public class JCheckBoxextends Component

Emulation of javax.swing.JCheckBox for the NDT (Network Diagnostic Tool) plugin.

This class provides a minimal stub implementation of a checkbox component to allow the NDT tool to run in headless environments. The checkbox maintains selection state but provides no actual visual representation.

All operations except selection state tracking are no-ops, maintaining API compatibility without requiring an actual graphical display system.
