Stack

Stack measures and overlays children in declaration order. Later children paint above earlier children.

Overlay local content

Stack {
  Image(app::images::cover)
      .Fit(ImageFit::Cover)
      .With(Frame{.height = 220.0F}),
  Text("Featured", TextRole::Title)
      .With(
          Align(HorizontalAlignment::Start, VerticalAlignment::End),
          Padding(16.0F),
          Foreground(Color::White())
      ),
}

Use child Align modifiers to position content within the stack’s available size. Apply ClipChildren with CornerRadius when overlays must remain inside a shaped surface.

Keep window layers separate

Stack controls painting order but does not create a window-level overlay. Use presentation services and layers for dialogs, menus, popups, tooltips, and other content that must escape the application subtree.

API

• Construction: Stack { children... } or an explicit child vector.
• Common modifiers: Frame, Padding, ClipChildren, CornerRadius.
• Child modifier: Align.

Read Presentation when content must live in a window layer instead of the local layout subtree.
