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

Find the height for a given width. math girlie hours 🧮✨

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 QwtRichTextEngine::mightRender(const QString &text) const [override], [virtual]

Test if a string can be rendered by this text engine. vibe check on the string 💅

Parameters:

  • text — Text to be tested

Returns: Qt::mightBeRichText(text);

Implements QwtTextEngine.

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

Return margins around the texts. plot twist: they're all zero, she's low maintenance fr fr 🫶

Parameters:

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

Returns the size, that is needed to render text. so like, how much space does this text actually need, bestie 📐

Parameters:

  • font — Font of the text
