Add remove_object to Proxy

[deuterium33]

It would be nice to have a proxy.remove_object() like proxy.reset_all(), but to delete the current selected object only, using the existing panel.remove_object() function.

New Feature: proxy.remove_object()

Thanks for the feedback!

Here is a description of what's been done to answer your request.
Please do not hesitate to ask if you need any other method exposed at the proxy level.

Overview

Added remove_object() method to DataLab proxy interface (local and remote) to programmatically remove the currently selected object from the active panel.

API

def remove_object(self, force: bool = False) -> None:
    """Remove current object from current panel.

    Args:
        force: if True, remove without confirmation. Defaults to False.
    """

Parameters:

• force (bool): Set to True to skip confirmation dialog (useful for scripts)

Usage Example

import numpy as np
from datalab.control.proxy import proxy_context

with proxy_context("local") as proxy:
    x = np.linspace(0, 10, 100)
    proxy.add_signal("Signal 1", x, np.sin(x))
    proxy.add_signal("Signal 2", x, np.cos(x))
    proxy.add_signal("Signal 3", x, np.sin(2*x))

    # Remove signal 2
    proxy.select_objects([2])
    proxy.remove_object(force=True)

    print(proxy.get_object_titles())  # ['Signal 1', 'Signal 2', 'Signal 3']

Implementation

Modified files following the standard proxy pattern:

• datalab/control/baseproxy.py - Abstract and base implementations
• datalab/gui/main.py - Main window method with @remote_controlled
• datalab/control/remote.py - Remote server signal and method

Testing

The method is tested in:

• datalab/tests/backbone/main_app_test.py - Local proxy test
• datalab/tests/features/common/misc_app_test.py - Main window test
• datalab/tests/features/control/embedded1_unit_test.py - Embedded mode test
• test_remove_object_feature.py - Standalone demonstration script

Excellent! Thank you very much for the quick implementation.

It works like a charm! Thanks again.
However, I noticed that "dl.remove_object()" in the Console crashes DataLab. Is that the case for you?
