how to do this ?

[Petr_Kropotkin]

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

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

To copy to clipboard, switch view to plain text mode

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;

QList<QString> primes;
 primes << 1 << 2 << 3 << 5 << 7;
 
for (int i = 0; i < primes.size(); ++i) cout << primes.at(i) << endl;

To copy to clipboard, switch view to plain text mode 

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.
