ToolStripRenderer.RenderToolStripStatusLabelBackground 事件

定义

绘制 ToolStripStatusLabel 的背景。Draws the background of a ToolStripStatusLabel.

public:
 event System::Windows::Forms::ToolStripItemRenderEventHandler ^ RenderToolStripStatusLabelBackground;
public event System.Windows.Forms.ToolStripItemRenderEventHandler RenderToolStripStatusLabelBackground;
member this.RenderToolStripStatusLabelBackground : System.Windows.Forms.ToolStripItemRenderEventHandler 
Public Custom Event RenderToolStripStatusLabelBackground As ToolStripItemRenderEventHandler 

示例

下面的代码示例演示如何使用此成员。The following code example demonstrates the use of this member. 在此示例中,事件处理程序报告 RenderToolStripStatusLabelBackground 事件的发生。In the example, an event handler reports on the occurrence of the RenderToolStripStatusLabelBackground event. 此报表可帮助你了解何时发生事件,并可帮助你进行调试。This report helps you to learn when the event occurs and can assist you in debugging.

若要运行示例代码,请将其粘贴到一个项目中,该项目包含继承自 ToolStripRenderer的类型的实例,如 ToolStripSystemRendererToolStripProfessionalRendererTo run the example code, paste it into a project that contains an instance of a type that inherits from ToolStripRenderer, such as a ToolStripSystemRenderer or ToolStripProfessionalRenderer. 然后,将该实例命名为 ToolStripRenderer1 并确保事件处理程序与 RenderToolStripStatusLabelBackground 事件关联。Then name the instance ToolStripRenderer1 and ensure that the event handler is associated with the RenderToolStripStatusLabelBackground event.

private void ToolStripRenderer1_RenderToolStripStatusLabelBackground(Object sender, ToolStripItemRenderEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToolStrip", e.ToolStrip );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RenderToolStripStatusLabelBackground Event" );
}
Private Sub ToolStripRenderer1_RenderToolStripStatusLabelBackground(sender as Object, e as ToolStripItemRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderToolStripStatusLabelBackground

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Item", e.Item)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ToolStrip", e.ToolStrip)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"RenderToolStripStatusLabelBackground Event")

End Sub
