StatusBar.Panels 属性

获取控件中所包含的 StatusBar 面板集合。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms(在 system.windows.forms.dll 中)

语法

声明
<LocalizableAttribute(True)> _
Public ReadOnly Property Panels As StatusBarPanelCollection
用法
Dim instance As StatusBar
Dim value As StatusBarPanelCollection

value = instance.Panels
[LocalizableAttribute(true)] 
public StatusBarPanelCollection Panels { get; }
[LocalizableAttribute(true)] 
public:
property StatusBarPanelCollection^ Panels {
    StatusBarPanelCollection^ get ();
}
/** @property */
public StatusBarPanelCollection get_Panels ()
public function get Panels () : StatusBarPanelCollection

属性值

包含 StatusBar 控件的 StatusBarPanel 对象的 StatusBar.StatusBarPanelCollection

备注

StatusBar 控件可以显示许多面板来向应用程序的用户提供信息。例如,某个面板可以显示当前时间或文件下载的进度。StatusBar 控件所显示的每个面板都是 StatusBarPanel 类的一个实例。Panels 属性使您可以获得对当前存储在 StatusBar 控件中的 StatusBarPanel 对象集合的引用。通过此引用,可以在 StatusBar 控件中添加面板、删除面板、访问集合中的特定面板和获得面板的计数。有关可通过面板集合执行的任务的更多信息,请参见 StatusBar.StatusBarPanelCollection 类参考主题。

示例

下面的代码示例在窗体上创建一个 StatusBar 控件,并添加两个 StatusBarPanel 对象。其中一个 StatusBarPanel 对象名为 panel1,它显示应用程序的状态文本。另一个 StatusBarPanel 对象名为 panel2,它显示当前日期,并使用 StatusBarPanel 类的 ToolTipText 属性显示当前时间。此示例使用 ShowPanels 属性确保显示多个面板而不是一个标准面板,并使用 Panels 属性访问 StatusBar.StatusBarPanelCollectionAdd 方法,以向 StatusBar 中添加面板。该示例还使用 AutoSizeBorderStyleToolTipTextText 属性来初始化 StatusBarPanel 对象。本示例要求示例中定义的方法已定义并且是从 Form 的构造函数中调用的。
