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panel2为的, 它显示ToolTipText当前日期, 并StatusBarPanel使用类的属性来显示当前时间。The second StatusBarPanel, 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

默认情况下, StatusBar控件在没有任何面板的Text情况下显示其属性的值。By default, the StatusBar control displays the value of its Text property without any panels. ShowPanels设置为true时, 将StatusBarPanel显示在StatusBar控件中指定的任何对象。When ShowPanels is set to true, any StatusBarPanel objects specified in the StatusBar control are displayed. 创建StatusBar类的实例时, 最初不创建任何面板。No panels are initially created when you create an instance of the StatusBar class. 您可以StatusBar StatusBar.StatusBarPanelCollection使用类的方法将面板添加到控件。AddYou can add panels to a StatusBar control by using the Add method of the StatusBar.StatusBarPanelCollection class. 可以通过的Panels StatusBar属性访问此集合类。This collection class can be accessed through the Panels property of StatusBar.
