Using this model, function calls 11 are non-blocking; the web browser continues its main thread of execution 12 and gets notified of asynchronous call completion through callbacks or some 13 other mechanism.</dd> 14 <dt>focus events</dt> 15 <dd>Events that indicate whether certain parts of a web page are 16 in or out of focus.</dd> 17 <dt>input events</dt> 18 <dd>Events that occur when an input device (such as keyboard or mouse) 19 is used to interact with an module instance.</dd> 20 <dt>instance</dt> 21 <dd>A rectangle on a web page that is managed by a Native Client module (the 22 rectangle can have <code>width=0</code> and <code>height=0</code>, which means that nothing is 23 drawn on the page).</dd> 24 <dt>manifest file</dt> 25 <dd>A file containing metadata or information about accompanying files.</dd> 26 <dt>message events</dt> 27 <dd>Events used to pass data between JavaScript and the Native Client 28 module (see the <a class="reference internal" href="/native-client/devguide/coding/message-system.html"><em>Messaging System</em></a> section).</dd> 29 <dt>module</dt> 30 <dd>Depending on context, “module” may mean one of two things. First, it may be a 31 general short-term for for “Native Client module”—compiled C/C++ code 32 produced with a Native Client toolchain (for example PNaCl). See 33 <a class="reference internal" href="/native-client/overview.html#link-how-nacl-works"><em>How Native Client works</em></a> for more details. 34 Second, it may refer to a concrete implementation of the <a class="reference external" href="/native-client/pepper_stable/cpp/classpp_1_1_module">pp::Module class</a> for some Native 35 Client module.</dd> 36 <dt>progress events</dt> 37 <dd>Events generated by the Native Client runtime system during the 38 module loading process.</dd> 39 <dt>Var</dt> 40 <dd>An object in a Native Client module that corresponds to a JavaScript 41 variable.</dd> 42 <dt>view change events</dt> 43 <dd>Events that occur when a change in the browser affects the 44 module instance (such as resizing the browser window or going to 45 and from fullscreen mode).</dd> 46 <dt>web workers</dt> 47 <dd><a class="reference external" href="http://en.wikipedia.org/wiki/Web_Workers">Web workers</a> provide a 48 mechanism for running heavy-weight JavaScript code on background threads 49 so that the main web page can continue to respond to user interaction. 50 Web pages interact with web workers by using <code>postMessage()</code> to send 51 messages. The way a web page interacts with a Native Client module 52 is analogous to the way it interacts with web workers.</dd> 53 </dl> 54 </section> 55 56 {{/partials.standard_nacl_article}} 57
