public class Gap
extends Cell

A gap is a Cell object that represents an empty space between components. Both flexible and fixed gaps may be placed between the components. Typically, this class is not used directly, but by calling the appropriate add methods of a Row or a Column object.

Constructor Detail

Gap

public Gap(int gap,
           boolean isHorizontal)

Creates a fixed gap with the specified orientation.

Parameters:

gap - the length of the gap.

isHorizontal - true for horizontal gap, and false otherwise.

Gap

public Gap(int gap)

Creates a fixed vertical gap.

Parameters:

gap - the length of the gap.

Gap

public Gap(int minGap,
           int preferredGap,
           int maxGap,
           boolean isHorizontal)

Creates a flexible gap with the specified orientation. The flexibility of the gap is indicated by the difference between preferredGap and maxGap. If these arguments are identical, the gap is fixed.

Parameters:

minGap - the minimum length of the gap.

preferredGap - the preferred length of the gap.

maxGap - the maximum length of the gap.

isHorizontal - true for horizontal gap, and false otherwise.

Gap

public Gap(int minGap,
           int preferredGap,
           int maxGap)

Creates a flexible vertical gap. The flexibility of the gap is indicated by the difference between preferredGap and maxGap. If these arguments are identical, the gap is fixed.

Parameters:

minGap - the minimum length of the gap.

preferredGap - the preferred length of the gap.

maxGap - the maximum length of the gap.

Method Detail

toString

public java.lang.String toString()

Returns the string representation of the gap.

Overrides:

toString in class java.lang.Object

Returns:

The string representation of the gap.

computeBoundSpring

Returns the two-dimensional spring associated with this gap.

Specified by:

computeBoundSpring in class Cell

Returns:

The two-dimensional spring associated with this gap.

duplicate

public Cell duplicate(ComponentDuplicator c)

Specified by:

duplicate in class Cell

xmlserialize

public void xmlserialize(XMLPrintStream out,
                         ComponentXMLSerializer c)

Specified by:
