在googleearthcomapi中侦听鼠标事件的样板代码

如果您使用免费的Winforms Geplugin控件库,这并不难-只需遵循以下简单步骤

您需要告诉web浏览器对象您要侦听mousemove事件

 geWebBrowser.AddEventListener(gePlugin.getGlobe(), "mousemove");

geWebBrowser.KmlEvent += GeWebBrowserKmlEvent;


private void GeWebBrowserKmlEvent(object sender, GEEventArgs e)
        {
            // if it is a mouse event
            if (null != sender as IKmlMouseEvent)
            {
                handleKmlMouseEvents((IKmlMouseEvent)sender, e.Data);
            }
            else
            {
                MessageBox.Show(GEHelpers.GetTypeFromRcw(sender));
            }
        }

 private void handleKmlMouseEvents(IKmlMouseEvent mouseEvent, string action)
        {
            string currentTarget = mouseEvent.getCurrentTarget().getType();

            switch (action)
            {
                case "mousemove":
                    {
                        DoMouseMove(mouseEvent);
                        break;
                    }

                case "click":
                    {
                        DoClick(mouseEvent, currentTarget);
                        break;
                    }
                case "mousedown":
                    {
                        DoMouseDown(mouseEvent, currentTarget);
                        break;
                    }
                case "mouseup":
                    {
                        DoMouseUp(mouseEvent);
                        break;
                    }
            }
        }

 private void DoMouseMove(IKmlMouseEvent mouseEvent)
 {

 }
