Constructors

Name	Description
constructor(EquationNode)	Constructs from a parent object convertible to this.

Properties

Property	Type	Description
groupChr	string	Specifies a symbol(default U+23DF). It is strongly recommended to use attribute ChrType to set accent character. Use this property setting if you cannot find the character you need in a known type.
chrType	EquationCombiningCharacterType	Specify combining characters by type value.
position	EquationCharacterPositionType	This attribute specifies the position of the character in the object
vertJc	EquationCharacterPositionType	This attribute, combined with pos of groupChrPr, specifies the vertical layout of the groupChr object. Where pos specifies the position of the grouping character, vertJc specifies the alignment of the object with respect to the baseline.
startIndex	number	Readonly. Gets the start index of the characters.
length	number	Readonly. Gets the length of the characters.
font	Font	Readonly. Returns the font of this object.
