Constructor & Destructor Documentation
MultilineElement::MultilineElement | ( | BasicElement * | parent = 0 |
) |
The container this FormulaElement belongs to must not be 0, except you really know what you are doing.

Member Function Documentation
bool MultilineElement::accept | ( | ElementVisitor * | visitor | ) | [virtual] |
Visit this element.
An implementation of the visitor pattern.
Implements BasicElement.
Definition at line 2171 of file matrixelement.cc.
void MultilineElement::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 2177 of file matrixelement.cc.
BasicElement * MultilineElement::goToPos | ( | FormulaCursor * | cursor, | |
bool & | handled, | |||
const LuPixelPoint & | point, | |||
const LuPixelPoint & | parentOrigin | |||
) | [virtual] |
Returns the element the point is in.
Reimplemented from BasicElement.
Definition at line 2186 of file matrixelement.cc.
void MultilineElement::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 2207 of file matrixelement.cc.
void MultilineElement::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 2212 of file matrixelement.cc.
void MultilineElement::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 2245 of file matrixelement.cc.
void MultilineElement::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 2274 of file matrixelement.cc.
void MultilineElement::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 2336 of file matrixelement.cc.
void MultilineElement::calcSizes | ( | const ContextStyle & | style, | |
ContextStyle::TextStyle | tstyle, | |||
ContextStyle::IndexStyle | istyle, | |||
StyleAttributes & | style | |||
) | [virtual] |
Calculates our width and height and our children's parentPosition.
Implements BasicElement.
Definition at line 2395 of file matrixelement.cc.
void MultilineElement::draw | ( | QPainter & | painter, | |
const LuPixelRect & | r, | |||
const ContextStyle & | context, | |||
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 2456 of file matrixelement.cc.
void MultilineElement::dispatchFontCommand | ( | FontCommand * | cmd | ) | [virtual] |
Dispatch this FontCommand to all our TextElement children.
Reimplemented from BasicElement.
Definition at line 2491 of file matrixelement.cc.
void MultilineElement::insert | ( | FormulaCursor * | cursor, | |
QPtrList< BasicElement > & | newChildren, | |||
Direction | direction | |||
) | [virtual] |
Inserts all new children at the cursor position.
Places the cursor according to the direction.
The list will be emptied but stays the property of the caller.
Reimplemented from BasicElement.
Definition at line 2500 of file matrixelement.cc.
void MultilineElement::remove | ( | FormulaCursor * | cursor, | |
QPtrList< BasicElement > & | removedChildren, | |||
Direction | direction | |||
) | [virtual] |
Removes all selected children and returns them.
Places the cursor to where the children have been.
Reimplemented from BasicElement.
Definition at line 2518 of file matrixelement.cc.
void MultilineElement::normalize | ( | FormulaCursor * | , | |
Direction | ||||
) | [virtual] |
Moves the cursor to a normal place where new elements might be inserted.
Reimplemented from BasicElement.
Definition at line 2535 of file matrixelement.cc.
SequenceElement * MultilineElement::getMainChild | ( | ) | [virtual] |
Removes the child.
If this was the main child this element might request its own removal. The cursor is the one that caused the removal. It has to be moved to the place any user expects the cursor after that particular element has been removed.
Reimplemented from BasicElement.
Definition at line 2562 of file matrixelement.cc.
void MultilineElement::selectChild | ( | FormulaCursor * | cursor, | |
BasicElement * | child | |||
) | [virtual] |
Sets the cursor to select the child.
The mark is placed before, the position behind it.
Reimplemented from BasicElement.
Definition at line 2567 of file matrixelement.cc.
QString MultilineElement::toLatex | ( | ) | [virtual] |
- Returns:
- the latex representation of the element and of the element's children
Reimplemented from BasicElement.
Definition at line 2666 of file matrixelement.cc.
void MultilineElement::writeMathML | ( | QDomDocument & | doc, | |
QDomNode & | parent, | |||
bool | oasisFormat = false | |||
) | const [virtual] |
Same as above, just MathML.
It shouldn't be redefined but for exceptional cases, use the general writeMathML* API instead
Reimplemented from BasicElement.
Definition at line 2594 of file matrixelement.cc.
virtual QString MultilineElement::getTagName | ( | ) | const [inline, protected, virtual] |
Returns the tag name of this element type.
Reimplemented from BasicElement.
Definition at line 432 of file matrixelement.h.
void MultilineElement::writeDom | ( | QDomElement | element | ) | [protected, virtual] |
Appends our attributes to the dom element.
Reimplemented from BasicElement.
Definition at line 2580 of file matrixelement.cc.
bool MultilineElement::readAttributesFromDom | ( | QDomElement | element | ) | [protected, virtual] |
Reads our attributes from the element.
Returns false if it failed.
Reimplemented from BasicElement.
Definition at line 2616 of file matrixelement.cc.
bool MultilineElement::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.
