基于C#的SolidWorks插件开发(2)--创建插件

在项目工程中可以看到SwAddin.cs文件。这个文件是插件的核心文件，包括插件的名称，注册表项，菜单，以及菜单的回调函数都在该文件中实现。

1.修改插件的名称和描述

Guid为插件生成后注册到注册表的项，由系统自动生成。

Description为插件的描述信息

Title为插件的名称。

修改完成，安装插件后会在注册表中看到如下信息

2.添加插件菜单

添加插件菜单项是在方法“AddCommandMgr()”中，示例代码如下：

public void AddCommandMgr()
        {
            if (iBmp == null)
                iBmp = new BitmapHandler();
            Assembly thisAssembly;
            int cmdIndex0, cmdIndex1;
            string Title = "PDM", ToolTip = "SolidWorks_PDM";
            ICommandGroup cmdGroup;
 
            int[] docTypes = new int[]{(int)swDocumentTypes_e.swDocASSEMBLY,
                                       (int)swDocumentTypes_e.swDocDRAWING,
                                       (int)swDocumentTypes_e.swDocPART};
 
            thisAssembly = System.Reflection.Assembly.GetAssembly(this.GetType());
 
            int cmdGroupErr = ;
            bool ignorePrevious = false;
 
            object registryIDs;
            //get the ID information stored in the registry
            bool getDataResult = iCmdMgr.GetGroupDataFromRegistry(mainCmdGroupID, out registryIDs);
 
            int[] knownIDs = new int[] { mainItemID1, mainItemID2 };
 
            if (getDataResult)
            {
                if (!CompareIDs((int[])registryIDs, knownIDs)) //if the IDs don't match, reset the commandGroup
                {
                    ignorePrevious = true;
                }
            }
 
            cmdGroup = iCmdMgr.CreateCommandGroup2(mainCmdGroupID, Title, ToolTip, "", , ignorePrevious, ref cmdGroupErr);//添加主菜单            cmdGroup.LargeIconList = iBmp.CreateFileFromResourceBitmap("SolidWorks_PDM.ToolbarLarge.bmp", thisAssembly);
            cmdGroup.SmallIconList = iBmp.CreateFileFromResourceBitmap("SolidWorks_PDM.ToolbarSmall.bmp", thisAssembly);
            cmdGroup.LargeMainIcon = iBmp.CreateFileFromResourceBitmap("SolidWorks_PDM.MainIconLarge.bmp", thisAssembly);
            cmdGroup.SmallMainIcon = iBmp.CreateFileFromResourceBitmap("SolidWorks_PDM.MainIconSmall.bmp", thisAssembly);
 
            int menuToolbarOption = (int)(swCommandItemType_e.swMenuItem | swCommandItemType_e.swToolbarItem);
            //cmdIndex0 = cmdGroup.AddCommandItem2("CreateCube", -1, "Create a cube", "Create cube", 0, "CreateCube", "", mainItemID1, menuToolbarOption);
            //cmdIndex1 = cmdGroup.AddCommandItem2("Show PMP", -1, "Display sample property manager", "Show PMP", 2, "ShowPMP", "EnablePMP", mainItemID2, menuToolbarOption);
 
            cmdIndex0 = cmdGroup.AddCommandItem2("自定义用户属性", , "填写自定义用户属性", "填写自定义用户属性", , "WriteAttribute","", mainItemID1, menuToolbarOption);//添加主菜单下的子菜单
            cmdIndex1 = cmdGroup.AddCommandItem2("写入PDM数据库", , "写入PDM数据库", "写入PDM数据库", , "FillSQL", "", mainItemID2, menuToolbarOption);//添加主菜单下的子菜单
            cmdGroup.HasToolbar = true;
            cmdGroup.HasMenu = true;
            cmdGroup.Activate();
 
            bool bResult;
 
            #region
            //FlyoutGroup flyGroup = iCmdMgr.CreateFlyoutGroup(flyoutGroupID, "Dynamic Flyout", "Flyout Tooltip", "Flyout Hint",
            //  cmdGroup.SmallMainIcon, cmdGroup.LargeMainIcon, cmdGroup.SmallIconList, cmdGroup.LargeIconList, "FlyoutCallback", "FlyoutEnable");
 
