示例

下面的代码示例演示了此成员的用法。 在此示例中,事件处理程序报告事件的发生情况 ToolStripRenderer.RenderArrow 。 此报表可帮助你了解事件发生的时间,并可以帮助你进行调试。

若要运行示例代码,请将其粘贴到包含继承自 ToolStripRenderer的类型实例(如 ToolStripSystemRendererToolStripProfessionalRenderer)的项目中。 然后命名实例 ToolStripRenderer1 并确保事件处理程序与事件 ToolStripRenderer.RenderArrow 相关联。

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
