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.

KConfigGroupSaver ( KConfigBase* config, QString group ) : _config(config), _oldgroup(config->group())
|
Constructor. You pass a pointer to the KConfigBase-derived
object you want to work with and a string indicating the _new_
group.
Parameters:
| |
KConfigGroupSaver ( KConfigBase* config, const char *group ) : _config(config), _oldgroup(config->group())
|
KConfigGroupSaver ( KConfigBase* config, const QCString &group ) : _config(config), _oldgroup(config->group())
