    This field is used when the component is smaller than its
display area. It determines where, within the display area, to
place the component.
 There are three kinds of possible values: orientation relative, baseline relative and absolute. Orientation relative values are interpreted relative to the container's component orientation property, baseline relative values are interpreted relative to the baseline and absolute values are not. The absolute values are: CENTER, NORTH, NORTHEAST, EAST, SOUTHEAST, SOUTH, SOUTHWEST, WEST, and NORTHWEST. The orientation relative values are: PAGE_START, PAGE_END, LINE_START, LINE_END, FIRST_LINE_START, FIRST_LINE_END, LAST_LINE_START and LAST_LINE_END. The baseline relative values are: BASELINE, BASELINE_LEADING, BASELINE_TRAILING, ABOVE_BASELINE, ABOVE_BASELINE_LEADING, ABOVE_BASELINE_TRAILING, BELOW_BASELINE, BELOW_BASELINE_LEADING, and BELOW_BASELINE_TRAILING.

    This field is used when the component's display area is larger
than the component's requested size. It determines whether to
resize the component, and if so, how.
 The following values are valid for fill: 

 NONE: Do not resize the component. 
 HORIZONTAL: Make the component wide enough to fill its display area horizontally, but do not change its height. 
 VERTICAL: Make the component tall enough to fill its display area vertically, but do not change its width. 
 BOTH: Make the component fill its display area entirely. 
 The default value is NONE.
