How to set padding or margin on GridLayout ...

[Jehyeok]

I redefined GridLayout for reusable reason.
Grid has padding, but GridLayout doesn't.
Do you have any idea to use padding or margin on it?

Rectangle {
  width: 250
  height: childrenRect.height

  MyGridLayout{
  // padding or margin : 10
    MyGridLayout{
      orientation:1
      text { text: "input" }
      textfield { }
    }
    Button { text: "OK"
      
    }
  }

}

MyGridLayout.qml

GridLayout{
	property int orientation : 0 // 0: vertical, 1: horizontal
	property double spacing : 10
	property double margin : 0

	columns : (orientation == 0) ? 1 : 0
	rows : (orientation == 0) ? 0 : 1
	columnSpacing : spacing
	rowSpacing : spacing

	width : parent.width
	height : (visible) ? childrenRect.height : 0
	//x : margin
	//y : margin
	//width : parent.width - (margin * 2)
	//height : childrenRect.height + margin * 2
	//Layout.preferredHeight: childrenRect.height + margin
	Layout.alignment : Qt.AlignTop

	flow : (orientation == 0) ? GridLayout.LeftToRight : GridLayout.TopToBottom
}
