An Easy Answer For An Old Hand
-
This is probably the silliest question on the planet -
But when my user enters a value into a spin box - how do I make sure it comes as only an int? I need to perform math on it ... and I am so new - the help docs help a little - but very cryptic in the beginning.
So basically - What I have is below. I can pull values from the GUI no problem - but I want the value to be an integer.
void MainWindow::on_spinBox_valueChanged(const QString)
{
QString days;
days=ui->spinBox->text();
} -
