Field Details

clickMode

protected int clickMode

What to do on click? 0 means sequence through aspects; 1 means alternate the "lit" aspect; 2 means alternate the "held" aspect.

litMode

protected boolean litMode

How to handle lit vs not lit?

False means ignore (always show R/Y/G/etc appearance on screen); True means show "dark" if lit is set false.

Note that setting the appearance "DARK" explicitly will show the dark icon regardless of how this is set.

SignalHeadIcon

public SignalHeadIcon(Editor editor)

Method Details

deepClone

public Positionable deepClone()

Description copied from interface: Positionable

Make a deep copy of Positional object. Implementation should create a new object and immediately pass the object to finishClone() returning the result of finishClone(). i.e. implementation must be:

public Positionable deepClone() { Subtype t = new Subtype(); return finishClone(t); }

Then finishClone() finishes the deep Copy of a Positional object. Implementation should make deep copies of the additional members of this sub class and then pass Positionable p to super.finishClone(). i.e. implementation must terminate with statement return super.finishClone(p); See IndicatorTurnoutIcon extends TurnoutIcon extends PositionableLabel for an example of how to continue deep cloning a chain of subclasses.

Specified by:

deepClone in interface Positionable

Overrides:

deepClone in class PositionableIcon

Returns:

the copy

finishClone

protected Positionable finishClone(SignalHeadIcon pos)

setSignalHead

public void setSignalHead(NamedBeanHandle<SignalHead> sh)

Attach a SignalHead element to this display item by bean.

Parameters:

setSignalHead

public void setSignalHead(String pName)

Attach a SignalHead element to this display item by name. Taken from the Layout Editor.

Parameters:

pName - Used as a system/user name to lookup the SignalHead object
