KDE Look and Feel for Java Preview

Filed under

Sekou Diakite has released an alpha version of a KDE Look and Feel for Java. This is an interesting step forward in Linux/Unix desktop integration since Java applications can now use the KDE/Qt libraries for drawing Java widgets and even directly use existing KDE widgets such as the file or color choosers. See the webpage for further details of this accomplishment including future plans and, of course, screenshots.

How this is done ?

  • A KDE application is created offscreen and never showed.
  • Everytime swing needs to draw a widget :
    • The equivalent widget is drawn to a QPixmap via the offscreen KDE application (The drawing is done by QStyle methods),
    • The QPixmap is converted to a Java BufferedImage,
    • Swing draws this image as the widget background.

Radeon vs. Nouveau Open-Source Drivers On Mesa Git + Linux 4.9

For your viewing pleasure this Friday are some open-source AMD vs. NVIDIA numbers when using the latest open-source code on each side. Linux 4.9-rc1 was used while Ubuntu 16.10 paired with the Padoka PPA led to Mesa Git as of earlier this week plus LLVM 4.0 SVN. As covered recently, there are no Nouveau driver changes for Linux 4.9 while we had hoped the boost patches would land. Thus the re-clocking is still quite poor for this open-source NVIDIA driver stack. For the Nouveau tests I manually re-clocked each graphics card to the highest performance state (0f) after first re-clocking the cards to the 0a performance state for helping some of the GPUs that otherwise fail with memory re-clocking at 0f, as Nouveau developers have expressed this is the preferred approach for testing.

Ubuntu MATE, Not Just a Whim

I've stated for years how much I dislike Ubuntu's Unity interface. Yes, it's become more polished through the years, but it's just not an interface that thinks the same way I do. That's likely because I'm old and inflexible, but nevertheless, I've done everything I could to avoid using Unity, which usually means switching to Xubuntu. I actually really like Xubuntu, and the Xfce interface is close enough to the GNOME 2 look, that I hardly miss the way my laptop used to look before Unity. I wasn't alone in my disdain for Ubuntu's flagship desktop manager switch, and many folks either switched to Xubuntu or moved to another Debian/Ubuntu-based distro like Linux Mint. The MATE desktop started as a hack, in fact, because GNOME 3 and Unity were such drastic changes. I never really got into MATE, however, because I thought it was going to be nothing more than a hack and eventually would be unusable due to old GNOME 2 libraries phasing out and so forth. Read more
