Try this:
virtual void knobs(Knob_Callback f)
{
Knob* th = String_knob(f, &m_treeHash, "tree_hash", "Tree Hash");
Tooltip(f, "Hash of incoming op tree");
th->disable();
}

I do, yes, but I’m doing my initial development against the oldest version we
have in active use (trying to initiate a full-on switch to 6.2 in the next
month or so). If this is a version-specific bug/issue, that’s fine (it
shouldn’t cause any real issues), but I wanted to make sure I wasn’t missing
something.
Thanks guys,

Do you have 6.2 at hand to build against? I'm pretty sure the same thing would
work in 6.2

Thanks for the reply Peter, but that doesn't seem to be making a difference.
Just to be sure I'm not missing something, here's my knobs() function:
virtual void knobs(Knob_Callback f)
{
Knob* th = String_knob(f, &m_treeHash, "tree_hash", "Tree Hash");
Tooltip(f, "Hash of incoming op tree");
// th->set_flag(Knob::READ_ONLY); //What I was calling before
SetFlags(f, Knob::READ_ONLY); //Same result
}
When I load my plugin, I can select all the text in the String knob and delete
it. I can refresh it and the hash comes back, but there's nothing preventing me
from clearing it out every time.

Hey there dev list,
I’ve got a plugin that uses a String_knob. In my knobs() method, I’m
constructing it and then calling th->set_flag(Knob::READ_ONLY);. Pretty
basic stuff here.
However, the READ_ONLY flag doesn’t seem to have any effect. Is there a
way to get this to actually stick? Is this a version bug (this is being
built against 6.1v2)? Or is there another way I can display text that
can be expression-linked but is legitimately read only?
Thanks,
-Nathan
Try just:
SetFlags(callback, Knob::READ_ONLY);
after the String_knob() call.
Works for me in 6.3, and I can't think why 6.1 would be any different.
Regards,
Peter
