OFF the lights</title><prolog><metadata><keywords/></metadata></prolog><taskbody>

<context><p>The <codeph>LightOffL()</codeph> method call switch OFF the specified

target light. Multiple light targets can be specified by using bitwise-or. </p><p>The

following code snippet demonstrates how to switch OFF lights for infinite

duration for multiple targets (Lights are switched OFF with fade-out): </p><codeblock xml:space="preserve">iLight-&gt;LightOffL( CHWRMExtendedLight::EPrimaryDisplay | CHWRMExtendedLight::EPrimaryKeyboard );</codeblock><p>The following code snippet demonstrates how to switch OFF lights for the

specified duration for one target (Lights are switched OFF with fade-out): </p><codeblock xml:space="preserve">// aDuration = 5000 milliseconds

light-&gt;LightOffL( CHWRMExtendedLight::ESecondaryDisplay, 5000 );</codeblock><p>After

the duration expires, if there are no previous infinite time duration call

in this session, the light state for target is changed to whatever state was

caused by the last infinite time duration call, or default state determined

by inactivity timer.</p><p>The following code snippet demonstrates how to

switch lights OFF for the specified duration for one target (fade-out is also

controlled): </p><codeblock xml:space="preserve">// aDuration = 5000 milliseconds

// aFadeOut = EFalse means that lights turn off instantly and fade-out is not used, 

// ETrue means that lights smoothly fade-out.

light-&gt;LightOnL( CHWRMExtendedLight::ESecondaryDisplay, 5000, EFalse );</codeblock><note> All

devices do not support fade-out. In such scenarios where fade-out is not supported,

the device behaves in its default state.</note></context>
