Inputs classes

class pymeasure.display.inputs.BooleanInput(*args: Any, **kwargs: Any)

Bases: pyqtgraph.Qt.QtWidgets.QCheckBox, pymeasure.display.inputs.Input

Checkbox for boolean values, connected to a BooleanParameter.

set_parameter(parameter)

Connects a new parameter to the input box, and initializes the box value.

Parameters

parameter – parameter to connect.

class pymeasure.display.inputs.FloatInput(*args: Any, **kwargs: Any)

Bases: pyqtgraph.Qt.QtWidgets.QDoubleSpinBox, pymeasure.display.inputs.Input

Spin input box for floating-point values, connected to a FloatParameter.

Class ScientificInput

For inputs in scientific notation.

set_parameter(parameter)

Connects a new parameter to the input box, and initializes the box value.

Parameters

parameter – parameter to connect.

class pymeasure.display.inputs.Input(parameter, **kwargs)

Bases: object

Mix-in class that connects a Parameter object to a GUI input box.

Parameters

parameter – The parameter to connect to this input box.

Attr parameter

Read-only property to access the associated parameter.

property parameter

The connected parameter object. Read-only property; see set_parameter().

Note that reading this property will have the side-effect of updating its value from the GUI input box.

set_parameter(parameter)

Connects a new parameter to the input box, and initializes the box value.

Parameters

parameter – parameter to connect.

update_parameter()

Update the parameter value with the Input GUI element’s current value.

class pymeasure.display.inputs.IntegerInput(*args: Any, **kwargs: Any)

Bases: pyqtgraph.Qt.QtWidgets.QSpinBox, pymeasure.display.inputs.Input

Spin input box for integer values, connected to a IntegerParameter.

set_parameter(parameter)

Connects a new parameter to the input box, and initializes the box value.

Parameters

parameter – parameter to connect.

class pymeasure.display.inputs.ListInput(*args: Any, **kwargs: Any)

Bases: pyqtgraph.Qt.QtWidgets.QComboBox, pymeasure.display.inputs.Input

Dropdown for list values, connected to a ListParameter.

set_parameter(parameter)

Connects a new parameter to the input box, and initializes the box value.

Parameters

parameter – parameter to connect.

class pymeasure.display.inputs.ScientificInput(*args: Any, **kwargs: Any)

Bases: pyqtgraph.Qt.QtWidgets.QDoubleSpinBox, pymeasure.display.inputs.Input

Spinner input box for floating-point values, connected to a FloatParameter. This box will display and accept values in scientific notation when appropriate.

Class FloatInput

For a non-scientific floating-point input box.

set_parameter(parameter)

Connects a new parameter to the input box, and initializes the box value.

Parameters

parameter – parameter to connect.

class pymeasure.display.inputs.StringInput(*args: Any, **kwargs: Any)

Bases: pyqtgraph.Qt.QtWidgets.QLineEdit, pymeasure.display.inputs.Input

String input box connected to a Parameter. Parameter subclasses that are string-based may also use this input, but non-string parameters should use more specialised input classes.
