Optional unbound parameters:

• AnimationType

Member Function Documentation

connect() [1/2]

template<typename Func , typename... BoundArgs, typename std::enable_if_t< std::is_convertible< Func, std::function< void(const BoundArgs &...)> >::value > * = nullptr>

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

inline

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

Parameters

func	Callback function without unbound parameters
args	Additional arguments to pass to the function

Returns

Unique id of the connection

connect() [2/2]

template<typename Func , typename... BoundArgs, typename std::enable_if_t< std::is_convertible< Func, std::function< void(const BoundArgs &..., AnimationType)> >::value > * = nullptr>

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

inline

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

Parameters

func	Callback function that has an unbound AnimationType as last parameter
args	Additional arguments to pass to the function

Returns

Unique id of the connection

emit()

bool tgui::SignalAnimationType::emit	(	const Widget *	widget,
		AnimationType	type )

Call all connected signal handlers.

Parameters

widget	Widget that is triggering the signal
type	Type of the animation

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::SignalAnimationType::operator() ( const Func & func, const BoundArgs &... args )

inline

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

Parameters

func	Callback function that can be passed to the connect function
args	Additional arguments to pass to the function

Returns

Unique id of the connection
