如何：向 StatusBar 控件添加面板

项目
08/18/2008

更新：2007 年 11 月

重要说明：
StatusStrip 和 ToolStripStatusLabel 控件替换了 StatusBar 和 StatusBarPanel 控件并添加了功能；但是也可选择保留 StatusBar 和 StatusBarPanel 控件以备向后兼容和将来使用。

StatusBar 控件（Windows 窗体）控件中的可编程区域由 StatusBarPanel 类的实例组成。这些实例是通过添加到 StatusBar.StatusBarPanelCollection 类而添加的。

向状态栏添加面板

在过程中，通过向 StatusBar.StatusBarPanelCollection 添加状态栏面板来创建状态栏面板。使用通过 Panels 属性传递的面板索引指定单个面板的属性设置。

在下面的代码示例中，图标位置的路径设置是 My Documents 文件夹。使用此位置是因为可假定大多数运行 Windows 操作系统的计算机都包含该文件夹。选择此位置还允许具有最低系统访问级别的用户安全地运行应用程序。下面的示例需要一个已添加了 StatusBar 控件的窗体。

说明：
StatusBar.StatusBarPanelCollection 是一个从零开始的集合，因此编写代码时应使用相应的初始值。

Public Sub CreateStatusBarPanels()
' Create panels and set text property.
   StatusBar1.Panels.Add("One")
   StatusBar1.Panels.Add("Two")
   StatusBar1.Panels.Add("Three")
' Set properties of StatusBar panels.
' Set AutoSize property of panels.
   StatusBar1.Panels(0).AutoSize = StatusBarPanelAutoSize.Spring
   StatusBar1.Panels(1).AutoSize = StatusBarPanelAutoSize.Contents
   StatusBar1.Panels(2).AutoSize = StatusBarPanelAutoSize.Contents
' Set BorderStyle property of panels.
   StatusBar1.Panels(0).BorderStyle = StatusBarPanelBorderStyle.Raised
   StatusBar1.Panels(1).BorderStyle = StatusBarPanelBorderStyle.Sunken
   StatusBar1.Panels(2).BorderStyle = StatusBarPanelBorderStyle.Raised
' Set Icon property of third panel. You should replace the bolded
' icon in the sample below with an icon of your own choosing.
   StatusBar1.Panels(2).Icon = New _ 
   System.Drawing.Icon(System.Environment.GetFolderPath _
   (System.Environment.SpecialFolder.Personal) _

   StatusBar1.ShowPanels = True
