示例
下面的代码示例 StatusBar 在窗体上创建了一个控件并添加了两个 StatusBarPanel 对象。The following code example creates a StatusBar control on a form and adds two StatusBarPanel objects. 其中一个 StatusBarPanel 名为的对象 panel1 显示应用程序的状态文本。One of the StatusBarPanel objects, named panel1, displays status text for an application. 第二个 StatusBarPanel 名为的 panel2 ,它显示当前日期,并使用 ToolTipText 类的属性 StatusBarPanel 来显示当前时间。The second StatusBarPanel, named panel2, displays the current date and uses the ToolTipText property of the StatusBarPanel class to display the current time. 该示例使用 ShowPanels 属性来确保显示面板而不是标准面板,并使用和 Panels 属性访问 Add 的方法 StatusBar.StatusBarPanelCollection 以将面板添加到中 StatusBar 。The example uses the ShowPanels property to ensure that the panels are displayed instead of a standard panel, and it uses and the Panels property to access the Add method of the StatusBar.StatusBarPanelCollection to add the panels to the StatusBar. 该示例还使用 AutoSize 、 BorderStyle 、 ToolTipText 和 Text 属性对对象进行初始化 StatusBarPanel 。The example also uses the AutoSize, BorderStyle, ToolTipText, and Text properties to initialize the StatusBarPanel objects. 此示例要求在的构造函数中定义并调用在此示例中定义的方法 Form 。This example requires that the method defined in the example is defined and called from the constructor of a Form.
