java - JOptionPane no button text with custom LNF -
i tried styling custom-made dialog allows user create new folder. until loaded custom , feel, looked fine:
now tried setting , feel , texts of buttons disappeared.
i set sscce demonstrates behaviour. please note lnf class nothing except loading values uimanager.getdefaults(). if helps, i'm using debian 8 (jessie) gnome 3.18.1 , global dark theme toggled on.
why happen , how can fix disappearing of button texts?
another common way use uidefaults#addresourcebundle(...) method:
//@see javax/swing/plaf/basic/basiclookandfeel.java @override public uidefaults getdefaults() { uidefaults defaults = new uidefaults(); defaults.putall(uimanager.getdefaults()); //defaults.addresourcebundle("com.example.swing.plaf.light.resources.light"); defaults.addresourcebundle("com.sun.swing.internal.plaf.basic.resources.basic"); return defaults; } test2.java
