DJ Native Swing is a nice solution to embed native components (Web Browser, Flash Player, etc.).
There was still a general issue that this library did not resolve though: the possibility to mix heavyweight and lightweight components with lightweight components on top, to change their Z-order or re-parent them.
Fortunately, The release 0.9.3 offers interesting advances in this area.
Using these features is as simple as changing some options before instanciating native components, in order to extend their behavior.
You can try all the features (including the new options) with the Webstart Demo: http://djproject.sourceforge.net/ns/DJNativeSwingDemo.jnlp
The Webstart demo is configured to work on Windows. It also works on Linux (GTK, x86/i386) where XULRunner is installed. Note that this demo is part of the release package.
In my opinion, this gets us one step closer to proper native integration. What do you think? Have you got any comments or suggestions?
