All Implemented Interfaces:
```
public abstract class Scrollable
extends Inputtable
                    
```
Extensions to Component which allow it to listen to scroll events and scroll itself.

  - setup
```
 Boolean setup(PolyUI polyUI)
```
    give this a PolyUI reference.
    You can also use this method to do some calculations (such as text widths) that are not dependent on other sizes, or operations that require access to PolyUI things, like PolyUI.settings or PolyUI.translator
    this method is called once, and only once.
  - recalculate
```
 Unit recalculate()
```
    Fully recalculate this component's size, and any of its children's positions.
    
    Since:
    
    1.0.7
  - pushScroll
```
 final Boolean pushScroll(Long delta, Renderer renderer)
```
  - popScroll
```
 final Unit popScroll(Renderer renderer)
```
  - accept
```
 Boolean accept(Event event)
```
    called when this component receives an event.
    
    Returns:
    
    true if the event should be consumed (cancelled so no more handlers are called), false otherwise.
  - tryMakeScrolling
```
@Locking(when = "this.shouldScroll && this.hasVisibleSize && this.visibleSize > this.size") final Unit tryMakeScrolling()
```
  - fixVisibleSize
```
 Unit fixVisibleSize()
```
  - rescale0
```
 Unit rescale0(Float scaleX, Float scaleY, Boolean withChildren)
```
    raw rescale method that does not check rawResize and uses the given scale factors directly.
    
    Parameters:
    
    withChildren - if true, this method will also rescale its children.
  - resetScroll
```
 final Unit resetScroll()
```
    reset the initial scroll position to the current position.
    This method should be used if you externally modify the position of this component with scrolling enabled.
