下列程式碼範例會在表單上建立控制項,並新增兩 StatusBarPanel 個 StatusBar 物件。 名為 的第一個 StatusBarPanel 會顯示 panel1
應用程式的狀態文字。 名為 的第二 StatusBarPanel 個 panel2
,會顯示目前的日期,並使用 ToolTipText 類別的 StatusBarPanel 屬性來顯示目前時間。 此範例會 ShowPanels 使用 屬性來確保面板會顯示,而不是標準面板,並使用 Panels 屬性來存取 Add 的 方法 StatusBar.StatusBarPanelCollection ,將面板新增至 StatusBar 。 此範例也會使用 AutoSize 、 BorderStyle ToolTipText 和 Text 屬性來初始化 StatusBarPanel 物件。 這個範例假設範例中定義的方法是由 的建構函式所定義,並從 的 Form 建構函式呼叫。
