使用 Powershell Windows 窗体将复选框添加到列表框 [英] Add checkboxes to Listbox with Powershell Windows Forms

问题描述

我正在根据我之前的帖子创建一个新问题:
在 Powershell (Winforms) 中更改单个列表框项目的颜色

I am creating a new question based on my previous post :
Change the Color of Individual ListBox items in Powershell (Winforms)

我的以下代码运行良好(感谢 Micky Balladelli)，但我的老板让我添加复选框.如何修改此代码以添加一些复选框?

I have got the following code working very well (thanks to Micky Balladelli) but my boss asked me to add checkboxes. How can I adapt this code to add some checkboxes?

我在 MSDN 上的 ListBox 属性中进行了搜索，但没有看到任何添加复选框的属性.也许使用 CheckedListBox 类会更好，但在这种情况下，显示我的颜色看起来很复杂.

I searched on MSDN in the ListBox Properties and I didn't saw any properties to add checkboxes. Maybe it would be better to use the CheckedListBox class but in that case it looks complicated to display my colours.

我尝试过 Listview 类，但这不是我所期望的.

I tried with Listview class but it's not what I am expecting for.

任何帮助将不胜感激！

function add {
 $status='logged1','disconnected1','locked1','logged2','disconnected2','locked2','logged3','disconnected3','locked3'
 foreach ($s in $status)
 {
    $listbox.Items.Add($s)

  [System.Object] $sender, 
  [System.Windows.Forms.DrawItemEventArgs] $e

   #Suppose Sender de type Listbox
 if ($Sender.Items.Count -eq 0) {return}

   #Suppose item de type String
 $lbItem=$Sender.Items[$e.Index]
 if ( $lbItem.contains('locked'))

    $Color=[System.Drawing.Color]::yellowgreen

推荐答案

诀窍是使用 ListView 而不是 CheckedListBox.

The trick is to use ListView instead of CheckedListBox.

以下包含有相当多变化的完整代码.

The following contains the full code with quite a bit of changes.

function add {
 $status='logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','logged1','disconnected1','locked1','logged2','disconnected2','locked2','logged3','disconnected3','locked3'
