public class ScrollFrame
extends DragControl
implements PreRenderable, Renderable
```
A frame that can scroll its contents. The frame can be interactively resized by dragging the border, and be moved by dragging the frame or title bar. The frame can be minimized. The frame displays scroll bars if the size of the content exceeds the size of the frame, and optionally displays a title bar with a text string and an icon.
The frame renders its contents into a texture, and then draws the texture when the frame is rendered. This provides good performance for content that is expensive to draw, and changes infrequently. If the frame is sized so large that the visible portion of the contents cannot be rendered into a single texture, then the contents will be drawn directly when the frame is rendered.

public void setMinimizedSize(Size size)
```
    Specifies the size of the minimized tree frame. This size is used when the tree is minimized or animating. An animation can use this field to manipulate the size of the frame as the animation runs without interfering with the frame's normal maximized size.
    
    Parameters:
    
    size - the size of the minimized frame. Set null to use the same size in maximized and minimized states.
  - setScreenLocation
```
public void setScreenLocation(Offset screenLocation)
```
    Set the location of the upper left corner of the tree, measured in screen coordinates with the origin at the upper left corner of the screen.
    
    Parameters:
    
    screenLocation - New screen location.
  - setSize
```
public void setSize(Size size)
```
    Set the size of the frame. The size determines the size of the frame when the frame is maximized.
    
    Parameters:
    
    size - New size.

  - setTitleBarHeight
```
public void setTitleBarHeight(int titleBarHeight)
```
    Specifies the height, in pixels, of the frame title bar.
    
    Parameters:
    
    titleBarHeight - new height, in pixels.
  - stepAnimation
```
protected void stepAnimation(DrawContext dc)
```
    Increment the active animation. Has no effect if there is no active animation. This method must be called once per frame.
    
    Parameters:
    
    dc - Current draw context.
  - updateBounds
```
public void updateBounds(DrawContext dc)
```
    Compute the bounds of the content frame, and the extents of the scroll range. Calling this method updates the frame and scroll model to match the size of the scrollable content. Bounds are only computed once per frame. Multiple calls in the same frame will not change the computed bounds.
    
    Parameters:
    
    dc - Current draw context.
  - updateTile
```
protected void updateTile(DrawContext dc,
                          gov.nasa.worldwind.util.tree.ScrollFrame.ContentTile tile,
                          Rectangle tileBounds)
```
    Draws the current list of ScrollableTiles into the texture tiles. The tiles are updated when necessary.
    
    Parameters:
    
    dc - the draw context the tile relates to.
    
    tile - the tile to update. A new texture tile will be allocated for the tile, if the tile does not have a texture.
    
    tileBounds - bounds of the tile being updated, within the larger texture.
  - updateTiles
```
protected void updateTiles(DrawContext dc)
```
    Update content tiles that have been rendered to a texture.
    
    Parameters:
    
    dc - Current draw context.
