Keywords (APIs, classes, methods, functions): Calendar Importer API

Note!
This API is not part of the public SDK. It can be found in the SDK API Plug-in.

Purpose

The Calendar Importer API provides a class that imports a vCalendar into a CCalEntry compatible with the S60 Calendar.

Header files

#include <calsession.h>
 #include <calprogresscallback.h>
 #include <calentryview.h>
 #include <calenimporter.h>
 #include <f32file.h>
 #include <S32FILE.H>
 #include <agnimportobserver.h>

Libraries

efsrv.lib 
 calinterimapi.lib 
 calenimp.lib 
 estor.lib

Code example

The CCalSession is the interface to the Calendar file. The instantiation of CCalSession will result in a connection to the Calendar Server.

void CCalendarEventsEngine::ConstructL()
    {
    iCalSession = CCalSession::NewL();
    //Open the default calendar file
    iCalSession->OpenL(iCalSession->DefaultFileNameL());
    iWaiter =new (ELeave) CActiveSchedulerWait;
    // calender importer
    iImporter=CCalenImporter::NewL(*iCalSession);  	     
    }

Virtual functions

// Called during calendar entry view creation
 void CCalendarEventsEngine::Progress(TInt aProgress)
    {    
    }
 
 // Called on completion of calendar entry view creation
 void CCalendarEventsEngine::Completed(TInt aError)
    {
    iWaiter->AsyncStop();
    }
 
 // Returns whether or not progress notification is required
 TBool CCalendarEventsEngine::NotifyProgress()
    {
    // Progress notification is required
    return ETrue;
    }

Importing calender entries from a file:

void CCalendarEventsEngine::ImportEntriesL()
    {	
    // calender entries file 
    _LIT(KFile,"C:\\CalEntriesFile.txt");
    User::LeaveIfError(iFs.Connect());
    TInt err =  iRReadStream.Open(iFs,KFile,EFileRead);
    // An array of calender entries
    RPointerArray<CCalEntry> calEntryArray;
    iImporter->ImportVCalendarL(iRReadStream,calEntryArray);
    for (TInt k=0; k<calEntryArray.Count();k++)
        {
        // get information from this entry
        CCalEntry* calEntry = calEntryArray[k];
        TPtrC description = calEntry->SummaryL();
        if(iWaiter->IsStarted())
           {
           iWaiter->AsyncStop();	
           }
        // View class for accessing calendar entries
        iCalEntryView = CCalEntryView::NewL(*iCalSession,*this);
        iWaiter->Start();
        TInt success(0);
        iCalEntryView->StoreL(calEntryArray, success); 
        delete iCalEntryView;
        }
    calEntryArray.ResetAndDestroy(); 
    iRReadStream.Close();
    iFs.Close();
    }
