Detailed Description

template<typename Layout_t, typename Projection = Identity, typename Comparison = std::less< std::invoke_result_t<Projection, std::add_const_t<std::add_lvalue_reference_t< typename Layout_t::Child_t>>>>>
class ox::layout::Set< Layout_t, Projection, Comparison >

Provides a set-like interface to Layout_t.

Projection transforms a Layout::Child_t into a comparable. Comparison is fed the output of Projection, used to find insertion pos. Comparison{}(Projection{}(element), Projection{}(child));

Member Function Documentation

find_child()

template<typename Layout_t , typename Projection = Identity, typename Comparison = std::less< std::invoke_result_t<Projection, std::add_const_t<std::add_lvalue_reference_t< typename Layout_t::Child_t>>>>>

auto ox::layout::Set< Layout_t, Projection, Comparison >::find_child ( Key_t const &  key ) -> Child_t*

inline

Find a child widget by its key type(the result of the Projection fn).

Uses the Projection function on each child until a result equal to key is found. Retuns nullptr if no child found.

make_child()

template<typename Layout_t , typename Projection = Identity, typename Comparison = std::less< std::invoke_result_t<Projection, std::add_const_t<std::add_lvalue_reference_t< typename Layout_t::Child_t>>>>>

template<typename Widget_t = Child_t, typename... Args>

auto ox::layout::Set< Layout_t, Projection, Comparison >::make_child ( Args &&...  args ) -> Widget_t&

inline

Create a Widget and insert it into the list of children.

Return a reference to this newly created Widget.
