◆ connect() [1/4]

template<typename Func , typename... BoundArgs, typename std::enable_if_t< std::is_convertible< Func, std::function< void(const BoundArgs &...)> >::value > * = nullptr>
unsigned int tgui::SignalAnimation::connect ( const Func &  func,
const BoundArgs &...  args 
)
inline

Parameters
funcCallback function without unbound parameters
argsAdditional arguments to pass to the function
Returns
Unique id of the connection

unsigned int tgui::SignalAnimation::connect ( const Func &  func,
const BoundArgs &...  args 
)
inline

Connects a signal handler that will be called when this signal is emitted.

Parameters
funcCallback function that has an unbound ShowAnimationType as last parameter
argsAdditional arguments to pass to the function
Returns
Unique id of the connection

◆ connect() [3/4]

template<typename Func , typename... BoundArgs, typename std::enable_if_t< std::is_convertible< Func, std::function< void(const BoundArgs &..., bool)> >::value > * = nullptr>
unsigned int tgui::SignalAnimation::connect ( const Func &  func,
const BoundArgs &...  args 
)
inline

Connects a signal handler that will be called when this signal is emitted.

Parameters
funcCallback function that has an unbound bool (showing widget or not) as last parameter
argsAdditional arguments to pass to the function
Returns
Unique id of the connection

◆ connect() [4/4]

template<typename Func , typename... BoundArgs, typename std::enable_if_t< std::is_convertible< Func, std::function< void(const BoundArgs &..., ShowAnimationType, bool)> >::value > * = nullptr>
unsigned int tgui::SignalAnimation::connect ( const Func &  func,
const BoundArgs &...  args 
)
inline

Connects a signal handler that will be called when this signal is emitted.

Parameters
funcCallback function that has an ShowAnimationType and bool (showing widget or not) as two last parameters
argsAdditional arguments to pass to the function
Returns
Unique id of the connection

◆ emit()

bool tgui::SignalAnimation::emit ( const Widget widget,
ShowAnimationType  type,
bool  visible 
)

Call all connected signal handlers.

Parameters
widgetWidget that is triggering the signal
typeType of the animation
visibleTrue when the widget became visible, false if the widget is now hidden
Returns
True when a callback function was executed, false when there weren't any connected callback functions

◆ operator()()

template<typename Func , typename... BoundArgs>
unsigned int tgui::SignalAnimation::operator() ( const Func &  func,
const BoundArgs &...  args 
)
inline

Connects a signal handler that will be called when this signal is emitted.

Parameters
funcCallback function that can be passed to the connect function
argsAdditional arguments to pass to the function
Returns
Unique id of the connection
