Combo box or list box?

When I did a search on “Combo box” it came back with more than 200
entries.

When I was programming in Visual Basic a Combo Box was a
Combination(Combo) of a text box and a list box. The user would enter
data in the text box and the list box would change depending on what was
typed. This happened as each character was typed as VB deals with events
(key press) and text_box.text.

Does Ruby have another definition of Combo box? If so where can I find
information on how to use it?

All of the questions that I looked at seemed to be talking about a List
box, not a VB Combo Box…

Some context would help, which GUI are you using?

This was just a comment on what I found when I did a search where it
seems to me that people are using the WRONG term for a list box by
calling it a combo box.

The “Visual” in VB is about GUI programming. I’m not surprised that you
find more standard terminology in a language geared around that kind of
thing.

Ruby has many options for GUIs, none of them are built in (I don’t count
Tk as “built-in”), and many of them written in other languages. I agree
with your basic definition of Combo Box and List Box, but there are many
variations and many people using / writing them who don’t always use the
exact same terminology.
