import QtQuick
import QtQuick.Controls

Window {
   id: window

   width: 1024
   height: 720

   visible: true
   title: qsTr("Hello World")

   TreeView {
      anchors.fill: parent
      model: treeModel

      selectionModel: ItemSelectionModel {
         onCurrentIndexChanged: console.log(currentIndex)
      }

      delegate: TreeViewDelegate {
         highlighted: current
      }
   }
}
