    Default WHAT COMPONENT CAN I USE TO READ double VALUES?

    Hi everyone, I'm having trouble finding the right component to read "double" values from the keyboard. I've tried a QDoubleSpinBox but it only take a number no longer than 2 digits before the decimal point. Can I use a QLineEdit component and than find someway to convert my input into double values? And also my program is suppose to pop-up an error message in case text is entered instead of digits. PLEASE ASSIST.

    QDoubleSpinBox has properties to set up a number of digits, max and min value. See QDoubleSpinBox::maximum, QDoubleSpinBox::minimum, QDoubleSpinBox::decimals.

    please, use tags [CODE] & [/CODE].
