Hey everyone,
I have a Multiline_String_knob whose contents are a script. Since this knob
type forces a re-render every time anything in it changes (as opposed to only
on Enter or focus change, like the standard String_knob), I also have a
Bool_knob that I want to use to control whether changes to the knob’s contents
automatically force a re-render.
What I’m currently doing is the following:
int knob_changed(Knob* k) {
if (k->is("auto_evaluate")) {
if (_autoEval) knob("expression")->clear_flag(Knob::NO_RERENDER);
else knob("expression")->set_flag(Knob::NO_RERENDER);
return 1;
}
// ...
}
This is behaving somewhat strangely, and I feel like it’s due to an oversight
on my part. After this is called, the first character change in the text field
still triggers a re-render, but subsequent changes do not (as if the flag mask
state is one evaluation step ahead of the normal render process). This same
behavior occurs if I test the controlling knob’s value using k->get_value()
instead of just testing its storage variable.
So am I right that I’m overlooking something? Or is this a known issue?
Thanks,
-Nathan_______________________________________________
