Selecting all items in a list

Question

I'm working on Java Swing List and I wanna select all its values or items with the use of jCheckBox. I tried searching some answer on google and I could hardly find any.

I hope I can get answers from here.

Thanks.

EDIT:

In my swing list, I have these items for example:

Item 1
Item 2
Item 3

and I have a checkbox label as 'Select All'.

So what I want is when my checkbox is selected/checked, All the items in the swing list will be selected at once.

hint: skim the api doc on how to select a range of items, then extrapolate to all ... — kleopatra, Oct 14 '13 at 22:59
Something like `JList#getSelectionModel#setSelectionInterval`? — MadProgrammer, Oct 14 '13 at 23:08

*"and I wanna select all its values.."* Do you want to spell expressions like 'want to' properly, or should I ignore you? — Andrew Thompson, Oct 15 '13 at 05:46

You want JList's

" void setSelectedIndices(int[] indices) Changes the selection to be the set of indices specified by the given array."

method. Don't forget to activate the property that allows multiselect Also remember to cancel stuff when the box is unchecked!

good luck

ehhh ... no, wrong method (you don't want to to create an array containing all indices ;-) – kleopatra Oct 15 '13 at 08:27

Create a setter and getter for list size. The getter will be the end point of setSelectionInterval(start, end);

JList list = new JList();
private void insertItem(){
DefaultListModel<String> list_model = new DefaultListModel<String>();
String listData[] = {"Fish", "Pork", "Chicken", "Curry"};
for(int i = 0; i < listData.length; i++)
list_model.addElement(listData[i]);
list.setModel(list_model); setListSize(list.size());
}

foodCb.addItemListener(new ItemListener() {
@Override
public void itemStateChanged(ItemEvent evt) {
if(evt.getStateChange() == ItemEvent.SELECTED)
list.setSelectionInterval(0, getListSize());
else
list.clearSelection();
}
});

int list_size = 0; private void setListSize(int size) { list_size = size; }

private void getListSize() { return list_size; }
