</span> * A basic hidden field for storing hidden values in forms that need to be passed in the form submit.
*
* This creates an actual input element with type="submit" in the DOM. While its label is
* {@link #hideLabel not rendered} by default, it is still a real component and may be sized according
* to its owner container's layout.
*
* Because of this, in most cases it is more convenient and less problematic to simply
* {@link Ext.form.action.Action#params pass hidden parameters} directly when
* {@link Ext.form.Basic#submit submitting the form}.
*
* Example:
*
* new Ext.form.Panel({
* title: 'My Form',
* items: [{
* xtype: 'textfield',
* fieldLabel: 'Text Field',
* name: 'text_field',
* value: 'value from text field'
* }, {
* xtype: 'hiddenfield',
* name: 'hidden_field_1',
* value: 'value from hidden field'
* }],
*
* buttons: [{
* text: 'Submit',
* handler: function() {
* this.up('form').getForm().submit({
* params: {
* hidden_field_2: 'value from submit call'
* }
* });
* }
* }]
* });
*
* Submitting the above form will result in three values sent to the server:
*
* text_field=value+from+text+field&hidden;_field_1=value+from+hidden+field&hidden_field_2=value+from+submit+call
*
