Class FormSpec

    java.lang.Object
      com.jgoodies.forms.layout.FormSpec

All Implemented Interfaces:
  Serializable

Direct Known Subclasses:
  ColumnSpec, RowSpec

    public abstract class FormSpec

extends Object
implements Serializable

An abstract class that specifies columns and rows in FormLayout by their default alignment, start size and resizing behavior. API users will use the subclasses `ColumnSpec` and `RowSpec`.

Nested Class Summary
`static class` | `FormSpec.DefaultAlignment` An ordinal-based serializable typesafe enumeration for the column and row default alignment types.

Field Summary
`static double` | `DEFAULT_GROW` The default resize weight.
`static double` | `NO_GROW` Gives a column or row a fixed size.

Constructor Summary
`protected` | `FormSpec(FormSpec.DefaultAlignment defaultAlignment, Size size, double resizeWeight)` Constructs a `FormSpec` for the given default alignment, size, and resize weight.
`protected` | `FormSpec(FormSpec.DefaultAlignment defaultAlignment, String encodedDescription)` Constructs a `FormSpec` from the specified encoded description.

Method Summary
`FormSpec.DefaultAlignment` | `getDefaultAlignment()` Returns the default alignment.
`double` | `getResizeWeight()` Returns the current resize weight.
`Size` | `getSize()` Returns the size.
`String` | `toShortString()` Returns a string representation of this form specification.
`String` | `toString()` Returns a string representation of this form specification.

Field Detail

### NO_GROW

    public static final double NO_GROW

  Gives a column or row a fixed size.

  See Also:
    Constant Field Values

### DEFAULT_GROW

    public static final double DEFAULT_GROW

  The default resize weight.

  See Also:
    Constant Field Values

Constructor Detail

### FormSpec

    protected FormSpec(FormSpec.DefaultAlignment defaultAlignment,
                       Size size,
                       double resizeWeight)

  Constructs a `FormSpec` for the given default alignment, size, and resize weight. The resize weight must be a non-negative double; you can use `NONE` as a convenience value for no resize.

  Parameters:
    `defaultAlignment` - the spec's default alignment
    `size` - a constant, component or bounded size
    `resizeWeight` - the spec resize weight
  Throws:
    `IllegalArgumentException` - if the resize weight is negative

### FormSpec

    protected FormSpec(FormSpec.DefaultAlignment defaultAlignment,
                       String encodedDescription)

  Constructs a `FormSpec` from the specified encoded description. The description will be parsed to set initial values.

  Parameters:
    `defaultAlignment` - the default alignment
    `encodedDescription` - the encoded description

Method Detail

### getDefaultAlignment

    public final FormSpec.DefaultAlignment getDefaultAlignment()

  Returns the default alignment.

  Returns:
    the default alignment

### getSize

    public final Size getSize()

  Returns the size.

  Returns:
    the size

### getResizeWeight

    public final double getResizeWeight()

  Returns the current resize weight.

  Returns:
    the resize weight.

### toString

    public final String toString()

  Returns a string representation of this form specification. The string representation consists of three elements separated by a colon (`":"`), first the alignment, second the size, and third the resize spec.

  This method does not return a decoded version of this object; the contrary is the case. Many instances will return a string that cannot be parsed.

  Note: The string representation may change at any time. It is strongly recommended to not use this string for parsing purposes.

  Overrides:
    `toString` in class `Object`
  Returns:
    a string representation of the form specification.

### toShortString

    public final String toShortString()

  Returns a string representation of this form specification. The string representation consists of three elements separated by a colon (`":"`), first the alignment, second the size, and third the resize spec.

  This method does not return a decoded version of this object; the contrary is the case. Many instances will return a string that cannot be parsed.

  Note: The string representation may change at any time. It is strongly recommended to not use this string for parsing purposes.

  Returns:
    a string representation of the form specification.
