| MCoeMessageObserver() | |
Interface for handling incoming window server messages.
This interface is used to enable FEPs to keep their settings synchronised across all running instances.
Anything that needs to be notified of messages that get sent by the window server's message-sending service should derive from this class and override its pure virtual function.
In addition, derived classes also need to call CCoeEnv::AddMessageObserverL() during construction and CCoeEnv::RemoveMessageObserver() in their destructors.
Message response flags.
| Enumerator | Value | Description |
|---|---|---|
| EMessageNotHandled |
Message not handled. | |
| EMessageHandled |
Message handled. |

Handles window server messages.
Implementations should return EMessageHandled if they are able to handle the message, or EMessageNotHandled if the message is not appropriate to this observer.
| Parameters | |
|---|---|
| aClientHandleOfTargetWindowGroup | The window group that the message was sent to. Many implementations will not need this information. |
| aMessageUid | The message UID. |
| aMessageParameters | The message parameters. |
