JList

Modify the selected elements in a JList

Given a JList like

JList myList = new JList(items);

the selected items in the list can be modified through the ListSelectionModel of the JList:

ListSelectionModel sm = myList.getSelectionModel();  
sm.clearSelection();                      // clears the selection
sm.setSelectionInterval(index, index);    // Sets a selection interval
                                          // (single element, in this case)

Alternatively, JList also provides some convenient methods to directly manipulate the selected indexes:

myList.setSelectionIndex(index);            // sets one selected index
                                            // could be used to define the Default Selection

myList.setSelectedIndices(arrayOfIndexes);  // sets all indexes contained in
                                            // the array as selected
