DoubleLineEdit Class Reference

Description

LineEdit to edit values in a scientific notation, operating on a DoubleDescriptor.

In the future it can be enhanced to support units. At the moment, no DoubleDescriptor with units is used with a DoubleLineEdit, therefore the handling of units is not implemented yet. Only the naming is prepared already (also to have a naming alike to DoubleSpinBox).
