Status: UNCONFIRMED

(Toolkit :: Preferences, defect)

[Mime Čuvalo]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050531 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050531 Firefox/1.0+

Basically what the title says:
I am dynamically generating listitems for a listbox and I found that if my
prefwindow was of type "prefwindow" the listbox would fail to generate a
vertical scrollbar if there were more items than rows visible.
However, if the type was set to "child" the listbox would generate fine.

Example (this code will show the bug; to correct it change the type attribute on
the prefwindow element to 'child')
<prefwindow id="fireftpOptions"
	type="prefwindow"
	buttons="accept, cancel"
	xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"
	onload="buildListbox()"
	title="Preferences">


	<script><![CDATA[
		function buildListbox() {
			var listbox = document.getElementById('test');
			for (var x = 0; x < 10; ++x) {
				listbox.appendItem(x,x);
			}
		}
	]]></script>
	<prefpane id="myPane">
		<preferences>
		</preferences>
		<listbox id="test" rows="5"/>
	</prefpane>
</prefwindow>
