Nell'esempio di codice seguente viene creato un controllo StatusBar in un form e vengono aggiunti due oggetti StatusBarPanel.The following code example creates a StatusBar control on a form and adds two StatusBarPanel objects. Uno degli oggetti StatusBarPanel, denominato panel1, Visualizza il testo di stato di un'applicazione.One of the StatusBarPanel objects, named panel1, displays status text for an application. Il secondo oggetto StatusBarPanel, denominato panel2, Visualizza la data corrente e usa la proprietà ToolTipText della classe StatusBarPanel per visualizzare l'ora corrente.The second StatusBarPanel object, named panel2, displays the current date and uses the ToolTipText property of the StatusBarPanel class to display the current time. Nell'esempio viene utilizzata la proprietà ShowPanels per assicurarsi che i pannelli siano visualizzati anziché un pannello standard e che utilizzi e la proprietà Panels per accedere al metodo Add del StatusBar.StatusBarPanelCollection per aggiungere i pannelli a StatusBar.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. Nell'esempio vengono inoltre utilizzate le proprietà AutoSize, BorderStyle, ToolTipText e Text per inizializzare gli oggetti StatusBarPanel.The example also uses the AutoSize, BorderStyle, ToolTipText, and Text properties to initialize the StatusBarPanel objects. Questo esempio richiede che il metodo definito nell'esempio venga definito e chiamato dal costruttore di un Form.This example requires that the method defined in the example is defined and called from the constructor of a Form.

private:
   void CreateMyStatusBar()
   {
      // Create a StatusBar control.
      StatusBar^ statusBar1 = gcnew StatusBar;

      // Create two StatusBarPanel objects to display in the StatusBar.

Ogni pannello visualizzato dal controllo StatusBar è un'istanza della classe StatusBarPanel.Each panel displayed by the StatusBar control is an instance of the StatusBarPanel class. La proprietà Panels consente di ottenere un riferimento alla raccolta di oggetti StatusBarPanel attualmente archiviati nel controllo StatusBar.The Panels property enables you to obtain a reference to the collection of StatusBarPanel objects that are currently stored in the StatusBar control. Con questo riferimento, è possibile aggiungere pannelli, rimuovere pannelli, accedere a un pannello specifico all'interno della raccolta e ottenere un conteggio dei pannelli nel controllo StatusBar.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.
