範例

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。 StatusBarPanel其中一個名為 的物件 panel1 會顯示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。 此範例會使用 ShowPanels 屬性來確保面板會顯示，而不是標準面板，而且會使用 和 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。 這個範例需要定義範例中定義的 方法，並從 的 Form 建構函式呼叫。

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...";

      // Set the AutoSize property to use all remaining space on the StatusBar.
      panel1->AutoSize = StatusBarPanelAutoSize::Spring;

      // Display the second panel with a raised border style.
      panel2->BorderStyle = StatusBarPanelBorderStyle::Raised;

備註

根據預設， StatusBar 控制項會顯示其 Text 屬性的值，而不需要任何面板。 當 設定為 true 時 ShowPanels ，會顯示控制項中指定的 StatusBar 任何 StatusBarPanel 物件。 當您建立 類別的 StatusBar 實例時，一開始不會建立任何面板。 您可以使用 類別的 StatusBar.StatusBarPanelCollection 方法， Add 將面板新增至 StatusBar 控制項。 這個集合類別可以透過 Panels 的 StatusBar 屬性存取。
