问题描述
我正在尝试实现PowerShell表单,以便在后台桌面上覆盖淡淡的叠加层。
我认为实现此目的的唯一方法是使用两种形式-一种显示全屏覆盖(背景形式),另一种是实际(主要)形式。但是,当我单击(或取消激活)主窗体时,我希望一切都关闭。但是它不再关闭,我不知道为什么吗?我感觉当我单击主窗体时,单击事件正在尝试单击背景窗体(由于主窗体具有焦点而不能),并且“停用”事件不再起作用?
任何帮助表示赞赏:
[void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
[void][System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[System.Windows.Forms.Application]::EnableVisualStyles()
$windowsGreyTrans = [System.Drawing.Color]::FromArgb(20,43,43)
$windowsGreyOff = [System.Drawing.Color]::FromArgb(43,43)
$windowsGreyOn = [System.Drawing.Color]::FromArgb(60,60,60)
$bgform = New-Object System.Windows.Forms.Form
$bgform.WindowState = 'Maximized'
$bgform.ShowInTaskbar = $false
$bgform.MaximizeBox = $false
$bgform.Opacity = 0.5
$bgform.ControlBox = $false
$bgform.FormBorderStyle = [System.Windows.Forms.FormBorderStyle]::none
[void]$bgform.show()
$form = New-Object System.Windows.Forms.Form
$form.Size = New-Object System.Drawing.Size(200,40)
$Form.StartPosition = "CenterScreen"
$form.ShowInTaskbar = $false
$form.Name ="Power"
$form.MaximizeBox = $false
$form.ControlBox = $false
$form.FormBorderStyle = [System.Windows.Forms.FormBorderStyle]::none
$shutdownBtn = New-Object System.Windows.Forms.Button
$shutdownBtn.Location = New-Object System.Drawing.Point(0,0)

$shutdownBtn.FlatStyle = "Flat"
$shutdownBtn.UseVisualStyleBackColor = $True
$shutdownBtn.BackColor = $windowsGreyOff
$shutdownBtn.FlatAppearance.BorderSize = 0
$shutdownBtn.ForeColor = "White"
$shutdownBtn.Font = "Segoe UI,10pt"
#$shutdownBtn.Cursor = [System.Windows.Forms.Cursors]::Hand
$shutdownBtn.Add_Click({
try {
}
catch{
}
})
$shutdownBtn.Add_MouseEnter({
$this.BackColor = $windowsGreyOn
})
$shutdownBtn.Add_MouseLeave({
$this.BackColor = $windowsGreyOff
})
$form.Controls.Add($shutdownBtn)
$form.Add_Deactivate({

$form.Add_Shown({

解决方法
我为您提出了一个更好的解决方案,使用tablelayoutpanel将按钮居中并拦截点击事件。
尝试一下:
[void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
[void][System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[System.Windows.Forms.Application]::EnableVisualStyles()
$windowsGreyTrans = [System.Drawing.Color]::FromArgb(20,43,43)
$windowsGreyOff = [System.Drawing.Color]::FromArgb(43,43)
$windowsGreyOn = [System.Drawing.Color]::FromArgb(60,60,60)
#create form
$form = New-Object System.Windows.Forms.Form
$form.SuspendLayout()
$form.WindowState = [System.Windows.Forms.FormWindowState]::Maximized
$form.ShowInTaskbar = $false
$form.MaximizeBox = $false
$form.Opacity = 0.5
$form.ControlBox = $false
$form.FormBorderStyle = [System.Windows.Forms.FormBorderStyle]::none
#create Tablelayout panel on this form
$TableLayoutPanel = New-Object System.Windows.Forms.TableLayoutPanel
$TableLayoutPanel.SuspendLayout()
$TableLayoutPanel.ColumnCount=1
$TableLayoutPanel.RowCount=1
$TableLayoutPanel.Dock=[System.Windows.Forms.DockStyle]::Fill
$form.Controls.Add($TableLayoutPanel)
#create button on this tablelayoutpanel
$shutdownBtn = New-Object System.Windows.Forms.Button
$shutdownBtn.Size = New-Object System.Drawing.Size(200,40)
$shutdownBtn.Text = "Shut down"
$shutdownBtn.FlatStyle = "Flat"
$shutdownBtn.UseVisualStyleBackColor = $True
$shutdownBtn.BackColor = $windowsGreyOff
$shutdownBtn.FlatAppearance.BorderSize = 0
$shutdownBtn.ForeColor =[System.Drawing.Color]::White
$shutdownBtn.Font = "Segoe UI,10pt"
$shutdownBtn.Anchor=[System.Windows.Forms.AnchorStyles]::None
$TableLayoutPanel.Controls.Add($shutdownBtn)
#Layout
$TableLayoutPanel.ResumeLayout($false)
$form.ResumeLayout($false)
$shutdownBtn.Add_Click({
try {
}
catch{
}
})
#change color to tablelayot on first show
$form.Add_Shown({
$TableLayoutPanel.BackColor =$windowsGreyTrans
})
$TableLayoutPanel.Add_Click({
$form.close()
})
$shutdownBtn.Add_MouseEnter({
$this.BackColor = $windowsGreyOn
})
$shutdownBtn.Add_MouseLeave({
$this.BackColor = $windowsGreyOff
})
[void]$form.ShowDialog()
$form.Dispose()
