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

<context>       <p>The<codeph> LightOffL()</codeph> method call switches 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 lights

OFF for infinite duration for multiple targets. Lights are switched OFF with

fade-out.</p><codeblock xml:space="preserve">iLight-&gt;LightOffL( CHWRMLight::EPrimaryDisplay | CHWRMLight::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( CHWRMLight::ESecondaryDisplay, 5000 );</codeblock><p>After

the duration expires, if there has not been a 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 OFF lights 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( CHWRMLight::ESecondaryDisplay, 5000, EFalse );</codeblock><note> All

devices do not support fade-out. In such scenario, the device behaves in its

default state.</note></context>
