public interface LayoutData
extends java.io.Serializable
Component and its
parent Component. A LayoutData object may
contain layout, position, color, or other data to describe how a given
Component should be rendered within its parent.
LayoutData objects are used as values of the
layoutData property defined in the Component
class.
LayoutData is a marker interface which is implemented by all
objects providing such layout information. A component which needs to present
layout information to its parent should use the specific derivative of
LayoutData applicable to its parent component, e.g., a child
of a Grid might use the GridLayoutData
implementation. The specific LayoutData implementations
available for use with a given parent component will be described in the
parent component's documentation.
WARNING: Setting an incompatible LayoutData
property on a Component may result in a render-time exception
being thrown. Take care to check the requirements specified by the
documentation of a container Component before setting a
LayoutData on a child of that container.
