如何使用 activeqt 的派生接口？
我认为 COM 中有一个相当简单的接口。我想在activeqt中实现它。我能够让 ATL 原型工作，但我宁愿使用 qt 小部件和信号而不是 COM 控件。
我可以在python的comtypes中加载ATL COM dll并运行help(ATLDll)，并且接口的相关扩展是
Methods inherited from comtypes.gen.<guid>.ITest:
Init(...)
method Init
我不确定如何在activeqt中获得相同的东西。 ATL正在使用这段代码来定义接口（我认为，这是在自动生成的_i.h文件中）：
MIDL_INTERFACE(<guid>)
ITest : public IDispatch
{
public:
virtual /* [helpstring][id] */ HRESULT STDMETHODCALLTYPE Init(
/* [in] */ IDispatch *obj) = 0;
};
然后类定义继承自我
public IDispatchImpl<ITest>
尝试混合activeqt和ATL，但到目前为止我还没有成功。我应该改用 dumpcpp 吗？ [edit] 如果您想从 Qt 调用现有的 COM 对象，dumpcpp 很有用，但无助于提取在 activeQt 中使用的接口。[/edit] 这是重写不混合ATL和activeqt的界面？我想知道 qt 工具和 ATL 都试图生成 idl 是否是我挣扎的根源......
谢谢！
I've got what I think is a fairly simple interface in COM. I would like to implement it in activeqt. I am able to get an ATL prototype to work, but I would rather use qt widgets and signals than COM controls.
I can load the ATL COM dll in python's comtypes and run help(ATLDll), and the relevant extension to the interface is
Methods inherited from comtypes.gen.<guid>.ITest:
Init(...)
method Init
I'm not sure how to get the same thing in activeqt. ATL is using this code to define the interface (I think, this is in the automatically generated _i.h file):
MIDL_INTERFACE(<guid>)
ITest : public IDispatch
{
public:
virtual /* [helpstring][id] */ HRESULT STDMETHODCALLTYPE Init(
/* [in] */ IDispatch *obj) = 0;
};
and then the class definition inherits from
public IDispatchImpl<ITest>
I've tried mixing activeqt and ATL, but I've been unsuccessful so far. Should I be using dumpcpp instead? [edit] dumpcpp is useful if you want to call an existing COM object from Qt, but doesn't help to extract the interface for use in activeQt.[/edit] Is that the way to override the interface without mixing ATL and activeqt? I'm wondering if the qt tools and ATL both trying to generate the idl is the source of my struggles...
Thanks!
