Updated, Hippy Dippy PowerShell Clock with ShowUI

I posted PowerShell Clock with ShowUI. Ravi, another PowerShell MVP, tried the sample using the AsJob parameter. The AsJob will run the PowerShell WPF GUI in the background. Unfortunately, the FontSize and other parameters would not set correctly and the clocked was not readable.

After emailing James Brundage, a fellow ShowUI author , he blogged Six Steps for Writing ShowUI Controls and a video tutorial based on this clock example.

Definitely check it out, he kicks it up a notch with data context’s, PowerShell DataSources. splatting, adding event handlers and more.

Here is my updated clock code

Run it with either –Show or –AsJob

HippyDippy-Clock -Show
HippyDippy-Clock -AsJob

function HippyDippy-Clock {
    param (
        [string]$Name,
        [Int]$Row,
        [Int]$Column,
        [Int]$RowSpan,
        [Int]$ColumnSpan,
        [Int]$Width,
        [Int]$Height,
        [Double]$Top,
        [Double]$Left,
        [Windows.Controls.Dock]$Dock,
        [Switch]$Show,
        [Switch]$AsJob
    )            

    begin {ipmo showui}
    process {
        if (-not $psBoundParameters.Background) {
            $psBoundParameters.Background = 'Transparent'
        }                        

        $uiParameters = @{} + $psBoundParameters            

        Border @uiParameters -On_Loaded {
            $this.Child = Grid -Columns 150, 300* {
