Research direction
Start by tracing the ofParameter value access and the existing changedE event behavior. Compare the referenced getRef() idea with current access patterns and determine how reference access should behave when events are not being observed. Done means a documented, tested API decision that preserves the existing event semantics.
Written by the indexing model from the issue text.
Description
I'm assuming access is kept private because that would otherwise mess with the changedE events, but it would be really useful for situations where we're not listening for events. The obvious use-case is for GUI systems that use value references directly.
I've already seen a few different "hacks" for dealing with this, so it feels like it's a common request:
- https://github.com/jvcleave/ofxSyncedParameter
- https://github.com/elliotwoods/ofxCvGui
- https://github.com/prisonerjohn/ofxPreset
I'm thinking something along the lines of:
ParameterType & getRef() {
return obj->value;
}
