| ClipSize | Size of the clipping rectangle, outside which content will not be displayed. (Inherited from DecoratorView<T>) |

| DownSprite | Sprite to draw for the down arrow, or right arrow in horizontal orientation. |
| FloatingBounds | Contains the bounds of all floating elements in this view tree, including the current view and all descendants. (Inherited from DecoratorView<T>) |
| ForcedVisibility | Forces the scrollbar to be always visible or always hidden, depending on the value. |
| IsFocusable | Whether or not the view can receive controller focus, i.e. the stick/d-pad controlled cursor can move to this view. Not generally applicable for mouse controls. (Inherited from DecoratorView<T>) |
| Layout | The current layout parameters, which determine how Measure(Vector2) will behave. (Inherited from DecoratorView<T>) |
| Margin | Margins for this view. See Margin. |
| Name | Simple name for this view, used in log/debug output; does not affect behavior. (Inherited from DecoratorView<T>) |
| Opacity | Opacity (alpha level) of the view. (Inherited from DecoratorView<T>) |
| OuterSize | The true computed layout size resulting from a single Measure(Vector2) pass. (Inherited from DecoratorView<T>) |

| PointerStyle | Pointer style to use when this view is hovered. (Inherited from DecoratorView<T>) |
| ScrollWithChildren | If set to an axis, specifies that when any child of the view is scrolled into view (using ScrollIntoView(IEnumerable<ViewChild>, Vector2)), then this entire view should be scrolled along with it. (Inherited from DecoratorView<T>) |
| Tags | The user-defined tags for this view. (Inherited from DecoratorView<T>) |
| ThumbSprite | Sprite to draw for the thumb, which moves within the track and indicates the current scroll position and can be dragged to scroll. |

| UpSprite | Sprite to draw for the up arrow, or left arrow in horizontal orientation. |
| View | (Inherited from ComponentView<T>) |
| Visibility | Drawing visibility for this view. (Inherited from DecoratorView<T>) |
| ZIndex | Z order for this view within its direct parent. Higher indices draw later (on top). (Inherited from DecoratorView<T>) |
Methods
| Name | Description |
|---|---|
| ContainsPoint(Vector2) | Checks if a given point, relative to the view's origin, is within its bounds. (Inherited from DecoratorView<T>) |
| CreateView() | Creates and returns the root view. (Overrides ComponentView<T>.CreateView()) |
| Dispose() | (Inherited from DecoratorView<T>) |
| Draw(ISpriteBatch) | Draws the content for this view. (Inherited from DecoratorView<T>) |
| FocusSearch(Vector2, Direction) | Finds the next focusable component in a given direction that does not overlap with a current position. (Inherited from DecoratorView<T>) |
| GetChildAt(Vector2, Boolean, Boolean) | Finds the child at a given position. (Inherited from DecoratorView<T>) |
| GetChildPosition(IView) | Computes or retrieves the position of a given direct child. (Inherited from DecoratorView<T>) |
| GetChildren(Boolean) | Gets the current children of this view. (Inherited from DecoratorView<T>) |
| GetChildrenAt(Vector2) | Finds all children at a given position. (Inherited from DecoratorView<T>) |
| GetDefaultFocusChild() | Gets the direct child that should contain cursor focus when a menu or overlay containing this view is first opened. (Inherited from DecoratorView<T>) |
| HasOutOfBoundsContent() | Checks if the view has content or elements that are all or partially outside the ActualBounds. (Inherited from DecoratorView<T>) |
| IsDirty() | Checks whether or not the view is dirty - i.e. requires a new layout with a full Measure(Vector2). (Inherited from DecoratorView<T>) |
| IsVisible(Vector2?) | Checks if the view is effectively visible, i.e. if it has anything to draw. (Inherited from DecoratorView<T>) |
| Measure(Vector2) | Performs layout on this view, updating its OuterSize, ActualBounds and ContentBounds, and arranging any children in their respective positions. (Inherited from DecoratorView<T>) |

| OnClick(ClickEventArgs) | Called when a click is received within this view's bounds. (Inherited from DecoratorView<T>) |
| OnDrag(PointerEventArgs) | Called when the view is being dragged (mouse moved while left button held). (Inherited from DecoratorView<T>) |
