Constructor & Destructor Documentation
QwtMathMLDocument::QwtMathMLDocument () Constructs an empty MML document.
QwtMathMLDocument::~QwtMathMLDocument () Destroys the MML document.
Member Function Documentation
int QwtMathMLDocument::baseFontPointSize () const Returns the point size of the font used to render expressions whose scriptlevel is 0.
See also:
setBaseFontPointSize() fontName() setFontName()
void QwtMathMLDocument::clear () Clears the contents of this MML document.
QString QwtMathMLDocument::fontName (QwtMathMLDocument::MmlFonttype) const Returns the name of the font used to render the font type.

setFontName() setBaseFontPointSize() baseFontPointSize() QwtMathMLDocument::MmlFont
void QwtMathMLDocument::paint (QPainter *p, const QPoint &pos) const Renders this MML document with the painter p at position pos.
void QwtMathMLDocument::setBaseFontPointSize (intsize) Sets the point size of the font used to render expressions whose scriptlevel is 0.
See also:
baseFontPointSize() fontName() setFontName()
bool QwtMathMLDocument::setContent (QStringtext, QString *errorMsg = 0, int *errorLine = 0, int *errorColumn = 0) Sets the MathML expression to be rendered. The expression is given in the string text. If the expression is successfully parsed, this method returns true; otherwise it returns false. If an error occured errorMsg is set to a diagnostic message, while errorLine and errorColumn contain the location of the error. Any of errorMsg, errorLine and errorColumn may be 0, in which case they are not set.
text should contain MathML 2.0 presentation markup elements enclosed in a <math> element.
void QwtMathMLDocument::setFontName (QwtMathMLDocument::MmlFonttype, const QString &name) Sets the name of the font used to render the font type to name.

fontName() setBaseFontPointSize() baseFontPointSize() QwtMathMLDocument::MmlFont
QSize QwtMathMLDocument::size () const Returns the size of this MML document, as rendered, in pixels.
