P2: Important Can't change phone's (Nokia E51) text input mode to "numeric".
Input mode always remains "predictive" when QInputDialog is opened.
Below is a sample code clip. (I have also tried id->setInputMethodHints(Qt::ImhPreferNumbers) )
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
bool ok = false;
QInputDialog *id = new QInputDialog();
id->setInputMethodHints(Qt::ImhDigitsOnly);
QString t = id->getText(
this, tr("PreferNumbers"), tr("Input"),
QLineEdit::Normal, "1", &ok);
}
