Combo box selection

[Cathy Song]

Hi Ranchers,

I was wondering if it is possible to select more than one items in a combo box (using ctrl key).

Thanks,
Cathy.

JComboBoxes are single selection. For multiple selection, use a JList

Thank for your reply David.

Instead of having to scroll, can I make the list have a pull down feature like
combo box. I want a component that would be pull down and allow multiple selection. Will I need to create a custom component?

Thanks,
Cathy.

It sounds like you want to use a JComboBox to trigger a little popup screen. This is done with the ComboPopup interface:
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/plaf/basic/ComboPopup.html

A good example of this in use is the DateComboBox:
here is the code to that:

if you load that and run it, you can imagine your list component in the popup instead of their date component.
