I have a couple of lists of integers that I want to store in a ValueTree, but I want to perform a task, using an updated list, atomically, ie. not receive callbacks for each item changing. I want to do this because the values are then sent, as a single list, through another API.
Making them all properties results in a callback per property, making them children results in a callback per child. Making sure they are always updated in a specific order, and a doing the update on the last one doesn’t work because if the last value doesn’t actually change, then I don’t get the callback. I can’t store them as an Array<var> because I export the ValueTree as XML.
The solution I am leaning towards is simply to remove and re-add the ValueTree to the parent, using the single valueTreeChildAdded callback to do the update. Anyways, just thought I would survey the community to see if anyone else has done something like this, and settled on a solution. Thanks in advance.
@cpr In addition to storing the values (int(s)) as properties, store a serialized version of the list in a special property (that you could potentially omit when dumping the tree to xml). This could be a comma separated list of int(s) or even some xml string (if you need the items to be named/organized).
@hhit, I had previously considered storing the list as a comma separated string property, but somehow I forgot about it. The list is associated with a preset type data structure, and thus doesn’t change with any high frequency, so I think this may be a cleaner solution than messing with removing/adding a child. Thanks for the suggestion.
