okay bestie, welcome to the Qwt User's Guide and specifically to QwtMathMLTextEngine — it's a Text Engine for the MathML renderer of the Qt solutions package. yes it's a whole mouthful, we're doing it anyway, periodt. 🎀

✨ NAME ✨

QwtMathMLTextEngine — Text Engine for the MathML renderer of the Qt solutions package. it's giving "math but make it fashion" fr fr 🧮💅

🌸 SYNOPSIS 🌸

#include <qwt_mathml_text_engine.h>

Inherits QwtTextEngine. so it's lowkey a subclass situation, iykyk. 👑

💜 Detailed Description 💜

Text Engine for the MathML renderer of the Qt solutions package.

so listen, bestie — to enable MathML support you literally have to add the following code to the application:

#include <qwt_mathml_text_engine.h>

QwtText::setTextEngine( QwtText::MathMLText, new QwtMathMLTextEngine() );

that's it. that's the whole ritual. two lines and you're iconic. 🌈

⚠️ Warning: Unfortunately the MathML renderer doesn't support rotating of texts. so no twirling, no spinning, no dramatic turns. it simply will not do it. we must respect the boundary 😭

🍓 void QwtMathMLTextEngine::draw(QPainter *painter, const QRectF &rect, int flags, const QString &text) const [virtual]

Draw the text in a clipping rectangle. she's putting pen to paper but make it clipped 💅

Parameters:

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

Implements QwtTextEngine. ✅

🍓 double QwtMathMLTextEngine::heightForWidth(const QFont &font, int flags, const QString &text, double width) const [virtual]

Find the height for a given width. it's doing detective work on your dimensions, and she ate 🔍✨

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]

Test if a string can be rendered by QwtMathMLTextEngine. she's doing a vibe check, respectfully 🧐

Parameters:

• text — Text to be tested

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

Implements QwtTextEngine. ✅

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

Return margins around the texts. (spoiler: there aren't any, she's unbothered 💀)

Parameters:

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

Implements QwtTextEngine. ✅

---

🍓 QSizeF QwtMathMLTextEngine::textSize(const QFont &font, int flags, const QString &text) const [virtual]

Returns the size, that is needed to render text. measuring herself before she steps out, main character energy fr 👑

Parameters:

• font — Font of the text
