Quick answer, will try to investigate more...
The one and only other time this issue made itself known was this:
ChangeLog:
05.06.2009
* Fixed: Users in some locales reported audio automation save/load
corruption. (T356)
- Changed CtrlList::read() to use QString and QLocale instead of
strtol() and strtod().
- Checked: Other places using QString::toDouble() work OK because
QString will fallback
to 'C' locale if formatting using current locale fails. (Hmm... But
is it a speed hit?)
The issue was some locales were saving controller list values like 12,3
and others 12.3 and so on.
Take a look at how I load/save the controller values in class CtrlList.
Maybe it is what you want?
I remember checking a bunch of other places to make sure they were OK,
but that was numerals, not text.
And I remember this oddity if it sheds any kind of light, don't know if
still true today:
void Song::setUndoRedoText()
{
...
s += ", .."; // Hm, the tooltip will not show three dots "..."
...
}
Tim.
