Member Function Documentation
bool MatrixElement::accept | ( | ElementVisitor * | visitor | ) | [virtual] |
Visit this element.
An implementation of the visitor pattern.
Implements BasicElement.
Definition at line 318 of file matrixelement.cc.
void MatrixElement::calcSizes | ( | const ContextStyle & | context, | |
ContextStyle::TextStyle | tstyle, | |||
ContextStyle::IndexStyle | istyle | |||
) | [virtual] |
Calculates our width and height and our children's parentPosition.
Implements BasicElement.
Definition at line 424 of file matrixelement.cc.
void MatrixElement::dispatchFontCommand | ( | FontCommand * | cmd | ) | [virtual] |
Dispatch this FontCommand to all our TextElement children.
Reimplemented from BasicElement.
Definition at line 528 of file matrixelement.cc.
void MatrixElement::draw | ( | QPainter & | painter, | |
const LuPixelRect & | r, | |||
const ContextStyle & | context, | |||
ContextStyle::TextStyle | tstyle, | |||
ContextStyle::IndexStyle | istyle, | |||
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 500 of file matrixelement.cc.
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 324 of file matrixelement.cc.
SequenceElement * MatrixElement::getMainChild | ( | ) | [virtual] |
We define the Main Child of a matrix to be the first row/column.
Reimplemented from BasicElement.
Definition at line 696 of file matrixelement.cc.
virtual QString MatrixElement::getTagName | ( | ) | const [inline, protected, virtual] |
Returns the tag name of this element type.
Reimplemented from BasicElement.
Definition at line 206 of file matrixelement.h.
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 689 of file matrixelement.cc.
BasicElement * MatrixElement::goToPos | ( | FormulaCursor * | , | |
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 330 of file matrixelement.cc.
void MatrixElement::moveDown | ( | FormulaCursor * | , | |
BasicElement * | ||||
) | [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 658 of file matrixelement.cc.
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 554 of file matrixelement.cc.
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 590 of file matrixelement.cc.
void MatrixElement::moveUp | ( | FormulaCursor * | , | |
BasicElement * | ||||
) | [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 626 of file matrixelement.cc.
bool MatrixElement::readAttributesFromDom | ( | QDomElement | element | ) | [protected, virtual] |
Reads our attributes from the element.
Returns false if it failed.
Reimplemented from BasicElement.
Definition at line 759 of file matrixelement.cc.
bool MatrixElement::readContentFromDom | ( | QDomNode & | node | ) | [protected, virtual] |
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 802 of file matrixelement.cc.
void MatrixElement::selectChild | ( | FormulaCursor * | , | |
BasicElement * | ||||
) | [virtual] |
Sets the cursor to select the child.
The mark is placed before, the position behind it.
Reimplemented from BasicElement.
Definition at line 701 of file matrixelement.cc.
QString MatrixElement::toLatex | ( | ) | [virtual] |
- Returns:
- the latex representation of the element and of the element's children
Reimplemented from BasicElement.
Definition at line 831 of file matrixelement.cc.
void MatrixElement::writeDom | ( | QDomElement | element | ) | [protected, virtual] |
Appends our attributes to the dom element.
Reimplemented from BasicElement.
Definition at line 734 of file matrixelement.cc.
void MatrixElement::writeMathML | ( | QDomDocument & | doc, | |
QDomNode & | parent, | |||
bool | oasisFormat = false | |||
) | [virtual] |
Same as above, just MathML.
Reimplemented from BasicElement.
Definition at line 883 of file matrixelement.cc.
