qt dumpcpp

The dumpcpp Tool (ActiveQt)

The dumpcpp tool generates a C++ namespace for a type library.

To generate a C++ namespace for a type library, call dumpcpp with the following command line parameters:

Option	Result
input	Generate documentation for input. input can specify a type library file or a type library ID, or a CLSID or ProgID for an object
-o file	Writes the class declaration to file.h and meta object infomation to file.cpp
-n namespace	Generate a C++ namespace namespace
-nometaobject	Do not generate a .cpp file with the meta object information. The meta object is then generated in runtime.
-getfile libid	Print the filename for the typelibrary libid to stdout
-compat	Generate namespace with dynamicCall-compatible API
-v	Print version information
-h	Print help

dumpcpp can be integrated into the qmake build system. In your .pro file, list the type libraries you want to use in the TYPELIBS variable:

TEMPLATE = app TARGET = qutlook CONFIG += qaxcontainer TYPELIBS = $$system(dumpcpp -getfile {00062FFF-0000-0000-C000-000000000046})

The generated namespace will declare all enumerations, as well as one subclass for each coclass and interface declared in the type library. coclasses marked with the control attribute will be wrapped by a subclass.

Those classes that wrap creatable coclasses (i.e. coclasses that are not marked as noncreatable) have a default constructor; this is typically a single class of type Application.

Outlook::Application *outlook = new Outlook::Application;

All other classes can only be created by passing an IDispatch interface pointer to the constructor; those classes should however not be created explicitly. Instead, use the appropriate API of already created objects.

Outlook::_NameSpace *session = outlook->Session();

All coclass wrappers also have one constructors taking an interface wrapper class for each interface implemented.

Outlook::NameSpace *session = outlook->Session();

You have to create coclasses to be able to connect to signals of the subobject. Note that the constructor deletes the interface object, so the following will cause a segmentation fault:

Outlook::_NameSpace *tmp = outlook->Session(); Outlook::NameSpace *session = new Outlook::NameSpace(tmp); delete tmp; // or any other use of tmp: segfault

If the return type is of a coclass or interface type declared in another type library you have to include the namespace header for that other type library before including the header for the namespace you want to use (both header have to be generated with this tool).

By default, methods and property returning subobjects will use the type as in the type library. The caller of the function is responsible for deleting or reparenting the object returned. If the -compat switch is set, properties and method returning a COM object have the return type IDispatch*, and the namespace will not declare wrapper classes for interfaces.

In this case, create the correct wrapper class explicitly:

Outlook::NameSpace *session = new Outlook::NameSpace(outlook->Session());

You can of course use the IDispatch* returned directly, in which case you have to call Release() when finished with the interface.

All classes in the namespace are tagged with a macro that allows you to export or import them from a DLL. To do that, declare the macro to expand to __declspec(dllimport/export) before including the header file.

To build the tool you must first build the library. Then run your make tool in tools/dumpcpp.

经过试验，需要自己执行dumpcpp {00062FFF-0000-0000-C000-000000000046}生成.h和.cpp文件。
