Java’s Swing GTK LaF nice and pretty on Ubuntu
In Ubuntu Java apps which use Swing’s GTK Look and Feel (LaF) do not appear as native applications.
The menus does not have borders and do not appear as app menus on the top of the screen nor provide HUD support. The fonts on buttons and dialog boxes are thinner and do not match to the native look and feel.
This how-to describes step by step how you improve the GTK LaF of Java’s Swing apps.
For Linux Mint (Cinnamon, XFCE) refer my posting Display Java’s Swing menus correctly in GTK LaF for details.
Global Menu and HUD support
For the global menu and HUD support you need to install the package “Ayatana”. This solves the border problem as a positive side-effect. Because it is not in Ubuntu’s repositories you have to get it via PPA. You have to type in the terminal:
sudo add-apt-repository ppa:danjaredg/jayatana sudo apt-get update sudo apt-get install jayatana
Once installed, log out and log back in. If you want to perform the following steps too, you just need to log out and in at the end of the whole process.
Better Font Rendering
To improve the appearance of fonts in Java apps install the package “Infinality” from the following PPA first:
sudo add-apt-repository ppa:no1wantdthisname/ppa sudo apt-get update sudo apt-get upgrade sudo apt-get install fontconfig-infinality
After install a patch for “OpenJDK” and install/reinstall Java:
sudo add-apt-repository ppa:no1wantdthisname/openjdk-fontfix sudo apt-get update
OpenJDK7 (e.g. Ubuntu 14.04 LTS):
sudo apt-get install openjdk-7-jdk
OpenJDK8 (e.g. Ubuntu 15.04 or higher):
sudo apt-get install openjdk-8-jdk
Once installed, log out and log back in at the latest.
The following screenshot shows the Java-IDE “Netbeans” after applying this how-to:
How to revert the changes
To revert the changes made above use the following commands:
sudo apt-get --purge remove jayatana libjayatana libjayatanaag libjayatana-java libjayatanaag-java
sudo apt-get purge fontconfig-infinality sudo apt-get install ppa-purge sudo ppa-purge ppa:no1wantdthisname/ppa
sudo ppa-purge ppa:no1wantdthisname/openjdk-fontfix
Finally reinstall Java (OpenJDK7 oder OpenJDK8).
sudo apt-get remove openjdk-7-jdk openjdk-7-jre openjdk-7-jre-headless sudo apt-get install openjdk-7-jre-headless openjdk-7-jre openjdk-7-jdk
sudo apt-get remove openjdk-8-jdk openjdk-8-jre openjdk-8-jre-headless sudo apt-get install openjdk-8-jre-headless openjdk-8-jre openjdk-8-jdk
Once finished, log out and log back.
- Get Unity Global Menu / HUD Support For Java Swing Applications With JAyatana
- Better Font Rendering In Linux With Infinality
- Install OpenJDK Patched With Font Fixes
Thanks a lot for this helpful post. It worked like a charm and made the fonts look native.
Thank You for Your Feedback. I am happy that my post could help.
