◆ 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()

virtual void RootElement::dispatchFontCommand ( FontCommand * cmd )

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. */ virtual void draw( TQPainter& painter, const LuPixelRect& r, const ContextStyle& cstyle, ContextStyle::TextStyle tstyle, ContextStyle::IndexStyle istyle, StyleAttributes& style, const LuPixelPoint& parentOrigin );

/** Dispatch this FontCommand to all our TextElement children.

Reimplemented from BasicElement.

◆ 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.

		bool &	handled,
		const LuPixelPoint &	point,
		const LuPixelPoint &	parentOrigin )

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.
