Constructor & Destructor Documentation

Callback() [1/5]

G3D::GuiControl::Callback::Callback ( )

inline

Callback() [2/5]

G3D::GuiControl::Callback::Callback ( std::function< void(void)>  function )

inline

Create a callback from a function, e.g., GuiControl::Callback(&printWarning)

Callback() [3/5]

template<class Class >

G3D::GuiControl::Callback::Callback ( Class *const  object, void(Class::*)()  method  )

inline

Create a callback from a class and method of no arguments, e.g., App* app = ...; Callback( app, &App::endProgram ); .

If the method is defined on a base class and not overriden in the derived class, you must cast the pointer: Callback(static_cast<Base*>(ptr), &Base::method);

Callback() [4/5]

template<class Class >

G3D::GuiControl::Callback::Callback ( const shared_ptr< Class > &  object, void(Class::*)()  method  )

inline

Create a callback from a reference counted class and method of no arguments, e.g.,.

shared_ptr<Player> player = ...; 
pane->addButton("Jump", GuiControl::Callback(player, &Player::jump));

Callback() [5/5]

G3D::GuiControl::Callback::Callback ( const Callback &  c )

inline

Copy constructor.
