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,

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
