ToolStripRenderer.RenderToolStripPanelBackground 事件

定义

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

public:
 event System::Windows::Forms::ToolStripPanelRenderEventHandler ^ RenderToolStripPanelBackground;
public event System.Windows.Forms.ToolStripPanelRenderEventHandler RenderToolStripPanelBackground;
member this.RenderToolStripPanelBackground : System.Windows.Forms.ToolStripPanelRenderEventHandler 
Public Custom Event RenderToolStripPanelBackground As ToolStripPanelRenderEventHandler 

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 RenderToolStripPanelBackground 事件的发生。In the example, an event handler reports on the occurrence of the RenderToolStripPanelBackground 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 RenderToolStripPanelBackground 事件关联。Then name the instance ToolStripRenderer1 and ensure that the event handler is associated with the RenderToolStripPanelBackground event.

private void ToolStripRenderer1_RenderToolStripPanelBackground(Object sender, ToolStripPanelRenderEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToolStripPanel", e.ToolStripPanel );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RenderToolStripPanelBackground Event" );
}
Private Sub ToolStripRenderer1_RenderToolStripPanelBackground(sender as Object, e as ToolStripPanelRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderToolStripPanelBackground

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

End Sub
