| Microsoft DirectX 8.1 (C++) |
The AMTimelineComp.GetRecursiveLayerOfType method performs a depth-first ordering of the virtual tracks contained in this composition, and retrieves the nth virtual track from that ordering.
Syntax
object.GetRecursiveLayerOfType(
ppVirtualTrack As AMTimelineObj,
WhichLayer As Long,
Type As TIMELINE_MAJOR_TYPE
)
Parameters
ppVirtualTrack
AMTimelineObj object that receives the virtual track.
WhichLayer
Value that specifies which virtual track to retrieve, indexed from zero.
Type
Member of the TIMELINE_MAJOR_TYPE enumerated type that specifies whether to include tracks in the search.
Error Codes
If the method fails, an error is raised, and Err.Number can be set to the following value:
| Value | Description |
| E_INVALIDARG | No object of the specified type. |
Remarks
Typically, an application will not need to call this method.
If the Type parameter is TIMELINE_MAJOR_TYPE_TRACK, the depth-first ordering includes tracks. If not, it includes only compositions and groups. The object itself is included in the ordering.
For example, in the following arrangement, starting from Composition A, the ordering would be B, C, F, D, E, A.
