AutoCAD二次开发三种添加插件按钮的方法之二

上一篇相关文章主要借助了cuix配置文件来制作插件按钮，但是对于纯码农来说还是喜欢以代码来说话，今天这篇文章就来讲讲纯代码添加按钮。

开发IDE：VS2010

环境：.Net Framework4.0

AutoCAD版本：2014中/EN

今天介绍的代码主要借助的是AcCui.dll这个动态链接库，因为在我的了解中，CAD的开发库中有很多类似的类，又没有相关的介绍API的文档（你不是专业人员真是心累~），都是自己尝试或者在AutoDesk社区中找到的相关内容。

下面先说说思路，再添加核心代码，如果你有需要，欢迎关注我或者联系我，我很愿意与你共享资源与共同学习进步

。

1.首先还是要找到相关的主cuix文件，就是AutoCAD二次开发三种添加插件按钮的方法之一中介绍的acad.cuix文件（我觉得添加图片排版太不方便了，所以尽量减少图片~）；

//获取到ACAD.cuix
CustomizationSection cs = new CustomizationSection((string)Application.GetSystemVariable("MENUNAME"));
string strCurWorkspace = (string)Application.GetSystemVariable("WSCURRENT");
//workspace的操作
Workspace curWorkspace = cs.getWorkspace(strCurWorkspace);
if (IsExistPluginTab(ed, curWorkspace))//如果自定义工作空间存在指定的Tab
{
//初始化功能按钮
InitialRibbonBtn(ed, cs);
}

2.由于我们是需要将按钮添加到‘插件’这个Tab中，而这个Tab是在Ribbon中的（而AutoCAD又是可以自定义是否显示Ribbon的，而且不同的工作空间显示的Ribbon还不同，所以我这里尽量简化了，不讨论那些了），这个Tab的ElementID叫做RBN_00012112，我们可以根据此判断这个Tab是否存在还是被删掉了（默认安装时存在的）；这里只讨论存在的咯。

3.如果存在，我们直接获取到这个Tab，在其中在其中添加一个Panel按钮；

/// <summary>
/// 在acad.cuix中的(选项卡)Tab中添加panel
/// </summary>
/// <param name="cs">acad.cuix的引用</param>
/// <param name="tabName">Tab的中文名字</param>
/// <param name="tabEnName">Tab的英文版名称</param>
/// <param name="panelName">新建的Panel名称（自定义）</param>
/// <returns></returns>
private  Autodesk.AutoCAD.Customization.RibbonPanelSource AddRibbonPanelToTab(CustomizationSection cs, string tabName,string tabEnName, string panelName)
{
RibbonRoot root = cs.MenuGroup.RibbonRoot;
Autodesk.AutoCAD.Customization.RibbonPanelSourceCollection panels = root.RibbonPanelSources;
RibbonTabSource rts = root.FindTab("RBN_00012112");//ElementID
if (rts == null)
{
Application.DocumentManager.MdiActiveDocument.Editor.WriteMessage("未找到指定的插件Tab");
}
if (rts.Name == tabName || rts.Name == tabEnName)
{
//创建一个panel并添加到panels集合中
Autodesk.AutoCAD.Customization.RibbonPanelSource panelSrc = new Autodesk.AutoCAD.Customization.RibbonPanelSource(root);
panelSrc.Text = panelSrc.Name = panelName;
panelSrc.ElementID = panelSrc.Id = panelName + "_PanelSourceID";
panels.Add(panelSrc);

RibbonPanelSourceReference ribPanelSourceRef = new RibbonPanelSourceReference(rts);
ribPanelSourceRef.PanelId = panelSrc.ElementID;
rts.Items.Add(ribPanelSourceRef);

return panelSrc;
}
return null;
}

4.在这个自定义的Panel直接添加按钮，最后重新加载所有menu。

private void InitialRibbonBtn(Editor ed, CustomizationSection cs)
{
Autodesk.AutoCAD.Customization.RibbonPanelSource panelSrc = AddRibbonPanelToTab(cs, "插件", "Plug-ins","测试Panel");
MacroGroup macGroup = cs.MenuGroup.MacroGroups[0];
//int macroCount = cs.MenuGroup.MacroGroups.Count;
//foreach (MacroGroup macro in cs.MenuGroup.MacroGroups)
//{
//    string name = macro.Name;
//}
RibbonRow row = new RibbonRow();
panelSrc.Items.Add((Autodesk.AutoCAD.Customization.RibbonItem)row);

RibbonCommandButton button1 = new RibbonCommandButton(row);
button1.Text = "测试LargeBtn1";
MenuMacro menuMac1 = macGroup.CreateMenuMacro("Button1_Macro", "^C^CButton1_Command ", "Button1_Tag", "Button1_Help",
MacroType.Any, "RibbonImages//test16.png", "RibbonImages//test32.png", "Button1_Label_Id");
button1.MacroID = menuMac1.ElementID;
button1.ButtonStyle = RibbonButtonStyle.LargeWithText;
button1.KeyTip = "Button1 Key Tip";
button1.TooltipTitle = "Button1 Tooltip Title!";
row.Items.Add((Autodesk.AutoCAD.Customization.RibbonItem)button1);

RibbonCommandButton button2 = new RibbonCommandButton(row);
button2.Text = "测试SmallBtn1";
MenuMacro menuMac2 = macGroup.CreateMenuMacro("Button2_Macro", "^C^CButton2_Command ", "Button2_Tag", "Button2_Help",
MacroType.Any, "RibbonImages//test16.png", "RibbonImages//test32.png", "Button2_Label_Id");
button2.MacroID = menuMac2.ElementID;//ID不能少
button2.ButtonStyle = RibbonButtonStyle.SmallWithText;
button2.KeyTip = "Button2 Key Tip";
button2.TooltipTitle = "Button2 Tooltip Title!";
row.Items.Add((Autodesk.AutoCAD.Customization.RibbonItem)button2);

RibbonCommandButton button3 = new RibbonCommandButton(row);
button3.Text = "测试LargeBtn3";
MenuMacro menuMac3 = macGroup.CreateMenuMacro("Button3_Macro", "^C^CButton3_Command ", "Button3_Tag", "Button3_Help",
MacroType.Any, "RibbonImages//test16.png", "RibbonImages//test32.png", "Button3_Label_Id");
button3.MacroID = menuMac3.ElementID;
button3.ButtonStyle = RibbonButtonStyle.LargeWithText;
button3.KeyTip = "Button3 Key Tip";
button3.TooltipTitle = "Button3 Tooltip Title!";
row.Items.Add((Autodesk.AutoCAD.Customization.RibbonItem)button3);

cs.Save();

Application.ReloadAllMenus();//重加载所有的按钮
ed.WriteMessage("Add buttons successed!");
}

最后，效果和第一篇最后的效果是一样的哦！~
