Esempi

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 StatusBarPanel, denominato panel2, Visualizza la data corrente e usa la proprietà ToolTipText della classe StatusBarPanel per visualizzare l'ora corrente.The second StatusBarPanel, 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.
      StatusBarPanel^ panel1 = gcnew StatusBarPanel;
      StatusBarPanel^ panel2 = gcnew StatusBarPanel;

      // Display the first panel with a sunken border style.
      panel1->BorderStyle = StatusBarPanelBorderStyle::Sunken;

      // Initialize the text of the panel.
      panel1->Text = "Ready...";

      // was started.
