tree onSelectChange when all the items are selected

Webix JS
1

Hi, is it possible to trigger the onSelectChange event of the tree only when all items are selected and not for each one of them when I select the items with the tree.select([…]) method?

Here is a snippet to show you what i would like to be the result:

try to check selecteds length

    onSelectChange: function() {
      var selected_ids = $$("tree").getSelectedId(true);
      if(selected_ids.length==$$("tree").count())
        webix.message(selected_ids.join(","));
    }

but in this way it works only if I select all the items.

In my snippet I select 3 out of 6 total items, in this case I don’t see any message.

Beside, in my real use case, i don’t know how many items I will select, it depends on user actions.
