ComboBox 处于关闭状态的鼠标事件处理程序

Question

这是我正在寻找的代码，当鼠标从列表中的一项移动到下一项时，当下拉列表处于按下状态时，我正在寻找正确的方法来捕获任何鼠标移动。

Add-Type -AssemblyName System.Windows.Forms

$Form                        = New-Object System.Windows.Forms.Form
$Form.StartPosition          = 'CenterScreen'

$cbSearch                    = New-Object System.Windows.Forms.ComboBox
$cbSearch.Width              = 280
$cbSearch.Items.AddRange(@('Mixed content', 'More stuff', 'ANOTHER THING CONTENT', 'Item ?', 'Mixed item'))
$Form.Controls.Add($cbSearch)

# Event handler required for when the dropdown is in it's downed state. Like
# MouseCaptureChanged only when the dropdown is down and the mouse is moved over
# each item.
$cbSearch.Add_MouseCaptureChanged({ selectChanged $this $_ })

# Event handler action for the cbSearch control.
function selectChanged ($sender, $event) {
  write-host ($cbSearch.Text)
}

[void]$Form.ShowDialog()

这可能吗？我已经尝试了所有我能看到的可用鼠标事件处理程序。

$cbSearch.Add_MouseCaptureChanged({ selectChanged $this $_ })
$cbSearch.Add_MouseEnter({ selectChanged $this $_ })
$cbSearch.Add_MouseHover({ selectChanged $this $_ })
$cbSearch.Add_MouseLeave({ selectChanged $this $_ })

这是我希望在将鼠标悬停在每个项目上时发生偶数的时间。
