Detailed Description

Child item of the grid.

Definition at line 323 of file grid.hpp.

Constructor & Destructor Documentation

◆ child() [1/2]

gui2::grid::child::child ( )
inline

Definition at line 330 of file grid.hpp.

◆ child() [2/2]

gui2::grid::child::child ( child &&  )
defaultnoexcept

Move constructor.

This is necessary in order that the child objects be moved instead of copied when the grid's child vector is resized. std::vector will utilize a move constructor as long as a non-throwing one is provided.
