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. 在示例中,事件处理程序报告的匹配项ContentsResized事件。In the example, an event handler reports on the occurrence of the ContentsResized event. 此报告可帮助您了解事件发生的并可以帮助您进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告或频繁发生的事件上多个事件,请考虑更换ShowConsole.WriteLine或将消息附加到多行TextBoxTo report on multiple events or on events that occur frequently, consider replacing Show with Console.WriteLine or appending the message to a multiline TextBox.

若要运行此代码示例,请将其粘贴到包含类型的实例的项目RichTextBox名为RichTextBox1To run the example code, paste it into a project that contains an instance of type RichTextBox named RichTextBox1. 然后,确保事件处理程序相关联ContentsResized事件。Then ensure that the event handler is associated with the ContentsResized event.

private void RichTextBox1_ContentsResized(Object sender, ContentsResizedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "NewRectangle", e.NewRectangle );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ContentsResized Event" );
}
Private Sub RichTextBox1_ContentsResized(sender as Object, e as ContentsResizedEventArgs) _ 
     Handles RichTextBox1.ContentsResized

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

End Sub

注解

接受新的文本所需的边界矩形更改时引发此事件。This event is raised when the bounding rectangle necessary to accept new text changes. 如果文本在控件内的跨多个行,则请求的矩形将始终为控件的宽度。If the text within the control spans multiple lines, the requested rectangle will always be the width of the control. 您可以在控件实现自动调整大小的多行中处理此事件RichTextBox控件。You can handle this event in your control to implement auto-resizing for multiline RichTextBox controls. ContentsResizedEventArgs标识的请求的大小RichTextBoxThe ContentsResizedEventArgs identifies the requested size of the RichTextBox.
