A pointer to a class that contains pointers

[karim24]

hi i have a class that contains pointers,the class iherits nothing
@class MyClass
{
public:
MyClass();
~MyClass();

private:
//i have pointers here
};
MyClass::~MyClass()
{
qDebug()<<"destroyed..";
}
@

now i have to use this class as a pointer in vector like this:
@QVector<MyClass*> classes;
//push some classes in here but
//when i remove an element
classes.remove(index);
//the destructor doesn't get called,and i think that is the true definition of memory leak@

so how do i make it call the destructor

remove only removes the pointer from the vector, but does not delete the object itself, so you need to delete the object when removing it.

@MyClass *class=classes.at(index);
classes.remove(index);
delete class;@

If you don't want to explicitly call delete, you could use a vector of shared pointers instead of using raw pointers in the vector.
Unless you use said shared pointer you should implement the assignment operator and copy-constructor.

Reason:
@MyClass instance1;
{
MyClass instance2 = instance1;
}
// at this point the private pointers in instance1 have been deleted.
