madgui.widget.spinbox module

Custom spin box widgets.

Classes

AbstractSpinBox(*args, **kwargs)

Base class for custom spinbox controls.

QuantitySpinBox(*args, **kwargs)

ExpressionSpinBox(*args, **kwargs)

class madgui.widget.spinbox.AbstractSpinBox(*args, **kwargs)[source]

Bases: madgui.widget.quantity.ValueControlBase, PyQt5.QtWidgets.QAbstractSpinBox

Base class for custom spinbox controls.

Subclassing QAbstractSpinBox or QDoubleSpinBox directly with PyQt is hard, because they do not expose access to several crucial APIs:

  • prefix and suffix (QAbstractSpinBox)

  • no null values,

  • can’t control round()

  • NaN is reset to maximum in bound()

  • no unit editing

  • rounding is ‘f’-based
