    Hi! I've got a question about dynamic object creation. So, my goal is to create some dynamic objects and store them in a property like @property list<Item> items@
    but when i try to assign something to it, it has no effect! @items[0]=myComponent.createObject(someObject)@
    is there a way do it (to append something to the list)?

      Are you using QtQuick 1.x or QtQuick 2.0? With QtQuick 2 you can use a "var" property to store an array of items which can be dynamically added to etc. ListReference properties are generally intended to be lightweight and "static", I believe.

      /edit: turns out that you can do:

      @
      property list<Item> il
      Component.onCompleted: {
      // define array
      var someItemArray = [];

         // push c1
         for (var i = 0; i < il.length; ++i)
             someItemArray.push(il[i]);
         someItemArray.push(c1);
         il = someItemArray;
      
         // push c2
         for (var i = 0; i < il.length; ++i)
             someItemArray.push(il[i]);
         someItemArray.push(c2);
         il = someItemArray;
      
         for (var i = 0; i < il.length; ++i) console.log("il[i] = " + il[i]);
      

      }
      @

      [Edit: Used proper @ code formatting. -mlong]
