|KConfigBase *||config ()|
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.
You pass a pointer to the KConfigBase-derived object you want to work with and a string indicating the _new_ group.
