1、CommandUIs部分
这部分主要是定义承载Command和Tool的具体UI。如下图所示。
以CommandUI结尾的这几个类都是继承了Framework.Engine里面的ICommandUI接口，这样我们定义的Command和Tool就可以和这些UI绑定到一起了。
其中BarButtonItemCommandUI是DEV库中普通的按钮，BarCheckItemCommandUI是DEV库中由选中状态的按钮，MenuItemCommandUI是菜单按钮，一般右键菜单项会用这个UI，ToolStripMenuItemCommandUI是Winform下右键菜单项，在TocControl图层树中的右键菜单会采用这个按钮项。
2、Controls部分
3、常用命令和工具
public class MapZoomInTool : MapTool { private readonly ESRI.ArcGIS.SystemUI.ITool _EsriTool = null; public MapZoomInTool(MapApplication pMapApplication) : base(pMapApplication) { this._EsriTool = new ControlsMapZoomInToolClass(); this.SetIcon(CommandIconSize.IconSize16, "MapTools/Res/MapZoomIn16.png"); } /// <summary> /// 激活执行的函数 /// </summary> public override void OnActive() { base.OnActive(); (this._EsriTool as ESRI.ArcGIS.SystemUI.ICommand).OnCreate(this.MapApplication.ActiveControl); this.MapApplication.ActiveControl.CurrentTool = this._EsriTool; } /// <summary> /// 工具失活执行的函数 /// </summary> public override void OnDeActivate() { base.OnDeActivate(); this.MapApplication.ActiveControl.CurrentTool = null; } /// <summary> /// 鼠标按下执行的函数 /// </summary> /// <param name="button"></param> /// <param name="shift"></param> /// <param name="x"></param> /// <param name="y"></param> public override void OnMouseDown(int button, int shift, int x, int y) { if (button == 4) { this.MapApplication.AxControlPan(); } base.OnMouseDown(button, shift, x, y); } }
这就意味着，只要继承实现了MapApplication这个类，就可以直接使用该工具。例如我们的系统首页，定义了一个MapApplication实例，那么可以在此基础上初始化地图放大工具。
我们系统里面其他功能也要用这个工具的时候，也可以初始化一个MapApplication，或者实现一个继承MapApplication的类。例如系统中的出图模板设计功能。
这个功能里面，我们继承MapApplication，定义了LayoutDesignApplication。如下图所示。
public class LayoutDesignApplication : MapApplication { /// <summary> /// 版式设计主程序类 /// </summary> /// <param name="pAxMapControl"></param> /// <param name="pAxPageLayoutControl"></param> public LayoutDesignApplication(AxMapControl pAxMapControl, AxPageLayoutControl pAxPageLayoutControl) : base(pAxMapControl, pAxPageLayoutControl) { this.LayoutDesign = new LayoutDesign(); } /// <summary> /// 当前打开的 模板文件路径 /// </summary> public string ShmFilePath { get; set; } = ""; /// <summary> /// 版式设计对象 /// </summary> public LayoutDesign LayoutDesign { get; private set; } = null; /// <summary> /// 当前打开地图的元数据 /// </summary> public GeoChemMetaData GeoChemMetaData { get; private set; } /// <summary> /// 得到页面布局对象 /// </summary> public IPageLayout PageLayout { get { return this.PageLayoutControl.PageLayout; } } /// <summary> /// 加载属性面板的UI /// </summary> public Border PropertyBorder { get; set; } = null; }
添加工具的代码如下。
this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new OpenMxdCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new OpenShmCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new AddDataCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new SaveShmCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new SaveAsShmCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new MapFrameCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new MapGridCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new ResTableCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new ClassTableCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new ClassHistogramCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new HistogramMapCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new NorthArrowCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new ScaleBarCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new LegendCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new TitleCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new PointTextTool(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new PictureCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new NeatlineItemCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); SelectTool myPLDSelectTool = new SelectTool(this._LayoutDesignAplication); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(myPLDSelectTool)); this._LayoutDesignAplication.SelectTool = myPLDSelectTool; this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new PageZoomInTool(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new PageZoomOutTool(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new PagePanTool(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new PageZoomInFixedCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new PageZoomOutFixedCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new PageZoomWholePageCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new PageZoom100PercentCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new PageZoomBackCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new PageZoomForwardCommand(this._LayoutDesignAplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new ViewExportPicCommand(this._LayoutDesignAplication)));
再例如，布点的这个模块。
我们继承MapApplication定义了DeployApplication，如下图所示。
