1 <!DOCTYPE html><!-- This page is a placeholder for generated extensions api doc. Note:
2 1) The <head> information in this page is significant, should be uniform
3 across api docs and should be edited only with knowledge of the
4 templating mechanism.
5 3) All <body>.innerHTML is genereated as an rendering step. If viewed in a
6 browser, it will be re-generated from the template, json schema and
7 authored overview content.
8 4) The <body>.innerHTML is also generated by an offline step so that this
9 page may easily be indexed by search engines.

247 The <code>chrome.types</code> module contains type declarations for Chrome.
248 Currently this comprises only a prototype for giving other
249 modules access to manage Chrome browser settings. This prototype is used,
250 for example, for <a href="proxy.html#property-settings"><code>chrome.proxy.setti ngs</code></a>.
251 </p>
252 <h2 id="ChromeSetting">Chrome settings</h2>
253 <p>
254 The <code>ChromeSetting</code> prototype provides a common set of functions
255 (<code>get()</code>, <code>set()</code>, and <code>clear()</code>) as
256 well as an event publisher (<code>onChange</code>) for settings of the
257 Chrome browser. The <a href="proxy.html#overview-examples">proxy settings
258 examples</a> demonstrate how these functions are intended to be used.
259 </p>
260 <h3 id="ChromeSetting-lifecycle">Scope and life cycle</h3>
261 <p>
262 Chrome distinguishes between three different scopes of browser settings:
263 </p><dl>
264 <dt><code>regular</code></dt>
265 <dd>Settings set in the <code>regular</code> scope apply to regular
266 browser windows and are inherited by incognito windows if they are not
267 overwritten. These settings are stored to disk and remain in place until
268 they are cleared by the governing extension, or the governing extension is
269 disabled or uninstalled.</dd>
270 <dt><code>incognito_persistent</code></dt>
271 <dd>Settings set in the <code>incognito_persistent</code> scope apply only
272 to incognito windows. For these, they override <code>regular</code>
273 settings. These settings are stored to disk and remain in place until
274 they are cleared by the governing extension, or the governing extension is
275 disabled or uninstalled.</dd>
276 <dt><code>incognito_session_only</code></dt>
277 <dd>Settings set in the <code>incognito_session_only</code> scope apply only
278 to incognito windows. For these, they override <code>regular</code> and
279 <code>incognito_session_only</code> settings. These settings are not
280 stored to disk and are cleared when the last incognito window is closed. They
281 can only be set when at least one incognito window is open.</dd>
282 </dl>
283 <p></p>
284 <h3 id="ChromeSetting-precedence">Precedence</h3>
285 <p>
286 Chrome manages settings on different layers. The following list describes the
287 layers that may influence the effective settings, in increasing order of
288 precedence.
289 </p><ol>
290 <li>System settings provided by the operating system</li>
291 <li>Command-line parameters</li>
292 <li>Settings provided by extensions</li>
293 <li>Policies</li>
294 </ol>
295 <p></p>
296 <p>
297 As the list implies, policies might overrule any changes that you specify with
298 your extension. You can use the <code>get()</code> function to determine whether
299 your extension is capable of providing a setting or whether this setting would
300 be overridden.
301 </p>
302 <p>
303 As discussed above, Chrome allows using different settings for regular
304 windows and incognito windows. The following example illustrates the behavior.
305 Assume that no policy overrides the settings and that an extension can set
306 settings for regular windows <b>(R)</b> and settings for incognito windows
307 <b>(I)</b>.
308 </p>
309 <p>
310 </p><ul>
311 <li>If only <b>(R)</b> is set, these settings are effective for both
312 regular and incognito windows.</li>
313 <li>If only <b>(I)</b> is set, these settings are effective for only
314 incognito windows. Regular windows use the settings determined by the lower
315 layers (command-line options and system settings).</li>
316 <li>If both <b>(R)</b> and <b>(I)</b> are set, the respective settings are
317 used for regular and incognito windows.</li>
318 </ul>
319 <p></p>
320 <p>
321 If two or more extensions want to set the same setting to different values,
322 the extension installed most recently takes precedence over the other
323 extensions. If the most recently installed extension sets only <b>(I)</b>, the
324 settings of regular windows can be defined by previously installed extensions.
325 </p>
326 <p>
327 The <em>effective</em> value of a setting is the one that results from
328 considering the precedence rules. It is used by Chrome.
