#### Description [src]

    final class Adw.WrapBox : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget, Gtk.Orientable {
      /* No available fields */
    }

A box-like widget that can wrap into multiple lines.

`AdwWrapBox` is similar to `GtkBox`, but can wrap lines when the widgets cannot fit otherwise. Unlike `GtkFlowBox`, the children aren’t arranged into a grid and behave more like words in a wrapping label.

Like `GtkBox`, `AdwWrapBox` is orientable and has spacing:

- `AdwWrapBox:child-spacing` between children in the same line;
- `AdwWrapBox:line-spacing` between lines.

Note

Unlike `GtkBox`, `AdwWrapBox` cannot follow the CSS `border-spacing` property.

Use the `AdwWrapBox:natural-line-length` property to determine the layout’s natural size, e.g. when using it in a `GtkPopover`.

Normally, a horizontal `AdwWrapBox` wraps left to right and top to bottom for left-to-right languages. Both of these directions can be reversed, using the `AdwWrapBox:pack-direction` and `AdwWrapBox:wrap-reverse` properties. Additionally, the alignment of each line can be controlled with the `AdwWrapBox:align` property.

Lines can be justified using the `AdwWrapBox:justify` property, filling the entire line by either increasing child size or spacing depending on the value. Set `AdwWrapBox:justify-last-line` to justify the last line as well.

By default, `AdwWrapBox` wraps as soon as the previous line cannot fit any more children without shrinking them past their natural size. Set `AdwWrapBox:wrap-policy` to `ADW_WRAP_MINIMUM` to only wrap once all the children in the previous line have been shrunk to their minimum size.

To make each line take the same amount of space, set `AdwWrapBox:line-homogeneous` to `TRUE`.

Spacing and natural line length can scale with the text scale factor, use the `AdwWrapBox:child-spacing-unit`, `AdwWrapBox:line-spacing-unit` and/or `AdwWrapBox:natural-line-length-unit` properties to enable that behavior.

See `AdwWrapLayout`.

## CSS nodes

`AdwWrapBox` uses a single CSS node with name `wrap-box`.

## Accessibility

`AdwWrapBox` uses the `GTK_ACCESSIBLE_ROLE_GROUP` role.
