Hello,

I am trying to disable the JTextField 'textfield' when the JComboBox is set to 'item2'. When the combo box is set to 'item1' I want the JTextField to be enabled.

Also is there a way where I can highlight the borders of the JComboBox to yellow when the user hovers over them?

Below is the code.

Thanks
