<p id="classSummary">
Use the <code>chrome.devtools.panels</code> module to integrate
your extension into Developer Tools window UI: create your own panels, access
existing panels, and add sidebars.
</p><p>
See <a href="devtools.html">DevTools APIs summary</a> for
general introduction to using Developer Tools APIs.
</p>
<a name="H2-0"></a><h2>Overview</h2>
<p>
Each extension panel and sidebar is displayed as a separate HTML page. All
extension pages displayed in the Developer Tools window have access to all
modules in <code>chrome.devtools</code> API, as well as to
<a href="extension.html">chrome.extension</a> API. Other extension APIs are not
available to the pages within Developer Tools window, but you may invoke them
by sending a request to the background page of your extension, similarly to how
it's done in the <a href="overview.html#contentScripts">content scripts</a>.
</p><p>
You can use the <code><a href="#method-setOpenResourceHandler">setOpenResourceHandler()</a></code> method to install a
callback function that handles user requests to open a resource (typically,
a click on a resource link in the Developer Tools window). At most one of the
installed handlers gets called; users can specify (using the Developer Tools
Settings dialog) either the default behavior or an extension to handle resource
open requests. If an extension calls <code>setOpenResourceHandler()</code>
multiple times, only the last handler is retained.
</p>
<h2 id="overview-examples">Examples</h2>
<p>The following code adds a panel contained in <code>Panel.html</code>,
represented by <code>FontPicker.png</code> on the Developer Tools toolbar
and labeled as <em>Font Picker</em>:</p>
<pre>chrome.devtools.panels.create("Font Picker",
"FontPicker.png",
"Panel.html"
function(panel) { ... });
</pre>
<p>The following code adds a sidebar pane contained in
<code>Sidebar.html</code> and titled <em>Font Properties</em> to the Elements
panel, then sets its height to <code>8ex</code>:
</p><pre>chrome.devtools.panels.elements.createSidebarPane("Font Properties",
function(sidebar) {
sidebar.setPage("Sidebar.html");
sidebar.setHeight("8ex");
});
</pre>
<p>
This screenshot demonstrates the effect the above examples would have on
Developer Tools window:

You can find examples that use this API in
<a href="samples.html#Chrome Query">Samples</a>.
