ToolStripItem.OnQueryContinueDrag(QueryContinueDragEventArgs) ToolStripItem.OnQueryContinueDrag(QueryContinueDragEventArgs) ToolStripItem.OnQueryContinueDrag(QueryContinueDragEventArgs) ToolStripItem.OnQueryContinueDrag(QueryContinueDragEventArgs) Method

定义

引发 QueryContinueDrag 事件。Raises the QueryContinueDrag event.

protected:
 virtual void OnQueryContinueDrag(System::Windows::Forms::QueryContinueDragEventArgs ^ queryContinueDragEvent);
protected virtual void OnQueryContinueDrag (System.Windows.Forms.QueryContinueDragEventArgs queryContinueDragEvent);
abstract member OnQueryContinueDrag : System.Windows.Forms.QueryContinueDragEventArgs -> unit
override this.OnQueryContinueDrag : System.Windows.Forms.QueryContinueDragEventArgs -> unit
Protected Overridable Sub OnQueryContinueDrag (queryContinueDragEvent As QueryContinueDragEventArgs)

参数

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.

OnQueryContinueDrag 方法还允许派生类对事件进行处理而不必附加委托。The OnQueryContinueDrag 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 OnQueryContinueDrag(QueryContinueDragEventArgs) 时,一定要调用基类的 OnQueryContinueDrag(QueryContinueDragEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnQueryContinueDrag(QueryContinueDragEventArgs) in a derived class, be sure to call the base class's OnQueryContinueDrag(QueryContinueDragEventArgs) method so that registered delegates receive the event.
