Member Function Documentation

bool EmptyElement::accept ( ElementVisitor visitor  )  [virtual]

Visit this element.

An implementation of the visitor pattern.

Implements BasicElement.

Definition at line 481 of file textelement.cc.

void EmptyElement::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 487 of file textelement.cc.

void EmptyElement::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 505 of file textelement.cc.

virtual QChar EmptyElement::getCharacter (  )  const [inline, virtual]

Returns:
the character that represents this element. Used for parsing a sequence. Here we use a dummy so an EmptyElement pretends to be a letter.

Reimplemented from BasicElement.

Definition at line 227 of file textelement.h.

virtual QString EmptyElement::getTagName (  )  const [inline, protected, virtual]

Returns:
the tag name of this element type.

Reimplemented from BasicElement.

Definition at line 260 of file textelement.h.

QString EmptyElement::toLatex (  )  [virtual]

Returns:
the latex representation of the element and of the element's children

Reimplemented from BasicElement.
