When I click a Jlist which is inside a JScrollPane, I want the selection to be copied to a JTextArea. Problem is, it copies twice every time! It seems it copies once for mouse press and once for mouse release. I thought the ActionListener would just see the mouse click event. Anybody any ideas?
I have already added the ListSelectionListener - see code snippets below:
locationList.addListSelectionListener(this);
public void valueChanged(ListSelectionEvent event)
{
JList source = (JList)event.getSource();
String aselection = "";
if(source == locationList)
{
bookDetails.append("Now enter a Bay No...");
aselection = (String)locationList.getSelectedValue();
aplace = new Location();
aplace.setArea(aselection);
bookDetails.append(aplace.getArea() + "\n");
}
}// End of valueChanged method
The text area is bookDetails and the append method appends the text on to the text area - but it appends it twice - even for one mouse click. Even if I put the append method outside the if statement, it still goes in twice.
The othe way is to use the mouse listener, this will print on dubleclick,
jlist.addMouseListener(new MouseAdapter()
{public void mousePressed(MouseEvent m)
{
if (m.getClickCount() == 2)
{
int index = jlist.locationToIndex(m.getPoint());
System.out.println("Double clicked on Item " + index);
}
}
});
