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
QString 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.

KConfigGroupSaver ( KConfigBase* config, QString group ) : _config(config), _oldgroup(config->group()) |
Constructor. You pass a pointer to the KConfig/KSimpleConfig object you want to work with and a string indicating the _new_ group.
Parameters:
config | the KConfig/KSimpleConfig object this KConfigGroupSaver works on |
group | the new group that the KConfig/KSimpleConfig object should switch to |
