Dynamic object's id in QML
-
i am generating new QML object with the following code:
The polygon object is a type that i define with C++:@var newObject = Qt.createQmlObject("import MyTypes 1.0;"+
"import QtQuick 1.0;"+
"import Qt 4.7;"+
"Polygon {"+
"id:_"+polygonID+";"+
//"anchors.fill:parent;"+
"x:645; y:0;"+
//"width: 0; height: 0;"+
"color: "+polygonColor+";"+
//"scale:0.3;"+
"vertices:["+
polygonPointsString+
"]"+
"Component.onCompleted:{ container.pntx= _"+polygonID+".leftAndTopOfBoundingRect().x;"+
"container.pnty= _"+polygonID+".leftAndTopOfBoundingRect().y;"+
"}"+
"}",
parentObj, "dynamicSnippet3");console.log"id:"+(newObject.id);
@after
@ console.log"id:"+(newObject.id);@
line it writes:id:undefined
but if i write
@ console.log"id:"+(newObject.x);@
line it writes:645 the true answer
where am i wrong, why id is undefined?
thanks

Also, note that while dynamically created objects may be used the same as other objects, they do not have an id in QML.

thanks, i have looked at that page but did not see that line.
if so how can i access to that objects?
@Scale {
id: scaleItem
origin.x: 0; origin.y: 0; xScale: 1.2; yScale:1.2
}@
i must access this element,and assign it to "transform" variable of my component and i think i can do it using id, if there is no id, how?
thanks very much for the reply -
You use variable of that dynamically created element (newObject.transform ).

thanks,
i can not try it at the moment but i need to write@newObject.trasnform=scaleItem;//scale item id@
i can not do it because i will generate scale item dynamically too.
thus can i write
@newScaleObject=createQMLObject("import Qt 4.7; Scale{origin.x:0; blah blah}");@
and can i write:
@
newObject.transform:newScaleObject@?
is it possible?
