用户界面-如何在Powershell GUI中添加来自不同运行空间的标签

Question

在我的Powershell GUI中，我有两种模式：连接和解除连接。每个步骤都有一个步骤列表。该列表从xml中读取，然后加载到流程布局面板中，作为每个步骤的标签。因此，如果我有8个连接步骤，我将在流程布局面板中创建8个标签。

我希望在模式更改时动态更改标签。如果我处于连接模式并转到断开连接模式，我需要从函数运行空间加载流程布局面板中的相关步骤

在我的脚本中，我有三个运行空间（一个用于GUI，一个用于函数，另一个用于计时器）。

在Gui运行空间中，PanelLabelInner（流程布局面板）被包装成PanelLabel Outer。这是用于垂直居中。我需要将标签添加到PanelLabelInner中。

我需要完成BUiltXML函数。首先，在模式更改时删除所有标签，然后更新ui以显示新标签：我该怎么做？

对于这段代码，没有添加任何内容，我想我必须使用更新、刷新。。。

桂运行空间：

$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)

function BuiltXML{
        Switch ($CommonHashTable.Phase) {
                    {$CommonHashTable.Phase -eq "Connect"}
                        {
                                $ConnectLabelText = "Connection"

                    $CommonHashTable.Lbl.TextAlign = "MiddleLeft"
                    $CommonHashTable.Lbl.Text = $e.Label

            },

我找到了一个解决方案。。。该函数还构建了与标签数量相关的流程布局面板。所以我有一个高度很好的流程布局面板。我只需要在需要切换时清除外部面板，添加这些标签，然后进行更新。

function BuiltXML{
    Switch ($CommonHashTable.Phase) {
                {$CommonHashTable.Phase -eq "Connect"}
                    {
                            $CommonHashTable.ConnectLabel.Text = "Connexion"
                            $sourceXML = [xml](Get-Content $ProductPathXmlConnectionLabels.xml)
                    }
                {$CommonHashTable.Phase -eq "Disconnect"}
                    {
                            $CommonHashTable.ConnectLabel.Text = "Deconnexion"
                            $sourceXML = [xml](Get-Content $ProductPathXmlDeconnectionLabels.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()
        } 
    )

}
