Conversion of QLists and Qvectors from floats to doubles

[mobucl]

Hi, this may be a simple question but i have looked arround and havent seen a direct answer. I have two situations, the first is:

QVector<float> test // contains a series of floating point numbers

BUT how can i convert these to QVector<double> easily. I was hoping for a simple test.toDouble() but this seems to not be the case.

Second - a bit more complex? can i convert a QList<Qlist<float> > in a similiar manner Here is some code:

QList<QList<float> > out; // create the variable discussed above
 
for (int i = 0; i< 10; i++) //create 10 Qlists to hold values
{
    out << QList<float>();
}
for (int ii = 0; ii<10;ii++ // fill the Qlists with some values
 {
     out[ii] << somevalues[ii]
  }
 
QVector<double> test;
test = out[1].toDouble // trying to take all the elements in the first Qlist of floats 
                                // and ouput them to a QVector of doubles ->DOESNT WORK

QList<QList<float> > out; // create the variable discussed above

for (int i = 0; i< 10; i++) //create 10 Qlists to hold values
{
    out << QList<float>();
}
for (int ii = 0; ii<10;ii++ // fill the Qlists with some values
 {
     out[ii] << somevalues[ii]
  }

QVector<double> test;
test = out[1].toDouble // trying to take all the elements in the first Qlist of floats 
                                // and ouput them to a QVector of doubles ->DOESNT WORK

Hope this makes sense!
