Setting the Selected Items in a JList Component
List selection events are fired when the following methods are used to
change the set of selected items (see
Creating a JList Component).
// Create a list and get the model
String[] items = {"A", "B", "C", "D"};
JList list = new JList(items);
// Select the second item
int start = 1;
int end = 1;
list.setSelectionInterval(start, end); // B
// Select the first 3 items
start = 0;
end = 2;
list.setSelectionInterval(start, end); // A, B, C
// Select all the items
start = 0;
end = list.getModel().getSize()-1;
if (end >= 0) {
list.setSelectionInterval(start, end); // A, B, C, D
}
// Clear all selections
list.clearSelection();
// Select the first item
start = 0;
end = 0;
list.setSelectionInterval(start, end); // A
// Add another selection - the third item
start = 2;
end = 2;
list.addSelectionInterval(start, end); // A, C
// Deselect the first item
start = 0;
end = 0;
list.removeSelectionInterval(start, end); // C
// Select a single item
boolean scrollIntoView = true;
list.setSelectedValue("B", scrollIntoView); // B
