如何在Powershell GUI中從其他運行空間添加標簽？

Question

在我的Powershell GUI中，我有兩種模式：連接和斷開連接。 每個都有一個步驟列表。 該列表是從xml中讀取的，然后作為每個步驟的標簽加載到flowlayout面板中。 因此，如果我有8個連接步驟，則將在flowlayout面板中創建8個標簽。

我希望在更改模式時動態更改標簽。 如果我處於連接模式並傳遞到斷開連接模式，則需要從功能運行區在flowlayout面板中加載相關步驟。

在我的腳本中，我有三個運行空間（一個用於GUI，一個用於功能，一個用於計時器）。

在Gui運行空間中，PanelLabelInner（flowlayoutpanel）被包裝到PanelLabelOuter中。 這是用於垂直居中。 我需要將標簽添加到PanelLabelInner中。

我需要完成BUiltXML函數。 首先，在模式更改時刪除所有標簽，然后更新ui以顯示新標簽：我該怎么做？

有了這段代碼，什么也沒添加，我想我必須使用諸如update，refresh之類的東西。

gui運行空間：

$CommonHashTable.PanelLabelOuter=New-Object System.Windows.Forms.Panel
$CommonHashTable.PanelLabelOuter.BackColor = [string]$PanelLabelOuterCfg.BackColor
$CommonHashTable.PanelLabelOuter.Name ="PanelLabelOuter"
$CommonHashTable.PanelLabelOuter.BorderStyle =[string]$PanelLabelOuterCfg.BorderStyle
$CommonHashTable.PanelLabelOuter.Dock = "Fill"
$CommonHashTable.PanelLabelOuter.AutoSize = $false
$CommonHashTable.MiddleLayout.Controls.Add($CommonHashTable.PanelLabelOuter,2,0)

$CommonHashTable.PanelLabelInner=New-Object System.Windows.Forms.FlowLayoutPanel
$CommonHashTable.PanelLabelInner.AutoSize = $false
$CommonHashTable.PanelLabelInner.Height = $CommonHashTable.c*20
$CommonHashTable.PanelLabelInner.Left = [Int32]$PanelLabelInnerCfg.Left
$CommonHashTable.PanelLabelInner.Width= $CommonHashTable.PanelLabelOuter.Width
$top=[int32](($CommonHashTable.PanelLabelOuter.Size.Height -  $CommonHashTable.PanelLabelInner.Size.Height) / 2)
$CommonHashTable.PanelLabelInner.Top=$top
$CommonHashTable.PanelLabelInner.Padding= 0
$CommonHashTable.PanelLabelInner.Anchor = 'None'
$CommonHashTable.PanelLabelInner.FlowDirection = "TopDown"
$CommonHashTable.PanelLabelInner.WrapContents = $false
$CommonHashTable.PanelLabelInner.BackColor = [string]$PanelLabelInnerCfg.BackColor
$CommonHashTable.PanelLabelInner.Name ="PanelLabelInner"
$CommonHashTable.PanelLabelOuter.Controls.Add($CommonHashTable.PanelLabelInner)

函數運行空間

function BuiltXML{
        Switch ($CommonHashTable.Phase) {
                    {$CommonHashTable.Phase -eq "Connect"}
                        {
                                $ConnectLabelText = "Connection"
                                $CommonHashTable.sourceXML = [xml](Get-Content $ProductPath\Xml\ConnectionLabels.xml)

                        }

                    {$CommonHashTable.Phase -eq "Disconnect"}
                        {
                                $ConnectLabelText = "Logout"
                                $CommonHashTable.sourceXML = [xml](Get-Content $ProductPath\Xml\DeconnectionLabels.xml)
                        }
        }
        $CommonHashTable.steps= $CommonHashTable.sourceXML.Dialer.Steps.Stp
        $CommonHashTable.c = $CommonHashTable.steps.count
        $CommonHashTable.PanelLabelInner.Invoke([Action[string]] {
            $i =1
                #$CommonHashTable.PanelLabelInner.Controls.Remove($CommonHashTable.Lbl)
                $CommonHashTable.Lbl.Controls.Clear()
                foreach ($e in $CommonHashTable.steps) 
                {
                    $CommonHashTable.Lbl = New-Object System.Windows.Forms.Label
                    $CommonHashTable.Lbl.Size=New-Object System.Drawing.Size($CommonHashTable.PanelLabelInner.Size.Width,20) 
                    $CommonHashTable.Lbl.AutoSize = $false
                    $CommonHashTable.Lbl.Name = "Label"+$i
                    $CommonHashTable.Lbl.TextAlign = "MiddleLeft"
                    $CommonHashTable.Lbl.Text = $e.Label
                    $CommonHashTable.PanelLabelInner.Controls.Add($CommonHashTable.Lbl)
                    $i++
                }
            },
        'normal')
}

