Friends help me, how does it do to execute a qml function from an Item inside a Parallel Thread to not freeze UI?

example:

Import QtQuick 2.7

MyItem {

 Function foo () {
    
     // script
     For (var i = 0; i <1000000; i ++)
     {
         Console.log ( "Number:" + i)
        
     }
 } // end function

} // end MyItem

Hi! See WorkerScript QML Type.

More in Work Script I can not work with objects within a function. Is there any way for this?

 // script 
anotherObj.foo()

} // end function

} // end MyItem

No, more isn't possible because JS is single-threaded by design. These worker scripts (or web workers in other contexts) are more or less just a hackish work-around for that. Keep in mind that JS is meant only for very short / simple code. Executing it is very inefficient, so you should really do all the complicated non-GUI stuff in C++.

So how do I call a function from an object without freezing my UI?
