Inheritance diagram for wxWindowPtr< T >:A reference-counted smart pointer for holding wxWindow instances.
This specialization of wxSharedPtr<T> is useful for holding wxWindow-derived objects. Unlike wxSharedPtr<T> or std::shared_ptr<>, it doesn't use the delete operator to destroy the value when reference count drops to zero, but calls wxWindow::Destroy() to safely destroy the window.
The template parameter T must be wxWindow or a class derived from it.

| wxWindowPtr< T >::wxWindowPtr | ( | ) |
Default constructor.
|
explicit |
Constructor.
Creates shared pointer from the raw pointer ptr and takes ownership of it.
|
explicit |
Constructor.
Creates shared pointer from the raw pointer ptr and deleter d and takes ownership of it.
| ptr | The raw pointer. |
| d | Deleter - a functor that is called instead of delete to free the ptr raw pointer when its reference count drops to zero. |
| wxWindowPtr< T >::wxWindowPtr | ( | const wxWindowPtr< T > & | tocopy | ) |
Copy constructor.
| wxWindowPtr<T>& wxWindowPtr< T >::operator= | ( | T * | ptr | ) |
Assignment operator.
Releases any previously held pointer and creates a reference to ptr.
| wxWindowPtr<T>& wxWindowPtr< T >::operator= | ( | const wxWindowPtr< T > & | tocopy | ) |
Assignment operator.
Releases any previously held pointer and creates a reference to the same object as topcopy.
| void wxWindowPtr< T >::reset | ( | T * | ptr = NULL | ) |
Reset pointer to ptr.
If the reference count of the previously owned pointer was 1 it will be deleted.
