** Description changed: - Openjdk-7 and openjdk-8 do not enable native look and feel by default. But they support it. Apps use ugly blue theme, even if the code contains "UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());" - I've tried Xubuntu 14.04, Ubuntu Mate 16.04 - apps look ugly. (for example logisim) + The default System LAF - ie. UIManager.getSystemLookAndFeelClassName() - + on Linux is set to GTK for gnome desktop - ie. sun.desktop returns gnome + - and to Metal for non-gnome desktops. - To get native LAF you need to use these arguments: _JAVA_OPTIONS - -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel -Dswing.crossplatformlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel + This prevents the majority of Java applications to use the native GTK + LAF when running. + + Also, UIManager.getSystemLookAndFeelClassName() ignores the default LAF + set by the user through swing.defaultlaf (either as a system property or + in swing.properties), relying instead on it's own simplified OS/Desktop + based heuristics and defaulting to the Cross Platform LAF when those + heuristics fail. + + While the Default LAF can be set either as a system property or in + swing.properties, the System LAF can only be set as as system property, + thus there is no way to assign it system-wide. + + Historically the GTK LAF was a source of bugs and errors. It is unclear + if the situation has improved at all in the past few years. + + = Workaround = + + Currently there are only 2 alternatives to set GTK LAF system wide, both + rely on editing the swing.properties file, depending on whether the Java + application calls + UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()): + + 1) For applications that *don't* use it then add + swing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel to + swing.properties + + 2) For applications that use it then add + swing.installedlafs=com.sun.java.swing.plaf.gtk.GTKLookAndFeel to + swing.properties
