由于 Winforms 中的 AutoSize 不起作用，如何创建动态布局？

Question

尝试在 PowerShell 中创建简单的 win 窗体。会有一些自动计算的复选框，我正在为大小而苦苦挣扎 - 似乎 'AutoSize' 是胡说八道，返回的值不知从何而来。任何人都可以帮助并建议您如何创建动态定位吗？基于哪些值？

    $chkVMBox.Controls.Add($chkVMNICs)
    #$lastControl = $chkVMNICs

    #$vLocation = $lastControl.Bottom+$shift
    $vLocation = $chkVMNICs.Bottom+$shift
    $chkbVMdiag = New-Object System.Windows.Forms.Checkbox 
    $chkbVMdiag.Location = New-Object System.Drawing.Point(10,$vLocation) 
    #$chkbVMdiag.Anchor = 'left,top'
    $chkbVMdiag.AutoSize = $true
    $chkbVMdiag.Text = "Boot Diagnostics"
    $chkbVMdiag.TabIndex = $allChkb++
    $chkVMBox.Controls.Add($chkbVMdiag)
    
    
    $vLocation = $chkVMBox.bottom + 40
    $btOK = New-Object System.Windows.Forms.Button
    $btOK.Location = New-Object System.Drawing.Size(15,$vLocation)
    $btOK.Size = New-Object System.Drawing.Size(70,20)
    $btOK.Text = "OK"
    $btOK.DialogResult = [System.Windows.Forms.DialogResult]::OK
    #$btOK.Anchor = 'left,bottom'

    $btCancel = New-Object System.Windows.Forms.Button
    $btCancel.Location = New-Object System.Drawing.Size(95,$vLocation)
    $btCancel.Size = New-Object System.Drawing.Size(70,20)
    $btCancel.Text = "Cancel"
    $btCancel.DialogResult = [System.Windows.Forms.DialogResult]::Cancel
    #$btCancel.Anchor = 'right,bottom'     

$chkForm.AcceptButton = $btOK
$chkForm.CancelButton = $btCancel
$chkForm.Controls.AddRange(@($chkVMBox, $btOK, $btCancel))

[void]$chkForm.ShowDialog()

效果： effect of code

主窗体右侧有一些大填充
在复选框列表中 - 第一个有额外的 space，第二个控件 space 加倍
最后一个复选框下面有一些填充
chkVMBox (main box) returns 'size = 100' 'bottom = 110' 并且使用该值的按钮实际上在其他控件下并且不可见。

似乎 ALL VALUES 返回 'autosize' 是胡说八道。那么如何在不知道 sizes/number 预先元素的情况下创建动态布局？

Answer 1

主窗体右边有一些大填充
在复选框列表中 - 第一个有额外的 space，第二个控件 space 加倍
最后一个复选框下面有一些填充

设置 .AutoSizeMode = 'GrowAndShrink' as well as .MinimumSize 属性以及 .AutoSize。

按钮……其实在其他控件下不可见

按钮位置源自$chkVMBox.bottom；使用 $chkForm.Controls.Add($chkVMBox) before 计算按钮的垂直位置并从 ~~$chkForm.Controls.AddRange(…)~~

中删除 $chkVMBox

创建动态布局，预先不知道 sizes/number 元素:

我会尝试计算控件相对于不变量的水平和垂直位置以及（最小）大小；例如，这些是根据以下代码中的 $chkForm.Font 计算得出的（愿望显然 不一致 :)，请参阅 $hShift 和 $vShift 变量，它们的值和用法。