public class DeployApplication : MapApplication { private Project _Project = null; private object _SelectObjectOnProjectTree = null; private IFeature _SelectPointFeature = null; /// <summary> /// 采样点布置主App /// </summary> /// <param name="pAxMapControl"></param> /// <param name="pAxPageLayoutControl"></param> public DeployApplication(AxMapControl pAxMapControl, AxPageLayoutControl pAxPageLayoutControl) : base(pAxMapControl, pAxPageLayoutControl) { this.EngineEditor = new EngineEditorClass(); } /// <summary> /// ArcEngine编辑类 /// </summary> public EngineEditorClass EngineEditor { get; private set; } /// <summary> /// 当前工程对象 /// </summary> public Project Project { get { return this._Project; } set { this._Project = value; this.OnProjectChanged?.Invoke(this, new EventArgs()); } } /// <summary> /// 得到或设置树上选择的对象 /// </summary> public object SelectObjectOnWorkZoneTree { get { return this._SelectObjectOnProjectTree; } set { this._SelectObjectOnProjectTree = value; this.OnSelectObjectOnProjectTreeChanged?.Invoke(this, new EventArgs()); } } /// <summary> /// 得到或设置当前选中的采样点要素 /// </summary> public IFeature SelectPointFeature { get { return this._SelectPointFeature; } set { this._SelectPointFeature = value; this.OnSelectPointFeatureChanged?.Invoke(this, new EventArgs()); } } /// <summary> /// 触发Map25Sheet信息变化事件 /// </summary> public void FireMap25SheetInfoChangedEvent() { this.OnMap25SheetInfoChanged?.Invoke(this, new EventArgs()); } /// <summary> /// 当工程发生变化触发的事件 /// </summary> public event EventHandler<EventArgs> OnProjectChanged; /// <summary> /// 当在树上选中的对象发生变化触发的事件 /// </summary> public event EventHandler<EventArgs> OnSelectObjectOnProjectTreeChanged; /// <summary> /// 当选择的采样点元素发生变化触发的事件 /// </summary> public event EventHandler<EventArgs> OnSelectPointFeatureChanged; /// <summary> /// 当Map25Sheet的信息发生变化后触发的函数 /// </summary> public event EventHandler<EventArgs> OnMap25SheetInfoChanged; }
添加工具如下。
//初始化Application this._DeployApplication = new DeployApplication(myAxMapControl, myAxPageLayoutControl); this._DeployApplication.MainWindow = this; this._DeployApplication.OnProjectChanged += Application_OnWorkZoneChanged; this._DeployApplication.OnSelectObjectOnProjectTreeChanged += _Application_OnSelectObjectOnWorkZoneTreeChanged; this._DeployApplication.OnSelectPointFeatureChanged += Application_OnSelectPointFeatureChanged; this._DeployApplication.OnMap25SheetInfoChanged += Application_OnMap25SheetInfoChanged; this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new ProjectNewCommand(this._DeployApplication))); ProjectOpenCommand myWorkZoneOpenCommand = new ProjectOpenCommand(this._DeployApplication); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(myWorkZoneOpenCommand)); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new FrameworkUI.Files.AddDataCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new FrameworkUI.MapTools.MapZoomInTool(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new FrameworkUI.MapTools.MapZoomOutTool(this._DeployApplication))); FrameworkUI.MapTools.MapPanTool myMapPanTool = new FrameworkUI.MapTools.MapPanTool(this._DeployApplication); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(myMapPanTool)); this._DeployApplication.CrruteTool = myMapPanTool; this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new FrameworkUI.MapTools.MapZoomInFixedCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new FrameworkUI.MapTools.MapZoomOutFixedCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new FrameworkUI.MapTools.MapFullExtentCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new FrameworkUI.MapTools.MapZoomBackCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new FrameworkUI.MapTools.MapZoomForwardCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new FrameworkUI.MapTools.MeasureTool(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new Map5SheetSelectTool(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new FrameworkUI.MapTools.FeaturesClearSelectCommand(this._DeployApplication) { Caption = "Clear Select" })); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new MapSheetLabelCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new SamplePointLabelCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new Map5TerrainViewCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new Map25AutoPointCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new Map25ClearPointCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new EditorStartCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new EditorEditTool(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarCheckItemCommandUI(new EditorNewPointTool(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new EditorSaveCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new EditorStopCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarItemLinkSeparator()); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new Map25LoadUnitCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new Map25EncodeCommand(this._DeployApplication))); this.UI_Tool_Bar.Items.Add(new BarButtonItemCommandUI(new Map25ExportCommand(this._DeployApplication)));
