概述
首先从Qt源码摘选出关于connect的函数的原型,其原型如下:
template <typename Func1, typename Func2>
static inline QMetaObject::Connection connect(const typename QtPrivate::FunctionPointer<Func1>::Object *sender, Func1 signal,
const typename QtPrivate::FunctionPointer<Func2>::Object *receiver, Func2 slot,
Qt::ConnectionType type = Qt::AutoConnection)
{
typedef QtPrivate::FunctionPointer<Func1> SignalType;
typedef QtPrivate::FunctionPointer<Func2> SlotType;
