DialogSettings settings = new DialogSettings("root"); settings.put("Boolean1",true); settings.put("Long1",100); settings.put("Array1",new String[]{"aaaa1","bbbb1","cccc1"}); DialogSettings section = new DialogSettings("sectionName"); settings.addSection(section); section.put("Int2",200); section.put("Float2",1.1); section.put("Array2",new String[]{"aaaa2","bbbb2","cccc2"}); settings.save("c:\\temp\\test\\dialog.xml");