我找到了一個解決方案...該功能還根據標簽的數量構建了流程圖面板。 因此，我有一個具有良好高度的布局面板。 我只需要在需要切換時清除外面板，添加這些標簽，然后進行更新。

function BuiltXML{
    Switch ($CommonHashTable.Phase) {
                {$CommonHashTable.Phase -eq "Connect"}
                    {
                            $CommonHashTable.ConnectLabel.Text = "Connexion"
                            $sourceXML = [xml](Get-Content $ProductPath\Xml\ConnectionLabels.xml)

                    }

                {$CommonHashTable.Phase -eq "Disconnect"}
                    {
                            $CommonHashTable.ConnectLabel.Text = "Deconnexion"
                            $sourceXML = [xml](Get-Content $ProductPath\Xml\DeconnectionLabels.xml)
                    }
    }

     $etapes = $sourceXML.Dialer.Etapes.Etape 
     $c = $etapes.count

     $CommonHashTable.PanelLabelOuter.Invoke(

     [Action] {
        $CommonHashTable.PanelLabelOuter.Controls.Clear()
            $CommonHashTable.PanelLabelInner=New-Object System.Windows.Forms.FlowLayoutPanel
            $CommonHashTable.PanelLabelInner.AutoSize = $false
            $CommonHashTable.PanelLabelInner.Height = $c*20
            $CommonHashTable.PanelLabelInner.Left = [Int32]$PanelLabelInnerCfg.Left
            $CommonHashTable.PanelLabelInner.Width= $CommonHashTable.PanelLabelOuter.Width
            $top=[int32](($CommonHashTable.PanelLabelOuter.Size.Height -  $CommonHashTable.PanelLabelInner.Size.Height) / 2)
            $CommonHashTable.PanelLabelInner.Top=$top
            $CommonHashTable.PanelLabelInner.Padding= 0
            $CommonHashTable.PanelLabelInner.Anchor = 'None'
            $CommonHashTable.PanelLabelInner.FlowDirection = "TopDown"
            $CommonHashTable.PanelLabelInner.WrapContents = $false
            $CommonHashTable.PanelLabelInner.BackColor = [string]$PanelLabelInnerCfg.BackColor
            $CommonHashTable.PanelLabelInner.Name ="PanelLabelInner"
            $CommonHashTable.PanelLabelOuter.Controls.Add($CommonHashTable.PanelLabelInner)

            $i =1
            foreach ($e in $etapes) 
            {
                $CommonHashTable.Lbl = New-Object System.Windows.Forms.Label
                $CommonHashTable.Lbl.Size=New-Object System.Drawing.Size($CommonHashTable.PanelLabelInner.Size.Width,20) 
                $CommonHashTable.Lbl.AutoSize = $false
                $CommonHashTable.Lbl.Name = "Label"+$i
                $CommonHashTable.Lbl.TextAlign = "MiddleLeft"
                #$CommonHashTable.Lbl.Font = New-Object System.Drawing.Font([string]$lblCfg.Font,[int32]$lblCfg.Size,[System.Drawing.FontStyle]::[string]$lblCfg.Style)
                #$CommonHashTable.Lbl.ForeColor = [string]$lblCfg.Color
                $CommonHashTable.Lbl.Text = $e.Label
                $CommonHashTable.PanelLabelInner.Controls.Add($CommonHashTable.Lbl)
                $i++
            }
                $CommonHashTable.PanelLabelInner.update()
        } 
    )

}
