ControlModule()	Abstract Base class common to both DAQ_Move and DAQ_Viewer control modules
ControlModuleUI(parent)	Base Class for ControlModules UIs

6.1.1. ControlModule base classes

Both DAQ_Move and DAQ_Viewer control modules share some specificities and inherit from a base class: the ControlModule

class pymodaq.control_modules.utils.ControlModule

Abstract Base class common to both DAQ_Move and DAQ_Viewer control modules

init_signal

This signal is emitted when the chosen hardware is correctly initialized

Type

Signal[bool]

command_hardware

This signal is used to communicate with the instrument plugin within a separate thread

Type

Signal[ThreadCommand]

command_tcpip

This signal is used to communicate through the TCP/IP Network

Type

Signal[ThreadCommand]

quit_signal

This signal is emitted when the user requested to stop the module

Type

Signal[]

Attributes

initialized_state

bool: Check if the module is initialized

module_type

str: Get the module type, either DAQ_Move or DAQ_viewer

title

str: get the title of the module

Methods

grab()	Programmatic entry to grab data from detectors or current value from actuator
init_hardware([do_init])	Programmatic entry to initialize/deinitialize the control module
init_hardware_ui([do_init])	Programmatic entry to simulate a click on the user interface init button
manage_ui_actions(action_name, attribute, value)	Method to manage actions for the UI (if any).
quit_fun()	Programmatic entry to quit the controle module
show_log()	Open the log file in the default text editor
stop_grab()	Programmatic entry to stop data grabbing from detectors or current value polling from actuator
update_status(txt[, log])	Display a message in the ui status bar and eventually log the message

grab()

Programmatic entry to grab data from detectors or current value from actuator

init_hardware(do_init=True)

Programmatic entry to initialize/deinitialize the control module

Parameters

do_init (bool) – if True initialize the selected hardware else deinitialize it

See also

init_hardware_ui()

init_hardware_ui(do_init=True)

Programmatic entry to simulate a click on the user interface init button

Parameters

do_init (bool) – if True initialize the selected hardware else deinitialize it

Notes

This method should be preferred to init_hardware()

manage_ui_actions(action_name: str, attribute: str, value)

Method to manage actions for the UI (if any).

Will try to apply the given value to the given attribute of the corresponding action

Parameters

• action_name (str) –

• attribute (method signature or attribute) –

• value (object) – actual type and value depend on the triggered attribute

Examples

>>>manage_ui_actions(‘quit’, ‘setEnabled’, False) # will disable the quit action (button) on the UI

quit_fun()

Programmatic entry to quit the controle module

show_log()

Open the log file in the default text editor

stop_grab()

Programmatic entry to stop data grabbing from detectors or current value polling from actuator

update_status(txt, log=True)

Display a message in the ui status bar and eventually log the message

Parameters

• txt (str) – message to display

• log (bool) – if True, log the message in the logger

property initialized_state

Check if the module is initialized

Type

bool

property module_type

Get the module type, either DAQ_Move or DAQ_viewer

Type

str

property title

get the title of the module

Type

str

The same is also true for the UI of these modules sharing a common UI base class: the ControlModuleUI

class pymodaq.control_modules.utils.ControlModuleUI(parent)

Base Class for ControlModules UIs

command_sig

This signal is emitted whenever some actions done by the user has to be applied on the main module. Possible commands are: See specific implementation

Type

Signal[Threadcommand]
