Detailed Description

template<typename T>
class hi::v1::default_selection_delegate< T >

A delegate that control the state of a selection_widget.

Template Parameters

T	the type used as the key for which option is selected.

Constructor & Destructor Documentation

template<typename T >

hi::v1::default_selection_delegate< T >::default_selection_delegate	(	forward_of< observer< value_type > > auto &&	value,
		forward_of< observer< options_type > > auto &&	options,
		forward_of< observer< value_type > > auto &&	off_value )

inlinenoexcept

Construct a default selection delegate.

Parameters

value	The observer value which represents the selected option.
options	An observer std::vector<std::pair<value_type,label>> of all possible options.
off_value	The value used when none of the available options are selected.

template<typename T >

hi::v1::default_selection_delegate< T >::default_selection_delegate	(	forward_of< observer< value_type > > auto &&	value,

inlinenoexcept

Construct a default selection delegate.

Parameters

value	The observer value which represents the selected option.
options	An observer std::vector<std::pair<value_type,label>> of all possible options.
