🦋 Detailed Description 🦋

so this whole thing is a Text Engine for the MathML renderer of the Qt solutions package. that's the vibe. that's the job.

the Qt Solution package ships a renderer for MathML at:

http://www.trolltech.com/products/qt/addon/solutions/catalog/4/Widgets/qtmmlwidget

…and heads up bestie, that one is available for owners of a commercial Qt license. so you need a version >= 2.1, and that version is only available for Qt4. lowkey a whole situation but okay, we move 💀

to enable MathML support you gotta add this code to the application, exactly like this:

#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. not a single rotation. it simply said no. 😭

🔥 Member Function Documentation 🔥

💖 void QwtMathMLTextEngine::draw (QPainter *painter, const QRect &rect, intflags, const QString &text) const [virtual] 💖

draws the text in a clipping rectangle. putting the words in the box, basically. slay.

Parameters:

• painter — Painter
• rect — Clipping rectangle
• flags — Bitwise OR of the flags like in for QPainter::drawText
• text — Text to be rendered

Implements QwtTextEngine.

---

🧚 int QwtMathMLTextEngine::heightForWidth (const QFont &font, intflags, const QString &text, intwidth) const [virtual] 🧚

finds the height for a given width. you hand it a width, it hands you back the height, mutual exchange, very healthy relationship ✨

Parameters:

• font — Font of the text
• flags — Bitwise OR of the flags used like in QPainter::drawText
• text — Text to be rendered
• width — Width

Returns: Calculated height

Implements QwtTextEngine.

---

🌈 bool QwtMathMLTextEngine::mightRender (const QString &text) const [virtual] 🌈

tests if a string can be rendered by QwtMathMLTextEngine. a little vibe check, if you will.

Parameters:

• text — Text to be tested

Returns: true, if text begins with '<math>'.

Implements QwtTextEngine.

---

🎀 void QwtMathMLTextEngine::textMargins (const QFont &, const QString &, int &left, int &right, int &top, int &bottom) const [virtual] 🎀

returns margins around the texts. and by "returns margins" we mean it's giving zero across the board, no cap:

Parameters:

• left — Return 0
• right — Return 0
• top — Return 0
• bottom — Return 0

Implements QwtTextEngine.

---

💜 QSize QwtMathMLTextEngine::textSize (const QFont &font, intflags, const QString &text) const [virtual] 💜

returns the size that is needed to render text. the measurements, the receipts, the whole fit check 📏

Parameters:

• font — Font of the text
• flags — Bitwise OR of the flags used like in QPainter::drawText
• text — Text to be rendered

Returns: Caluclated size

Implements QwtTextEngine.
