Control.OnMouseDoubleClick(MouseEventArgs) 方法

定义

引发 MouseDoubleClick 事件。Raises the MouseDoubleClick event.

protected:
 virtual void OnMouseDoubleClick(System::Windows::Forms::MouseEventArgs ^ e);
protected virtual void OnMouseDoubleClick (System.Windows.Forms.MouseEventArgs e);
abstract member OnMouseDoubleClick : System.Windows.Forms.MouseEventArgs -> unit
override this.OnMouseDoubleClick : System.Windows.Forms.MouseEventArgs -> unit
Protected Overridable Sub OnMouseDoubleClick (e As MouseEventArgs)

参数

e
MouseEventArgs

包含事件数据的 MouseEventArgsAn MouseEventArgs that contains the event data.

注解

引发事件时,将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息,请参阅处理和引发事件For more information, see Handling and Raising Events.

OnMouseDoubleClick 方法还允许派生类对事件进行处理而不必附加委托。The OnMouseDoubleClick method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

继承者说明

在派生类中重写 OnMouseDoubleClick(MouseEventArgs) 时,一定要调用基类的 OnMouseDoubleClick(MouseEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnMouseDoubleClick(MouseEventArgs) in a derived class, be sure to call the base class's OnMouseDoubleClick(MouseEventArgs) method so that registered delegates receive the event.
