/**
 * TActiveFileUpload
 *
 * TActiveFileUpload displays a file upload field on a page. Upon postback,
 * the text entered into the field will be treated as the name of the file
 * that will be uploaded to the server. The property {@link getHasFile HasFile}
 * indicates whether the file upload is successful. If successful, the file
 * may be obtained by calling {@link saveAs} to save it at a specified place.
 * You can use {@link getFileName FileName}, {@link getFileType FileType},
 * {@link getFileSize FileSize} to get the original client-side file name,
 * the file mime type, and the file size information. If the upload is not
 * successful, {@link getErrorCode ErrorCode} contains the error code
 * describing the cause of failure.
 *
 * TActiveFileUpload raises {@link onFileUpload OnFileUpload} event if a file is uploaded
 * (whether it succeeds or not).
 *
 * TActiveFileUpload actually does a postback in a hidden IFrame, and then does a callback.
 * This callback then raises the {@link onFileUpload OnFileUpload} event. After the postback
 * a status icon is displayed; either a green checkmark if the upload is successful,
 * or a red x if there was an error.
