DocumentCollection对象事件用于响应应用程序中打开的文档。 与对象事件不同,事件在AutoCAD关闭或取消注册之前会保持注册状态。DocumentCollectionDocument 以下事件可用于对象:DocumentCollection
启用 DocumentCollection 对象事件下面的示例使用该事件来指示何时激活绘图窗口。事件发生时,将显示一个消息框,其中包含已激活图形的名称。DocumentActivated VB.NETImports Autodesk.AutoCAD.Runtime Imports Autodesk.AutoCAD.ApplicationServices <CommandMethod("AddDocColEvent")> _ Public Sub AddDocColEvent() AddHandler Application.DocumentManager.DocumentActivated, _ AddressOf docColDocAct End Sub <CommandMethod("RemoveDocColEvent")> _ Public Sub RemoveDocColEvent() RemoveHandler Application.DocumentManager.DocumentActivated, _ AddressOf docColDocAct End Sub Public Sub docColDocAct(ByVal senderObj As Object, _ ByVal docColDocActEvtArgs As DocumentCollectionEventArgs) Application.ShowAlertDialog(docColDocActEvtArgs.Document.Name & _ " was activated.") End Sub C#using Autodesk.AutoCAD.Runtime; using Autodesk.AutoCAD.ApplicationServices; [CommandMethod("AddDocColEvent")] public void AddDocColEvent() { Application.DocumentManager.DocumentActivated += new DocumentCollectionEventHandler(docColDocAct); } [CommandMethod("RemoveDocColEvent")] public void RemoveDocColEvent() { Application.DocumentManager.DocumentActivated -= new DocumentCollectionEventHandler(docColDocAct); } public void docColDocAct(object senderObj, DocumentCollectionEventArgs docColDocActEvtArgs) { Application.ShowAlertDialog(docColDocActEvtArgs.Document.Name + " was activated."); } VBA/ActiveX 代码参考Private Sub AcadDocument_Activate() ' This example intercepts the Document Activate event. MsgBox ThisDrawing.Name & " was activated." End Sub 相关概念父主题: |
