In an item (A) which handle the position of his sons (B, BB, BBB) (e.g.: a RowLayout) you don’t have to put anchors.fill: parent to one of the sons, if you do this the son’s position management will be broken.

In this example the rectangle B is used to do a background which is wrong, the right solution is to put this rectangle at the root, as a parent of the RowLayout.

[source,javascript]

RowLayout { id: A Rectangle { id: B anchors.fill: parent // don’t do this ! color: “red” }

Rectangle {
	id: BB
}

Rectangle {
	id: BBB
} }
