I'm not sure if this exists. From what I can tell fltk has not really 
been updated in quite a while. A lot of people who required GUI's these 
days seem to build them themselves using their preferred GUI toolkit and 
then link to Csound using the API. More and more people seem to be using 
Python for this as it is pretty easy to learn. In fact I would imagine 
that after learning Csound Python should not prove difficult at all. 
Finally, if you are working on windows Lettuce has a menu object you can 
use. Lettuce GUI components are different than fltk opcodes as they use 
the channel software bus to communicate with Csound. They're are some 
simple examples of the menu item in the installation directory. Note 
that to implement the menu you have to hard code it rather than drop it 
onto a GUI frame. The latest unreleased version of lettuce is available 
here: http://rorywalsh.ear.ie/Lettuce32Setup.exe The reason why this 
version hasn't been publically released is that I don't have time to 
support it!

Rory.

p.s. if you want cross-platform-ness use fltk!

I agree to the suggestions about Python/GUI, using Lettuce, and about
using FLTK for a simple crossplatform csound-only setup.
I just wanted to mention that I discovered today that FLTK actually
has a menu widget and a choice box, they are just not implemented as
csound opcodes (yet).
Maybe Gabriel has done it in his csound version ?

MacCsound is available on Intel Mac's afaik but cross-platform GUI's are 
great so if you don't feel like learning python or another GUI toolkit 
go ahead with fltk. Iain McCurdy has posted a load of great fltk 
instruments at http://iainmccurdy.org, perhaps they can give you more 
ideas. All the best.

Rory.

MacCsound is still only available as a PowerPC binary.  However, you can
usually run PPC binaries just fine on an Intel Mac due to Rosetta.  The
important thing to take into account is that you must install a PPC version
of Csound, not the Intel version.  Someone did recently report having
trouble with MacCsound on an Intel Mac (something about Csound not loading
plugins), but I don't think it was clear whether this was a universal issue.

Personally, I have to disagree with the many suggestions to implement a GUI
in C++ or Python.  If you are used to MacCsound's GUI widgets and just want
something similar that gives you the option to move to other platforms, then
using the FLTK opcodes is the obvious choice.  They are a bit clunkier to
use since you have to write code to create and position them (i.e. more
experimentation to get the layout you want), but the results will be
comparible.

Writing a host application on the other hand and trying to mix Csound with
an FLTK interface in C++ or some other toolkit has seemed like a tricky
project from the many questions and problems posted to the lists.  I have
not tried it, and perhaps some of the stickier issues have been solved now,
but it always seemed like there were issues with threading or GUI toolkits
conflicting, etc.  I am not saying that this route should be avoided
completely, just that I think the learning curve is much steeper than others
have estimated.

Subject: [Csnd] FLmenu?

Hi, everyone,

I’m considering implementing a new GUI for my csound improvisation orchestra.

I’m impressed by the FLxxx series of opcodes and in my tentative experiments they behave well. One GUI object that I would have expected to see, however, seems to be missing: a menu. What I mean is a kind of popup menu in which the current selection appears in somewhere in the body of a panel. The user clicks on it, and set of text-identified choices appears. When one of them is selected, the menu outputs a value that tells the csound orchestra which menu item was selected (or is currently selected.)

I’m reading documentation for 5.04, and I’m wondering whether the FL opcodes might have been extended after this version.

Or perhaps there’s another way to implement such a menu?

As always, thanks in advance for your help!

Sorry for the late reply to the initial question.
A workaround for a drop down menu functionality is to use the FL button bank and conditional interrogation in the instrument to determine the outcome.
Below a simple example.
