import QtQuick.Window 2.0
import QtQuick.Layouts 1.1ApplicationWindow {visible: truewidth: 700height: 480title: qsTr("Hello World")Grid{anchors.right:parent.rightanchors.rightMargin: 60anchors.top:parent.topanchors.topMargin: 20flow:Grid.LeftToRightspacing: 0width: 360height: 400clip: trueRepeater{id:numGridRepmodel:["1","2","3","","4","5","6","","7","8","9","",&
