How to get mouse position when handling SplitView

fromis_9

Hi. I'm using QtQuick2 SplitView for my application.
I need the mouse position when users click handle inside of the splitview.
I included MouseArea inside of the SplitView for that, but it didn't work.
How can I do it?

I make my own split view for my purpose.

import QtQuick 2
import QtQuick.Layouts

Item {
  id: splitView
  RowLayout { anchors.fill: parent
    spacing: 0
    Rectangle { Layout.fillWidth: true; Layout.fillHeight: true
      id: leftItem
      color: "red"
    }
    ToolSeparator { Layout.fillHeight: true
      id: handle
      property int leftLimit: 0
      property int rightLimit: splitView.width
      MouseArea { anchors.fill: parent
        id: handleMouseArea
        acceptedButtons: Qt.LeftButton
        cursorShape: Qt.SplitHCursor
        onMouseXChanged: {
          /* Mouse position in the SplitView*/
          var pos = mapToItem(splitView, mouse.x, mouse.y)
          if (pressed) {
            var xPos = pos.x - handle.width / 2
            if (handle.leftLimit < xPos && xPos + handle.width < handle.rightLimit) {
              /* This is basic functionality of SplitView */
              handle.x = xPos
              leftItem.width = handle.x
              rightItem.x = handle.x + handle.width
              rightItem.width = splitView.width - leftItem.width - handle.width
            }
          }
        }
      }
    }
    Rectangle { Layout.fillWidth: true; Layout.fillHeight: true
      id: rightItem
      color: "blue"
    }
  }
}

any better?
