Create an instance of CHWRMLight instance -using NewL() or NewLC() methods. After creating -the instance, lights can be directly controlled via the provided class methods.

Without -notify handling

Create an instance of the CHWRMLight implementation -class using the NewL() or NewLC() constructor -without a parameter.

The following code snippet demonstrates how to -create an instance without notify handling to control the lights of the device:

CHWRMLight* light = CHWRMLight::NewLC(); // No callbacks

With notify handling

Derive a class from the MHWRMLightObserver interface -and implement the LightStatusChanged() method.

The -following code snippet is an example of the header of the class implemented -by the client:

// INCLUDES -#include HWRMLight.h // Link against HWRMLightClient.lib. -class CLightStatusObserver : public CBase, - public MHWRMLightObserver - { - public: - CLightStatusObserver(); - ~CLightStatusObserver(); - void ConstructL(); - static CLightStatusObserver* NewL(); - //from MHWRMLightObserver - virtual void LightStatusChanged( TInt aTarget, - CHWRMLight::TLightStatus aStatus ); - private: - CHWRMLight* iLight; - };

Create an instance of the CHWRMLight implementation -class using the NewL() or NewLC() constructor -with a parameter. This parameter is a pointer to an object that is derived -from MHWRMLightObserver. After this, lights can be directly -controlled through the provided class methods. Every light status change causes -a notification using MHWRMLightObserver::LightStatusChanged().
