Each application has to write its own, and it is reasonable for the layout system itself [which, as I've pointed out, is part of the application - there is no such thing as a system service] to need access to this information.

This one is for "JAVAsucks" -
https://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html
This one is for wxWidgets - https://docs.wxwidgets.org/3.0/overview_sizer.html
This one is for Qt - https://doc.qt.io/qt-5/layout.html
This one is for GTK -
https://developer.gnome.org/gtk3/stable/LayoutContainers.html

Are you still going to argue "it does not exist"?

Every cross-platform has a layout system otherwise it will a burden to write
cross-platform apps.

Thank you

Thank you.
