I am writing a widget to display prime numbers.
How can i output the list of say first 1000 primes in Qt ?
ex code


for(prime=1;prime<1000;++primes)
cout<<primes<<endln

Depends on what you want. You can put them in a QLabel or in a QStringListModel that is read by QListView.

Readout should look like
1
3
5
7
11
.
.
.
.
997

Qlabel doesn't allow for scroll as far as I looked at the functions.
QStringListModel probablly then .
Maybe if the list primes is read into an array or something.

Is this what you want?


QList<QString> primes;
primes << 1 << 2 << 3 << 5 << 7;

for (int i = 0; i < primes.size(); ++i) cout << primes.at(i) << endl;



if your programme is running from the command line, the output will probably be to the screen.
Under QT the output is likely to appear in the debug area.
