Disable an option in a combobox

[hisefilo]

Hi guys!
How can I make an item not selectable or disabled on a combo box?
Meaning it still visible (grayed usually) but not selectable.
Couldn’t find any reference to this anywhere.
Thanks in advance

@hisefilo I wondered the same recently but also found nothing in the docs. I don't know if it's possible.
For my project I'm using several cBox with the same choices. I ended up using a "if user selects a cBox value which is already used by another one, change the value of the other one" system

does this work?

if (value == optionIDidntActuallyWant)
    return;
else
    doNormalCBThings();

@iamlamprey this should work for that purpose but there's no laf function to grey the value out AFAIK

@Matt_SF You can draw individual items in a combo box, so just draw it with a grey colour.

yeh im trying to write up a quick snippet but i can't remember how to push the combobox values into an array... brain too sleepy

Edit: there actually is one issue with using return; the value of the ComboBox still changes, despite it ignoring whatever code you put after the return call.

You might have to use a panel if you depend on the value of the combobox not changing, unless there's some sneaky way to ignore the value update before the actual control callback, which would kill 2 birds with 1 function

@iamlamprey local items = ComboBox.get("items).split("\n");

the value of the ComboBox still changes,

So change it back ;)

yeah I think "...2022" is actually a bit narrower than the time frame I've been stupid in....
