Class WOImage

java.lang.Object
  net.wotonomy.web.WOElement
      net.wotonomy.web.WODynamicElement
          net.wotonomy.web.WOImage

All Implemented Interfaces:

java.io.Serializable, WOActionResults

Direct Known Subclasses:

WOBody, WOImageButton

public class WOImage
extends WODynamicElement

WOImage renders a dynamically generated IMG tag. The URL for the image SRC can be static, or it can be generated dynamically to return a NSData object (with a mime-type) or even return the contents of a file (not implemented yet). Bindings are:

• src: A static URL for the image source.
• data: A NSData object with the image content. Must be used with mimeType.
• mimeType: The MIME type for the image data. Can be used with filename or data bindings.
• filename: The path to a file containing an image.
• framework: The optional framework from whence the image should be retrieved (used in conjunction with filename).

Description copied from class: WODynamicElement

This method is called on all elements of the content tree to build a response to a user request. The message should be forwarded to any child elements so that the entire tree is traversed. This implementation does nothing.

Overrides:

appendToResponse in class WODynamicElement

invokeAction

public WOActionResults invokeAction(WORequest r,
                                    WOContext c)

Description copied from class: WODynamicElement

This method is called on all objects and elements of the application until a non-null value is returned. WOElements should first check to see if they are the target of an action by checking the WOContext's senderID to see if it matches this element's elementID. If this element is the target, it should perform an appropriate action on the context's current WOComponent, usually the action specified in the binding, and return the result of that action. This implementation returns null.

Overrides:

invokeAction in class WODynamicElement
