ArcObjects SDK开发 022 开发框架搭建-FrameWorkUI包设计

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

主要定义了常用的UI。如下图所示。

3、常用命令和工具

我们看下最常用的地图放大工具的定义。

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");
    }

    /// 
    /// 激活执行的函数
    /// 
    public override void OnActive()
    {
        base.OnActive();
        (this._EsriTool as ESRI.ArcGIS.SystemUI.ICommand).OnCreate(this.MapApplication.ActiveControl);
        this.MapApplication.ActiveControl.CurrentTool = this._EsriTool;
    }

    /// 
    /// 工具失活执行的函数
    /// 
    public override void OnDeActivate()
    {
        base.OnDeActivate();
        this.MapApplication.ActiveControl.CurrentTool = null;
    }

    /// 
    /// 鼠标按下执行的函数
    /// 
    /// 
    /// 
    /// 
    /// 
    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。

ArcObjects SDK开发 022 开发框架搭建-FrameWorkUI包设计插图5

这个功能里面,我们继承MapApplication,定义了LayoutDesignApplication。如下图所示。

public class LayoutDesignApplication : MapApplication
{
    /// 
    /// 版式设计主程序类
    /// 
    /// 
    /// 
    public LayoutDesignApplication(AxMapControl pAxMapControl, AxPageLayoutControl pAxPageLayoutControl)
        : base(pAxMapControl, pAxPageLayoutControl)
    {
        this.LayoutDesign = new LayoutDesign();
    }

    /// 
    /// 当前打开的 模板文件路径
    /// 
    public string ShmFilePath { get; set; } = "";

    /// 
    /// 版式设计对象
    /// 
    public LayoutDesign LayoutDesign { get; private set; } = null;

    /// 
    /// 当前打开地图的元数据
    /// 
    public GeoChemMetaData GeoChemMetaData { get; private set; }

    /// 
    /// 得到页面布局对象
    /// 
    public IPageLayout PageLayout
    {
        get
        {
            return this.PageLayoutControl.PageLayout;
        }
    }
    /// 
    /// 加载属性面板的UI
    /// 
    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;

    /// 
    /// 采样点布置主App
    /// 
    /// 
    /// 
    public DeployApplication(AxMapControl pAxMapControl, AxPageLayoutControl pAxPageLayoutControl)
        : base(pAxMapControl, pAxPageLayoutControl)
    {
        this.EngineEditor = new EngineEditorClass();
    }

    /// 
    /// ArcEngine编辑类
    /// 
    public EngineEditorClass EngineEditor { get; private set; }

    /// 
    /// 当前工程对象
    /// 
    public Project Project
    {
        get
        {
            return this._Project;
        }
        set
        {
            this._Project = value;
            this.OnProjectChanged?.Invoke(this, new EventArgs());
        }
    }

    /// 
    /// 得到或设置树上选择的对象
    /// 
    public object SelectObjectOnWorkZoneTree
    {
        get { return this._SelectObjectOnProjectTree; }
        set
        {
            this._SelectObjectOnProjectTree = value;
            this.OnSelectObjectOnProjectTreeChanged?.Invoke(this, new EventArgs());
        }
    }

    /// 
    /// 得到或设置当前选中的采样点要素
    /// 
    public IFeature SelectPointFeature
    {
        get
        {
            return this._SelectPointFeature;
        }
        set
        {
            this._SelectPointFeature = value;
            this.OnSelectPointFeatureChanged?.Invoke(this, new EventArgs());
        }
    }

    /// 
    /// 触发Map25Sheet信息变化事件
    /// 
    public void FireMap25SheetInfoChangedEvent()
    {
        this.OnMap25SheetInfoChanged?.Invoke(this, new EventArgs());
    }

    /// 
    /// 当工程发生变化触发的事件
    /// 
    public event EventHandler OnProjectChanged;

    /// 
    /// 当在树上选中的对象发生变化触发的事件
    /// 
    public event EventHandler OnSelectObjectOnProjectTreeChanged;

    /// 
    /// 当选择的采样点元素发生变化触发的事件
    /// 
    public event EventHandler OnSelectPointFeatureChanged;

    /// 
    /// 当Map25Sheet的信息发生变化后触发的函数
    /// 
    public event EventHandler OnMap25SheetInfoChanged;
}

添加工具如下。
