How to make choices visible in a JComboBox?

[Aaron Fude]

Hi,

I'm writing a JComboBox with a custom Editor. The idea is that when
the user inputs a string, the choices are narrowed down to match the
input.

When the user starts typing, how does one reveal the available
choices? In other words, how does one make the choices open up as if
the little "arrow down" next to the combo box is pressed?

Many thanks in advance,

Aaron

Have you taken a look at Glazed Lists
(http://publicobject.com/glazedlists/)? Maybe they already do what you
are trying to build.

Just remove values when they become invalid, and add them back as they
become valid. Perform this calculation every time the text is
changed.

There is nothing there on the topic. You are getting dangerously close
to being labeled a spammer.

Another possible route is to use a JList which always displays all the
choices.
