public abstract class Screen
extends DynaGrid
implements EventSink, BindingTarget

Base class for all screens. It derives from DynaGrid, so the top-level layout of all screens is a grid. It also serves as a dispatcher for action events. If an action event is emitted by a component that is wired up to the screen class, this class will use the actionCommand as the name of a function in the deriving class to call. Such a function must have 1 argument, of type ActionEvent.

public final void validate()

Don't override in screen ! Weird effect - looses you hours !

Specified by:

validate in interface Component

Overrides:

validate in class Grid

public java.lang.Object[] saveHistoryState()

loadHistoryState

public void loadHistoryState(java.lang.Object[] savedState)

getHistoryTitle

public abstract java.lang.String getHistoryTitle()

isValid

public final boolean isValid()

Description copied from interface: PropertyComponent

Check if this component contains valid user input. In itself this operation will not mark the component in error. In order to apply error marking on invalid components you should use EchoSupport.doValidationRecursively(Component).

Specified by:

isValid in interface PropertyComponent

Overrides:

isValid in class DynaGrid

markInvalid

public final void markInvalid()

Description copied from interface: PropertyComponent

Marks the component as invalid. Typically puts a colored border around it to indicate the error.

Specified by:
