Body
<p>I'm running into some sort of event loop issue when making real time changes to browser.xul from a Firefox extension. Changes I am making to the browser.xul are not reflected in the browser window until my code finishes. This happens even when I use setTimeout.</p> <p>I have an example that demonstrates the issue below. When I click on the "xultest runtest" button nothing happens for a few seconds and then the xultest-text is shown as XXXXXXXXXX. I never see the XX,XXX,XXXX... in between.</p> <p>Can someone explain what is going on with the browser.xul event loop and how to work around it (thanks!)?</p> <pre><code><?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet href="css/overlay.css" type="text/css"?> <overlay id="xultest-overlay" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="text/javascript"> <![CDATA[ function xultestRunTest2() { for (var i = 0; i < 10; i++) { setTimeout(function() { document.getElementById("xultest-text").value = document.getElementById("xultest-text").value + "X" }, 5000); } } ]]> </script> <toolbox id="navigator-toolbox"> <toolbar id="xultest-toolbar" toolbarname="xultesttoolbar" class="chromeclass-toolbar" context="toolbar-context-menu" hidden="false" persist="hidden"> <toolbarbutton oncommand="xultestRunTest2();" label="xultest runtest" /> <label id="xultest-text" class="toolbarbutton-text" value="X"></label> </toolbar> </toolbox> </overlay> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
