Constructor Detail

Maligngroup

public Maligngroup(MathBase base)

Creates a math element.

Parameters:

base - The base for the math element tree.

Method Detail

getWidth

public float getWidth()

Return the current width of this element. Initially it's zero, but MathTable after calculating will give it the right value.

Returns:

calculateWidth

public float calculateWidth(Graphics2D g)

Caculates width of the element.

Overrides:

calculateWidth in class AbstractInvisibleJEuclidElement

Parameters:

g - Graphics2D context to use.

Returns:

Width of the element.

setMark

protected void setMark(Malignmark mark)

Parameters:

mark - MathAlignMark

getMark

protected Malignmark getMark()

Returns:

mark

getElementsWholeWidth

protected static float getElementsWholeWidth(Graphics2D g,
                                             List<JEuclidElement> elements)

Parameters:

A string specifying how the alignment group is to be aligned with other alignment groups above or below it. Allowed values are left, right, center, or decimalpoint.

Specified by:

getGroupalign in interface MathMLAlignGroupElement

Returns:

value of the groupalign attribute.

setGroupalign

public void setGroupalign(String groupalign)

setter for the groupalign attribute.

Specified by:

setGroupalign in interface MathMLAlignGroupElement

Parameters:

groupalign - new value for groupalign.
