CenterBox
Object Hierarchy:
Description:
public sealed class CenterBox : Widget, Accessible, Buildable, ConstraintTarget, Orientable
`GtkCenterBox` arranges three children in a row, keeping the middle child centered as well as possible.
To add children to `GtkCenterBox`, use [method@Gtk.CenterBox.set_start_widget], [method@Gtk.CenterBox.set_center_widget] and [ method@Gtk.CenterBox.set_end_widget].
The sizing and positioning of children can be influenced with the align and expand properties of the children.
GtkCenterBox as GtkBuildable
The `GtkCenterBox` implementation of the `GtkBuildable` interface supports placing children in the 3 positions by specifying “start”, “center” or “end” as the “type” attribute of a `<child>` element.
CSS nodes
`GtkCenterBox` uses a single CSS node with the name “box”,
The first child of the `GtkCenterBox` will be allocated depending on the text direction, i.e. in left-to-right layouts it will be allocated on the left and in right-to-left layouts on the right.
In vertical orientation, the nodes of the children are arranged from top to bottom.
Accessibility
Until GTK 4.10, `GtkCenterBox` used the `GTK_ACCESSIBLE_ROLE_GROUP` role.
Starting from GTK 4.12, `GtkCenterBox` uses the `GTK_ACCESSIBLE_ROLE_GENERIC` role.
