qt - Set rotation point of Rectangle -

is there way set rotation point in rectangle , use rotation property without other additional component? want rotate rectangle binding property of rotation: value * 180 this

rectangle{     id: body     rotation: value     anchors.centerin: parent.center     antialiasing: true } onvaluechanged: body.rotation = value 

i got rotation around left upper corner of parent. please me understand behavior or suggest me way implement rotation on center.

rotation property rotates item clockwise around transformorigin property 1 of these 9 points :

so can rotate around 1 of them :

rectangle{     id: body     rotation: value     transformorigin: item.center     anchors.centerin: parent.center     antialiasing: true } 

if want rotate around arbitrary point should use rotation transform type :

rectangle{     id: body     transform: rotation { origin.x: 25; origin.y: 25; angle: value}     anchors.centerin: parent.center     antialiasing: true }
