Question

I have a Java class with JList and ListSelectionListener:

final JList myList = new JList();

// ...

myList.addListSelectionListener(new ListSelectionListener() {
            public void valueChanged(ListSelectionEvent e) {  
                System.out.println("selected");
            }
});

but conclusion

selected
selected

How can I change my code, this output should be one selected?

Answer 1

Try

         if(e.getValueIsAdjusting())
      {
          System.out.println("Selected");  
      }

Answer 2

Take a look at getValueIsAdjusting .

Returns whether this is one of a series of several events where changes are still being made

Only print "selected" when this method returns false.

getValueIsAdjusting() ListSelectionEvent. API: , , .
