[mapguide-users] Implement redling with an always on top window

Fri Sep 18 09:17:02 EDT 2009

Thank you sooooooo much Kenneth Skovhede, you are a genius.
I succeeded to implement your idea and it worked perfectly.  
I sometimes wonder "why didn't I think of that ?" :))

I'm pretty sure you can't do that, as it would be really annoying and a potential security risk
if arbitrary webpages could do that.

Instead, in the outer most page, include the viewer as an iframe:
<html>
<body>
<iframe src="......ajaxviewer/?....params..." style="... location, size, etc ...."></iframe>
<iframe src="your-tool-window.html" style=".... same ..."></iframe>
</body>
</html>

You should now be able to place the second iframe on top of the first one (z-index).
There are many JS snippets that allow you to drag an iframe around,
so you can just make the iframe look like a window.

That way, you can mimic an "always-on-top" window, but it stays within the page, so the browser
does not mind.

I have found some methods but they do not help because they give constant focus only to a window and it will not be possible to select what to draw and draw it this way ( an example will be window.showModalDialog('url', 'args')).
