ComboBox: keep the pull down?

Thread view:

Hello,
Is there a method to keep the pull down for a ComboBox, i.e., the user
does not have to click on the ComboBox in order to pull down the list?
Thanks.

Hello,

If I understand your question correctly, I would suggest you may want
to use a JList instead of a ComboBox. For more details, see:

http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/JList.html
and
http://java.sun.com/docs/books/tutorial/uiswing/components/list.html#selection

Carl.

you probably need JList.

see http://mindprod.com/jgloss/jlist.html. it is like a JComboxBox
that stays open. You can put it is a JScrollpane it if gets too big.

Hi Guys, thank you all very much. A user requested to have that
ComboBox open by default, but reduce it when he wants to. I guess it's
not doable. Looks like I have to either use a JList to keep it open all
the time, or keep the ComboBox and have the user click on it to open
the list.

Sorry, from your initial post I got the impression that you were not
aware of the JList component.

If you are sure you only want to modify the state of a JComboBox you
should have a look at the setPopupVisible(boolean) method of the
JComboBox.

Carl.
