Hi all,
I don't understand if this is the normal behavior/pattern, but if I want to update the configuration of an application I have first to remove/delete the configuration group (or each entry) and then write it again. That is, my application on exit does the following:

Code: Select all

 slaveConfigPtr->deleteGroup( "version" );
  KConfigGroup cgVersion = slaveConfigPtr->group( "version" );
  cgVersion.writeEntry( ... );
 


being slaveConfigPtr a KSharedConfig::Ptr type obtained from a kioslave instance as follows:

Code: Select all

KComponentData instance( "kio_rolefs" );  // in kdemain
slaveConfigPtr = slaveInstance.config();


Is this correct or is there a smarter way to "update" a section of the configuration file?

Usually KDE applications update their configuration file as changes are made - or when the Apply button is pressed. All existing values are left untouched.
