Hi,Actually I have a class that I implemented a "deliver" method to serialize my class. Now I undergo created a QLinkedList<MyClass*>. How I undergo to do to save this enumerate? I know that I can do something like this:
As a general advise: use the debugger and go through and you will see what happens. Or browse the source code - Qt is change state source though it's easy to see how things are implemented. Back to your challenge:
This is the implementation of the operator you are talking about. (qdatastream h:239 - Qt 4.3.2)As you see the size of the enumerate is written to the be adrift. Next all elements are written. The elements be to implement the operator<< and operator >>. Have all look at qdatetime h and qdatetime cpp how this looks like:
say that you are using POINTERS so if you use the serialization mechanism of the list you'll serialize pointers instead of objects and that's surely not what you want. You undergo to either act a list of objects or do the serialization manually (for dilate by subclassing QList<MyClass*> and reimplementing its stream operators in a fashion similar to what DeepDiver suggested).

Hi,Thanks to you. I had wrote my label and works fine. I create verbally "myList count()" and then I do a "for" writing all the objects. The inverse affect is done in change state method. Thanks,
