How to move a cell in GridLayout - QML?

Question

Considering the documentation of GridLayout, here is what I have tried:

import QtQuick 2.4
import QtQuick.Window 2.2
import QtQuick.Layouts 1.1

Window
{
    visible: true

    MainForm
    {
        GridLayout {
            id: gridLayout
            columns: 3

            height: 100
            width: 100
            property int oneRow: 0
            property int oneCol: 0

            Rectangle { id: one; Layout.row :gridLayout.oneRow; Layout.column: gridLayout.oneCol;
                height: 50; width: 50; color: "brown"}

            Rectangle { height: 50; width: 50; color: "red" }
            Rectangle { height: 50; width: 50; color: "blue"}
            Rectangle { height: 50; width: 50; color: "green"}
            Rectangle { height: 50; width: 50; color: "yellow"}
        }

        Component.onCompleted:
        {
            gridLayout.oneRow = 2
            gridLayout.oneCol = 2
        }
    }
}

If I comment out this code from Component.onCompleted,

gridLayout.oneRow = 2
gridLayout.oneCol = 2

I get:

Whereas I want that brown square to "move to" the second row's last column.
So, I wrote:

gridLayout.oneRow = 1
gridLayout.oneCol = 2

in Component.onCompleted.

but then, I got the following:

which is NOT what I wanted.

Please help.

What if you set the Brown rectangle last in your declaration? — Thomas Ayoub
@Thomas there is a reason I double quoted the words "move to" in OP. — Aquarius_Girl
I see a lot of weird things here, sorry if the stupidness of my question hurt you — Thomas Ayoub

If you wish to change the cell number of some item in the GridLayout, then you need to assign the initial row number and column number to all the elements _yourself_, and then change the position of the desired item dynamically as shown below:

import QtQuick 2.4
import QtQuick.Window 2.2
import QtQuick.Layouts 1.1

Window
{
    visible: true

    MainForm
    {
        GridLayout {
            id: gridLayout

            height: 100
            width: 100

            property int oneRow: 0
            property int oneCol: 0
            Rectangle { id: one;
                Layout.row :gridLayout.oneRow; Layout.column: gridLayout.oneCol;
                height: 50; width: 50; color: "brown"}

            property int twoRow: 0
            property int twoCol: 1
            Rectangle { id: two;
                Layout.row :gridLayout.twoRow; Layout.column: gridLayout.twoCol;
                height: 50; width: 50; color: "red" }

            property int threeRow: 0
            property int threeCol: 2
            Rectangle { id: three;
                Layout.row :gridLayout.threeRow; Layout.column: gridLayout.threeCol;
                height: 50; width: 50; color: "blue"}

            property int fourRow: 1
            property int fourCol: 0
            Rectangle { id: four;
                Layout.row :gridLayout.fourRow; Layout.column: gridLayout.fourCol;
                height: 50; width: 50; color: "green"}

            property int fiveRow: 1
            property int fiveCol: 1
            Rectangle { id: five;
                Layout.row :gridLayout.fiveRow; Layout.column: gridLayout.fiveCol;
                height: 50; width: 50; color: "yellow"}
        }

        Component.onCompleted:
        {
            gridLayout.oneRow = 1
            gridLayout.oneCol = 2
        }
    }
}

Now, as you can see the following code in Component.onCompleted moves the brown rectangle to the 2nd row's 3rd column.

Component.onCompleted:
  {
      gridLayout.oneRow = 1
      gridLayout.oneCol = 2
  }
