Values

none → const DiagonalDragBehavior

This behavior will not allow for any diagonal scrolling.

Drag gestures in one direction or the other will lock the input axis until the gesture is released.

weightedEvent → const DiagonalDragBehavior

This behavior will only allow diagonal scrolling on a weighted scale per gesture event.

This means that after initially evaluating the drag gesture, the weighted evaluation (based on kTouchSlop) stands until the gesture is released.

weightedContinuous → const DiagonalDragBehavior

This behavior will only allow diagonal scrolling on a weighted scale that is evaluated throughout a gesture event.

This means that during each update to the drag gesture, the scrolling axis will be allowed to scroll diagonally if it exceeds the kTouchSlop.

free → const DiagonalDragBehavior

This behavior allows free movement in any and all directions when dragging.
