ActivityDesigner.OnConnected(ConnectionPoint, ConnectionPoint) 方法
定义
当在两个连接点之间建立连接时,向 ActivityDesigner 发出通知。Notifies the ActivityDesigner when a connection is established between two connection points.
protected:
virtual void OnConnected(System::Workflow::ComponentModel::Design::ConnectionPoint ^ source, System::Workflow::ComponentModel::Design::ConnectionPoint ^ target);
protected virtual void OnConnected (System.Workflow.ComponentModel.Design.ConnectionPoint source, System.Workflow.ComponentModel.Design.ConnectionPoint target);
abstract member OnConnected : System.Workflow.ComponentModel.Design.ConnectionPoint * System.Workflow.ComponentModel.Design.ConnectionPoint -> unit
override this.OnConnected : System.Workflow.ComponentModel.Design.ConnectionPoint * System.Workflow.ComponentModel.Design.ConnectionPoint -> unit
Protected Overridable Sub OnConnected (source As ConnectionPoint, target As ConnectionPoint)
参数
- source
- ConnectionPoint
当前活动设计器上的源连接点。The source ConnectionPoint on the current activity designer.
- target
- ConnectionPoint
活动设计器上要连接到的目标连接点。The target ConnectionPoint on the activity designer to connect to.
注解
OnConnected 没有默认行为。OnConnected has no default behavior. 若要在两个计器之间建立连接时提供处理,必须在从 ActivityDesigner 派生的类中重写此方法。You must override this method in a class that derives from ActivityDesigner to provide processing when a connection is made between two designers.
