Method Detail

register

public static void register()

Registers the Component with its peer bindings

clientAction

public void clientAction(java.lang.String action)

Description copied from interface: ClientActionProducer

Called when the user causes an action from the client.

Specified by:

clientAction in interface ClientActionProducer

Parameters:

action - The action command generated by the client.

See Also:

ClientActionProducer.clientAction(java.lang.String)

clientInput

public void clientInput(java.lang.String input)

Description copied from interface: ClientInputProducer

Called when a client sends an input string through an input field.

Specified by:

clientInput in interface ClientInputProducer

Parameters:

input - The data in the hidden input field in the controller form as last known.

See Also:

ClientInputProducer.clientInput(java.lang.String)

imageUpdate

public void imageUpdate(ImageUpdateEvent e)

Description copied from class: EchoPointComponentPeer

If an image changes, we redraw() the peer.

In 99% of cases, this is actually what you want to do.

Specified by:

imageUpdate in interface ImageUpdateListener

Overrides:

imageUpdate in class EchoPointComponentPeer

Parameters:

e - The event describing the image update.

See Also:

ImageUpdateListener.imageUpdate(nextapp.echo.event.ImageUpdateEvent)

render

public void render(RenderingContext rc,
                   Element parent)

Renders the Component

Specified by:

render in interface ComponentPeer

Overrides:

render in class AbstractComponentPeer

Parameters:

rc - A rendering context provided by the Connection.

parent - The element that will contain content rendered by this ComponentPeer.

renderCS

public void renderCS(RenderingContext rc,
                     Element parent)

Renders the Tree as a client side Tree

renderSS

public void renderSS(RenderingContext rc,
                     Element parent)

Renders the Tree as a server side Tree

unregistered

public void unregistered()

Description copied from class: EchoPointComponentPeer

This removes the property change listener and then calls toolTipHelper.unregistered();. If there is an ImageManager, then all images are removed.

Specified by:

unregistered in interface ComponentPeer

Overrides:

unregistered in class EchoPointComponentPeer

EchoPointComponentPeer.unregistered()
