Interface Size

All Known Implementing Classes:
BoundedSize, ConstantSize, PrototypeSize

public interface Size
An interface that describes sizes as used by the FormLayout: component measuring sizes, constant sizes with value and unit, and bounded sizes that provide lower and upper bounds for a size.

You can find a motivation for the different Size types in the Forms whitepaper that is part of the product documentation and that is available online too, see http://www.jgoodies.com/articles/forms.pdf.

    • maximumSize

      int maximumSize(Container container, List components, FormLayout.Measure minMeasure, FormLayout.Measure prefMeasure, FormLayout.Measure defaultMeasure)
      Computes and returns this Size's maximum pixel size applied to the given list of components using the specified measures.

      Invoked by FormSpec to determine the size of a column or row. This method is not intended to be called by API users, and it uses API invisible parameter types.

      Parameters:
      container - the layout container
      components - the list of components used to compute the size
      minMeasure - the measure that determines the minimum sizes
      prefMeasure - the measure that determines the preferred sizes
      defaultMeasure - the measure that determines the default sizes
      Returns:
      the maximum size in pixels for the given list of components
    • compressible

      boolean compressible()
      Describes if this Size can be compressed, if container space gets scarce. Used by the FormLayout size computations in #compressedSizes to check whether a column or row can be compressed or not.

      The ComponentSize default is compressible, as well as BoundedSizes that are based on the default size.

      Returns:
      true for compressible Sizes

    • encode

      String encode()
      Returns a String respresentation of this Size object that can be parsed by the Forms parser.

      Implementors should return a non-verbose string.

      Returns:
      a parseable String representation of this object.
