AbstractDragTabsEventHandler.DragState onDrag(AbstractDragTabsEventHandler.DragState dragState,
                                              float dragDistance)
```
    The method, which is invoked in order to calculate the positions of all tabs, depending on the current drag distance.
    
    Parameters:
    
    dragState - The current drag state as a value of the enum AbstractDragTabsEventHandler.DragState. The drag state must either be AbstractDragTabsEventHandler.DragState.DRAG_TO_END or AbstractDragTabsEventHandler.DragState.DRAG_TO_START
    
    dragDistance - The current drag distance in pixels as a Float value
    
    Returns:
    
    A drag state, which specifies whether the tabs are overshooting, or not. If the tabs are overshooting, the drag state must be AbstractDragTabsEventHandler.DragState.OVERSHOOT_START or AbstractDragTabsEventHandler.DragState.OVERSHOOT_END, null otherwise
  - onPressStarted
```
void onPressStarted(AbstractItem item)

  - onPressEnded
```
void onPressEnded(AbstractItem item)
```
    The method, which is invoked, when pressing a view has been ended.

  - onClick
```
void onClick(AbstractItem item)
```
    The method, which is invoked, when a view has been clicked.
    
    Parameters:
    
    item - The item, which corresponds to the view, which has been clicked, as an instance of the class AbstractItem. The item may not be null
  - onFling
```
void onFling(float distance,
             long duration)
```
    The method, which is invoked, when a fling has been triggered.
    
    Parameters:
