获取对象指针指向

Question

I have a QList which I have inserted pointers of objects into. I am trying to iterate through this QList to read the name of these objects. Whenever I do so, I am getting the address of these objects as oppose to reading the object name itself. I am wondering how would I be able to read the object name instead of the address?

QList<MyObject*> newObjectList;
QList<MyObject*>::iterator i;

MyObject *pNewObject = new MyObject(name);
MyObject.append(pNewObject); 

for (i = newObjectList.begin(); i != newObjectList.end(); i++) {
    cout << "\n" << *i << "\n";
}

Answer 1

When you're dereferencing i, you need to call the function to get the name from your object. Something like this:

for (i = newObjectList.begin(); i != newObjectList.end(); i++) {
    // i right now is the iterator, and points to a pointer. So this will need to be
    // dereferenced twice.
    cout << "\n" << (*i)->getName() << "\n";
}

当您取消引用迭代器i（即*i ）时，您引用了一个MyObject*类型的对象，它是一个指针，您必须再次取消引用它以获取对象的引用：

*(*i)
