範例

下列程式碼範例示範如何使用這個成員。The following code example demonstrates the use of this member. 在此範例中,事件處理常式會報告 Paint 事件的發生。In the example, an event handler reports on the occurrence of the Paint event. 此報表可協助您瞭解事件發生的時間,並可協助您進行調試。This report helps you to learn when the event occurs and can assist you in debugging.

若要執行範例程式碼,請將它貼入包含繼承自 ToolStripItem之類型實例的專案,例如 ToolStripButtonToolStripMenuItemTo run the example code, paste it into a project that contains an instance of a type that inherits from ToolStripItem, such as a ToolStripButton or ToolStripMenuItem. 然後將實例命名為 ToolStripItem1,並確定事件處理常式與 Paint 事件相關聯。Then name the instance ToolStripItem1 and ensure that the event handler is associated with the Paint event.

private void ToolStripItem1_Paint(Object sender, PaintEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ClipRectangle", e.ClipRectangle );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Paint Event" );
}
Private Sub ToolStripItem1_Paint(sender as Object, e as PaintEventArgs) _ 
     Handles ToolStripItem1.Paint

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

End Sub
