  forma-ui

  • A retained widget tree with WidgetId handles, editable in place
    (remove, move_widget, set_style) or rebuilt from app state with
    Ui::rebuild, which matches widgets by key or position and keeps their
    state; key(..).memo(..) skips unchanged subtrees.
  • Layout with taffy (flexbox and grid) through a Style builder; lengths
    are written at 1x and scaled to the display.
  • Text with cosmic-text: font registration, families and fallback, bundled
    DejaVu fonts; text fields and areas with selection, undo and redo, input
    masks, placeholders, IME composition, and code-editor features (gutter,
    highlighting spans, decorations, find and replace, completion list, edit
    profiles). Editing a long text reshapes only the changed lines.
  • Input in forma's own vocabulary, with a rebindable Keymap, a
    Clipboard trait, keyboard focus on every control, popups and modal
    dialogs.
  • Events, Actions for turning them into app messages, and Component
    and CustomWidget for app-defined widgets.
  • Ready-made widgets: menus and context menus, menu bar, select, combo box,
    dialog, radio group, number field, range slider, collapsible section,
    toasts, progress and busy indicators, virtual list, tree view, table,
    docking, tab bar, color picker.
  • Themes (palette, metrics, text defaults) with dark and light built in.
  • Transitions, tweens and springs on a UI clock; the UI says when it needs
    a frame, so an idle app does no work.
  • Accessibility through AccessKit (the accesskit feature): roles, names,
    states, text with caret and selection, actions from assistive technology.
  • forma::testing::Harness and snapshot helpers for headless tests.

  forma-wgpu

  • SurfaceRenderer for a window, and Renderer for drawing into an app's
    own render pass on its device.
  • Rounded rectangles, borders, shadows, lines, a growing glyph atlas, SVG
    icons, images by handle, clipping.

  forma-winit

  • Input translation from winit, cursor icons, input method placement, the
    OS clipboard and AccessKit.
  • run: a whole app from the App trait, drawing only when needed.
