aui::HVLayout#
Shared implementation of AVerticalLayout and AHorizontalLayout.
| Header: | #include <AUI/Layout/HVLayout.h> |
| CMake: | aui_link(my_target PUBLIC aui::views) |
Detailed Description#
HVLayout does not strictly requires to layout AView. The only requirement is to pass range of items that implement methods required by HVLayout (as AView does). This make compile time polymorphism possible.
ASplitter is an example of object that requires AHorizontalLayout/AVerticalLayout-like behaviour with some changes.
