I tried with

printks "'%s'\n",1, gSgm

Nothing changed, every second the empty string was printed and I changed selection in the widget.

my guess: chnget queries the channel at perf-time, prints prints the content of the S-variable at init-time. Try printsk instead, and test it without any external code

I also tried that, to no avail

I would say there is something wrong with chnget to a string...

I don't think it's chnget, if you use chnset within Csound it'll work fine:

gSgm init "blank"
chnset gSgm, "gm"

Maybe there's either an issue in CsoundQt with setting channels
(whether a bug or how it's being used in your particular project)?  Do
you have an example that runs with CsoundQt that has the widgets in
the project?

i think you are right.  chnget is only reading the string at init-time 
(at least in csoundqt with a widget).  using invalue instead works for me.

The OP did not mention using csoundqt.

I am sorry, but I think this was clear enough when I wrote: in Qt I have widget called "gm"

On 03.11.20 18:53, Steven Yi wrote:

I don't think it's chnget, if you use chnset within Csound it'll work fine:

gSgm init "blank"
chnset gSgm, "gm"

Maybe there's either an issue in CsoundQt with setting channels
(whether a bug or how it's being used in your particular project)?  Do
you have an example that runs with CsoundQt that has the widgets in
the project?

The OP did not mention using csoundqt.

I think it might be a misunderstanding of how the menu widget works in
CsoundQt. I see the information mentioned at:

https://csoundqt.github.io/pages/widgets.html

That it just sends an index value and not the string. I didn't see any
options in the widget properties to send string values either.  (That
all said, I don't use CsoundQt so someone else could provide better
feedback.)

right.  the menu widget will not at all send a string.  so this is solved.

the comparison i mentioned between chnget:S and invalue in csoundqt was 
with a line edit widget.  i think only invalue is updating the string if 
changed during performance.
