java.lang.Objectorg.kde.koala.KConfigGroupSaver
public class KConfigGroupSaver
Helper class to facilitate working with KConfig / KSimpleConfig groups. Careful programmers always set the group of a KConfig KSimpleConfig object to the group they want to read from and set it back to the old one of afterwards. This is usually written as:
String oldgroup config.group(); config.setGroup( "TheGroupThatIWant" ); ... config.writeEntry( "Blah", "Blubb" ); config.setGroup( oldgroup );In order to facilitate this task, you can use KConfigGroupSaver. Simply construct such an object ON THE STACK when you want to switch to a new group. Then, when the object goes out of scope, the group will automatically be restored. If you want to use several different groups within a function or method, you can still use KConfigGroupSaver: Simply enclose all work with one group (including the creation of the KConfigGroupSaver object) in one block. KConfigGroup provides similar functionality in a more object oriented way.
