QInputDialog::getDouble only take int,but not double

Mikee

Hi.

bool ok;
   double d = QInputDialog::getDouble(this, tr("ParametrForStrategy"),
                                          tr("double:"), 37.56, -10000, 10000, 0.01, &ok);
   if (ok) {qDebug()<<d;}

In dialog window I can only enter int, but not double. How to fix it?

bool ok;
double d = QInputDialog::getDouble(this, tr("ParametrForStrategy"),
                                          tr("double:"), 37.56, -10000, 10000, 0.01, &ok);
if (ok) {qDebug()<<d;}

Your seventh argument is incorrect. Documentation says that decimals is the maximum number of decimal places the number may have. Corrected version:

bool ok;
double d = QInputDialog::getDouble(this, tr("ParametrForStrategy"),
                                          tr("double:"), 37.56, -10000, 10000, 2, &ok);
if (ok) {qDebug()<<d;}
