Widget updating

Cabbage slugs
1

Hello
I’m trying to understand whether is possible to use a widget like texteditor in order to output some text to the user (like a small display area).
I defined it as:
texteditor bounds(176, 16, 400, 121), channel(“debug1”), fontSize(“12”), active(“1”), scrollbars(1), wrap(1), fontColour(124, 210, 0), colour(0, 0, 0, 100)

I’m trying to use it with instruct:
cabbageSet “debug1”, “text”, SText

But nothing happens, except for the first time, the other times the text will not change.

Thank you

Sergio

Hi @idranoels, welcome to the forum. :clap:

As you can see, this can be done, but you need to use the i-rate version of cabbageSet

<Cabbage>
form caption("Test") size(400, 150), colour(58, 110, 182), guiMode("queue")
texteditor bounds(16, 10, 371, 107) fontSize(70), channel("texteditor10000"), readOnly(1), wrap(1), 
</Cabbage>

ksmps = 32

    SWords[] init 5
    SWords[0] = "Of "
    SWords[1] = "course "
    SWords[2] = "this "
    SWords[3] = "is "
    SWords[4] = "possible."
    cabbageSet metro(2), "texteditor10000", sprintfk("text(\"%s\")", SWords[int(random:k(0, 5))])
endin

Thank you Rory
Is there a tutorial that explains in which case I should use k-rate functions and in which case I should use i-rate functions?
Thank you

The Csound FLOSS manual is a great resource. Here is the section on init (i-rate) and performance (k-rate) passes. Let me know if you have any further questions after reading this. It’s quite important to get your head around this principal, it pops up in Csound all the time.
