TArrayView< const TWeakPtr< STrackLane > > GetChildLanes()

   MVVM/Views/STrackLane.h  

TViewModelPtr< IOutlinerExtension > GetOutlinerItem()

 Gets the outliner view-model that created this track lane MVVM/Views/STrackLane.h  

TSharedPtr< STrackLane > GetParentLane()

   MVVM/Views/STrackLane.h  

TSharedPtr< FTimeToPixel > GetTimeToPixel()

float GetVerticalPosition()

 Gets the vertical offset of this track lane MVVM/Views/STrackLane.h  

bool IsPinned()

 Returns whether the outliner item that created this track lane is pinned or not MVVM/Views/STrackLane.h  

void PositionParentTrackLanes ( TViewModelPtr< IOutlinerExtension > InItem,
float InItemTop
)

 Sets the vertical offset of this track lane and all parent track lanes given the vertical offset of a particular outliner item inside the current track lane (i.e. an outliner item that's a child of the item that created this track lane) Note that the given item could actually be the one that created this track lane. MVVM/Views/STrackLane.h  

void SetVerticalPosition ( float InPosition
)

 Sets the vertical offset of this track lane MVVM/Views/STrackLane.h
