[Qt-interest] Question regarding pointer parameters in functions

[Patric]

Is there a way to see which QT functions, that take pointers as parameters, are deleting the memory after that. Because otherwise this code for example, 

 QStandardItemModel model;
 QStandardItem *parentItem = model.invisibleRootItem();
 for (int i = 0; i < 4; ++i) {
     QStandardItem *item = new QStandardItem(QString("item %0").arg(i));
     parentItem->appendRow(item);
     parentItem = item;
 }from my point of view would create memory leak. And we should know when we need to release memory and when not. If the class was imlicitly shared, there would not be a problem. But QStandardItem is not such a class.Regards,Patric----- Original Message -----

  I think the QStandardItemModel object takes ownership of the memory allocated in this case.

    Only objects created on the stack in that function will be removed when function ends.

      Hello, 
      does anyone know what happens if we pass a pointer as parameter to function in QT ? 
      Will the function release the memory of the object in the pointer, when it finish working with it ? 

      For example 

      void QStandardItemModel::appendRow ( QStandardItem * item ), if I call it the following way : appendRow(new QStandardItem("testItem"));

      Thank you in advance,
      Patric
