KCOREADDONS_EXPORT void	setMessageHandler (KMessageHandler *handler)

Detailed Description

Display an informative message using a KMessageHandler.

This class does not define how to display a message, it is just a clean interface for developers to use. The job is done by the current KMessageHandler set in the class.

If no KMessageHandler is currently registered in KMessage, the message will be outputed to stderr.

Use KMessage::setMessageHandler() to use a KMessageHandler.

KMessage::setMessageHandler( new KMessageBoxHandler(this) );
// some operation
 
KMessage::message( KMessage::Error, i18n("Could not load service. Use kbuildsycoca to fix the service database."), i18n("KService") );

Some KMessageHandler are already done such as KMessageBoxMessageHandler and KPassivePopupMessageHandler.
