OnLynxViewDestroy

OnLynxViewDestroy is a virtual lifecycle method in the LynxExtensionModule class. It is called by the Lynx framework just before the associated LynxView instance is destroyed.

This callback is always invoked on the UI thread. It is the ideal place to perform cleanup tasks, release resources, and unregister listeners that were set up during OnLynxViewCreate.

Method Signature

virtual void OnLynxViewDestroy();

Usage

You should override this method in your custom subclass of LynxExtensionModule to ensure that all resources tied to the LynxView are properly released. Failing to do so can lead to memory leaks or other unexpected behavior.

Example

#include "lynx_extension_module.h"

class MyExtensionModule : public lynx::pub::LynxExtensionModule {
private:
    MyCustomListener* _listener;

public:
    void OnLynxViewCreate(lynx_view_t* lynx_view) override {
        // Setup resources
        _listener = new MyCustomListener();
        // ... attach listener to something
    }

    void OnLynxViewDestroy() override {
        // A LynxView is about to be destroyed.
        // Clean up all view-specific resources here.
        printf("MyExtensionModule: Cleaning up resources for LynxView.\\n");

        if (_listener) {
            // ... detach listener
            delete _listener;
            _listener = nullptr;
        }
    }

    // ... other overridden methods
};
