示例

下面的代码示例演示如何使用SizingGripStatusBarPanel.AlignmentStatusBarPanel.WidthStatusBarPanel.AutoSizeStatusBarPanel.BorderStyle成员以及如何处理PanelClick事件。The following code example demonstrates how to use the SizingGrip, StatusBarPanel.Alignment, StatusBarPanel.Width, StatusBarPanel.AutoSize, and StatusBarPanel.BorderStyle members and how to handle the PanelClick event.

若要运行该示例,请将以下代码粘贴到窗体中。To run the example, paste the following code in a form. 在窗体的构造函数或Load方法中调用方法。InitializeStatusBarPanelsCall the InitializeStatusBarPanels method in the form's constructor or Load method.
