I have the below configuration for a textarea, while the vertical scrollbars appear as the text increases, the horizontal scrollbar does not appear as the length of a sentence increases. I do not want the word wrapping and want it to horizontally scroll. Searching documentation and forums did not help.

Code:
     {
            xtype: 'textarea',
            name: 'inputText',
            colspan: 3,
            height: 300,
            width: 400,
            allowBlank: false
        }
Is there something very common that I am missing here?
