Examples

The following code example creates a StatusBar control on a form and adds two StatusBarPanel objects. One of the StatusBarPanel, named panel1, displays status text for an application. The second StatusBarPanel, named panel2, displays the current date and uses the ToolTipText property of the StatusBarPanel class to display the current time. 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. The example also uses the AutoSize, BorderStyle, ToolTipText, and Text properties to initialize the StatusBarPanel objects. This example assumes 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...";

      // 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;

      // Create ToolTip text that displays the time the application
      // was started.
      panel2->ToolTipText = System::DateTime::Now.ToShortTimeString();

      // Set the text of the panel to the current date.
      panel2->Text = "Started: " + System::DateTime::Today.ToLongDateString();

      // Set the AutoSize property to size the panel to the size of the contents.
      panel2->AutoSize = StatusBarPanelAutoSize::Contents;

Remarks

The StatusBar.StatusBarPanelCollection class stores the panels displayed in the StatusBar. Each object in the collection is an instance of the StatusBarPanel class which defines the display characteristics and behaviors of a panel displayed in a StatusBar.

There are a number of ways to add panels to the collection. The Add method provides the ability to add a single panel to the collection. To add a number of panels to the collection, you create an array of StatusBarPanel objects and assign it to the AddRange method. If you want to insert a panel at a specific location within the collection, you can use the Insert method. To remove panels, you can use either the Remove method or the RemoveAt method if you know where the panel is located within the collection. The Clear method enables you to remove all panels from the collection instead of using the Remove method to remove a single panel at a time.

In addition to methods and properties for adding and removing panels, the StatusBar.StatusBarPanelCollection also provides methods to find panels within the collection. The Contains method enables you to determine whether a panel is a member of the collection. Once you know that the panel is located within the collection, you can use the IndexOf method to determine where the panel is located within the collection.
