Detailed Description

Helper class for easier use of KConfig/KSimpleConfig groups.

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.
