  • 基于sharpdevelop核心和ArcEngine打造插件式桌面GIS应用之四——工具栏

      系统演示请看《我的插件GIS系统演示

      今天来讲一下工具栏的设计,目前是完全按照Sharpdevelop(我把它简称为SD)的规则建立工具栏,讲的内容也完全是SD中如何定义工具栏,大家有兴趣的话也可以实现自己的工具栏加载机制,我现在在另一个项目中已经脱离SD,通过Sqlite数据库配置界面,实现了一个简单的插件框架。

      使用sharpdevelop的插件机制之后,工具栏的开发已经非常便捷,主要优点有:
      1、插件方式,装配、修改便捷
      由于SD的插件配置文件采用XML文件,便于阅读,我们可以根据自己的需求新建、修改配置信息。实现满足特定需求的工具栏。

      2、利用Condition实现条件可视化
      很多时候,工具栏按钮是否显示(Visible)、是否可用 (Enable)需要根据特定条件变化。SD框架设计了ICondition条件接口,通过实现该接口自定义类来完成条件可视化。

        <!--条件(单一条件),当前活动窗体是MapViewContent时显示-->
    <Condition name = "WindowActive" activewindow="GISP.Addin.ArcMap.Views.MapViewContent">
    <ToolbarItem id = "New" icon = "Icons.16x16.NewDocumentIcon" tooltip = "${res:XML.MainMenu.FileMenu.New.File.Description}" class = "GISP.Addin.ArcMap.Commands.NewMxdCommand"/>
    <ToolbarItem id="OpenMxd" tooltip="${res:GIS.MapControl.Commands.OpenMXD}" icon="Icons.16x16.OpenFileIcon" class="GISP.Addin.ArcMap.Commands.OpenMxdCommand"/>
    <ToolbarItem id="SaveMxd" tooltip="${res:GIS.MapControl.Commands.SaveMXD}" icon="Icons.16x16.SaveIcon" class="GISP.Addin.ArcMap.Commands.SaveMxdCommand"/>
    <ToolbarItem id="SaveAsMxd" tooltip="${res:GIS.MapControl.Commands.SaveAsMXD}" icon="Icons.16x16.SaveIcon" class="GISP.Addin.ArcMap.Commands.SaveMxdAsCommand"/>
    <ToolbarItem id = "Separator1" type = "Separator"/>
    <ToolbarItem id="ExportToPic" tooltip="输出图片" icon="ArcGIS.MapOpen16" class="GISP.Addin.ArcMap.Commands.ExportActiveViewToPictureCommand"/>
    </Condition>
    <!--复合条件-->
    <ComplexCondition>
    <Or>
    <Condition name="CADLayerTOCSelectItemConditionEvaluator" itemtype="null"/>
    <Condition name="CADLayerTOCSelectItemConditionEvaluator" itemtype="group"/>
    </Or>
    </ComplexCondition>

      条件分为单一条件和复合条件。
      复合条件的复合关系包括有:And和Or。
      条件的action状态分为不显示(不指定)和不可用(action="disable")。 

      3、工具栏的父对象灵活指定
      工具栏可的父对象一般是主窗体,也可以是子控件、子窗体,通过简单的代码就可以在不同级别的对象上建立工具栏。 
      如果要子子窗体或者空间上显示工具栏,只需要在代码中添加类似代码即可:

    public partial class CatalogControl : UserControl
    {

    ……
    ToolStrip toolStrip = null;

    #region 构造函数

    public CatalogControl()
    {
    InitializeComponent();
    InitControl();
         ……
    }

    #endregion

    private void InitControl()
    {
    toolStrip = ToolbarService.CreateToolStrip(this, "/SDF/Pads/ArcGIS/CatalogPad/Toolbar");
    toolStrip.GripStyle = ToolStripGripStyle.Hidden;
    this.Controls.Add(toolStrip);
    }

      

      接下来讲一下如何定义工具栏,以地图导航工具栏为例:
      1、首先定义工具栏按钮实现类
       

     1 /// <summary>
    2 /// 地图放大
    3 /// </summary>
    4 class MapZoomInCommand : BaseMapControlCommand
    5 {
    6 public override void Run()
    7 {
    8
    9 if (MapControl != null)
    10 {
    11 ESRI.ArcGIS.SystemUI.ICommand command = new ESRI.ArcGIS.Controls.ControlsMapZoomInToolClass();
    12 command.OnCreate(MapControl.MapControlDefault);
    13 MapControl.MapControlDefault.CurrentTool = command as ESRI.ArcGIS.SystemUI.ITool;
    14 StatusBarService.SetMessage("放大");
    15 }
    16 }
    17 }

      MapZoomInCommand的父类是BaseMapControlCommand,在内部封装了DM控件、TOC控件、PageLayout控件的属性,以便在子类中简化实现。

     1     public class BaseMapControlCommand : AbstractCommand
    2 {
    3
    4 protected DefaultMapControl MapControl
    5 {
    6 get
    7 {
    8 foreach (IViewContent view in WorkbenchSingleton.Workbench.ViewContentCollection)
    9 {
    10 if (view.Control is DefaultMapControl)
    11 return view.Control as DefaultMapControl;
    12 }
    13 return null;
    14 }
    15 }
    16
    17 protected DefaultPageLayoutControl PageLayoutControl
    18 {
    19 get
    20 {
    21 foreach (IViewContent view in WorkbenchSingleton.Workbench.ViewContentCollection)
    22 {
    23 if (view.Control is DefaultPageLayoutControl)
    24 return view.Control as DefaultPageLayoutControl;
    25 }
    26 return null;
    27 }
    28 }
    29
    30 protected TocControl TocControl
    31 {
    32 get
    33 {
    34 foreach (PadDescriptor pad in WorkbenchSingleton.Workbench.PadContentCollection)
    35 {
    36 if (pad.PadContent.Control is TocControl)
    37 return pad.PadContent.Control as TocControl;
    38 }
    39 return null;
    40 }
    41 }
    42
    43 public override void Run()
    44 {
    45
    46 }
    47 }
    
