Class Ext.form.NumberField

This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager.

new Ext.FormPanel({
    height: 100,
    renderTo: Ext.getBody(),
    items: [{
        xtype: 'textfield',
        fieldLabel: 'Name'
    }]
});

How this component should be hidden. Supported values are "visibility" (css visibility), "offsets" (negative offset position) and "display" (css display) - defaults to "display".

For Containers which may be hidden and shown as part of a card layout Container such as a TabPanel, it is recommended that hideMode is configured as "offsets". This ensures that hidden Components still have height and width so that layout managers can perform measurements when calculating layouts.

This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager.

// Apply a style to the field's label:
<style>
    .required .x-form-item-label {font-weight:bold;color:red;}
</style>

    renderTo: Ext.getBody(),
    items: [{
        xtype: 'textfield',
        fieldLabel: 'Name',
        itemCls: 'required' //this label will be styled
    },{
        xtype: 'textfield',
        fieldLabel: 'Favorite Color'
    }]

See stateful for an explanation of saving and restoring Component state.

A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startup. The component must have either a stateId or id assigned for state to be managed. Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a component.

For state saving to work, the state manager's provider must have been set to an implementation of Ext.state.Provider which overrides the set and get methods to save and recall name/value pairs. A built-in implementation, Ext.state.CookieProvider is available.

To set the state provider for the current page:

Ext.state.Manager.setProvider(new Ext.state.CookieProvider());

Components attempt to save state when one of the events listed in the stateEvents configuration fires.

You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events
