QTextLine::textStart() function
Message 1 in thread
Hi,
have anybody in list ever used a QTextLine::textStart() function? After
day of debugging, I still do not know what is the number that it returns
good for. At least it is not what is written in documentation:
"Returns the start of the line from the beginning of the string passed to
the QTextLayout."
I need this function a lot and I'm afraid that function or documentationit
is still buggy.

I didn't use this stuff yet, but as far as I understand the
documentation it should return the number of characters between the
start of the line and the start of the string that was set on the
QTextLayout.
It would help if you could provide a small test application that
reproduces the problems you see.

Hi,
I've found, that problem results from '\n' line breaks in text,
QTextLayout withouth textOption() set, ignores them but
painter->drawText(bounding_rect, 0, text) not. I thing that setting the
right options can solve problem, which is not in textStart() function.
Thank you and sorry for noise.
