Direct Known Subclasses:

IlvDHTMLImageButton

public class IlvImageButton
extends UICommand
implements IlvFacesComponent

This class defines a DHTML button that is represented by images depending on its state (normal, highlighted, selected).
This button can be a toggle button (and so have two selection states: selected and not selected) and be a part of a button group in which one button can be selected at a time.

Since:

JViews 6.0

Constructor Detail

IlvImageButton

public IlvImageButton()

Creates a new IlvImageButton instance.

Method Detail

createFacesComponent

public IlvFacesComponent createFacesComponent()

Creates the component that handles the implementation of the IlvFacesComponent interface. By default, it returns an IlvFacesComponentImpl instance.

Returns:

The component that handles the implementation of the IlvFacesComponent interface.

getAttributes

public Map getAttributes()

Return a mutable Map representing the attributes (and properties, see below) associated with this UIComponent, keyed by attribute name (which must be a String). The returned implementation must support all of the standard and optional Map methods, plus support the following additional requirements:

• The Map implementation must implement the java.io.Serializable interface.
• Any attempt to add a null key or value must throw a NullPointerException.
• Any attempt to add a key that is not a String must throw a ClassCastException.
• If the attribute name specified as a key matches a property of this UIComponent's implementation class, the following methods will have special behavior:
  • containsKey - Return false.
  • get() - If the property is readable, call the getter method and return the returned value (wrapping primitive values in their corresponding wrapper classes); otherwise throw IllegalArgumentException.
  • put() - If the property is writable, call the setter method to set the corresponding value (unwrapping primitive values in their corresponding wrapper classes). If the property is not writeable, or an attempt is made to set a property of primitive type to null, throw IllegalArgumentException.
  • remove - Throw IllegalArgumentException.

Overrides:

getAttributes in class UIComponentBase

Since:

JViews 8.1
