Inventor: DisplayState property of BrowserNodeDefinition.

by Vladimir Ananyev

Issue

BrowserNodeDefinition.DisplayState returns current states for native browser nodes. I find that it returns kDefaultDisplayState unless it was explicitly changed by using BrowserNodeDefinition.DisplayState. Is this assumption correct?

Solution

This is as designed. A return value of kDefaultDisplayState indicates that the browser node’s display state has been decided by Inventor. Other values indicate an override applied by API client. The DisplayState property is intended to be used for browser customization. If you’re interested in state of associated object you need to query the object associated with the browser node.

The following samples illustrate this approach:

VBA:

Sub DumpAdaptivityInfo()

  Dim doc As AssemblyDocument

  Set doc = ThisApplication.ActiveDocument

  Call DumpNodes(doc.BrowserPanes.ActivePane.topNode)

End Sub

Private Sub DumpNodes(topNode As BrowserNode)

  On Error Resume Next

  Dim node As BrowserNode

  For Each node In topNode.BrowserNodes

    Dim nodeDef As NativeBrowserNodeDefinition

    Set nodeDef = node.BrowserNodeDefinition

    Dim nativeObj As Object

    Set nativeObj = nodeDef.NativeObject

    If Not nativeObj Is Nothing Then

      If TypeOf nativeObj Is ComponentOccurrence Then

        Dim occ As ComponentOccurrence

        Set occ = nodeDef.NativeObject

        Debug.Print nodeDef.Label

        Debug.Print Spc(2); "Adaptive: " & occ.Adaptive

      End If

    End If

    Call DumpNodes(node)

  Next
