ToolStripItemImageRenderEventArgs 类

定义

RenderItemImage 事件提供数据。Provides data for the RenderItemImage event.

public ref class ToolStripItemImageRenderEventArgs : System::Windows::Forms::ToolStripItemRenderEventArgs
public class ToolStripItemImageRenderEventArgs : System.Windows.Forms.ToolStripItemRenderEventArgs
type ToolStripItemImageRenderEventArgs = class
    inherit ToolStripItemRenderEventArgs
Public Class ToolStripItemImageRenderEventArgs
Inherits ToolStripItemRenderEventArgs
继承
ToolStripItemImageRenderEventArgs

示例

下面的代码示例演示如何使用此类型。The following code example demonstrates the use of this type. 在此示例中, 事件处理程序报告RenderItemImage事件的发生。In the example, an event handler reports on the occurrence of the RenderItemImage 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RenderItemImage与事件相关联。Then name the instance ToolStripRenderer1 and ensure that the event handler is associated with the RenderItemImage event.

private void ToolStripRenderer1_RenderItemImage(Object sender, ToolStripItemImageRenderEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Image", e.Image );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ImageRectangle", e.ImageRectangle );
messageBoxCS.AppendLine();
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(), "RenderItemImage Event" );
}
Private Sub ToolStripRenderer1_RenderItemImage(sender as Object, e as ToolStripItemImageRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderItemImage

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Image", e.Image)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ImageRectangle", e.ImageRectangle)
    messageBoxVB.AppendLine()
    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(),"RenderItemImage Event")

End Sub
