QLinkedList iterator

Hi,

I have a QLinkedList as a variable member of a class.
I want an iterator(mutable) variable to use it in my class methods without having to create an iterator every time. What I want is like a pointer that points the actual item.

I'm reading about it but I'm not sure how to do it.

Thanks,

Depends on which item you want.
You have QLinkedList::begin that gives you a linked list iterator pointing to the first element.

You can access the data with the * operator.

Hi,

The operator * don't exists at QLinkedList. It exist at QList.

Thanks,

it exists in QLinkedList::iterator.

Quote:

---

T & iterator::operator* () const
Returns a modifiable reference to the current item.
You can change the value of an item by using operator*() on the left side of an assignment, for example:
if (*it == "Hello")
*it = "Bonjour";
See also operator->().

Hi,

Ok, I understand how it works now.

Thanks,

Hi,

I'm having problems yet.

code.h

Code:

---

QLinkedList<MyClass*> m_qLinkedList;
QMutableLinkedListIterator<MyClass*> m_qIterator;  //The compiler don't let me do this

---

Any idea how to do a iterator variable?

Thanks,

Hi,

I'm trying to change:

Code:

---

QMutableLinkedListIterator<MyClass*> m_qIterator;

---

for:

Code:

---

QLinkedList<MyClass*>::iterator m_qIterator;

---

In the constructor:

Code:

---

m_qIterator = m_qLinkedList.begin();

---

I don't really know if this iterator will be persistent and if I can use it to insert, remove, ...
Will try it.

Thanks,
