EXTJS4: how can i set the fieldlabel Width of a xtype:'textfield'

Question

I have a xytpe form, and i want so set the width of the fieldLabel and not the width of the label itself.

{
    xtype: 'textfield',
    id: 'iln',
    name: 'iln',
    fieldLabel: 'Product-Number-Field-with-body-height',
    allowBlank: true,
    anchor: '100%'
}

I tried everything...its only changes the textfield, and not the width of the fieldlabel. Any help? THANK YOU!

Solution

Changing the labelWidth is changing the input field's width because you are using anchor: 100%. Take this out and labelWidth should do more like you are expecting.
