Combobox events

[Jekutin]

I have been trying to make an accounting program, but got any further from the very beginning. I need a combobox which has a drop down list with 2 columns, and it opens when the user starts to write to the combobox text field. It should also have a incremental search feature. This kind of combobox seems to be almost impossible to find, so I decided to make my own. The problem now is, that I cannot get event from the text field, when the user starts to type. I have tried several different approaches. Last was an idea to use combobox in Netbeans palette and then copy the code. Unfortunately this does not work. None of the *key* actions seem to be fired. Only ActionPerformed works, but that is not the one I can use. I have tested with editable and not editable combo boxes.

My question is now, does these *key* events fire and if yes, how to use them. If not, should they be taken away from the events list.

JCombobox is a slightly unusual component in that it is a compound component. The combobox fires action events, the subcomponents fire key, mouse and some other events... check out the combobox tutorial...
