hi all -

as the chnget opcode is much more cpu-friendly in csoundqt than the 
invalue opcode, i try to change some examples in this way. but in 
replacing invalue by chnget has one major issue which i don't know how 
to solve.

say you have a checkbox, and it is checked, so has the value 1. this 
line of code will return 1 a value of kCheck when running:
kCheck invalue "my_checkbox"

but this line will return 0 for kCheck in the same situation:
kCheck chnget "my_checkbox"

is this as it should be? any ways to retrieve the correct widget value 
at start?

thanks -

Hi,

I don't get the same result. With a small test orchestra:

chn_k "check", 1

schedule 1,0,1
instr 1
	;kval invalue "check"
	kval chnget "check"
	printk2 kval

endin

the output is correctly
SECTION 1:
 i1     1.00000

when the checkbox is checked.

Didn't you forget the chn_k declaration?
There is a script in Scripts->Editor->invalue_chnget.py that will insert the 
declarations for you, if you have a lot of channels.

Best!

thanks very much, tarmo. this did the trick. i did not know that it was 
necessary to declare the channel in advance.

btw, the script add_chn_k.py did not only add the chn_k lines, but also 
creates sliders without asking. i suppose these lines are to be removed:

for (i, chn) in enumerate(channels):
     q.createNewSlider(i*30, 40, chn)
