Eines der StatusBarPanel-Objekte mit dem Namen panel1 zeigt den Status Text für eine Anwendung an.One of the StatusBarPanel objects, named panel1, displays status text for an application. Der zweite StatusBarPanel mit dem Namen panel2 zeigt das aktuelle Datum an und verwendet die ToolTipText-Eigenschaft der StatusBarPanel-Klasse, um die aktuelle Uhrzeit anzuzeigen.The second StatusBarPanel, named panel2, displays the current date and uses the ToolTipText property of the StatusBarPanel class to display the current time. Im Beispiel wird die ShowPanels-Eigenschaft verwendet, um sicherzustellen, dass die Panels anstelle eines Standard Bereichs angezeigt werden, und die Panels-Eigenschaft verwendet, um auf die Add-Methode des StatusBar.StatusBarPanelCollection zuzugreifen, um die Bereiche StatusBar hinzuzufügen.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. Im Beispiel werden auch die AutoSize-, BorderStyle-, ToolTipText-und Text-Eigenschaften verwendet, um die StatusBarPanel-Objekte zu initialisieren.The example also uses the AutoSize, BorderStyle, ToolTipText, and Text properties to initialize the StatusBarPanel objects. Für dieses Beispiel ist es erforderlich, dass die im Beispiel definierte-Methode definiert und vom Konstruktor einer Form aufgerufen wird.This example requires that the method defined in the example is defined and called from the constructor of a Form.