    
    

      2、定义Addin文件

      命令类定义好之后,就需要在Addin文件中进行配置。 

    <Path name="/SDF/Workbench/ToolBar/ArcMap_Navagation">
    <Condition name = "WindowActive" activewindow="GISP.Addin.ArcMap.Views.MapViewContent">
    <ToolbarItem id="ZoomIn" tooltip="${res:GIS.MapControl.Commands.ZoomIn}" icon="GIS.MapControl.ZoomIn" class="GISP.Addin.ArcMap.Commands.MapZoomInCommand"/>
    <ToolbarItem id="ZoomOut" tooltip="${res:GIS.MapControl.Commands.ZoomOut}" icon="GIS.MapControl.ZoomOut" class="GISP.Addin.ArcMap.Commands.MapZoomOutCommand"/>
    ...... 

      配置时需要指定ID、提示信息、图标和命令类。需要注意的是图标需要保存在资源文件中。

     

      3、 启动程序测试
        如果Addin文件没有书写错误,程序启动后,会生成如下图所示的工具栏。
     


    补充

      工具栏按钮的类型包括普通按钮和下拉按钮,普通按钮的定义上面已经进行了介绍,这里对下拉按钮做一个简单说明。

      下拉按钮的界面显示类似下图

      配置文件的格式如下代码,注意指定type = "DropDownButton",其下拉项是menuitem

    <ToolbarItem id      = "Editor" type = "DropDownButton" icon    = "ArcGIS.EditingLayerTarget16"
    tooltip
    = "编辑" class ="GISP.Addin.ArcMap.Commands.MapEditorDropDownList">
    <Condition name="MapContainsLayer" itemtype="ESRI.ArcGIS.Carto:ESRI.ArcGIS.Carto.IFeatureLayer" action="Disable">
    <Condition name = "EditState" state="notediting" action="Disable">
    <MenuItem id="StartEdit" label="启动编辑" icon="" class="GISP.Addin.ArcMap.Commands.MapStartEditingCommand"/>
    </Condition>
    <Condition name = "EditState" state="editing" action="Disable">
    <MenuItem id="StopEdit" label="停止编辑" icon="" insertafter="StartEdit" class="GISP.Addin.ArcMap.Commands.MapStopEditingCommand"/>
    <MenuItem id = "editStatusSeprator" type = "Separator" insertafter="StopEdit"/>
    <MenuItem id="saveEdit" label="保存编辑" icon="" insertafter="editStatusSeprator" class="GISP.Addin.ArcMap.Commands.MapSaveEditingCommand"/>
    <MenuItem id = "SaveEditSeprator" type = "Separator" insertafter="saveEdit"/>
    <MenuItem id="Edit_Move" label="移动.." icon="" insertafter="SaveEditSeprator" class="GISP.Addin.ArcMap.Commands.MapEdit_MoveFeatureCommand"/>
    <MenuItem id="Edit_Split" label="分解" icon="" insertafter="Edit_Move" class="GISP.Addin.ArcMap.Commands.MapEdit_SplitMultipleFeatureCommand"/>
    <MenuItem id="Edit_Buffer" label="缓冲..." icon="" insertafter="Edit_Split" class="GISP.Addin.ArcMap.Commands.MapEdit_BufferFeatureCommand"/>
    <MenuItem id="Edit_Union" label="合并..." icon="" insertafter="Edit_Buffer" class="GISP.Addin.ArcMap.Commands.MapEdit_MergeFeatureCommand"/>
    <MenuItem id="Edit_Intersect" label="交集" icon="" insertafter="Edit_Union" class="GISP.Addin.ArcMap.Commands.MapEdit_IntersectFeatureCommand"/>
    <!--<MenuItem id="SelectFeatures" label="求异" icon="" class="GISP.Addin.ArcMap.Commands.MapEdit_DifferenceFeatureCommand"/>-->
    <MenuItem id="Edit_Cut" label="裁剪..." icon="" insertafter="Edit_Intersect" class="GISP.Addin.ArcMap.Commands.MapEdit_ClipFeatureCommand"/>
    <MenuItem id="Edit_AddIntersectPointOfLine" label="添加交点..." insertafter="Edit_Cut" icon="" class="GISP.Addin.ArcMap.Commands.MapEdit_AddIntersectPointOfPolyLineFeatureCommand"/>
    <MenuItem id="Edit_GeneralizeGeometry" label="一般化..." icon="AddIntersectPointOfLine" insertafter="Edit_AddIntersectPointOfLine" class="GISP.Addin.ArcMap.Commands.MapEdit_GeneralizeGeometryCommand"/>
    <MenuItem id="Edit_DeleteOverlap" label="删除压盖要素..." icon="" insertafter="Edit_AddIntersectPointOfLine" class="GISP.Addin.ArcMap.Commands.MapEdit_DeleteOverlapFeaturesCommand"/>
    </Condition>
    </Condition>
    </ToolbarItem>
