示例

下面的代码示例在窗体上创建控件 StatusBar 并添加两 StatusBarPanel 个 对象。 其中 StatusBarPanel 一个名为 panel1的对象显示应用程序的状态文本。 第二 StatusBarPanel 个名为 panel2的对象显示当前日期，并使用 ToolTipText 类的 StatusBarPanel 属性显示当前时间。 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 StatusBar.StatusBarPanelCollection 方法，以将面板添加到 StatusBar。 该示例还使用 AutoSize、 BorderStyle、 ToolTipText和 Text 属性来初始化 StatusBarPanel 对象。 此示例要求从 的 Form构造函数定义和调用示例中定义的 方法。

注解

控件 StatusBar 可以显示多个面板，以便向应用程序的用户提供信息。 例如，面板可以显示文件下载的当前时间或进度。 控件显示 StatusBar 的每个面板都是 类的 StatusBarPanel 一个实例。 属性 Panels 使你能够获取对当前存储在 控件中的 对象的集合 StatusBarPanel 的 StatusBar 引用。 使用此引用，可以添加面板、删除面板、访问集合中的特定面板，以及获取控件中的 StatusBar 面板计数。 有关可使用面板集合执行的任务的详细信息，请参阅 StatusBar.StatusBarPanelCollection 类参考主题。
