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. Il primo StatusBarPanel, denominato panel1, Visualizza il testo di stato di un'applicazione.The first StatusBarPanel, 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 la proprietà Panels per accedere al metodo Add della StatusBar.StatusBarPanelCollection per aggiungere i pannelli alla StatusBar.The example uses the ShowPanels property to ensure that the panels are displayed instead of a standard panel, and it uses 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, ToolTipTexte Text per inizializzare gli oggetti StatusBarPanel.The example also uses the AutoSize, BorderStyle, ToolTipText, and Text properties to initialize the StatusBarPanel objects. In questo esempio si presuppone che il metodo definito nell'esempio venga definito e chiamato dal costruttore di un Form.This example assumes that the method defined in the example is defined and called from the constructor of a Form.

Commenti

gli oggetti StatusBarPanel impostati su Contents hanno la precedenza sui pannelli impostati sul valore di Spring.StatusBarPanel objects set to Contents have precedence over those panels set to the Spring value. Ad esempio, un StatusBarPanel con la relativa proprietà AutoSize impostata su Spring viene abbreviato se un StatusBarPanel con la proprietà AutoSize impostata su Contents richiede tale spazio.For example, a StatusBarPanel that has its AutoSize property set to Spring is shortened if a StatusBarPanel with the AutoSize property set to Contents requires that space.

È possibile utilizzare AutoSize per garantire che il contenuto di un StatusBarPanel venga visualizzato correttamente in un controllo StatusBar che contiene più di un pannello.You can use AutoSize to ensure that the contents of a StatusBarPanel are properly displayed in a StatusBar control that contains more than one panel. Ad esempio, potrebbe essere necessario che un pannello che contiene testo venga regolato automaticamente sulla quantità di testo visualizzato (Contents), mentre un altro pannello nel StatusBar che visualizza un indicatore di stato disegnato dal proprietario dovrebbe essere a dimensione fissa (None).For example, you might want a panel that contains text to adjust automatically to the amount of text it is displaying (Contents), while another panel on the StatusBar that displays an owner-drawn progress bar would need to be a fixed size (None).
