Method Detail

setPushedSkin

public void setPushedSkin(ej.fp.Image pushedSkin)

Sets the skin to show the wheel press event.

This method should only be called by front panel parser.

Parameters:

pushedSkin - the press skin.

setMaxAngle

public void setMaxAngle(double maxAngle)

Sets the bigger angle the wheel can have. A zero-angle means infinite.

This method should only be called by front panel parser.

Parameters:

maxAngle - an angle in degree.

setSteps

public void setSteps(ej.fp.Image[] steps)

Sets the images which simulate the wheel rotation. The number of images is not defined but first image is for the wheel state 0° and the last image for the wheel state max°.

This method should only be called by front panel parser.

Parameters:

steps - array of images.

setListenerClass

public void setListenerClass(java.lang.String listenerClassName)

Defines the user class which has to implement Wheel.WheelListener.

This method should only be called by front panel parser.

Parameters:

listenerClassName - user listener class name.

finalizeConfiguration

public void finalizeConfiguration()

Overrides:

finalizeConfiguration in class ej.fp.Widget

start

public void start()

Overrides:

start in class ej.fp.Widget

newDefaultListener

protected java.lang.Object newDefaultListener()

Description copied from class: WidgetWithListener

Lets subclass creates a default listener. This method must not return null. The listener should at least prints some traces in the standard output stream.

Overrides:

newDefaultListener in class WidgetWithListener

Returns:

a default listener.

mousePressed

public void mousePressed(int x,
                         int y,
                         ej.fp.MouseListener.MouseButton button)

Specified by:

mousePressed in interface ej.fp.MouseListener

mouseDragged

public void mouseDragged(int x,
                         int y)

Specified by:

mouseDragged in interface ej.fp.MouseListener

mouseReleased

public void mouseReleased(int x,
                          int y,
                          ej.fp.MouseListener.MouseButton button)

Specified by:

mouseReleased in interface ej.fp.MouseListener

dispose

public void dispose()

Overrides:

dispose in class ej.fp.Widget
