ContentsResizedEventArgs 类

定义

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

public ref class ContentsResizedEventArgs : EventArgs
public class ContentsResizedEventArgs : EventArgs
type ContentsResizedEventArgs = class
    inherit EventArgs
Public Class ContentsResizedEventArgs
Inherits EventArgs
继承
ContentsResizedEventArgs

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ContentsResized事件的发生。In the example, an event handler reports on the occurrence of the ContentsResized 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. 若要报告多个事件或频繁发生的事件, 请考虑ShowConsole.WriteLine消息替换为多行或将TextBox其追加到多行。To report on multiple events or on events that occur frequently, consider replacing Show with Console.WriteLine or appending the message to a multiline TextBox.

若要运行示例代码, 请将其粘贴到包含名为RichTextBox RichTextBox1的类型的实例的项目中。To run the example code, paste it into a project that contains an instance of type RichTextBox named RichTextBox1. 然后, 确保事件处理程序与ContentsResized事件相关联。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

当接受新文本所需的边界矩形发生更改时, 将引发此事件。This event is raised when the bounding rectangle necessary to accept new text changes. 如果控件中的文本跨多行, 则所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. 可以在控件中处理此事件, 以实现多行RichTextBox控件的自动调整大小。You can handle this event in your control to implement auto-resizing for multiline RichTextBox controls. 标识的请求大小RichTextBoxContentsResizedEventArgsThe ContentsResizedEventArgs identifies the requested size of the RichTextBox.
