## ClipContainer.Tracks

### Description

Returns a TrackCollection containing each Track object in the container.

### C# Syntax

    // get accessor
    TrackCollection rtn = ClipContainer.Tracks;

### Examples

#### Python Example

    #
    # This example demonstrates how to create tracks and retrieve all tracks
    # recursively under the ClipContainer using ClipContainer.Tracks.
    #
    # The following hierarchy will be created:
    #
    # Mixer
    #       |
    #   +-Track (an animation track)
    #   |   |
    #   |   +-CompoundClip
    #   |          |
    #   |          +-Track4 (an animation track)
    #   |
    #   +-Track1 (an animation track)
    #   |
    #   +-Track2 (a shape track)
    #   |
    #   +-Track3 (an audio track)
    #
