<h1>:: Reference :: Columns & Rows ::</h1>
Columns and rows are specified by three parts:
<ul>
<li>a mandatory initial size
<li>an optional default alignment
<li>an optional resizing behavior
</ul>
For example, you can specify that a column is left aligned,
has an initial size of 50 Dialog Units and grows:
<tt>new ColumnSpec("left:50dlu:grow");</tt>
<h2>Resizing Behavior</h2>
Columns and rows can grow if the layout container becomes larger
than the preferred size. By default, columns and rows wont resize.
The extra space is distributed over the columns and rows that
have a resize weight larger than 0.0, where each column gets a space
proportional to its weight.
<h2>String Representations</h2>
String representations for column and row specifications
can be used in the FormLayout constructors as well as in classes
<tt>ColumnSpec</tt>, <tt>RowSpec</tt>.
<pre>
columnSpec ::= [columnAlignment:] size [:resizeBehavior]
rowSpec ::= [rowAlignment :] size [:resizeBehavior]
resizeBehavior ::= NONE | GROW | GROW(<double>) | G(<double>)
</pre>
<h2>Examples</h2><pre>
new ColumnSpec("16px");
new ColumnSpec("left:16px");
new ColumnSpec("left:16px:grow");
new FormLayout("right:max(50dlu;pref), 4dlu, max(100dlu;min)",
"p, 3dlu, p, 3dlu, fill:200dlu:grow");
</pre>
