Work around issues with Qt5 and Arabic text
Thanks Richard, I'll have a look. Guillaume, any intuition why master is
different from stable in this respect?
I can confirm that using QFontMetrics::width instead of the width
returned by QTextLayout does the trick, but that makes me a bit nervous :)
What happens basically is that \not has 0 width, but QTextLayout does
not seem to respect that. Several workarounds exist
- have a different FontMetrics::width for maths
- in mathed_string_dim, use width(char_type) repeatedly instead of
width(docstring)
- or do a shortcut for cases where the string only has one character.
All these things would work, but they are fragile as long as we do not know:
- why they work
- why is master immune to the problem
Guillaume, could it just be that the definition of \not needs to be
adjusted like it has been in master?
JMarc
