<iframe src="http://www.test.com" width="1024" height="1024" name="SELFHTML_in_a_box" scrolling="no" frameborder=0

</div>
</body>

Your onLoad event will never be called. Put your javascript code in the provided script box below the HTML box. You'll need to put the actual code for the Pos100() function in there too - unless it's some builtin function I've not come across before.

It’s all about the css / div code I’m interested in order to get an offset of an html page.

when I put the html code into a extra page (like: www.xy.com/extra-page.html) and than insert this extra-page.html in to xibo all works fine…

With out this work around it just blinks – I thought because xibo can’t really handle iframes…

Xibo doesn't handle iframes at all - Internet Explorer does.

All that happens when you embed html is we fire up an instance of Internet Explorer that is the size of the region you've drawn, and tell it never to display the scroll bars.

I'm just trying your exact code out now and get the same flicking, although the offset seems to be handled correctly.

I'll get back to you.

Don't know. It could be a IE security thing (loading iframes from a page served from the HDD)?

We'll take a look and get back to you.

OK. Putting the following code in c:\test.html:

<html>
<body>
<div id="xx" style="position:absolute; top:-50px; left:-50px;">
<iframe src="http://www.microsoft.com" width="640" height="480" name="SELFHTML_in_a_box" scrolling="no" frameborder="0" border="0">
</div>
</body>
</html>

And then loading from IE gives me a cream bar at the top warning about active content in the page.

I killed that off by ticking "Allow Active Content to run from files on My Computer" in the advanced options, however when run from inside Xibo it still seems to be refreshing every half second or so.

I'm out of ideas for now. Your work around should get things running for you today.

Dan - any ideas?

After having a look I think the short answer is that we do not currently support iframes in embedded HTML... When it gets added to the InnerHTML of the webbrowser document it is not correctly loaded.

I can see a potential way to make this work by re-engineering the way embedded HTML works... basically construct the document first and save it to a locally stored web page in the Xibo library - then navigate to that document in one hit. This would have the added benefit of making onload work.

Thoughts Alex?

OK, I have created a bug report for this... it will get implemented in 1.0.4 and will support IFRAME's
