QObjectParentUniquePtr () | |
Creates a new empty QObjectParentUniquePtr. | |
QObjectParentUniquePtr (T *child, QObject *parent) | |
Takes a new QObjectParentUniquePtr and assign a child to it. | |
~QObjectParentUniquePtr () | |
Will delete the contained object if the parent still exists. | |
void | clear () |
Clears the pointer. | |
T * | data () const |
Returns the raw pointer to the managed QObject. | |
T * | get () const |
Returns the raw pointer to the managed child. | |
bool | isNull () const |
Checks if the managed pointer is nullptr . | |
operator bool () const | |
Checks if the pointer managed by this object is nullptr . | |
operator T* () const | |
Const getter for the managed raw pointer. | |
T & | operator* () const |
Dereferences the managed child. | |
T * | operator-> () const |
Returns a raw pointer to the managed child. | |
QObjectParentUniquePtr< T > & | operator= (T *child) |
Assigns a new child to the pointer. | |
T * | release () |
Clears the pointer and returns it. | |
void | reset (T *p=nullptr) |
Will reset the managed pointer to p. | |
void | setParentOwner (QObject *parent) |
Sets the parent object. | |
Keeps a pointer to an object owned by a QObject parent, and deletes it whenever this parent object is deleted.
It keeps a weak pointer to the QObject parent internally and the object pointer be set to nullptr
whenever the parent QObject is deleted.
