I need to embed a very simple browser ( can parse HTML, and JS Ext ) in a Gtk Widget hopefully in gtkmm. I looked into gtkmozembed, but the c++ wrapper is very out dated, so I tried to just write it in C, but I’m already committed to Gtk+ 3.0, and gtkmozembed doesn’t work with Gtk+ 3.0. Is there a way to just extend Gtk::Widget and put a gecko parser in it? Can’t really find any gecko documentation, I keep getting redirected to gtkmozembed.
Any ideas/suggestions would be greatly appreciated.
Edit:
@Mark After I tried using Webkitgtk, I get the following output and the application crashes.

Just thought I’d come back and let anyone who cares know that our solution was to use Gtkmozembed. Only problem with it is that Gtkmozembed only runs using gtk+ 2 and I’m using gtk+ 3. The two can not exist in the same process, and I’m not migrating either project. So I’m running gtkmozembed in a child process that I use pipes to communicate with, and a GtkPlug that renders the widget in my project.
This solution is a little hokey, but it gets the job done, and the browser is embedded.
