Field Detail

boxColor

public ColorAttribute boxColor

Color of the box. This defaults to white.

colorKey

public StringParameter colorKey

A column name to use as a color key. If this string is non-empty, then it specifies a column name that is used to determine a color for each row. The value in that row and column determines the color via a hash function, so that if two rows are identical in that column, then they are also identical in color. This is a string that defaults to empty, indicating that all rows should be displayed in black.

fields

public Parameter fields

The fields to display in the table. This is an array of strings specifying the field names to display. It defaults to ALL, which indicates that all fields should be displayed.

maxRows

public Parameter maxRows

The maximum number of rows to display. This is an integer, with default value UNBOUNDED.

variableName

public StringParameter variableName

The name of the variable in the container whose value should be displayed in the icon. The variable value must be an array of records. This is a string that defaults to the empty string.

_labelFont

protected static final java.awt.Font _labelFont

The font used.

_HORIZONTAL_PADDING

protected static final double _HORIZONTAL_PADDING

The amount of padding to use around the edges.

See Also:

Constant Field Values

_VERTICAL_PADDING

protected static final double _VERTICAL_PADDING

The amount of padding to use around the edges.
