Class MatrixEquationNode

MatrixEquationNode class

This class specifies the Matrix equation, consisting of one or more elements laid out in one or more rows and one or more columns.

public class MatrixEquationNode : EquationNode

Properties

NameDescription
BaseJc { get; set; }This attribute specifies the justification of the matrix. Text outside of the matrix can be aligned with the bottom, top, or center of a matrix function. Default, the matrix assumes center justification.
EquationType { get; }Get the equation type of the current node(Inherited from EquationNode.)
Font { get; }Returns the font of this object.(Inherited from FontSetting.)
IsHidePlaceholder { get; set; }This attribute specifies the Hide Placeholders property on a matrix. When this property is on, placeholders do not appear in the matrix.Default, placeholders do appear such that the locations where text can be inserted are made visible.
Length { get; }Gets the length of the characters.(Inherited from FontSetting.)
ParentNode { get; set; }Specifies the parent node of the current node(Inherited from EquationNode.)
StartIndex { get; }Gets the start index of the characters.(Inherited from FontSetting.)
TextOptions { get; }Returns the text options.(Inherited from FontSetting.)
override Type { get; }Represents the type of the node.(Inherited from EquationNode.)

Methods

AddChild(EquationNodeType)Insert a node of the specified type at the end of the child node list of the current node.(Inherited from EquationNode.)
override Equals(object)Determine whether the current equation node is equal to the specified node
GetChild(int)Returns the node at the specified index among the children of the current node.(Inherited from EquationNode.)
InsertAfter(EquationNodeType)Inserts the specified node after the current node.(Inherited from EquationNode.)
InsertBefore(EquationNodeType)Inserts the specified node before the current node.(Inherited from EquationNode.)
InsertChild(int, EquationNodeType)Inserts a node of the specified type at the specified index position in the current node’s child node list.(Inherited from EquationNode.)
Remove()Removes itself from the parent.(Inherited from EquationNode.)
RemoveAllChildren()Removes all the child nodes of the current node.(Inherited from EquationNode.)
RemoveChild(EquationNode)Removes the specified node from the current node’s children.(Inherited from EquationNode.)
