Constructor Detail

Velocimeter

public Velocimeter()

Constructs a velocimeter using the default gauge and pointer images

Velocimeter

public Velocimeter(java.lang.String gaugeImagePath,
                   java.lang.String pointerImagePath)

Constructs a velocimeter using the given images. Note that the pointer should be all-white so it can be correctly colorized, and it must also be pointing to the gauge's position 0. Both images must be squared.

Method Detail

initUI

public void initUI()

Description copied from class: Container

Called to initialize the User Interface of this container. This differs from the onAddAgain method by that this method is called only once, at the first time the control is added to the parent. When the container is being setup, the initUI method is called; then, the onAddAgain is called every time the container is added again.

Overrides:

initUI in class Container

onPaint

public void onPaint(Graphics g)

Description copied from class: Container

Draws the border (if any). If you override this method, be sure to call super.onPaint(g);, or the border will not be drawn.

Overrides:

onPaint in class Container

Parameters:

g - the graphics object for drawing
