This section explains the initial set up steps to be performed to write a UI MTM. It does not explain the implementation of all UI MTM functionality.
The most
basic functionality required in a UI MTM is to open a message (for
viewing or editing) and close it again. The CBaseMtmUi::OpenL() function opens the current context; the actual behaviour is dependent
on the entry that the context points at.
The base class of
UI MTM, CBaseUiMtm, defines functions that return CMsvOperation objects for control of asynchronous operations.
Implementers of these functions are required to provide suitable classes
that are derived from CMsvOperation. For example,
if CBaseUiMtm::EditL() is implemented to provide
message editing, a derived CMsvOperation class
must be provided that completes when the editing operation is complete.
CBaseMtmUi class.
CRegisteredMtmDll parameter.
CMsvOperation -based classes for
performing the different operations that are required for your Messaging
protocol.
