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。
