class KConfigGroupSaver

Public Methods

•  KConfigGroupSaver ( KConfigBase* config, QString group )
•  KConfigGroupSaver ( KConfigBase* config, const char *group )
•  KConfigGroupSaver ( KConfigBase* config, const QCString &group )
•  ~KConfigGroupSaver ()
• KConfigBase*  config ()

Detailed Description

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.

See also: KConfigBase, KConfig, KSimpleConfig

Constructor. You pass a pointer to the KConfigBase-derived object you want to work with and a string indicating the _new_ group.

Parameters:

config	The KConfigBase-derived object this KConfigGroupSaver works on.
group	The new group that the config object should switch to.
