Special thanks to Yvan for inspiring me to dust off this little demo.
This was a CBE demo which I converted to use X. Its a simple implementation that utilizes xEnableDrag().
I threw this together quickly... so it's probably not perfect - but it should give you some ideas :-)
The X core is designed for Opera 5+ (*), Mozilla, Firefox, Safari, WebKit, Internet Explorer 4+, Konqueror, Netscape 4.75+ (*) and browsers with similar object models. Object-detection instead of browser-detection is used exclusively. Currently, I'm testing with the following browsers. X has been tested by others on a wide variety of platforms.
WinXP: Opera 9.20, Firefox 2.0.0.3, Safari 3.0.2 and Internet Explorer 4, 5 and 7.
Win2K: Opera 7.51, FireFox 1.5.0.7 and Internet Explorer 6.
If you are using X, XC or anything from this site, show off your work by posting a link in the X Showcase forum.
