示例

下面的代码示例演示如何使用Style属性,StatusBarDrawItemEventHandler委派,请StatusBarDrawItemEventArgs类,StatusBarPanelStyle枚举,和StatusBarDrawItemEventArgs.Panel属性。The following code example demonstrates how to use the Style property, StatusBarDrawItemEventHandler delegate, StatusBarDrawItemEventArgs class, StatusBarPanelStyle enumeration, and StatusBarDrawItemEventArgs.Panel property. 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 into a form. 调用InitializeStatusBarPanels窗体的构造函数中的方法或Load事件方法。Call the InitializeStatusBarPanels method in the form's constructor or Load event-method.

注解

您可以使用此属性指示是否StatusBarPanel显示的文本或是否在面板管理作为一个所有者描述StatusBarPanelYou can use this property to indicate whether a StatusBarPanel displays text or whether the panel is managed as an owner-drawn StatusBarPanel. 若要确定何时StatusBarPanel需要创建的事件处理程序、 绘制DrawItem事件的StatusBar控件。To determine when a StatusBarPanel needs to be drawn, create an event handler for the DrawItem event of the StatusBar control. StatusBarDrawItemEventArgs作为参数传递给事件处理程序的DrawItem事件使您能够确定需要绘制的面板。The StatusBarDrawItemEventArgs passed as a parameter to an event handler of the DrawItem event enables you to determine which panel needs to be drawn. StatusBarDrawItemEventArgs还提供了Graphics对象可以使用上执行绘制任务StatusBarPanelThe StatusBarDrawItemEventArgs also provides a Graphics object you can use to perform drawing tasks on the StatusBarPanel.
