Uno Toolkit ZoomContentControl — 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 ZoomContentControl Documentation

uno_platform_docs_search("Uno Toolkit ZoomContentControl zoom pan pinch mouse wheel")

Primary documentation page:

• ZoomContentControl: external/uno.toolkit.ui/doc/controls/ZoomContentControl.md

Fetch the page:

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

Critical Rules

• The fit-to-available-size property is AutoFit (boolean). There is no AutoFitToCanvas property — that name does not exist on ZoomContentControl.
• Programmatic zoom uses methods ZoomTo(float) and ZoomToRect(Rect) on the control instance — not a settable Zoom property.

Key Principles (Stable)

• MinZoomLevel and MaxZoomLevel — zoom range
• ZoomLevel — current zoom (bindable, two-way)
• IsZoomAllowed — enable/disable zoom
• IsPanAllowed — enable/disable pan
• AutoFit — fit content to available size
• Supports mouse wheel, middle-click pan, pinch-to-zoom gestures
• XAML namespace: xmlns:utu="using:Uno.Toolkit.UI"
