XBrowser

Posted by Armond on February 27, 2001 at 12:29 AM

Hi,

Just wanted to mention that you find a fully java-based web browser at :
http://www.geocities.com/xa_arnold/XBrowser.html

It's rendering engine is now based on JEditorPane but can be expanded in future to be plugged other powerful engines :)

Some screen shots are also provided there (althought a little bit old they are).
Please send me your suggestions/ideas about it!

Best Regards,
Armond

> > > Hi

You can also pass command line parameter which is a HTML file to display in the beginning. You can also enter an internet address and it will open the webpage in the frame. I have attached the short description of the program and the code.
