Member Function Documentation

◆ accept()

bool RootElement::accept ( ElementVisitor * )

virtual

Visit this element.

An implementation of the visitor pattern.

Implements BasicElement.

Definition at line 123 of file rootelement.cpp.

◆ calcSizes()

void RootElement::calcSizes	(	const ContextStyle &	cstyle,
		ContextStyle::TextStyle	tstyle,
		ContextStyle::IndexStyle	istyle,
		StyleAttributes &	style
	)

virtual

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

Implements BasicElement.

Definition at line 181 of file rootelement.cpp.

◆ clone()

virtual RootElement * RootElement::clone ( )

inlinevirtual

Implements BasicElement.

Definition at line 46 of file rootelement.h.

◆ dispatchFontCommand()

void RootElement::dispatchFontCommand ( FontCommand * cmd )

virtual

Dispatch this FontCommand to all our TextElement children.

Reimplemented from BasicElement.

Definition at line 292 of file rootelement.cpp.

◆ draw()

void RootElement::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 241 of file rootelement.cpp.

◆ entered()

void RootElement::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 129 of file rootelement.cpp.

◆ formulaString()

TQString RootElement::formulaString ( )

virtual

Reimplemented from BasicElement.

Definition at line 663 of file rootelement.cpp.

◆ getIndex()

ElementIndexPtr RootElement::getIndex ( )

inline

Definition at line 170 of file rootelement.h.

◆ getMainChild()

SequenceElement * RootElement::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 481 of file rootelement.cpp.

◆ getRadiant()

SequenceElement * RootElement::getRadiant ( )

inline

Definition at line 145 of file rootelement.h.

◆ getTagName()

virtual TQString RootElement::getTagName ( ) const

inlineprotectedvirtual

Returns the tag name of this element type.

Reimplemented from BasicElement.

Definition at line 191 of file rootelement.h.

◆ goToPos()

BasicElement * RootElement::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 BasicElement.

Definition at line 140 of file rootelement.cpp.

◆ hasIndex()

bool RootElement::hasIndex ( ) const

inline

Definition at line 168 of file rootelement.h.

◆ insert()

void RootElement::insert	(	FormulaCursor *	cursor,
		TQPtrList< BasicElement > &	newChildren,
		Direction	direction
	)

virtual

Reinserts the index if it has been removed.

Reimplemented from BasicElement.

Definition at line 417 of file rootelement.cpp.

◆ moveDown()

void RootElement::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 391 of file rootelement.cpp.

◆ moveLeft()

void RootElement::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 305 of file rootelement.cpp.

◆ moveRight()

void RootElement::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 334 of file rootelement.cpp.

◆ moveToIndex()

void RootElement::moveToIndex	(	FormulaCursor *	cursor,
		Direction	direction
	)

Moves the cursor away from the given child.

The cursor is guaranteed to be inside this element.

Definition at line 510 of file rootelement.cpp.

◆ moveUp()

void RootElement::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 363 of file rootelement.cpp.

Definition at line 595 of file rootelement.cpp.

◆ readContentFromDom()

bool RootElement::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 BasicElement.

Definition at line 562 of file rootelement.cpp.

◆ readContentFromMathMLDom()

int RootElement::readContentFromMathMLDom ( TQDomNode & node )

protectedvirtual

Reads our content from the MathML node.

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

Reimplemented from BasicElement.

Definition at line 610 of file rootelement.cpp.

◆ remove()

void RootElement::remove	(	FormulaCursor *	cursor,
		TQPtrList< BasicElement > &	removedChildren,
