Interface CVetoFocusListener

public interface CVetoFocusListener

This listener is used to prevent a CDockable from loosing or gaining the focus. Events may happen such that the framework is unable to prevent the focus from changing, e.g. if a CDockable is closed.
Please use this listener with care, the workflow of the user may be seriously hindered if the focus cannot be changed.
