I've created Ext.Window with some Ext.form fields inside. But when I resize window form elements still have initial width and height.

Is it required explicitly resize form fields on window resize? Or there is some option that enables auto resize of form fields?

Sample code:

var f_1 = new Ext.form.TextField({fieldLabel: 'Label 1'});

var f_2 = new Ext.form.TextField({fieldLabel: 'Label 2'});

var fp = new Ext.form.FormPanel({items: [f_1, f_2]});



var w = new Ext.Window({

    layout: 'form',

    title: 'test',

    items: fp

});



w.show()
