Per-element supported constraints are
percentWidth and percentHeight.
Element's minimum and maximum sizes are always be respected and
where possible, an element's size is limited to less then or equal
of the cell size.
When not explicitly set, the columnWidth property
is calculated as the maximum preferred bounds width of all elements
and the columnHeight property is calculated
as the maximum preferred bounds height of all elements.
When not explicitly set, the columnCount and
rowCount properties are calculated from
any explicit width and height settings for the layout target,
and columnWidth and columnHeight.
In case none is specified, the columnCount and rowCount
values are picked so that the resulting pixel area is as square as possible.
The measured size is calculated from the columnCount, rowCount,
columnWidth, rowHeight properties and the gap sizes.
The default measured size, when no properties were explicitly set, is as square as possible area and is large enough to fit all elements.
In other cases the measured size may not be big enough to fit all elements.
For example, when both columnCount and rowCount are explicitly set to values
such that columnCount * rowCount < element count.
The minimum measured size is calculated the same way as the measured size but it's guaranteed to encompass enough rows and columns along the minor axis to fit all elements.

columnAlign | 속성 |
columnAlign:String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4 |
| 런타임 버전: | Flash Player 10, AIR 1.5 |
Specifies how to justify the fully visible columns to the container width.
ActionScript values can be ColumnAlign.LEFT, ColumnAlign.JUSTIFY_USING_GAP
and ColumnAlign.JUSTIFY_USING_WIDTH.
MXML values can be "left", "justifyUsingGap" and "justifyUsingWidth".
When set to ColumnAlign.LEFT it turns column justification off.
There may be partially visible columns or whitespace between the last column and
the right edge of the container. This is the default value.
When set to ColumnAlign.JUSTIFY_USING_GAP the horizontalGap
actual value increases so that
the last fully visible column right edge aligns with the container's right edge.
In case there is only a single fully visible column, the horizontalGap actual value
increases so that it pushes any partially visible column beyond the right edge
of the container.
Note that explicitly setting the horizontalGap property does not turn off
justification. It only determines the initial gap value.
Justification may increases it.
When set to ColumnAlign.JUSTIFY_USING_WIDTH the columnWidth
actual value increases so that
the last fully visible column right edge aligns with the container's right edge.
Note that explicitly setting the columnWidth property does not turn off justification.
It only determines the initial column width value.
Justification may increases it.
기본값: ColumnAlign.LEFT.

rowAlign | 속성 |
rowAlign:String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4 |

Specifies how to justify the fully visible rows to the container height.
ActionScript values can be RowAlign.TOP, RowAlign.JUSTIFY_USING_GAP
and RowAlign.JUSTIFY_USING_HEIGHT.
MXML values can be "top", "justifyUsingGap" and "justifyUsingHeight".
When set to RowAlign.TOP it turns column justification off.
There might be partially visible rows or whitespace between the last row and
the bottom edge of the container. This is the default value.
When set to RowAlign.JUSTIFY_USING_GAP the verticalGap
actual value increases so that
the last fully visible row bottom edge aligns with the container's bottom edge.
In case there is only a single fully visible row, the value of verticalGap
increases so that it pushes any partially visible row beyond the bottom edge
of the container. Note that explicitly setting the verticalGap does not turn off
justification, but just determines the initial gap value.
Justification can then increases it.
When set to RowAlign.JUSTIFY_USING_HEIGHT the rowHeight
actual value increases so that
the last fully visible row bottom edge aligns with the container's bottom edge. Note that
explicitly setting the rowHeight does not turn off justification, but
determines the initial row height value.
Justification can then increase it.
