Best way to remove dynamic qml object from a listmodel

[johngod]

I have self destroying qml objects in a list model.
When they are destroyd I want to remove then from the listmodel, but I dont know their index. So to find the index I'm setting a flag to false when they are about to be destroyed, then I iterate the list to find the object index. It works, but it looks ugly and hacky, is there a better way to find the object list index from inside the object ?

This is what I did:

ListModel {
        id: activeEnemiesList
 }

    Component.onCompleted: {
    
        var enemy2count = 55
        for (i = 0; i < enemy2count;i++) {
            var enemy2 = lib.createItem("Enemy02.qml", parent) //dynamic creation
        }
   }

Enemy02.qml :

Item {
    id: enemy02
    property bool timerRunning: y > spaceLimitYmin && y < spaceLimitYmax
    property bool alive: true

    onTimerRunningChanged: {
        if (timerRunning) {  // add object to the list
            activeEnemiesList.append({"obj": enemy02})
            console.log("added enemy to the list, size is "+activeEnemiesList.count)
        } else { //remove object from the list and destroy it
            alive = false
            for(var i = 0; i < activeEnemiesList.count; i++) {
                if (activeEnemiesList.get(i).obj.alive === false) {
                    activeEnemiesList.remove(i,1)
                    enemy02.destroy()
                    break;
                }
            }
        }
    }

How are you displaying the individual objects. It must be through delegate. You can use 'index' property inside the delegate which gives you the information required.

Thats the problem, I'm not using any delegates so no index available. They are just dynamic qml rectangles that self display randomly on screen, when created. I'm only using a Listmodel to keep track of them to do stuff like collision detection (I could have also used a javascript array instead of listmodel).
