Uno Toolkit Autolayout

Uno Toolkit AutoLayout — Agent Skill

Workflow

Docs lookup: call uno_platform_docs_search(...) first, then uno_platform_docs_fetch(sourcePath="…") using the sourcePath field from a result (a relative .md path; add the result's anchor for a section). Never pass a URL, a .html link, or a hand-built path.

Step 1: Fetch the AutoLayout Documentation

uno_platform_docs_search("Uno Toolkit AutoLayout panel Figma spacing alignment")

Primary documentation page:

• AutoLayout Control: external/uno.toolkit.ui/doc/controls/AutoLayoutControl.md

Fetch the page:

uno_platform_docs_fetch(sourcePath="external/uno.toolkit.ui/doc/controls/AutoLayoutControl.md")

Step 2: For How-To Walkthroughs

uno_platform_docs_search("AutoLayout howto walkthrough example Figma")

Key Principles (Stable)

Container properties (set on the <utu:AutoLayout> element itself):

• Orientation — Horizontal or Vertical (primary axis)
• Spacing — gap between children (like Figma auto-layout spacing)
• Justify — SpaceBetween distribution
• PrimaryAxisAlignment — alignment on the primary axis (Start, Center, End, Stretch)
• CounterAxisAlignment — alignment on the cross axis (Start, Center, End, Stretch)
• Padding — Figma-anchor-style padding (Thickness)

Per-child attached properties (set on children of an AutoLayout, note: NOT the same names as the container properties):

• utu:AutoLayout.PrimaryAlignment — override on primary axis (Auto or Stretch)
• utu:AutoLayout.CounterAlignment — override on counter axis (Start, Center, End, Stretch) — CounterAlignment, NOT CounterAxisAlignment
• utu:AutoLayout.PrimaryLength — fixed size along orientation axis (double)
• utu:AutoLayout.CounterLength — fixed size perpendicular to orientation (double)
• utu:AutoLayout.IsIndependentLayout — absolute positioning (bool)

There is no AutoLayout.Counterpart, no AutoLayout.SetCounterAxisAlignment(...), no AutoLayout.Align, no AutoLayout.MainAxis, no AutoLayout.CrossAxis. If unsure, the canonical surface is the table above — do not invent member names.
