Detailed Description

template<typename ObjectType>
class drn::foundation::UniqueQtPtr< ObjectType >

A representation of a Qt object that is not handled by the usual Qt memory pattern. When the Qt object derives from a QObject, its deletion is handled on the event loop else it’s deleted immediately upon destruction.

Template Parameters

ObjectType

The type of the object stored.

Constructor & Destructor Documentation

UniqueQtPtr() [1/2]

template<typename ObjectType>

drn::foundation::UniqueQtPtr< ObjectType >::UniqueQtPtr ( ObjectType *const obj = nullptr )

explicit

Constructs an object to manage the given Qt object.

Precondition

The pointer to the Qt object to be managed cannot have a parent.

Parameters

obj	A pointer to the Qt object to be managed.

Here is the caller graph for this function:

UniqueQtPtr() [2/2]

template<typename ObjectType>

drn::foundation::UniqueQtPtr< ObjectType >::UniqueQtPtr

(

std::nullptr_t

)

Constructs an object with a nullptr, initialising it to manage no object. This is useful when you need to explicitly initialise a pointer to a null state, ensuring that it does not point to any Qt object initially.

Member Function Documentation

operator!=()

template<typename ObjectType>

bool drn::foundation::UniqueQtPtr< ObjectType >::operator!= ( std::nullptr_t ) const

noexcept

Inequality operator for checking null.

Returns

False when the pointer is null, true otherwise.

operator==()

template<typename ObjectType>

bool drn::foundation::UniqueQtPtr< ObjectType >::operator== ( std::nullptr_t ) const

noexcept

Equality operator for checking null.

Returns

True when the pointer is null, false otherwise.
