t,
                                                java.awt.geom.Point2D.Float begin,
                                                java.awt.geom.Point2D.Float ctrl,
                                                java.awt.geom.Point2D.Float end)

Calculates relative position of the point on the quad curve in time t<0,1>.

Parameters:
