Member Function Documentation

◆ accept()

bool BracketElement::accept ( ElementVisitor *  )
virtual

Visit this element.

An implementation of the visitor pattern.

Implements BasicElement.

Definition at line 242 of file bracketelement.cpp.

◆ calcSizes()

void BracketElement::calcSizes ( const ContextStyle &  context,
ContextStyle::TextStyle  tstyle,
ContextStyle::IndexStyle  istyle,
StyleAttributes &  style 
)
virtual

Calculates our width and height and our children's parentPosition.

Implements BasicElement.

Definition at line 286 of file bracketelement.cpp.

◆ clone()

virtual BracketElement * BracketElement::clone ( )
inlinevirtual

Implements BasicElement.

Definition at line 174 of file bracketelement.h.

◆ draw()

void BracketElement::draw ( TQPainter &  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 367 of file bracketelement.cpp.

◆ entered()

void BracketElement::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 248 of file bracketelement.cpp.

◆ formulaString()

TQString BracketElement::formulaString ( )
protectedvirtual

Reimplemented from BasicElement.

Definition at line 661 of file bracketelement.cpp.

◆ getElementName()

virtual TQString BracketElement::getElementName ( ) const
inlineprotectedvirtual

Reimplemented from BasicElement.

Definition at line 239 of file bracketelement.h.

◆ getTagName()

virtual TQString BracketElement::getTagName ( ) const
inlineprotectedvirtual

Returns the tag name of this element type.

Reimplemented from BasicElement.

Definition at line 229 of file bracketelement.h.

◆ getTokenType()

virtual TokenType BracketElement::getTokenType ( ) const
inlinevirtual
Returns
the type of this element. Used for parsing a sequence.

Reimplemented from BasicElement.

Definition at line 184 of file bracketelement.h.

◆ goToPos()

BasicElement * BracketElement::goToPos ( FormulaCursor *  cursor,
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 SingleContentElement.

Definition at line 254 of file bracketelement.cpp.

◆ readAttributesFromDom()

bool BracketElement::readAttributesFromDom ( TQDomElement  element)
protectedvirtual

Reads our attributes from the element.

Returns false if it failed.

Reimplemented from BasicElement.

Definition at line 423 of file bracketelement.cpp.

◆ readAttributesFromMathMLDom()

bool BracketElement::readAttributesFromMathMLDom ( const TQDomElement &  element)
protectedvirtual

Reads our attributes from the MathML element.

Returns false if it failed.

Reimplemented from BasicElement.

Definition at line 443 of file bracketelement.cpp.

◆ readContentFromMathMLDom()

int BracketElement::readContentFromMathMLDom ( TQDomNode &  node)
protectedvirtual

Reads our content from the MathML node.

Sets the node to the next node that needs to be read. It is sometimes needed to read more than one node (e. g. for fence operators). Returns the number of nodes processed or -1 if it failed.

Sets the node to the next node that needs to be read. Returns false if it failed.

Reimplemented from SingleContentElement.

Definition at line 518 of file bracketelement.cpp.

◆ toLatex()

TQString BracketElement::toLatex ( )
protectedvirtual
Returns
the latex representation of the element and of the element's children

Reimplemented from BasicElement.

Definition at line 622 of file bracketelement.cpp.

◆ writeDom()

void BracketElement::writeDom ( TQDomElement  element)
protectedvirtual

Appends our attributes to the dom element.

Reimplemented from SingleContentElement.

Definition at line 412 of file bracketelement.cpp.

◆ writeMathMLAttributes()

void BracketElement::writeMathMLAttributes ( TQDomElement &  element) const
protectedvirtual

Reimplemented from BasicElement.

Definition at line 787 of file bracketelement.cpp.
