schrodinger.application.matsci.qualityslider module

A QSlider that allows the user to select Jaguar keywords based on Coarse/Medium/Accurate settings. The keywords are displayed to the user in a QLineEdit that by default is editable by the user. The main widget is a QFrame object that has a .slider property that is the QSlider and a .line_edit property that is the QLineEdit.

Alternatively, the Frame can contain radiobuttons instead of a QSlider
