QwtMathMLTextEngine - Text Engine for the MathML renderer of the Qt solutions package. SYNOPSIS
#include <qwt_mathml_text_engine.h> Inherits QwtTextEngine. Public Member Functions virtual void draw (QPainter *painter, const QRect &rect, int flags, const QString &text) const virtual int heightForWidth (const QFont &font, int flags, const QString &text, int width) const virtual bool mightRender (const QString &) const QwtMathMLTextEngine () virtual void textMargins (const QFont &, const QString &, int &left, int &right, int &top, int &bottom) const virtual QSize textSize (const QFont &font, int flags, const QString &text) const virtual ~QwtMathMLTextEngine () Detailed Description Text Engine for the MathML renderer of the Qt solutions package. The Qt Solution package includes a renderer for MathML http://www.trolltech.com/products/qt/addon/solutions/catalog/4/Widgets/qtmmlwidget that is available for owners of a commercial Qt license. You need a version >= 2.1, that is only available for Qt4. To enable MathML support the following code needs to be added to the application: #include <qwt_mathml_text_engine.h> QwtText::setTextEngine(QwtText::MathMLText, new QwtMathMLTextEngine()); See also: QwtTextEngine, QwtText::setTextEngine Warning: Unfortunately the MathML renderer doesn't support rotating of texts.

QCanvasText - Text object on a QCanvas SYNOPSIS
#include <qcanvas.h> Inherits QCanvasItem. Public Members QCanvasText ( QCanvas * canvas ) QCanvasText ( const QString & t, QCanvas * canvas ) QCanvasText ( const QString & t, QFont f, QCanvas * canvas ) virtual ~QCanvasText () void setText ( const QString & t ) void setFont ( const QFont & f ) void setColor ( const QColor & c ) QString text () const QFont font () const QColor color () const int textFlags () const void setTextFlags ( int f ) virtual QRect boundingRect () const virtual int rtti () const Protected Members virtual void draw ( QPainter & painter ) DESCRIPTION
The QCanvasText class provides a text object on a QCanvas. A canvas text item has text with font, color and alignment attributes. The text and font can be set in the constructor or set or changed later with setText() and setFont(). The color is set with setColor() and the alignment with setTextFlags(). The text item's bounding rectangle is retrieved with boundingRect(). The text can be drawn on a painter with draw(). Like any other canvas item text items can be moved with QCanvasItem::move() and QCanvasItem::moveBy(), or by setting coordinates with QCanvasItem::setX(), QCanvasItem::setY() and QCanvasItem::setZ(). See also Graphics Classes and Image Processing Classes. MEMBER FUNCTION DOCUMENTATION
QCanvasText::QCanvasText ( QCanvas * canvas ) Constructs a QCanvasText with the text "<text>", on canvas. QCanvasText::QCanvasText ( const QString & t, QCanvas * canvas ) Constructs a QCanvasText with the text t, on canvas canvas. QCanvasText::QCanvasText ( const QString & t, QFont f, QCanvas * canvas ) Constructs a QCanvasText with the text t and font f, on the canvas canvas. QCanvasText::~QCanvasText () [virtual] Destroys the canvas text item. QRect QCanvasText::boundingRect () const [virtual] Returns the bounding rectangle of the text. Reimplemented from QCanvasItem. QColor QCanvasText::color () const Returns the color of the text. See also setColor(). void QCanvasText::draw ( QPainter & painter ) [virtual protected] Draws the text using the painter painter. Reimplemented from QCanvasItem. QFont QCanvasText::font () const Returns the font in which the text is drawn. See also setFont(). int QCanvasText::rtti () const [virtual] Returns 3 (QCanvasItem::Rtti_Text). See also QCanvasItem::rtti(). Reimplemented from QCanvasItem. void QCanvasText::setColor ( const QColor & c ) Sets the color of the text to the color c. See also color() and setFont(). Example: chart/chartform_canvas.cpp. void QCanvasText::setFont ( const QFont & f ) Sets the font in which the text is drawn to font f. See also font(). void QCanvasText::setText ( const QString & t ) Sets the text item's text to t. The text may contain newlines. See also text(), setFont(), setColor(), and setTextFlags(). Example: canvas/canvas.cpp. void QCanvasText::setTextFlags ( int f ) Sets the alignment flags to f. These are a bitwise OR of the flags available to QPainter::drawText() -- see Qt::AlignmentFlags. See also setFont() and setColor(). QString QCanvasText::text () const Returns the text item's text. See also setText(). int QCanvasText::textFlags () const Returns the currently set alignment flags. See also setTextFlags() and Qt::AlignmentFlags. SEE ALSO
