org.zkoss.zul
Interface CustomConstraint

public interface CustomConstraint

Additional interface implemented with Constraint to denote a constraint supports a custom way to display the error message. If this interface is implemented, the default error box won't be displayed. Rather, showCustomError(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.WrongValueException) is called.

Note: if this interface is implemented, ClientConstraint is ignored, since all validation will be done at the server.
