BasicUploadField

public abstract class AbstractUploadField<T extends UploadReceiver>
extends com.vaadin.ui.CustomField<T>
implements com.vaadin.ui.Upload.StartedListener, com.vaadin.ui.Upload.FinishedListener, com.vaadin.ui.Upload.ProgressListener, com.vaadin.ui.Upload.FailedListener, com.vaadin.event.dd.DropHandler, UploadField

Main implementation of the UploadFile field. This implementation used some features of UploadField and associated classes.

This class handles Upload events and expose functions that allows to customize the 3 main upload states (link to a view Component):

• Empty: Display the initial view (No Upload was performed)
• InProgress: Display the progress view (Progress Bar)
  This view is triggered by a Upload.StartedEvent.
• Completed: Display the File detail and Icon
  This event is triggered by
  Upload.FinishedEvent
Upload.FailedEvent

Important exposed method
Upload getUpload() : Return the Vaadin Upload Component responsible for the Uploading a File based on a folder.
createDropZone(Component c) : Give the Drop ability to the passed Component.
