  Key_Cancel: 3,

  // CursorShape
  ArrowCursor: 0,
  UpArrowCursor: 1,

}


2.  the property

    createSimpleProperty("enum", this, "cursorShape");

3.  CSS cursor change

    this.dom.onmouseover = function(e) {
        self.containsMouse = true;
        self.dom.style.cursor = cursorShapeToCSS();
        self.entered();
    }
    this.dom.onmouseout = function(e) {
        self.containsMouse = false;
        self.dom.style.cursor = "auto";
        self.exited();
    }
    this.dom.onmousemove = function(e) {
        if (self.enabled && (self.hoverEnabled || self.pressed)) {
            var mouse = eventToMouse(e);
            self.positionChanged(mouse);
            self.mouseX = mouse.x;
            self.mouseY = mouse.y;
        }
    }
    
    function cursorShapeToCSS(){
        var cursor = "auto";
        switch (self.cursorShape) {
          case Qt.ArrowCursor: cursor = "default"; break;
          case Qt.UpArrowCursor: cursor = "auto";break;
          case Qt.CrossCursor: cursor = "crosshair";break;
          case Qt.WaitCursor: cursor = "wait";break;
            case Qt.IBeamCursor: cursor = "auto";break;
            case Qt.SizeVerCursor: cursor = "auto";break;
            case Qt.SizeHorCursor: cursor = "auto";break;
            case Qt.SizeBDiagCursor: cursor = "auto";break;
            case Qt.SizeFDiagCursor: cursor = "auto";break;
            case Qt.SizeAllCursor: cursor = "auto";break;
            case Qt.BlankCursor: cursor = "auto";break;
            case Qt.SplitVCursor: cursor = "auto";break;
            case Qt.SplitHCursor: cursor = "auto";break;
            case Qt.PointingHandCursor: cursor = "pointer";break;
            case Qt.ForbiddenCursor: cursor = "not-allowed";break;
            case Qt.WhatsThisCursor: cursor = "auto";break;
            case Qt.BusyCursor: cursor = "progress";break;
            case Qt.OpenHandCursor: cursor = "auto";break;
            case Qt.ClosedHandCursor: cursor = "move";break;
            case Qt.DragCopyCursor: cursor = "auto";break;
            case Qt.DragMoveCursor: cursor = "auto";break;
            case Qt.DragLinkCursor: cursor = "auto";break;
            case Qt.LastCursor: cursor = "auto";break;
            case Qt.BitmapCursor: cursor = "auto";break;
            case Qt.CustomCursor: cursor = "auto";  break;
        }
        return cursor;
    }
