- * @class Ext.form.field.File
- * @extends Ext.form.field.Text
-
-A file upload field which has custom styling and allows control over the button text and other
-features of {@link Ext.form.field.Text text fields} like {@link Ext.form.field.Text#emptyText empty text}.
-It uses a hidden file input element behind the scenes to allow user selection of a file and to
-perform the actual upload during {@link Ext.form.Basic#submit form submit}.
-
-Because there is no secure cross-browser way to programmatically set the value of a file input,
-the standard Field `setValue` method is not implemented. The `{@link #getValue}` method will return
-a value that is browser-dependent; some have just the file name, some have a full path, some use
-a fake path.
