接上期的内容,此次读取view的下一层几subview
主要用到下面的方法获取view的第一个子级
一个封装的函数
''' <summary>
''' 获取当前视图的全部的子视图的句柄
''' </summary>
''' <param name="draftApp">MarDrafting对象</param>
''' <param name="viewHandle">视图的句柄</param>
''' <returns>子视图句柄的list集合</returns>
Public Shared Function ViewSubViews(draftApp As MarDrafting, viewHandle As MarElementHandle) As List(Of MarElementHandle)
If Not draftApp.ElementIsView(viewHandle) Then
Return Nothing
End If
Dim rtns As New List(Of MarElementHandle)
Try
Dim subvh As MarElementHandle
subvh = draftApp.ElementChildFirstGet(viewHandle)
rtns.Add(subvh)
'读取第2个view
Dim nextsubVh As MarElementHandle
Try
nextsubVh = draftApp.ElementSiblingNextGet(subvh)
rtns.Add(nextsubVh)
Catch ex As Exception
End Try
Dim errFlag As Boolean = True
Do
Try
nextsubVh = draftApp.ElementSiblingNextGet(nextsubVh)
rtns.Add(nextsubVh)
Catch ex As Exception
errFlag = False
End Try
Loop While errFlag
Catch ex As Exception
MsgBox(ex.StackTrace)
End Try
Return rtns
End Function主函数，也就文章刚开始看到的结果
