navigation

The elements are responsible to handle cursor movement themselves. To do this they need to know the direction the cursor moves and the element it comes from.

The cursor might be in normal or in selection mode.

/** 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. */ void MatrixElement::moveLeft(FormulaCursor* cursor, BasicElement* from) { if (cursor->isSelectionMode()) { getParent()->moveLeft(cursor, this); } else { if (from == getParent()) { getElement(getRows()-1, getColumns()-1)->moveLeft(cursor, this); } else { bool linear = cursor->getLinearMovement(); uint row = 0; uint column = 0; if (searchElement(from, row, column)) { if (column > 0) { getElement(row, column-1)->moveLeft(cursor, this); } else if (linear && (row > 0)) { getElement(row-1, getColumns()-1)->moveLeft(cursor, this); } else { getParent()->moveLeft(cursor, this); } } else { getParent()->moveLeft(cursor, this); } } } }

/** 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. */ void MatrixElement::moveRight(FormulaCursor* cursor, BasicElement* from) { if (cursor->isSelectionMode()) { getParent()->moveRight(cursor, this); } else { if (from == getParent()) { getElement(0, 0)->moveRight(cursor, this); } else { bool linear = cursor->getLinearMovement(); uint row = 0; uint column = 0; if (searchElement(from, row, column)) { if (column < getColumns()-1) { getElement(row, column+1)->moveRight(cursor, this); } else if (linear && (row < getRows()-1)) { getElement(row+1, 0)->moveRight(cursor, this); } else { getParent()->moveRight(cursor, this); } } else { getParent()->moveRight(cursor, this); } } } }

/** Enters this element while moving up starting inside the element `from'. Searches for a cursor position inside this element or above it. */ void MatrixElement::moveUp(FormulaCursor* cursor, BasicElement* from) { if (cursor->isSelectionMode()) { getParent()->moveUp(cursor, this); } else { if (from == getParent()) { getElement(0, 0)->moveRight(cursor, this); } else { uint row = 0; uint column = 0; if (searchElement(from, row, column)) { if (row > 0) { getElement(row-1, column)->moveRight(cursor, this); } else { getParent()->moveUp(cursor, this); } } else { getParent()->moveUp(cursor, this); } } } }

/** Enters this element while moving down starting inside the element `from'. Searches for a cursor position inside this element or below it. */ void MatrixElement::moveDown(FormulaCursor* cursor, BasicElement* from) { if (cursor->isSelectionMode()) { getParent()->moveDown(cursor, this); } else { if (from == getParent()) { getElement(0, 0)->moveRight(cursor, this); } else { uint row = 0; uint column = 0; if (searchElement(from, row, column)) { if (row < getRows()-1) { getElement(row+1, column)->moveRight(cursor, this); } else { getParent()->moveDown(cursor, this); } } else { getParent()->moveDown(cursor, this); } } } }

/** 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.

◆ readAttributesFromDom()

bool MatrixElement::readAttributesFromDom ( TQDomElement element )

protectedvirtual

Reads our attributes from the element.

Returns false if it failed.

Reimplemented from BasicElement.

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.

◆ readContentFromDom()

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.

Reimplemented from BasicElement.

Definition at line 764 of file matrixelement.cpp.

◆ writeMathMLAttributes()

void MatrixElement::writeMathMLAttributes ( TQDomElement & element ) const

protectedvirtual

Reimplemented from BasicElement.

Definition at line 1259 of file matrixelement.cpp.

◆ writeMathMLContent()

void MatrixElement::writeMathMLContent	(	TQDomDocument &	doc,
		TQDomElement &	element,
		bool	oasisFormat ) const

protectedvirtual
