属性值

示例

下面的代码示例在窗StatusBar体上创建了一个控件并StatusBarPanel添加了两个对象。The following code example creates a StatusBar control on a form and adds two StatusBarPanel objects. 其中一个名为panel1的对象显示应用程序的状态文本。StatusBarPanelOne of the StatusBarPanel objects, named panel1, displays status text for an application. 第二StatusBarPanel个名为panel2的对象显示ToolTipText当前日期,并StatusBarPanel使用类的属性来显示当前时间。The second StatusBarPanel object, named panel2, displays the current date and uses the ToolTipText property of the StatusBarPanel class to display the current time. ShowPanels示例使用属性来确保显示面板而不是标准面板,并使用Add Panels和属性访问的StatusBar.StatusBarPanelCollection方法以将面板添加到StatusBar中。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AutoSizeBorderStyleToolTipTextText属性对StatusBarPanel对象进行初始化。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Form中定义并调用在此示例中定义的方法。This example requires that the method defined in the example is defined and called from the constructor of a Form.

注解

StatusBar控件可以显示多个面板来向应用程序的用户提供信息。The StatusBar control can display a number of panels to provide information to the user of your application. 例如,面板可能显示当前时间或文件下载进度。For example, a panel could display the current time or the progress of a file download. StatusBar控件显示的每个面板都是StatusBarPanel类的实例。Each panel displayed by the StatusBar control is an instance of the StatusBarPanel class. 属性使你能够获取对当前存储在StatusBar控件中的StatusBarPanel对象的集合的引用。 PanelsThe Panels property enables you to obtain a reference to the collection of StatusBarPanel objects that are currently stored in the StatusBar control. 通过此引用,你可以添加面板、删除面板、访问集合中的特定面板,还可以获取StatusBar控件中的面板的计数。With this reference, you can add panels, remove panels, access a specific panel within the collection, and obtain a count of the panels in the StatusBar control. 有关可以通过 panel 集合执行的任务的详细信息,请参阅StatusBar.StatusBarPanelCollection类参考主题。For more information on the tasks that can be performed with the panel collection, see the StatusBar.StatusBarPanelCollection class reference topics.
