Detailed Description

The main element.

A formula consists of a FormulaElement and its children. The only element that has no parent.

Definition at line 40 of file formulaelement.h.

Constructor & Destructor Documentation

◆ FormulaElement()

KFORMULA_NAMESPACE_BEGIN FormulaElement::FormulaElement ( FormulaDocument * container )

The container this FormulaElement belongs to must not be 0, except you really know what you are doing.

Definition at line 34 of file formulaelement.cpp.

Member Function Documentation

◆ buildCommand()

KCommand * FormulaElement::buildCommand	(	Container *	container,
		Request *	request )

virtual

This is called by the container to get a command depending on the current cursor position (this is how the element gets chosen) and the request.

Returns: the command that performs the requested action with the containers active cursor.

Reimplemented from SequenceElement.

Definition at line 173 of file formulaelement.cpp.

◆ calcSizes() [1/2]

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

virtual

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

Reimplemented from SequenceElement.

Definition at line 119 of file formulaelement.cpp.

◆ calcSizes() [2/2]

void FormulaElement::calcSizes ( ContextStyle & context )

Draws the whole element including its children.

Calculates the formulas sizes and positions.

The `parentOrigin' is the point this element's parent starts. We can use our parentPosition to get our own origin then. */ virtual void draw( TQPainter& painter, const LuPixelRect& r, const ContextStyle& context, ContextStyle::TextStyle tstyle, ContextStyle::IndexStyle istyle, StyleAttributes& style, const LuPixelPoint& parentOrigin );

/** Calculates the formulas sizes and positions.

Definition at line 142 of file formulaelement.cpp.

◆ changed()

void FormulaElement::changed ( )

virtual

Gets called whenever something changes and we need to recalc.

Definition at line 74 of file formulaelement.cpp.

◆ clone()

virtual FormulaElement * FormulaElement::clone ( )

inlinevirtual

Reimplemented from SequenceElement.

Definition at line 50 of file formulaelement.h.

◆ cursorHasMoved()

void FormulaElement::cursorHasMoved ( FormulaCursor * cursor )

Gets called when a request has the side effect of moving the cursor.

In the end any operation that moves the cursor should call this.

Definition at line 79 of file formulaelement.cpp.

◆ draw()

void FormulaElement::draw	(	TQPainter &	painter,
		const LuPixelRect &	r,
		ContextStyle &	context )

Draws the whole thing.

Definition at line 128 of file formulaelement.cpp.

◆ elementRemoval()

void FormulaElement::elementRemoval ( BasicElement * child )

Gets called just before the child is removed from the element tree.

Definition at line 69 of file formulaelement.cpp.

◆ emptyFormulaElement()

TQDomElement FormulaElement::emptyFormulaElement ( TQDomDocument & doc )

For copy&paste we need to create an empty XML element.

Definition at line 190 of file formulaelement.cpp.

◆ formula() [1/2]

virtual FormulaElement * FormulaElement::formula ( )

inlinevirtual

Provide fast access to the rootElement for each child.

Reimplemented from BasicElement.

Definition at line 70 of file formulaelement.h.

◆ formula() [2/2]

virtual const FormulaElement * FormulaElement::formula ( ) const

inlinevirtual

Provide fast access to the rootElement for each child.

Reimplemented from BasicElement.

Definition at line 75 of file formulaelement.h.

◆ getBaseSize()

int FormulaElement::getBaseSize ( ) const

inline

Definition at line 166 of file formulaelement.h.

◆ getSymbolTable()

const SymbolTable & FormulaElement::getSymbolTable ( ) const

Returns: our documents symbol table

Definition at line 184 of file formulaelement.cpp.

◆ getTagName()

virtual TQString FormulaElement::getTagName ( ) const

inlineprotectedvirtual

Returns the tag name of this element type.

Reimplemented from SequenceElement.

Definition at line 192 of file formulaelement.h.

◆ goToPos()

BasicElement * FormulaElement::goToPos	(	FormulaCursor *	cursor,
		const LuPixelPoint &	point )

Returns the element the point is in.

Definition at line 56 of file formulaelement.cpp.

◆ hasOwnBaseSize()

bool FormulaElement::hasOwnBaseSize ( ) const

inline

Definition at line 169 of file formulaelement.h.

◆ input()

KCommand * FormulaElement::input	(	Container *	,
		TQKeyEvent *	)

virtual

Parses the input.

It's the container which does create new elements because it owns the undo stack. But only the sequence knows what chars are allowed.

Reimplemented from SequenceElement.

Definition at line 202 of file formulaelement.cpp.

◆ insertFormula()

void FormulaElement::insertFormula ( FormulaCursor * cursor )

Definition at line 114 of file formulaelement.cpp.

◆ moveOutAbove()

void FormulaElement::moveOutAbove ( FormulaCursor * cursor )

Definition at line 99 of file formulaelement.cpp.

◆ moveOutBelow()

void FormulaElement::moveOutBelow ( FormulaCursor * cursor )

Definition at line 94 of file formulaelement.cpp.

◆ moveOutLeft()

void FormulaElement::moveOutLeft ( FormulaCursor * cursor )

Definition at line 84 of file formulaelement.cpp.

◆ moveOutRight()

void FormulaElement::moveOutRight ( FormulaCursor * cursor )

Definition at line 89 of file formulaelement.cpp.

◆ readAttributesFromDom()

bool FormulaElement::readAttributesFromDom ( TQDomElement element )

protectedvirtual

Reads our attributes from the element.

Returns false if it failed.

Reimplemented from SequenceElement.

Definition at line 238 of file formulaelement.cpp.

◆ readContentFromDom()

bool FormulaElement::readContentFromDom ( TQDomNode & node )

protectedvirtual

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 SequenceElement.

Definition at line 271 of file formulaelement.cpp.

◆ readOnly() [1/2]

virtual bool FormulaElement::readOnly ( const BasicElement * ) const

inlinevirtual

Ordinary formulas are not write protected.

Reimplemented from BasicElement.

Definition at line 60 of file formulaelement.h.

◆ readOnly() [2/2]

virtual bool FormulaElement::readOnly ( const FormulaCursor * ) const

inlinevirtual

Returns: whether its prohibited to change the sequence with this cursor.

Reimplemented from SequenceElement.

Definition at line 65 of file formulaelement.h.

◆ removeFormula()

void FormulaElement::removeFormula ( FormulaCursor * cursor )

Gets called when the formula wants to vanish.

The one who holds it should create an appropriate command and execute it.

Definition at line 109 of file formulaelement.cpp.

◆ setBaseSize()

void FormulaElement::setBaseSize ( int size )

Definition at line 40 of file formulaelement.cpp.

◆ tell()

void FormulaElement::tell ( const TQString & msg )

Tell the user something has happened.

Definition at line 104 of file formulaelement.cpp.

◆ toLatex()

TQString FormulaElement::toLatex ( )

virtual

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

◆ writeMathML()

void FormulaElement::writeMathML	(	TQDomDocument &	doc,
		TQDomNode &	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.
