/**
- * @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.
-{@img Ext.form.File/Ext.form.File.png Ext.form.File component}
-#Example Usage:#
-
- Ext.create('Ext.form.Panel', {
- title: 'Upload a Photo',
- width: 400,
- bodyPadding: 10,
- frame: true,
- renderTo: Ext.getBody(),
