Inputs classes

class pymeasure.display.inputs.BooleanInput(parameter, parent=None, **kwargs)

Bases: Input, QCheckBox

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.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(parameter, parent=None, **kwargs)

Bases: Input, QSpinBox

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.

stepEnabled(self) → QAbstractSpinBox.StepEnabledFlag

class pymeasure.display.inputs.ListInput(parameter, parent=None, **kwargs)

Bases: Input, QComboBox

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(parameter, parent=None, **kwargs)

Bases: Input, QDoubleSpinBox

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.

stepEnabled(self) → QAbstractSpinBox.StepEnabledFlag

textFromValue(self, v: float) → str

validate(self, input: str | None, pos: int)

valueFromText(self, text: str | None) → float

class pymeasure.display.inputs.StringInput(parameter, parent=None, **kwargs)

Bases: Input, QLineEdit

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.
