Trigger ExtJS input file event when dialogue window is closed

How can we capture the event when a file is selected in an open dialogue box and the OK button is clicked in extjs? **Off topic, the field does not stretch from its normal width.

        xtype: 'textfield',
        fieldLabel: 'New (JPG or PNG only)',
        labelSeparator: '',
        name: 'newPic',
        id:'newPic',
        anchor:'100%',
        inputType: 'file',
        allowBlank: false,

When I click the browse button, the open dialogue box appears. I need to retrieve the filename when I click the open button on the dialogue box.

Any suggestions would be greatly appreciated.

Thank you.
