Splitter.SplitterMoving Splitter.SplitterMoving Splitter.SplitterMoving Splitter.SplitterMoving Event

定义

当拆分器控件正处在移动过程中发生。Occurs when the splitter control is in the process of moving. SplitterMoving 已被 SplitterMoving 取代,且仅为与早期版本兼容而提供。SplitterMoving has been replaced by SplitterMoving and is provided only for compatibility with previous versions.

public:
 event System::Windows::Forms::SplitterEventHandler ^ SplitterMoving;
public event System.Windows.Forms.SplitterEventHandler SplitterMoving;
member this.SplitterMoving : System.Windows.Forms.SplitterEventHandler 
Public Custom Event SplitterMoving As SplitterEventHandler 

示例

下面的代码示例演示如何使用此成员。The following code example demonstrates the use of this member. 在此示例中, 事件处理程序报告SplitterMoving事件的发生。In the example, an event handler reports on the occurrence of the SplitterMoving 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MessageBox.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 MessageBox.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Splitter Splitter1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 Splitter named Splitter1. 然后, 确保事件处理程序与SplitterMoving事件相关联。Then ensure that the event handler is associated with the SplitterMoving event.

private void Splitter1_SplitterMoving(Object sender, SplitterEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "X", e.X );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Y", e.Y );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "SplitX", e.SplitX );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "SplitY", e.SplitY );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "SplitterMoving Event" );
}
Private Sub Splitter1_SplitterMoving(sender as Object, e as SplitterEventArgs) _ 
     Handles Splitter1.SplitterMoving

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "X", e.X)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Y", e.Y)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "SplitX", e.SplitX)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "SplitY", e.SplitY)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"SplitterMoving Event")

End Sub

注解

可以为SplitterMoving事件创建事件处理程序, 以便在应用程序中执行重设大小验证。You can create an event handler for the SplitterMoving event to perform resize validation in your application. 例如, Splitter如果控件停靠在TreeView控件的边缘ListViewSplitterMoved控件上, 则可以在事件中编写代码, 以TreeView确定和ListView的最大和/或最大大小已超出控件, 并将控件的大小限制为最小或最大大小。For example, if a Splitter control is docked to the edges of a TreeView control and a ListView control, you can write code in the SplitterMoved event to determine if the minimum and/or maximum size for the TreeView and ListView controls has been exceeded and restrict the resizing of the controls to their minimum or maximum size.
