✨ PoshUI v1.4.1 — Canvas Polish & Release Showcase

PoshUI Canvas release showcase

A polish release for PoshUI.Canvas. It brings a redesigned date picker and calendar, a showcase app that
takes Canvas to full stretch, and a complete guide to motion.

Nothing breaks. No cmdlet or parameter changed, so existing scripts run as they are. Every app that uses
Add-UICanvasDatePicker gets the new look automatically.

🆕 First Release With PoshUI.Canvas

This is the first signed release package since v1.3.1. Version 1.4.0 was never packaged, so everything it
added ships here for the first time:

  • PoshUI.Canvas: free-form apps from ~85 cmdlets, where a single .ps1 is the whole app
  • An engine-native workflow runner with live progress, retry, timeouts, skip conditions and reboot-resume
  • Off-gate script cards that stream output without freezing the app
  • Declarative cascading fields, tabs, menus, splitters, Viewbox and master/detail grids
  • A raw XAML escape hatch with -Actions wiring, and per-monitor V2 DPI
  • Authoring diagnostics: -Properties keys that nothing reads are logged by name

The full list is under 1.4.0 in the changelog.

📅 A Date Picker That Belongs in a Dark App

The old picker had no style of its own, so Canvas fell back to the stock Windows one. That meant:

  • a hard-coded white border around the text;
  • the old gradient calendar icon;
  • faint text on a translucent fill;
  • a light calendar popup, even inside a dark app.

Colours set on the outer control never reached the calendar inside it.

Every part is now themed, and follows Set-UITheme in both light and dark mode:

  • Full-contrast day numbers
  • An accent-filled selected day and a ring on today
  • Dimmed days from the neighbouring months
  • Chevron paging, with month and year views to match
  • An accent border when the field has focus

🚀 Release Showcase

Examples\Showcase-Release.ps1 is one script that shows what Canvas can do. It's in the release zip together
with the logo files it uses. From the extracted folder:

Get-ChildItem -Recurse | Unblock-File
powershell -NoProfile -STA -File .\Examples\Showcase-Release.ps1
  • Splash: the PoshUI logo is revealed in two halves on opposite axes, with the colour channels converging
    and a CRT power-down exit. It moves on to the app by itself.
  • Overview: a hero panel explaining Canvas, clickable explore cards and live metrics.
  • Charts: bar, spline area, donut and sparkline charts, bound to live data. Push new data and watch every
    chart animate again.
  • Motion: sixteen demos of movement (see below).
  • Forms: two-way binding, validation feedback and the new calendar.

Navigation is a custom icon rail on the left, plus Ctrl+1 to Ctrl+4, under a slim top bar of the app's own.

🎬 Motion, Three Ways

Motion in the showcase comes from three places, and all of them are available to any script:

Source What it looks like
Engine properties Stagger, HoverScale, Glow / GlowPulse: one line in -Properties
Runtime cmdlets Set-UICanvasAnimate with Linear, Cubic, Back, Bounce and Elastic easings; Spin; progress tweens; the -Clock elapsed timer
XAML islands Raw WPF inside Add-UICanvasXaml: a 3D cube, motion along a curve, colour animation, spring-on-hover, a particle field, an odometer, stroke draw-on

New guide: Animation & Motion. It covers:

  • what the engine animates for you, and where that stops;
  • why storyboards in a XAML island must start themselves;
  • the property paths that work, with a technique catalogue;
  • easing and timing guidance;
  • how to check that an animation works without watching it.

The AI context packs now include these motion rules too.

🔧 Fixed

  • Faint, dated date picker. See above.
  • A false [unused property] warning for Clock on elapsed-clock labels.
  • Garbled AI context packs. Docs saved without a byte-order mark came out with — wherever there was an
    em dash. The packs now also include every agent doc.

📦 Versions

Component Version
PoshUI engine (PoshUI.exe) 1.4.1
PoshUI.Canvas 1.4.1 (was 1.3.0; now matches the engine, and still accepts engine 1.4.0 or later)
PoshUI.Wizard / Dashboard / Workflow 1.3.1 (unchanged)

PoshUI.exe is Authenticode-signed. Check it with Get-AuthenticodeSignature .\bin\PoshUI.exe.

⚠️ Known Issue

Timers (-Refresh), state watchers and shortcuts registered on a page stay alive until the app closes. They are
registered again each time the user visits that page. If an app lets users move between pages a lot, throttle its
tickers. The showcase shows the pattern.

Requirement Version
Operating System Windows 10/11 (64-bit)
