All Implemented Interfaces:

SwingConstants
```
public class IconView
extends View
```
Icon decorator that implements the view interface. The entire element is used to represent the icon. This acts as a gateway from the display-only View implementations to interactive lightweight icons (that is, it allows icons to be embedded into the View hierarchy. The parent of the icon is the container that is handed out by the associated view factory.

```
public IconView(Element elem)
```
    Creates a new icon view that represents an element.
    
    Parameters:
    elem - the element to create a view for
- Method Detail
  - paint
```
public void paint(Graphics g,
         Shape a)
```
    Paints the icon. The real paint behavior occurs naturally from the association that the icon has with its parent container (the same container hosting this view), so this simply allows us to position the icon properly relative to the view. Since the coordinate system for the view is simply the parent containers, positioning the child icon is easy.
    
    Specified by:
    
    paint in class View
    
    Parameters:
    g - the rendering surface to use
    a - the allocated region to render into
    See Also:
    View.paint(java.awt.Graphics, java.awt.Shape)
  - getPreferredSpan
```
public float getPreferredSpan(int axis)
```
    Determines the preferred span for this view along an axis.
    
    Specified by:
    
    getPreferredSpan in class View
    
    Parameters:
    axis - may be either View.X_AXIS or View.Y_AXIS
    
    Returns:
    the span the view would like to be rendered into Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.
    
    Throws:
    
    IllegalArgumentException - for an invalid axis
    See Also:
    View.getPreferredSpan(int)
  - getAlignment
```
public float getAlignment(int axis)
```
    Determines the desired alignment for this view along an axis. This is implemented to give the alignment to the bottom of the icon along the y axis, and the default along the x axis.
    
    Overrides:
    
    getAlignment in class View
    
    Parameters:
    axis - may be either View.X_AXIS or View.Y_AXIS
    
    Returns:
    the desired alignment >= 0.0f && <= 1.0f. This should be a value between 0.0 and 1.0 where 0 indicates alignment at the origin and 1.0 indicates alignment to the full span away from the origin. An alignment of 0.5 would be the center of the view.
  - modelToView
```
public Shape modelToView(int pos,
                Shape a,
                Position.Bias b)
                  throws BadLocationException
```
    Provides a mapping from the document model coordinate space to the coordinate space of the view mapped to it.
    Specified by:
    
    modelToView in class View
    
    Parameters:
    pos - the position to convert >= 0
    a - the allocated region to render into
    b - the bias toward the previous character or the next character represented by the offset, in case the position is a boundary of two views; b will have one of these values:
    
    Position.Bias.Forward
    Position.Bias.Backward
    Returns:
    the bounding box of the given position
    
    Throws:
    
    BadLocationException - if the given position does not represent a valid location in the associated document
    See Also:
    View.modelToView(int, java.awt.Shape, javax.swing.text.Position.Bias)
  - viewToModel
```
public int viewToModel(float x,
              float y,
              Shape a,
              Position.Bias[] bias)
```
    Provides a mapping from the view coordinate space to the logical coordinate space of the model.
    
    Specified by:
    
    viewToModel in class View
    
    Parameters:
    x - the X coordinate >= 0
    y - the Y coordinate >= 0
    a - the allocated region to render into
    
    Returns:
    the location within the model that best represents the given point of view >= 0
    See Also:
    View.viewToModel(float, float, java.awt.Shape, javax.swing.text.Position.Bias[])
