Detailed Description

A centering layout.

A Gtk::CenterLayout is a layout manager that manages up to three children. The start widget is allocated at the start of the layout (left in LRT layouts and right in RTL ones), and the end widget at the end.

The center widget is centered regarding the full width of the layout.

Since gtkmm 3.96:
