I have a jcombobox with multiple entries. I want to filter the list as the user starts typing. How is it possible to hide entries in the jcombobox upon keyboard event?

Use regex to filter List of items and just update JCombobox with new ComboBoxModel.
Something like:
DefaultComboBoxModel comboModel = ((DefaultComboBoxModel)yourComboBox.getModel());
....
// invoke regex on yourArray
comboModel.removeAllElements();
for(int i = 0; i<yourArray.length; i++) {
comboModel.addElement(yourArray[i]);
}
[EDIT]
if you don't want to use two lists: one for actual data, two - for filtered data,
write custom ComboBoxModel where you can implement "hide" ability.

If i use a regular expression, i would have to store the values in another array ... which would imply that i would duplicate data? or am i missing something – Rory Lester Sep 29 '13 at 13:17

if you want to "hide", yes use 2 arrays no way. I don't see other way – Maxim Shoustin Sep 29 '13 at 13:18

because `removeAllItems` refers to `JCombobox` and here I use `DefaultComboBoxModel` – Maxim Shoustin Sep 29 '13 at 13:28

+1 for dynamically updating the model; for reference, a related example is seen [here](http://stackoverflow.com/a/7605780/230513). – trashgod Sep 29 '13 at 13:35
