Fileupload

public class Fileupload
extends Button

A fileupload dialog used to let user upload a file.

There are two ways to use Fileupload:

1. Open as a modal dialog:

You don't create Fileupload directly. Rather, use get() or get(String, String).

5.0.2: If the event thread is disabled, an onUpload event (UploadEvent) is posted to all root components when the upload dialog is closed. If you want the event being sent to a particular component, specify the component in the desktop's attribute called org.zkoss.zul.Fileupload.target. For example,

desktop.setAttribute("org.zkoss.zul.Fileupload.target", mainWindow);
Fileupload.get();

2. Embed as part of the page:

You can create it as a component and then listen to the onUpload event (UploadEvent).

A non-XUL extension.
