SMIL stands for Synchronized Multimedia Integration Language.SMIL allows integrating a set of independent multimedia objects into a synchronized multimedia presentation. Using SMIL, an author can

  1. describe the temporal behavior of the presentation
  2. describe the layout of the presentation on a screen
  3. associate hyperlinks with media objects

SAMPLE CODE

The code snippet to create a SMIL presentation when creating a MMS message is below:

TBool CMMSExampleContainer::CreateNewMessageL()
	{
CMsvEntry* entry = CMsvEntry::NewL(*iSession, KMsvGlobalOutBoxIndexEntryId,
TMsvSelectionOrdering());
CleanupStack::PushL(entry);
 
// Set context to the parent folder (Outbox)
iMmsMtm->SwitchCurrentEntryL( entry->EntryId() );
 
// Create new message in the Outbox and set it as the current context.
#ifdef __SERIES60_3X__ //3rd edition onwards
iMmsMtm->CreateMessageL( iMmsMtm->DefaultServiceL()  );
#else//1st and 2nd edition
iMmsMtm->CreateMessageL( iMmsMtm->DefaultSettingsL() );
#endif
CleanupStack::PopAndDestroy(); // entry
 
// Setting recipients
// use this to add the "To" recipients.
