Method Detail

addLayer

protected void addLayer(LayerPath path)

createLayer

protected abstract Layer createLayer()

isOn

public boolean isOn()

Specified by:

isOn in interface Feature

Overrides:

isOn in class AbstractFeature

isTwoState

public boolean isTwoState()

Description copied from interface: Feature

Indicates whether the feature can be either on or off, without any other states. This is used by the tool bar and menu-bar menus to determine whether the feature's enable/disable button or menu item should be displayed with an indicator that it's either on or off. In the case of a menu the indicator is a check box. In the case of a tool bar button the indicator is a dot above the button.

Specified by:

isTwoState in interface Feature

Overrides:

isTwoState in class AbstractFeature

Returns:

true if the feature has only two states, otherwise off.

removeLayer

protected void removeLayer()

turnOn

public void turnOn(boolean tf)

Specified by:

turnOn in interface Feature

Overrides:

turnOn in class AbstractFeature
