Constructor Summary

BooleanWidget()
If you use this constructor, you are very much on your own and are responsible for setting up all the things the Widget needs to operate yourself.

BooleanWidget(java.lang.String name)
you can initialise a BooleanWidget with just a name...

BooleanWidget(java.lang.String name, java.lang.String prompt)
name and prompt is better

BooleanWidget(java.lang.String name, java.lang.String prompt, java.lang.String help)
name, prompt and helptext is better still.

Method Summary

void	layout(Context context, int tabIndex) layout just the widget, without prompt, help, or surrounding context, coercing it to this type
protected void	preProcess(Context context) If anything at all comes back in my name, then I'm true; otherwise, I'm false
