027TOCControl上实现右键.docx

1、027TOCControl上实现右键【027 】TOCControl 上实现右键-目录：A1 第一种方法： contextMenuStripA2 第二种方法： IToolbarMenu1AICommandSubType接口2AIToolbarMenu接口-第 A1 个第一种方法：contextMenuStrip：第一步：新建另外一个窗体首先要定义一个全局变量窗体要带参数，以便将ILayer ILayer。传递过来。获取属性列表。ILayer pLayer;/定义一个虚拟的ILayerpublicForm2(ILayer layer)InitializeComponent();pLayer =

2、layer;/将赋值的layer再赋值给pLayer，这样pLayer就是实体了privatevoidForm2_Load( objectsender, EventArgs e)IFeatureLayer pFeatureLayer = pLayer as IFeatureLayer;IFeatureClass pFeatureClass = pFeatureLayer.FeatureClass;IFeatureCursor pFeatureCursor = pFeatureClass.Search(null, false);IFeature pFeature = pFeatureCursor

3、.NextFeature();IFields pFields = pFeatureClass.Fields;DataTable pTable =new DataTable();for ( int i =0; i pFields.FieldCount; i+)/获取所有列DataColumn pColumn = pTable.Columns.Add(pColumn);new DataColumn(pFields.get_Field(i).Name);while(pFeature !=null)DataRow pRow = pTable.NewRow();for ( int i = 0; i pF

4、ields.FieldCount; i+)/添加每一列的值pRowi = pFeature.get_Value(i);pTable.Rows.Add(pRow);pFeature = pFeatureCursor.NextFeature();dataGridView1.DataSource = pTable;第二步：建立右键菜单项添加一个 ContextMenuStrip 控件，然后增加几个菜单项。特别注意加入一个菜单项为 “显示属性 ”。判断在什么情况下显示右键菜单。ILayer m_Layer; / 沟通图层private void axTOCControl1_OnMouseDown( o

5、bjectITOCControlEvents_OnMouseDownEvent e)sender,if(e.button =2)esriTOCControlItem Item =esriTOCControlItem.esriTOCControlItemNone;IBasicMap pBasicMap =ILayer pLayer = nullobject other = nullobject index = nullaxTOCControl1.HitTest(e.x, e.y,pLayer, ref other, ref index);m_Layer = pLayer;null;ref/ 实现

6、赋值Item,refpBasicMap,refif(Item = esriTOCControlItem.esriTOCControlItemLayer)/点击的是图层的话，就显示右键菜单contextMenuStrip2.Show(axTOCControl1, new System.Drawing.Point(e.x, e.y);/ 显示右键菜单，并定义其相对控件的位置，正好在鼠标出显示privatevoid显示属性ToolStripMenuItem_Click(objectsender,EventArgs e)Form2 frm =new Form2(m_Layer);/ 定义窗体，注意窗体

7、的参数frm.Text =Attributes of + m_Layer.Name;/ 显示标题frm.ShowDialog();/ 以对话框形式显示窗体效果如下所示：- 第 A2 个 第二种方法： IToolbarMenu ：第一步：新建菜单框架：IToolbarMenu m_TOCMapMenu = new ToolbarMenu();IToolbarMenu m_TOCLayerMenu= new ToolbarMenu();第二步：在菜单框架中加入菜单项，用AddItem方法实现：m_TOCLayerMenu.Caption =Sub Menu ;/二级菜单设置名称m_TOCLayer

8、Menu.AddItem(new ControlsMapZoomInToolClass(),0,0,false,esriCommandStyles.esriCommandStyleIconAndText);m_TOCLayerMenu.AddItem(new ControlsMapZoomInToolClass(),0,1,true,esriCommandStyles.esriCommandStyleIconAndText);m_TOCLayerMenu.AddItem(new ControlsMapZoomInToolClass(),0,2,false,esriCommandStyles.e

9、sriCommandStyleIconAndText);m_TOCLayerMenu.SetHook(axMapControl1);/作用在 MapControl上面m_TOCMapMenu.AddItem(new ControlsAddDataCommandClass(),0,0,false,esriCommandStyles.esriCommandStyleIconAndText);m_TOCMapMenu.AddItem(new ControlsMapFullExtentCommand(),0,1, false,esriCommandStyles.esriCommandStyleIcon

10、AndText);m_TOCMapMenu.AddItem(new ControlsMapZoomInToolClass(),0, 2,true,esriCommandStyles.esriCommandStyleIconAndText);m_TOCMapMenu.AddItem(new ControlsMapZoomOutToolClass(),0,3,false,esriCommandStyles.esriCommandStyleIconAndText);m_TOCMapMenu.AddItem(new ControlsPagePanToolClass(),0,4 ,false,esriC

11、ommandStyles.esriCommandStyleIconAndText);m_TOCMapMenu.AddSubMenu(m_TOCLayerMenu,5, false);m_TOCMapMenu.SetHook(axMapControl1);第三步： TOCControl 的 MouseDown 事件：private void axTOCControl1_OnMouseDown( object ITOCControlEvents_OnMouseDownEvent e)sender,esriTOCControlItem item =esriTOCControlItem.esriTOC

12、ControlItemNone;IBasicMap map = null ;ILayer layer = null ;object other = null ;object index = null ;axTOCControl1.HitTest(e.x,e.y,refitem, refmap, reflayer,refother,ref index);if(e.button =2 )if(item =esriTOCControlItem.esriTOCControlItemMap)axTOCControl1.SelectItem(map,null );m_TOCMapMenu.PopupMen

13、u(e.x, e.y, axTOCControl1.hWnd);实现效果如下：public int AddItem (object item,int SubType,int index,bool beginGroup,esriCommandStyles Style);第一个参数：菜单项的内容，功能实现。第二个参数：对于一个工具定义多个 type 的时候，才会用到，每一个 int 代表一个新的实现。第三个参数：索引值，在菜单项上面显示的位置。默认为 -1 ，按书写顺序排序。第四个参数：是否开始一个新组，就是在其上面有一个 “”的效果。第五个参数：显示样式。用 SubType 实现：首先：建立工具

14、，这个时候类不仅要继承 BaseCommand 类，还要继承ICommandSubType 接口- 第 1A 个 ICommandSubType 接口：Provides access to members that define a subtyped command.MembersDescriptionGetCountThe number of commands defined with this CLSID.SetSubTypeThe subtype of the command.usingusingusingusingusingusingusingusingSystem;System.Dr
