Java JLabel - add a unique identifier

问题

Is there anyway to add an ID or a unique identifier to a JLabel?

Thanks all

回答1:

JLabel has a setName method that is inherited from java.awt.Component. You could use this for an ID.

回答2:

You can call Component.setName on it, or JComponent.putClientProperty, or subclass or use the JLabel object as a key is a Map of some sort.

But probably the way to go is to keep hold of a reference to the original object, so you can write clean, direct code that doesn't have to look the component up.
