AE中实现 Control中的各种图形工具的方法.doc

添加命名空间using ESRI.ArcGIS.SystemUI;using ESRI.ArcGIS.Controls;A类：前面有Controls后面有tool的工具都可以用同一类的代码实现（最后的tool或toolclass都可以）示例：privatevoid放大ToolStripMenuItem_Click(objectsender,EventArgse)ICommandCmd=newControlsMapZoomInTool();Cmd.OnCreate(this.axMapControl1.Object);this.axMapControl1.CurrentTool=CmdasITool;同类的方法中用到此方法的还有以下等： 放大：ICommandCmd=newControlsMapZoomInTool();缩小：ControlsMapZoomOutToolCmd=newControlsMapZoomOutTool();漫游：ControlsMapPanToolCmd=newControlsMapPanTool();绘制矩形：ControlsNewRectangleToolCmd=newControlsNewRectangleTool();绘制圆：ControlsNewCircleToolCmd=newControlsNewCircleTool();绘制椭圆：ControlsNewEllipseToolCmd=newControlsNewEllipseTool();绘制曲线：ControlsNewCurveToolCmd=newControlsNewCurveTool();绘制直线：ControlsNewLineToolCmd=newControlsNewLineTool();绘制点标记：ControlsNewMarkerToolCmd=newControlsNewMarkerTool();流方法绘图：ControlsNewFreeHandToolCmd=newControlsNewFreeHandTool();墨水绘图：ControlsInkPenToolCmd=newControlsInkPenTool();ControlsInkGenericDrawToolCmd=newControlsInkGenericDrawTool();旋转工具：ControlsMapRotateToolCmd=newControlsMapRotateTool();旋转图形：ControlsRotateElementToolCmd=newControlsRotateElementTool();选择要素：ControlsSelectFeaturesToolCmd=newControlsSelectFeaturesTool();选择图形：ControlsSelectToolCmd=newControlsSelectTool();属性工具：ControlsMapIdentifyToolCmd=newControlsMapIdentifyTool();测量工具：ControlsMapMeasureToolCmd=newControlsMapMeasureTool();超链接工具：ControlsMapHyperlinkToolCmd=newControlsMapHyperlinkTool();B类：Command命令的实现，前面是Controls后面是CommandClass命令的都可以用这个程序示例：全图显示：ICommandCmd=newControlsMapFullExtentCommandClass();Cmd.OnCreate(this.axMapControl1.Object);Cmd.OnClick();类似可以实现的功能有：坐标查找：ICommandCmd=newControlsMapGoToCommand();查找命令：ICommandCmd=newControlsMapFindCommandClass();创建书签：ICommandCmd=newControlsMapCreateBookmarkCommandClass();墨迹设置：ICommandCmd=newControlsInkOptionsCommandClass();清楚旋转：ICommandCmd=newControlsMapClearMapRotationCommandClass();转到页底：ICommandCmd=newControlsMapPageDownCommandClass();转到页左：ICommandCmd=newControlsMapPageLeftCommandClass();转到页右：ICommandCmd=newControlsMapPageRightCommandClass();转到页上：ICommandCmd=newControlsMapPageUpCommandClass();向右：ICommandCmd=newControlsMapRightCommandClass();向上：ICommandCmd=newControlsMapUpCommandClass();中心放大：ICommandCmd=newControlsMapZoomInFixedCommandClass();中心缩小：ICommandCmd=newControlsMapZoomOutFixedCommandClass();后一视图：ICommandCmd=newControlsMapZoomToLastExtentBackCommandClass();前一视图：ICommandCmd=newControlsMapZoomToLastExtentForwardCommandClass();地方查找：ICommandCmd=newControlsMyPlacesCommandClass();打开文档：ICommandCmd=newControlsOpenDocCommandClass();撤销：ICommandCmd=newControlsRedoCommandClass();图形向左旋转：ICommandCmd=newControlsRotateLeftCommandClass();向右旋转：ICommandCmd=newControlsRotateRightCommandClass();文档另存为：ICommandCmd=newControlsSaveAsDocCommandClass();选择第一个图层中的所有元素：ICommandCmd=newControlsSelectAllCommandClass();选择屏幕中的所有部分：ICommandCmd=newControlsSelectScreenCommandClass();撤销命令：ICommandCmd=newControlsUndoCommandClass();缩放到被选择的部分：ICommandCmd=newControlsZoomToSelectedCommandClass();*补充：上面的某些功能的其他实现方法几个特殊的方法：privatevoid全图ToolStripMenuItem_Click(objectsender,EventArgse)this.axMapControl1.Extent=this.axMapControl1.FullExtent;privatevoid刷新ToolStripMenuItem_Click(objectsender,EventArgse)axMapControl1.Refresh();privatevoid中心放大ToolStripMenuItem_Click(objectsender,EventArgse)IEnvelopeobjEnvelope=null;objEnvelope=axMapControl1.Extent;objEnvelope.Expand(0.2,0.2,true);axMapControl1.Extent=objEnvelope;privatevoid中心缩小ToolStripMenuItem_Click(objectsender,EventArgse)IEnvelopeobjEnvelope=null;objEnvelope=axMapControl1.Extent;objEnvelope.Expand(2,2,true);axMapControl1.Extent=objEnvelope;privatevoid前一视图ToolStripMenuItem_Click(objectsender,EventArgse)IExtentStackpExtentStack=null;pExtentStack=axMapControl1.ActiveView.ExtentStack;if(pExtentStack.CanUndo()pExtentStack.Undo();axMapControl1.Refresh();privatevoid后一
