Thanks,

I create a JComboBox and setEditable(true) and set initial item to zero (which
looks like a textfield).
The problem? 1st time when keys are typed and <enter> key is pressed, it fires
itemlistener.

Only on the first time.

How do I turn off the <enter> from firing an itemlistener at startup?

Hi,

Maybe you could remove the corresponding KeyStroke from JComboBox's InputMap
.

Regards,

Arnaud

I tried removing the keystroke from the inputmap and still consumes <enter> key

You say this happens only on the first time. What happens the next time
you modify the text then hit <enter>?

If you have registered an ItemListener on the JComboBox, it should be
invoked either twice every time you type the <enter> key after you
change the text: once to report that the original item was deselected,
and again to report that the new item has been selected.

If you turn somehow turn off <enter> from firing itemListeners, how will
your application know when you have finished entering a new value?

remove the itemlistener from the code like this..
combobox.removeItemListener() and you can again implement it when ever you
want..
