Constructor Details

BoundedSize

public BoundedSize(Size basis,
                   Size lowerBound,
                   Size upperBound)
Constructs a BoundedSize for the given basis using the specified lower and upper bounds.
Parameters:
basis - the base size
lowerBound - the lower bound size
upperBound - the upper bound size
Since:
1.1

Method Details

compressible

public 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.

BoundedSizes are compressible if the base Size is compressible.

Specified by:
compressible in interface Size
Returns:
true if and only if the basis is compressible
Since:
1.1

encode

public String encode()
Returns a parseable string representation of this bounded size.
Specified by:
encode in interface Size
Returns:
a String that can be parsed by the Forms parser
Since:
1.2

equals

public boolean equals(Object object)
Indicates whether some other BoundedSize is "equal to" this one.
Parameters:
object - the object with which to compare
Returns:
true if this object is the same as the object argument, false otherwise.
See Also:
Object.hashCode(), java.util.Hashtable

getBasis

public Size getBasis()
Returns the base size, which is not-null.
Returns:
the base size
Since:
1.1

getLowerBound

public Size getLowerBound()
Returns the optional lower bound.
Returns:
the optional lower bound
Since:
1.1

getUpperBound

public Size getUpperBound()
Returns the optional upper bound.
Returns:
the optional upper bound
Since:
1.1

hashCode

public int hashCode()
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.
Returns:
a hash code value for this object.
See Also:
Object.equals(Object), java.util.Hashtable

maximumSize

public int maximumSize(Container container,
                       List components,
                       FormLayout.Measure minMeasure,
                       FormLayout.Measure prefMeasure,
                       FormLayout.Measure defaultMeasure)
Returns this size as pixel size. Neither requires the component list nor the specified measures. Honors the lower and upper bound.

Invoked by FormSpec to determine the size of a column or row.

Specified by:
maximumSize in interface Size
Parameters:
container - the layout container
components - the list of components to measure
minMeasure - the measure used to determine the minimum size
prefMeasure - the measure used to determine the preferred size
defaultMeasure - the measure used to determine the default size
Returns:
the maximum size in pixels
See Also:
FormSpec.maximumSize(Container, List, FormLayout.Measure, FormLayout.Measure, FormLayout.Measure)

toString

public String toString()
Returns:
a string representation of this bounded size
