◆ accept()

bool MatrixElement::accept ( ElementVisitor * )

virtual

Visit this element.

An implementation of the visitor pattern.

Implements BasicElement.

Definition at line 329 of file matrixelement.cpp.

void MatrixElement::calcSizes	(	const ContextStyle &	cstyle,
		ContextStyle::TextStyle	tstyle,
		ContextStyle::IndexStyle	istyle,
		StyleAttributes &	style
	)

virtual

Calculates our width and height and our children's parentPosition.

Implements BasicElement.

Definition at line 435 of file matrixelement.cpp.

◆ clone()

virtual MatrixElement * MatrixElement::clone ( )

Reimplemented from BasicElement.

Definition at line 545 of file matrixelement.cpp.

◆ draw()

void MatrixElement::draw	(	TQPainter &	painter,

		ContextStyle::TextStyle	tstyle,
		ContextStyle::IndexStyle	istyle,
		StyleAttributes &	style,
		const LuPixelPoint &	parentOrigin
	)

virtual

Draws the whole element including its children.

The ‘parentOrigin’ is the point this element's parent starts. We can use our parentPosition to get our own origin then.

Implements BasicElement.

Definition at line 515 of file matrixelement.cpp.

◆ elementAt()

SequenceElement * MatrixElement::elementAt	(	uint	row,
		uint	column
	)

Definition at line 1254 of file matrixelement.cpp.

◆ entered()

void MatrixElement::entered ( SequenceElement * child )

virtual

The cursor has entered one of our child sequences.

This is a good point to tell the user where he is.

Reimplemented from BasicElement.

Definition at line 335 of file matrixelement.cpp.

◆ formulaString()

TQString MatrixElement::formulaString ( )

virtual

Reimplemented from BasicElement.

Definition at line 1235 of file matrixelement.cpp.

◆ getColumns()

uint MatrixElement::getColumns ( ) const

inline

Definition at line 201 of file matrixelement.h.

◆ getElementName()

virtual TQString MatrixElement::getElementName ( ) const

inlineprotectedvirtual

Reimplemented from BasicElement.

Definition at line 219 of file matrixelement.h.

◆ getMainChild()

SequenceElement * MatrixElement::getMainChild ( )

virtual

We define the Main Child of a matrix to be the first row/column.

Reimplemented from BasicElement.

Definition at line 713 of file matrixelement.cpp.

◆ getRows()

uint MatrixElement::getRows ( ) const

inline

Definition at line 200 of file matrixelement.h.

◆ getTagName()

virtual TQString MatrixElement::getTagName ( ) const

inlineprotectedvirtual

Returns the tag name of this element type.

Reimplemented from BasicElement.

Definition at line 212 of file matrixelement.h.

◆ goInside()

void MatrixElement::goInside ( FormulaCursor * cursor )

virtual

Sets the cursor inside this element to its start position.

For most elements that is the main child.

Reimplemented from BasicElement.

Definition at line 706 of file matrixelement.cpp.

◆ goToPos()

BasicElement * MatrixElement::goToPos	(	FormulaCursor *	cursor,
		bool &	handled,
		const LuPixelPoint &	point,
		const LuPixelPoint &	parentOrigin
	)

virtual

Sets the cursor and returns the element the point is in.

The handled flag shows whether the cursor has been set. This is needed because only the innermost matching element is allowed to set the cursor.

Reimplemented from BasicElement.

Definition at line 341 of file matrixelement.cpp.

◆ moveDown()

void MatrixElement::moveDown	(	FormulaCursor *	cursor,
		BasicElement *	from
	)

virtual

Enters this element while moving down starting inside the element ‘from’.

Searches for a cursor position inside this element or below it.

Reimplemented from BasicElement.

Definition at line 675 of file matrixelement.cpp.

◆ moveLeft()

void MatrixElement::moveLeft	(	FormulaCursor *	cursor,
		BasicElement *	from
	)

virtual

Enters this element while moving to the left starting inside the element ‘from’.

Searches for a cursor position inside this element or to the left of it.

Reimplemented from BasicElement.

Definition at line 571 of file matrixelement.cpp.

◆ moveRight()

void MatrixElement::moveRight	(	FormulaCursor *	cursor,
		BasicElement *	from
	)

virtual

Enters this element while moving to the right starting inside the element ‘from’.

Searches for a cursor position inside this element or to the right of it.

Reimplemented from BasicElement.

Definition at line 607 of file matrixelement.cpp.

◆ moveUp()

void MatrixElement::moveUp	(	FormulaCursor *	cursor,
		BasicElement *	from
	)

virtual

Enters this element while moving up starting inside the element ‘from’.

Searches for a cursor position inside this element or above it.

Reimplemented from BasicElement.

Definition at line 643 of file matrixelement.cpp.

◆ readAttributesFromDom()

bool MatrixElement::readAttributesFromDom ( TQDomElement element )

protectedvirtual

Definition at line 789 of file matrixelement.cpp.

◆ readAttributesFromMathMLDom()

bool MatrixElement::readAttributesFromMathMLDom ( const TQDomElement & element )

protectedvirtual

Reads our attributes from the MathML element.

Returns false if it failed.

Reimplemented from BasicElement.

Definition at line 861 of file matrixelement.cpp.

bool MatrixElement::readContentFromDom ( TQDomNode & node )

protectedvirtual

Reads our content from the node.

Sets the node to the next node that needs to be read. Returns false if it failed.

Reimplemented from BasicElement.

Definition at line 832 of file matrixelement.cpp.

◆ readContentFromMathMLDom()

int MatrixElement::readContentFromMathMLDom ( TQDomNode & node )

protectedvirtual

Reads our content from the MathML node.

Sets the node to the next node that needs to be read. It is sometimes needed to read more than one node (e. g. for fence operators). Returns the number of nodes processed or -1 if it failed.

Reimplemented from BasicElement.

Definition at line 1118 of file matrixelement.cpp.

◆ selectChild()

void MatrixElement::selectChild	(	FormulaCursor *	cursor,
		BasicElement *	child
	)

virtual

Inserts all new children at the cursor position.

Places the cursor according to the direction. Removes all selected children and returns them. Places the cursor to where the children have been. Moves the cursor to a normal place where new elements might be inserted. Sets the cursor to select the child. The mark is placed before, the position behind it.

Reimplemented from BasicElement.

Definition at line 718 of file matrixelement.cpp.

◆ toLatex()

TQString MatrixElement::toLatex ( )

virtual

Moves the cursor away from the given child.

The cursor is guaranteed to be inside this element. Returns wether the element has no more useful children (except its main child) and should therefore be replaced by its main child's content.

Returns: the latex representation of the element and of the element's children

Reimplemented from BasicElement.

Definition at line 1208 of file matrixelement.cpp.

◆ writeDom()

void MatrixElement::writeDom ( TQDomElement element )

protectedvirtual

Appends our attributes to the dom element.

		TQDomElement &	element,
		bool	oasisFormat
	)		const

protectedvirtual

Reimplemented from BasicElement.
