Description akobberup 2012-02-02 09:11:51 UTC 
If i in a method in a new java class write the folowing code:

javax.swing.JButton cButton = new javax.swing.JButton();
cButton.addActionListener( this );

I will naturally get an error, like this:

method addActionListener in class javax.swing.AbstractButton cannot be applied to given types;
  required: java.awt.event.ActionListener
  found: <classname>
  reason: actual argument <classname> cannot be converted to java.awt.event.ActionListener by method invocation conversion

I would be nice to have a hint like 'Implement Interface' that will make my class implement the given interface - or extend the given arg. class if that is the case.

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,

I still find that this would make sense in nb 8.2
