JList returns

[moxy]

Can anyone please enlighten me as to what a JList returns? If I have a list of 10 items and the user selects 3, do I need a listListener to capture that information and is there a way to limit selections to three instead of the MULTIPLE_INTERVAL_SELECTION?

Thanks.

That depends on the method you use.

// To get all selections use:

Object [] ob=aList.getSelectedValues();

// then typecast to what you know is in the list

MyClass mC=(MyClass)ob[0];

//to limit this to three use:

if (ob.length > 3) {
  /* signal error: "can  select max  three" */
}

//to set selection limits

aList.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);

PS: still that blank insert in the code tag
its: SINGLE_INTERVAL_SELECTION
