I've done this.

But params.hasDefaults() should be checked on every object-hit (it's
changed by several objects). So it should be something like
if (ob == any_object) {
BufferParams params = lv_->buffer()->params;
setEnabled(class_->button_reset_defaults, !params.hasClassDefaults());
}
Is that possible?
