public abstract class Widget

extends AbstractConfigurable

A general-purpose configurable GUI container Widgets are Configurable objects that represent AWT components. Adding a Widget to another Widget during a Buildable.build(org.w3c.dom.Element) operation will add the corresponding AWT component of the child to the component of the parent

Method Detail

build

public void build(org.w3c.dom.Element el)

For memory efficiency reasons, a Widget is initialized lazily. This method only stores the element from which the build the Widget. The Widget is built from the stored element by invoking rebuild(). Subclasses should invoke rebuild() before invoking getComponent()

Overrides:

build in class AbstractBuildable

Following copied from interface: VASSAL.build.Buildable

Parameters:

e - the XML element containing the object data

rebuild

protected void rebuild()

Perform the build of this Buildable component using the element stored from when the the build(org.w3c.dom.Element) method was invoked

getBuildElement

public org.w3c.dom.Element getBuildElement(org.w3c.dom.Document doc)

Overrides:

getBuildElement in class AbstractBuildable

Following copied from interface: VASSAL.build.Buildable

Returns:

an XML element from which this component can be built

getAllowableConfigureComponents

public java.lang.Class[] getAllowableConfigureComponents()

The allowable Configurable components of a Widget are the same as its parent

addTo

public void addTo(Buildable b)

Description copied from interface: Buildable

Adds this component to its parent. In order to make Buildable objects extensible, the child is reponsible for adding itself to the parent. That way, Buildable subcomponents can be defined in an extension package without needing to modify the containing class.

removeFrom

public void removeFrom(Buildable b)

Description copied from interface: Configurable

Remove this component from its parent

getParent

public Widget getParent()

getConfigureComponents

public Configurable[] getConfigureComponents()

Overrides:

getConfigureComponents in class AbstractConfigurable

Following copied from interface: VASSAL.build.Configurable

Returns:

an array of Configurer objects representing the Configurable children of this Configurable object

getComponent

public abstract java.awt.Component getComponent()

Returns:

the Component for this widget. For efficiency, the Component may be initialized lazily instead of being created in the Buildable.build(org.w3c.dom.Element) method

getHelpFile

public HelpFile getHelpFile()

Following copied from interface: VASSAL.build.Configurable

Returns:

a HelpFilte describing how to use and configure this component
