Split QString into left/right substrings ?
Message 1 in thread
Given, say, a QString containing:
"one, two, three, four, five"
can someone suggest a straightforward method to split this
into "one" and " two, three, four, five" i.e. at the first
occurrence of the "," separator - I can't see any obvious
QString method that does this trivially.

Look into combining QString::chop() and QString::right().

Personally, I would use QtString::split and QtString::join for this.
Gives you a lot more parsing options for the particles.

Another alternative is QString::indexOf(), QString::left() and
QString::right().

Try this code:
QString str = "one, two, three, four, five";
QRegExp sep("^*,");
qDebug() << str.section(sep, 0, 0);
qDebug() << str.section(sep, 1);
