ToolStripRenderer.RenderArrow ToolStripRenderer.RenderArrow ToolStripRenderer.RenderArrow ToolStripRenderer.RenderArrow Event

定义

在呈现 ToolStripItem 上的箭头时发生。Occurs when an arrow on a ToolStripItem is rendered.

public:
 event System::Windows::Forms::ToolStripArrowRenderEventHandler ^ RenderArrow;
public event System.Windows.Forms.ToolStripArrowRenderEventHandler RenderArrow;
member this.RenderArrow : System.Windows.Forms.ToolStripArrowRenderEventHandler 
Public Custom Event RenderArrow As ToolStripArrowRenderEventHandler 

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RenderArrow事件的发生。In the example, an event handler reports on the occurrence of the RenderArrow 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, 该项目包含从ToolStripRenderer继承的类型的实例, 如ToolStripProfessionalRenderer ToolStripSystemRenderer或。To 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. 然后命名该实例ToolStripRenderer1 , 并确保事件处理程序RenderArrow与事件相关联。Then name the instance ToolStripRenderer1 and ensure that the event handler is associated with the RenderArrow event.

private void ToolStripRenderer1_RenderArrow(Object sender, ToolStripArrowRenderEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ArrowRectangle", e.ArrowRectangle );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ArrowColor", e.ArrowColor );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Direction", e.Direction );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RenderArrow Event" );
}
Private Sub ToolStripRenderer1_RenderArrow(sender as Object, e as ToolStripArrowRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderArrow

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

End Sub
