如何將 C# 代表連接到 boost::signal

Question

我嘗試以這種方式連接

文本存儲

typedef boost::signals2::signal<VOID(TextStore*, RECT*)> signal_GetCompExt;
signal_GetCompExt       m_sigGetCompExt;

信號處理器

delegate VOID GetCompsitionExtDelegate(TextStore* textStore, RECT* rect);
VOID onGetCompsitionExt(TextStore* textStore, RECT* rect);

連接信號

using namespace System::Runtime::InteropServices;
    m_TextStore->m_sigGetCompExt.connect(reinterpret_cast<TextStore::signal_GetCompExt::slot_type*>(Marshal::GetFunctionPointerForDelegate(gcnew GetCompsitionExtDelegate(this, &AppWrapper::onGetCompsitionExt)).ToPointer()));

但它告訴我

C2064   term does not evaluate to a function taking 2 arguments

在構建之前設置 Boost Root

路徑： TextServiceFramework\libtf\PropertySheet.props

BoostVersion boost_1_74_0

Answer 1

typedef void (*GetCompExtCallback)(TextStore* ts, RECT* rect);
m_TextStore->m_sigGetCompExt.connect(reinterpret_cast<GetCompExtCallback>(Marshal::GetFunctionPointerForDelegate(gcnew GetCompsitionExtDelegate(this, &AppWrapper::onGetCompsitionExt)).ToPointer()));
