Qt信号 - 时隙交互。

Question

焕我想为了使用私有对象的信号出现以下其父对象的信号，我做的：

1. I create a signal and a slot (named, let's say, ParentSignal, ParentSlot) 
2. connect(private_objcet, SIGNAL(someSignal()), this, SLOT(ParentSlot())); 
3. and define parent slot like this: 

void ParentSlot() 
{ 
    emit ParentSignal(); 
} 

有没有办法做到这一点的过程直接，也就是说，没有ParentSlot？

Answer 1

QObject::connect(private_object, SIGNAL(someSignal()), this, SIGNAL(ParentSignal()));
