使用CUIx加载Ribbon和传统菜单

CUIx是AutoCAD加载UI元素（包括Ribbon、传统菜单、工具条等）的最佳方式，它可以将所有UI元素打包至CUIx文件，在程序中直接加载即可。

采用代码动态创建UI元素，会存在一些问题：①如果其它插件采用CUIx后加载UI，将覆盖先前程序加载的UI；②传统菜单只能依靠COM编程方式加载。

创建CUIx文件和UI元素的通用函数

通过以下函数可以生成CUIx文件，并制作相应的命令宏和传统菜单。

可以不用代码制作Ribbon菜单，而是后期加载CUIx文件后在AutoCAD中以可视化的方式制作Ribbon菜单。

public static class CUITools {
    // 创建CUIx文件
    public static CustomizationSection AddCui(this Document doc, string cuiFile, string menuGroupName) {
        CustomizationSection cs;
        if (!File.Exists(cuiFile)) {
            cs = new CustomizationSection
            {
                MenuGroupName = menuGroupName
            };
            cs.SaveAs(cuiFile);
        }
        else cs = new CustomizationSection(cuiFile);
        return cs;
    }

    // 为CUIx文件添加命令宏
    public static MenuMacro AddMacro(this CustomizationSection cs, string name, string command, string tag, string helpString, string imagePath) {
        MenuGroup menuGroup = cs.MenuGroup;
        MacroGroup mg = menuGroup.FindMacroGroup(menuGroup.Name);
        if (mg == null) mg = new MacroGroup(menuGroup.Name, menuGroup);
        foreach (MenuMacro macro in mg.MenuMacros) {
            if (macro.ElementID == tag) return null;
        }
        MenuMacro menuMacro = new MenuMacro(mg, name, command, tag);
        menuMacro.macro.HelpString = helpString;
        if (!string.IsNullOrWhiteSpace(imagePath) && File.Exists(imagePath))
            menuMacro.macro.LargeImage = menuMacro.macro.SmallImage = imagePath;
        return menuMacro;
    }

    // 为CUIx文件添加传统菜单
    public static PopMenu AddPopMenu(this MenuGroup menuGroup, string name, StringCollection aliasList, string tag) {
        PopMenu pm = null;
        if (menuGroup.PopMenus.IsNameFree(name)) pm = new PopMenu(name, aliasList, tag, menuGroup);
        return pm;
    }

    // 为传统菜单添加菜单项
    public static PopMenuItem AddMenuItem(this PopMenu parentMenu, int index, string name, string macroId) {
        PopMenuItem newPmi = null;
        foreach (PopMenuItem pmi in parentMenu.PopMenuItems)
            if (pmi.Name == name) return newPmi;
        newPmi = new PopMenuItem(parentMenu, index);
        if (name != null) newPmi.Name = name;
        newPmi.MacroID = macroId;
        return newPmi;
    }

    // 为传统菜单添加子菜单
    public static PopMenu AddSubMenu(this PopMenu parentMenu, int index, string name, string tag) {
        PopMenu pm = null;
        if (parentMenu.CustomizationSection.MenuGroup.PopMenus.IsNameFree(name)) {
            pm = new PopMenu(name, null, tag, parentMenu.CustomizationSection.MenuGroup);
            PopMenuRef menuRef = new PopMenuRef(pm, parentMenu, index);
        }
        return pm;
    }

    // 为传统菜单添加分隔符
    public static PopMenuItem AddSeparator(this PopMenu parentMenu, int index) {
        return new PopMenuItem(parentMenu, index);
    }
}

通用函数创建CUIx文件和UI元素实例

调用下面的函数，可以生成mycuix.cuix文件：

public static void CreateCuix(){
	var doc=AcadApp.DocumentManeger.MdiActiveDocument;
	// 创建新的CUIx文件
	string cuixPath=@"C:\mycuix.cuix";
	var cs=doc.AddCui(cuixPath,"mycuix");
	// 定义命令宏
	cs.AddMacro("命令1","Cmd1",imagePath:@"res\Images\icon1.png");
	cs.AddMacro("命令2","Cmd2",imagePath:@"res\Images\icon2.png");
	cs.AddMacro("命令3","Cmd3",imagePath:@"res\Images\icon3.png");
	// 添加传统菜单
	var popmenu1=cs.MenuGroup.AddPopMenu("测试",new StringCollection(){"myPopMenu1"},"ID_MYPOPMENU1");
	if(popmenu1!=null){
		popmenu1.AddMenuItem(-1,"命令1","Cmd1");
		popmenu1.AddMenuItem(-1,"命令2","Cmd2");
		popmenu1.AddMenuItem(-1,"命令3","Cmd3");
	}
	cs.Save();
}

在AutoCAD中调用cuiload命令可以选择加载该文件，进而可视化制作Ribbon菜单：

当然，也可以封装自动创建Ribbon的函数，这是与代码动态创建Ribbon别无二致。
