An implementation of the visitor pattern.
Implements BasicElement.
Definition at line 1286 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.

const LuPixelPoint & parentOrigin

) [virtual]

Returns the element the point is in.

Reimplemented from BasicElement.
Definition at line 1301 of file matrixelement.cc.
References BasicElement::goToPos().

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.

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.
References FormulaCursor::isSelectionMode().

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.
References FormulaCursor::getPos(), FormulaCursor::isSelectionMode(), and FormulaCursor::setTo().

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.
References FormulaCursor::getPos(), FormulaCursor::isSelectionMode(), and FormulaCursor::setTo().

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.
References ContextStyle::axisHeight(), ContextStyle::getAdjustedSize(), ContextStyle::getDefaultFont(), ContextStyle::getThinSpace(), KoTextZoomHandler::layoutUnitPtToPt(), KoTextZoomHandler::ptToLayoutUnitPt(), and KoZoomHandler::ptToPixelY().

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.

Dispatch this FontCommand to all our TextElement children.

Reimplemented from BasicElement.
Definition at line 1603 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.

References BasicElement::formula().

void MultilineElement::remove ( FormulaCursor * cursor,

QPtrList< BasicElement > & removedChildren,
