jtable mouse click behaviour

[miguel lisboa]

i'm experimenting and at a given point i'v this code:

    ListSelectionModel rowSM = jTable.getSelectionModel();
    
    rowSM.addListSelectionListener(new ListSelectionListener() {
    
    public void valueChanged(ListSelectionEvent e) {    
    
    ListSelectionModel lsm = (ListSelectionModel)e.getSource();
 
    int selectedRow = lsm.getMinSelectionIndex();
    
    for (int i = 0; i < colunas.length; i++) {
    
    System.out.println("valores " + jTable.getValueAt(selectedRow, i));
 
    }
 
    }
    
    });    

i notice output appears twice: on mouse down once, and again on mouse up
should this act this way?

Yes.
A ListSelectionListener is most interested in tracking all changes in list
selections: de-selection and selection. If you want to wait until all the
flurry of activity subsides before asking what the new selection is you
can use the ListSelectionEvent method getValueIsAdjusting.

public void valueChanged(ListSelectionEvent e) {
    if(!e.getValueIsAdjusting()) {
         // all is quiet, okay to ask for the new selection state
    }
}
