Member Typedef Documentation

typedef boost::signals2::signal< void( Core::View2D, Core::ActionSource ) > Core::StateView2D::value_changed_signal_type

Signal when the data in the state is changed, the second parameter indicates the source of the change

Member Function Documentation

bool Core::StateView2D::set	(	const Core::View2D &	value,
		Core::ActionSource	source = `Core::ActionSource::NONE_E`
	)

Set the value of the state variable NOTE: this function by passes the action mechanism and should only be used to enforce a constraint from another action.

bool Core::StateView2D::validate_variant	(	Variant &	variant,
		std::string &	error
	)

protectedvirtual

Validate a variant parameter This function returns false if the parameter is invalid or cannot be converted and in that case error will describe the error.

Implements Core::StateBase.