            //flyGroup.AddCommandItem("FlyoutCommand 1", "test", 0, "FlyoutCommandItem1", "FlyoutEnableCommandItem1");
 
            //flyGroup.FlyoutType = (int)swCommandFlyoutStyle_e.swCommandFlyoutStyle_Simple;
 
            foreach (int type in docTypes)
            {
                CommandTab cmdTab;
 
                cmdTab = iCmdMgr.GetCommandTab(type, Title);
 
                if (cmdTab != null & !getDataResult | ignorePrevious)//if tab exists, but we have ignored the registry info (or changed command group ID), re-create the tab.  Otherwise the ids won't matchup and the tab will be blank
                {
                    bool res = iCmdMgr.RemoveCommandTab(cmdTab);
                    cmdTab = null;
                }
 
                //if cmdTab is null, must be first load (possibly after reset), add the commands to the tabs
                if (cmdTab == null)
                {
                    cmdTab = iCmdMgr.AddCommandTab(type, Title);
 
                    CommandTabBox cmdBox = cmdTab.AddCommandTabBox();
 
                    int[] cmdIDs = new int[];
                    int[] TextType = new int[];
 
                    cmdIDs[] = cmdGroup.get_CommandID(cmdIndex0);
 
                    TextType[] = (int)swCommandTabButtonTextDisplay_e.swCommandTabButton_TextHorizontal;
 
                    cmdIDs[] = cmdGroup.get_CommandID(cmdIndex1);
 
                    TextType[] = (int)swCommandTabButtonTextDisplay_e.swCommandTabButton_TextHorizontal;
 
                    cmdIDs[] = cmdGroup.ToolbarId;
 
                    TextType[] = (int)swCommandTabButtonTextDisplay_e.swCommandTabButton_TextHorizontal | (int)swCommandTabButtonFlyoutStyle_e.swCommandTabButton_ActionFlyout;
 
                    bResult = cmdBox.AddCommands(cmdIDs, TextType);
 
                    //CommandTabBox cmdBox1 = cmdTab.AddCommandTabBox();
                    //cmdIDs = new int[1];
                    //TextType = new int[1];
 
                    //cmdIDs[0] = flyGroup.CmdID;
                    //TextType[0] = (int)swCommandTabButtonTextDisplay_e.swCommandTabButton_TextBelow | (int)swCommandTabButtonFlyoutStyle_e.swCommandTabButton_ActionFlyout;
 
                    //bResult = cmdBox1.AddCommands(cmdIDs, TextType);
 
                    //cmdTab.AddSeparator(cmdBox1, cmdIDs[0]);
 
                }
 
            }
            #endregion
            thisAssembly = null;
 
        }

添加完成之后运行程序即可看到刚刚添加的菜单项

3.回调函数

创建菜单后，由于没有给菜单绑定任何事件，单击不会产生任何效果。于是第二部要做的就是给自定义菜单添加事件，即回调函数。以菜单“自定义用户属性”为例，在添加菜单时有一个参数会指定其回调函数的函数名，如图5.2所示，该处利用反射机制在单击该菜单时调用具有该函数名的函数。

添加相应的回调函数事件

public void WriteAttribute()
        {
            //ITaskpaneView pTaskPanView;
            //pTaskPanView = iSwApp.CreateTaskpaneView2("", "自定义用户属性");
            Form1 TaskPanWinFormControl = new Form1();
            TaskPanWinFormControl.iSwApp = iSwApp;
            TaskPanWinFormControl.ShowDialog();
 
            //pTaskPanView.DisplayWindowFromHandle(TaskPanWinFormControl.Handle.ToInt64());
            //TaskPanUserControl = (UserControl1)pTaskPanView.GetControl();
            //Debug.Print(TaskPanUserControl.Name);
        }

运行程序，单击“自定义属性”，即可看到如下图所示的效果

这样，一个最简单的插件就完成了，最后将插件打包即可在安装有SolidWorks的计算机上使用。
