views: Add protected virtual destructor to TabbedPaneListener.
The use of a protected virtual destructor is to prevent the destruction of a
derived object via a base-class pointer.
That's it, TabbedPaneListenere should only be deleted through derived class.
Example:
class FooListener {
public:
...
protected:
virtual ~FooListener() {}
};
class Foo : public FooListener {
};
FooListener* listener = new Foo;
delete listener; // It should prevent this situation!
