I am dynamically trying to add Columns to my UI and then anchor them with the parent and nearby element, however parent is always null.

columns[i] = Qt.createComponent("Column.qml");

columns[i].createObject(rectangle1,{id : "column".concat(i), "anchors.left" : name, "width" :getcolwidth(rectangle1) });

Here anchors.left is column0 and in the Column.qml file, I have

anchors.leftMargin: 15
anchors.bottom:parent.bottom
anchors.bottomMargin: 5
anchors.top: parent.top
anchors.topMargin: 5

The parent should point to rectangle1 but instead it points to null.

It's a lucky guess but shouldn't it be `"anchors.fill"`? As `anchors.left` requires xxx.left/right not just id. – Nadarian Aug 04 '14 at 13:26
@Nadarian name actually contains column0.right, the actual code, `name = "column".concat(i-1).concat(".right");` – HackToHell Aug 04 '14 at 15:02
Well then for i=0 your previous column doesn't exist – Nadarian Aug 04 '14 at 16:31
@Nadarian i starts at one, I tried removing the name param completely and it still didn't work – HackToHell Aug 05 '14 at 12:33
