com.jgoodies.forms.layout.ColumnSpec
public final class ColumnSpec
Specifies columns in FormLayout by their default orientation, start size and resizing behavior.
Examples:
The following examples specify a column with FILL alignment, a size of
10 dlu that won't grow.
new ColumnSpec(Sizes.dluX(10));
new ColumnSpec(ColumnSpec.FILL, Sizes.dluX(10), 0.0);
new ColumnSpec(ColumnSpec.FILL, Sizes.dluX(10), ColumnSpec.NO_GROW);
ColumnSpec.parse("10dlu");
ColumnSpec.parse("10dlu:0");
ColumnSpec.parse("fill:10dlu:0");
The FormSpecs provides
predefined frequently used ColumnSpec instances.

Size size,
double resizeWeight)
The resize weight must be a non-negative double; you can use
NO_GROW as a convenience value for no resize.
