+/**
+ * TFileUpload class
+ *
+ * TFileUpload 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}, {@link getFileType}, {@link getFileSize}
+ * 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.
+ *
+ * TFileUpload raises {@link onFileUpload FileUpload} event if a file is uploaded
+ * (whether it succeeds or not).
