AutoCAD .Net 创建Ribbon界面(一)

从 AutoCAD 2010 版开始，引入了 Ribbon 界面。
那怎样用代码创建 Ribbon 界面呢？
本篇文章讲解如何创建如下图所示的 Ribbon Tab 页：测试Ribbon页。

如上图所示：
AutoCAD 的 Ribbon 界面由一系列 Tab 组成：默认、插入、注释……
测试Ribbon页 是我们创建的 Tab 页。
它由两个 Panel 组成：Panel1、Panel2。
Panel 下面就是三个按钮：直线、圆、Test。

除了需要添加 AutoCAD 引用： acmgd、acdbmgd、accoremgd(AutoCAD 2012版本及后续版本)。
还需要添加如下 AutoCAD 引用：
* AcWindows
* AdWindows

using System;using System.Collections.Generic;using System.Text;using Autodesk.AutoCAD.Runtime;using Autodesk.AutoCAD.ApplicationServices;using Autodesk.AutoCAD.DatabaseServices;using Autodesk.AutoCAD.Geometry;using Autodesk.AutoCAD.EditorInput;using Autodesk.AutoCAD.Ribbon;using Autodesk.Windows;//-----------------------------------------------private static RibbonTab myRibbonTab = null;[CommandMethod("MyRibbonTab")]public static void MyRibbonTab(){    // 创建Ribbon Tab页    if (myRibbonTab == null)    {        myRibbonTab = new RibbonTab();        myRibbonTab.Title = "测试Ribbon页";        myRibbonTab.Id = "MyRibbonTab";        //        RibbonPanel panel1 = new RibbonPanel();        RibbonPanelSource panel1Src = new RibbonPanelSource();        panel1Src.Title = "Panel 1";        panel1.Source = panel1Src;        myRibbonTab.Panels.Add(panel1);        RibbonButton rbnBtnLine = NewRibbonBtn("直线");        panel1Src.Items.Add(rbnBtnLine);        RibbonButton rbnBtnCircle = NewRibbonBtn("圆");        panel1Src.Items.Add(rbnBtnCircle);        //        RibbonPanel panel2 = new RibbonPanel();        RibbonPanelSource panel2Src = new RibbonPanelSource();        panel2Src.Title = "Panel 2";        panel2.Source = panel2Src;        myRibbonTab.Panels.Add(panel2);        RibbonButton rbnBtnTest = NewRibbonBtn("Test");        panel2Src.Items.Add(rbnBtnTest);    }    // 在AutoCAD的Ribbon窗口中显示    RibbonControl ribCntrl = RibbonServices.RibbonPaletteSet.RibbonControl;    ribCntrl.Tabs.Add(myRibbonTab);}private static RibbonButton NewRibbonBtn(string text){    RibbonButton button = new RibbonButton();    button.Text = text;    button.ShowText = true;    return button;}

以 AutoCAD 2014 版本为例，以上代码编译时会报错，添加如下引用即可解决。
* WindowsBase
* PresentationCore
* PresentationFramework
* System.Xaml

以上部分，只是实现了 Ribbon 界面，但 Ribbon 按钮还没实现触发执行命令。
首先，我们实现一自定义类 AdskCommandHandler，通过该类关联 Ribbon 按钮和对应的命令。

using Autodesk.AutoCAD.ApplicationServices.Core;using Autodesk.Windows;using System;using System.Threading;using System.Windows.Input;//namespace HelloAcad2014//{    public class AdskCommonHandler : ICommand    {        public event EventHandler CanExecuteChanged;        public bool CanExecute(object parameter)        {            return true;        }        public void Execute(object parameter)        {            RibbonButton button = parameter as RibbonButton;            if (button != null)            {                Application.DocumentManager.MdiActiveDocument.SendStringToExecute(                    (string)button.CommandParameter, true, false, true);            }        }    }//}

然后，更改 MyRibbonTab 代码如下：

using System;using System.Collections.Generic;using System.Text;using Autodesk.AutoCAD.Runtime;using Autodesk.AutoCAD.ApplicationServices;using Autodesk.AutoCAD.DatabaseServices;using Autodesk.AutoCAD.Geometry;using Autodesk.AutoCAD.EditorInput;using Autodesk.AutoCAD.Ribbon;using Autodesk.Windows;//-----------------------------------------------private static RibbonTab myRibbonTab = null;[CommandMethod("MyRibbonTab")]public static void MyRibbonTab(){    // 创建Ribbon Tab页    if (myRibbonTab == null)    {        myRibbonTab = new RibbonTab();        myRibbonTab.Title = "测试Ribbon页";        myRibbonTab.Id = "MyRibbonTab";        //        RibbonPanel panel1 = new RibbonPanel();        RibbonPanelSource panel1Src = new RibbonPanelSource();        panel1Src.Title = "Panel 1";        panel1.Source = panel1Src;        myRibbonTab.Panels.Add(panel1);        RibbonButton rbnBtnLine = NewRibbonBtn("直线", "line ");        panel1Src.Items.Add(rbnBtnLine);        RibbonButton rbnBtnCircle = NewRibbonBtn("圆", "circle ");        panel1Src.Items.Add(rbnBtnCircle);        //        RibbonPanel panel2 = new RibbonPanel();        RibbonPanelSource panel2Src = new RibbonPanelSource();        panel2Src.Title = "Panel 2";        panel2.Source = panel2Src;        myRibbonTab.Panels.Add(panel2);        RibbonButton rbnBtnTest = NewRibbonBtn("Test", "MyCmdTest ");        panel2Src.Items.Add(rbnBtnTest);    }    // 在AutoCAD的Ribbon窗口中显示    RibbonControl ribCntrl = RibbonServices.RibbonPaletteSet.RibbonControl;    bool isShow = false;    foreach (RibbonTab rbnTab in ribCntrl.Tabs)    {        if (rbnTab == myRibbonTab)        {            isShow = true;            break;        }    }    if (!isShow)    {        ribCntrl.Tabs.Add(myRibbonTab);    }}[CommandMethod("MyCmdTest")]public static void MyCmdTest(){    Document doc = Application.DocumentManager.MdiActiveDocument;    doc.Editor.WriteMessage("www.caxdev.com\n");}private static RibbonButton NewRibbonBtn(string text, string cmd){    RibbonButton button = new RibbonButton();    button.Text = text;    button.ShowText = true;    button.CommandHandler = new AdskCommonHandler();    button.CommandParameter = cmd;    return button;}

注意：
RibbonButton 的 CommandParameter 一定要在命令字符串最后加空格。
