Detailed Description

Custom event class for OpenCPN's notification system.

Adds a std::shared<void> element to wxCommandEvent.

This class extends wxCommandEvent to add support for passing shared pointer payloads between event producers and consumers. It's used by the notification/listening system to deliver messages and data between plugins and the core application.

Key features:

• Built on standard wxWidgets event system
• Supports arbitrary data payloads via shared pointers
• Thread-safe message passing
• Reference-counted memory management
