Qt中使用QAxObject的dynamicCall和querySubObject函数操作SolidWorks的方法

　　大部分函数可以直接从VB语言“翻译”过去成为Qt中的C++语言，如

    Set Part = swApp.OpenDoc6(strFilePath & "\" & partName & ".SLDPRT", 1, 0, "", longstatus, longwarnings) '打开指定文件，这里是SLDPRT格式三维模型
    
    Set Part = swApp.ActivateDoc2(partName & ".SLDPRT", False, longstatus) '设置文件处于激活状态

 　　翻译到Qt就是

        Part = swApp->querySubObject("OpenDoc(QString,int)",path,1);
        Part = swApp->querySubObject("ActivateDoc(QString)",this->partName);

　　这里不用OpenDoc6是为了简便。这里的数据类型都是string, int 这样子的常规类型

　　但是有一种问题，就是这样的VB语言，比如SelectByID2

	boolstatus = Part.Extension.SelectByID2("MainRad@草图[email protected]", "DIMENSION", 1.52752972114265E-02, -1.13202148822171E-03, 2.30092248393811E-02, False, 0, Nothing, 0)

Visual Basic (Usage)
Dim instance As IModelDocExtension Dim Name As String Dim Type As String Dim X As Double Dim Y As Double Dim Z As Double Dim Append As Boolean Dim Mark As Integer Dim Callout As Callout Dim SelectOption As Integer Dim value As Boolean   value = instance.SelectByID2(Name, Type, X, Y, Z, Append, Mark, Callout, SelectOption)

 

C++/CLI
bool SelectByID2( &   String^ Name, &   String^ Type, &   double X, &   double Y, &   double Z, &   bool Append, &   int Mark, &   Callout^ Callout, &   int SelectOption )

　　这里面有一个Callout的指针，在Qt里面用

        myExtension->dynamicCall(
                    "SelectByID2(QString,QString,double,double,"
                    "double,bool,int,Callout *,int)",list);

　　会提醒参数不匹配，这里要用QAxObject的asVariant()方法来解决，就是说，list里面对应append一个QAxObject*类型的参数

	list.append(myExtension->asVariant());

　　然后dynamicCall里面把Callout * 改成QAxObject *类型，就可以了

 

        myExtension->dynamicCall(
                    "SelectByID2(QString,QString,double,double,"
                    "double,bool,int,QAxObject *,int)",list);

　　接下来就是EditDimensionProperties２函数，这个直接翻译就可以了

 

        Part->dynamicCall("EditDimensionProperties2(int,double,double,"
                          "QString,QString,bool,int,int,bool,int,int,"
                          "QString,QString,bool,QString,QString,bool)",list1);
