Interface IStylePropertyChanges

All Known Implementing Classes:

ChangesRecorder

public interface IStylePropertyChanges

Components which wants to update themselfs with an ajax call should implement this interface.

It has a setChanged() method for marking the component for render. when calling setChanged() on it the component will be re rendered the next time a (ajax) request comes in This can be the ajax polling behavior that every page of a servoy application has if ajax mode is enabled.

When setChanged() is called you have to call setRendered() when the component is rendered again else it will be re rendered for every coming request. This can be done by calling setRendered() from the Component.onAfterRender() that the wicket component needs to override.

NOTE: Try to use the the implementation class ChangesRecorder this interface can change with new Servoy versions if new functionality is needed.
