class Gtk::CenterLayout

Overview

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 left-to-right locales and right in right-to-left ones), and the end widget at the end.

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

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/center_layout.cr
