close_popup(*_: tuple[str]) → None

Close the popup window

Parameters:

_ (tuple[str]) – The event arguments.

display_autofocus_progress(data) → None

Queue the latest autofocus measurements for a Tk-thread update.

display_plot(data_and_flags: tuple[numpy.ndarray, bool, bool]) → None

Display autofocus data, handling segmentation, plot mode, and redraw.

This method unpacks and normalizes incoming data, splits it into coarse and fine segments according to the current autofocus settings, renders scatter and/or line plots on the coarse axes, optionally clears previous data, marks the detected maximum(s), and schedules a non-blocking canvas redraw.

Parameters:

data_and_flags (tuple[np.ndarray, bool, bool]) – Tuple of (data, line_plot, clear_data). data contains sample rows with stage positions in column 0 and signal values in column 1. line_plot overlays a continuous red line when true, and clear_data clears the axes and draws peak indicators when true.

Raises:

ValueError – May be raised if data is empty or has fewer than two columns (propagated from internal processing or from _plot_maxima).

execute(command, *args)

This function is called when a command is passed from a child process.

Parameters:

• command (str) – command name

• args (tuple) – command arguments

handle_autofocus_complete(payload: dict) → None

Handle autofocus completion metadata for defocus calibration.

initialize()

This function is called when the controller is initialized

This function initializes GUI based on configuration setting parameter: configuration_controller set range value for entry or spinbox widgets; add values to combobox get other necessary information for configuration.yml

populate_experiment_values() → None

Populate Experiment Values

Populates the experiment values from the experiment settings dictionary

refresh_bounds_validation() → list[str]

Returns:

Immediately knowable bounds diagnostics.

Return type:

list[str]

register_event_listener(event_name, event_handler)

Register event listener in the parent_controller

Parameters:

• event_name (str) – event name

• event_handler (function) – event handler

set_acquisition_state(state: str) → None

Update the acquisition lifecycle state and popup actions.

set_autofocus_state(is_active: bool) → None

Update autofocus activity and popup actions.

set_experiment_values()

Sets values of widgets based on experiment setting

setting_dict is a dictionary

show_autofocus_setting(*_: tuple[str]) → None

Show Autofocus Parameters

Parameters:
