Detailed Description
The LObject class is used to establish a hierarchy between Layers objects.
Member Function Documentation
LObject(LObject* parent = nullptr)
Constructs a Layers object and sets its parent.
void add_child(LObject* child)
Adds child to this object's list of child objects.
std::vector<LObject*>& children()
Returns a vector containing pointers to the child objects associated with this object.
void disconnect_destroyed(const LConnectionID& connection)
Disconnects the callback associated with connection to stop it from processing when this object gets destroyed.
std::vector<T*> find_children(bool recursive = false)
Returns a vector containing pointers to the child objects, of type T, associated with this object.
If recursive is true, then the returned vector will include children of children.
LString object_name() const
Returns the name of the object.
LConnectionID on_destroyed(std::function<void()> callback)
Stores callback and processes it whenever this object gets destroyed.
Returns a LConnectionID which can be used to disconnect the callback later through disconnect_destroyed().
LObject* parent() const
Returns a pointer to the object's parent.
Returns nullptr if no parent has been set.
void remove_child(LObject* child)
Removes child from this object's list of child objects.
void set_object_name(const LString& object_name)
Sets the object's name to object_name.
void set_parent(LObject* parent)
Sets the object's parent.
