This is really, really bad.... from qt/src/gui/painting/qpainter.cpp, inside
void QPainter::drawText(const QPointF &p, const QString &str, int tf, int
justificationPadding)
I see this code:
QStackTextEngine engine(str, d->state->font);
engine.option.setTextDirection(d->state->layoutDirection);
engine.itemize();
QScriptLine line;
line.length = str.length();
engine.shapeLine(line);
int nItems = engine.layoutData->items.size();
QVarLengthArray<int> visualOrder(nItems);
QVarLengthArray<uchar> levels(nItems);
for (int i = 0; i < nItems; ++i)
levels[i] = engine.layoutData->items[i].analysis.bidiLevel;
QTextEngine::bidiReorder(nItems, levels.data(), visualOrder.data());
Now... it seems like QTextEngine::bidiReorder() does exactly what you want
logical->visual. However... this class is defined inside qtextengine_p.h...
which means this is not official API.
But, IMHO, even if it's not marked, you can open a bug report on this at
Nokia's bug tracker, and they will handle it for Qt 4.8, maybe 4.7. Meanwhile,
if the header is installed - abuse it. If it's not included - hack it inside
your application
(*) I know that this will not be accepted at KDE's svn ...
