public:

このメンバーの使用例を次のコード例に示します。The following code example demonstrates the use of this member. この例では、イベントハンドラーがRenderItemImageイベントの発生を報告します。In the example, an event handler reports on the occurrence of the RenderItemImage event. このレポートは、イベントがいつ発生し、デバッグに役立つかを理解するのに役立ちます。This report helps you to learn when the event occurs and can assist you in debugging.

コード例を実行するにToolStripRenderer ToolStripSystemRendererは、やToolStripProfessionalRendererなど、から継承された型のインスタンスを含むプロジェクトに貼り付けます。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. 次に、インスタンスToolStripRenderer1にという名前を付け、イベントハンドラーがRenderItemImageイベントに関連付けられていることを確認します。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
