StatusBarPanel 构造函数

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

初始化 StatusBarPanel 类的新实例。

public:
 StatusBarPanel();

public StatusBarPanel ();

Public Sub New ()

示例

下面的代码示例在窗体上创建一个控件，并添加两StatusBarPanel个StatusBar对象。 第一个 StatusBarPanel命名 panel1的应用程序显示状态文本。 第二 StatusBarPanel个，命名 panel2，显示当前日期，并使用 ToolTipText 类的属性 StatusBarPanel 显示当前时间。 该示例使用该ShowPanels属性来确保显示面板而不是标准面板，并使用Panels该属性访问Add将面板添加到StatusBar其中的方法StatusBar.StatusBarPanelCollection。 该示例还使用 AutoSize、BorderStyle和ToolTipTextText属性初始化StatusBarPanel对象。 此示例假定在示例中定义的方法是从构造函数中定义的并调用的 Form。
