ArcEngie开发-添加MapFrame

下面是添加图框的基本方法和步骤：

///<summary>///添加地图框架///</summary>///<paramname="sender"></param>///<paramname="e"></param>private void wndBtnAddMapFrame_ItemClick(objectsender, ItemClickEventArgse){   IEnvelope envelop= new EnvelopeClass();   envelop.XMin= 2;   envelop.YMin= 2;   envelop.XMax= 5;   envelop.YMin= 5;   IMapFrame p_MapFrame= newMapFrameClass();   p_MapFrame.Map=new MapClass();   IElement ele= p_MapFrame as IElement;   wndPageLayout.AddElement((IElement)p_MapFrame,envelop,null, null, 0);    IGraphicsContainerSelect graphSelect = wndPageLayout.PageLayoutas IGraphicsContainerSelect;   graphSelect.SelectElement(ele);   wndPageLayout.Refresh(esriViewDrawPhase.esriViewGraphicSelection,null,null);}

本例中自己定义了一个Envelope，在实际开发中，这个图框的大小可以通过绘制矩形框获取，或者根据现有页面自动生成，如下：

        private void wndBtnAddMapFrame_ItemClick(object sender, ItemClickEventArgs e)        {                        double width, height;            wndPageLayout.Page.QuerySize(out width, out height);            IEnvelope pEnvelop = new EnvelopeClass();            pEnvelop.PutCoords(0, 0, width, height);            pEnvelop.Expand(0.5, 0.3, true);            IMapFrame p_MapFrame = new MapFrameClass();            IMap pMap = new MapClass();            p_MapFrame.Map = pMap;            p_MapFrame.Map.Name = "New Data Frame";            IElement ele = p_MapFrame as IElement;            wndPageLayout.AddElement((IElement)p_MapFrame, pEnvelop, null, null, 0);            IGraphicsContainerSelect graphSelect = wndPageLayout.PageLayout as IGraphicsContainerSelect;            graphSelect.SelectElement(ele);            wndPageLayout.Refresh(esriViewDrawPhase.esriViewGraphics, null, null);             }

当然，与这种处理方法效果等价的最简单的办法是直接调用添加MapFrame的ICommand命令，如下：

            ICommand pCmd = new ControlsPageNewMapCommand();            pCmd.OnCreate(wndPageLayout.Object);            pCmd.OnClick();
