如何将 C# 委托连接到 boost::signal

Question

我试过这样连接

TextStore

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

信号处理器

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

连接信号

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()));

但它告诉我

C2064   term does not evaluate to a function taking 2 arguments

在构建之前设置 Boost Root

路径：TextServiceFramework\libtf\PropertySheet.props

升压版本 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()));
