<h1>:: Reference :: Alignments ::</h1>
Column alignments are: <i>left, center, right, fill</i>.<br>
And row alignments are: <i>top, center, bottom, fill</i>.
<p>The <i>fill</i> alignment expands a component to span
its display area, so that the component's left-hand side
is left-aligned, and the right-hand side is right-aligned.
The same applies to top/bottom for rows.
<h2>Applying Defaults</h2>
FormLayout aims to minimize the effort to specificy alignments.
Therefore it 1) tries to reuse alignments, 2) provide good defaults
for form oriented layouts.
<p>1) The column and row alignments are applied to all components
that are located in a single cell of that column/row.
A component can override its column/row alignment by
setting an individual alignment via a <i>CellConstraints</i>
object.
<p>2) By default, the column alignment is set to <i>fill</i>.
The implicit alignment for rows is <i>center</i>.
And so, if you don't specify column and row alignments,
your components will be horizontally filled and vertically centered.
This is a good default for most text fields, combo boxes, buttons
and it works fine with labels too.
<h2>Alignment Constants</h2>
The classes <tt>ColumnSpec</tt>, <tt>RowSpec</tt> provide
constant values for the alignment values mentioned above.
<h2>String Representations</h2>
I recommend to specify column and row alignments in
the FormLayout constructor using string representations.
These strings will be accepted by the <tt>FormLayout</tt>,
<tt>ColumnSpec</tt>, <tt>RowSpec</tt> and <tt>CellConstraints</tt>
classes and by many builder methods.
<pre>
columnAlignment ::= LEFT | CENTER | RIGHT | FILL | L | C | R | F
rowAlignment ::= TOP | CENTER | BOTTOM | FILL | T | C | B | F
</pre>
<h2>Examples</h2><pre>
ColumnSpec.LEFT;
ColumnSpec.FILL;
new ColumnSpec("left");
new ColumnSpec("f");
RowSpec.BOTTOM;
RowSpec.CENTER;
new RowSpec("bottom");
new RowSpec("c");
new FormLayout("left:pref, 4dlu, fill:pref",
" top:pref, 3dlu, center:pref");
new CellConstraints(2, 3, ColumnSpec.LEFT, RowSpec.TOP);
new CellConstraints(2, 3, "left, top");
new CellConstraints(2, 3, "l, t");
CellConstraints cc = new CellConstraints();
builder.add(component, cc.xy(2, 3, "left, top");
