Member Function Documentation

bool MultilineElement::accept ElementVisitor visitor  )  [virtual]
 

Visit this element.

An implementation of the visitor pattern.

Implements BasicElement.

Definition at line 1286 of file matrixelement.cc.

void MultilineElement::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 1510 of file matrixelement.cc.

void MultilineElement::dispatchFontCommand FontCommand cmd  )  [virtual]
 

Dispatch this FontCommand to all our TextElement children.

Reimplemented from BasicElement.

Definition at line 1603 of file matrixelement.cc.

void MultilineElement::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 1569 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 1292 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 1674 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 371 of file matrixelement.h.

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 1322 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 1301 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 1612 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 1451 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 1327 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 1360 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 1389 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 1647 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 1728 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.

Definition at line 1756 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 1630 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 1679 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 1778 of file matrixelement.cc.

void MultilineElement::writeDom QDomElement  element  )  [protected, virtual]
 

Appends our attributes to the dom element.

Reimplemented from BasicElement.

Definition at line 1692 of file matrixelement.cc.

void MultilineElement::writeMathML QDomDocument &  doc,
QDomNode  parent,
bool  oasisFormat = false
[virtual]
 

Same as above, just MathML.

Reimplemented from BasicElement.

Definition at line 1706 of file matrixelement.cc.
