Qt + Calendar Interim API

[chriske86]

Hi!

I need to use CalInterim API in my Qt project, because the Mobility API doesn't contains yet the Calendar API. I just need to add Notifys for some days, and remove them. Is there anybody who did this before? Could someone give an example code, how can I use this Symbian API from Qt?

Thank you very much!

Qt is library plateform , not the OS of the mobile thats why we are telling Qt for Symbian , or Qt for Meamo.

You can not run the symbian API or symbian code in Qt library.
You have to wait for the calendar API in the next Qt mobility version, because you can not use symbian native API.

Thanks for the answer, but I'm using a native Symbian API in Qt, to lock the device orientation... and it's working fine...

Some API will work But I dont think calendar API work. Because in Qt mobility API also does not have calendar API,

The camera API and calendar API are going to be included in the next release.

I think you should use CalInterim API to get events' ids or description, convert them to Qt string for displaying. There is calendar example and example for using s60 native API with Qt signals and slots. I'll look for them. Creating events shouldn't be a problem, too. I don't see any reason for CalInterim to not to work when used with Qt ui.

I assume you know a bit of Symbian . Examples could be found on Nokia's web pages.


#include <e32base.h>
#include <calsession.h>
#include <calprogresscallback.h>
#include <calentryview.h>
#include <caliterator.h>

class MCalendarObserver
{
virtual void newEntryFound(CCalEntry* calEntry) =0;
};

class CCalendarEngine: public MCalProgressCallBack
{
public:
static CCalendarEngine* NewL(MCalendarObserver& iObserver);
CCalendarEngine(MCalendarObserver& aObserver);
virtual ~CCalendarEngine();

void SearchCalendar();

// Overridden functions of MCalProgressCallBack class
void Progress(TInt aPercentageCompleted);
void Completed(TInt aError);
TBool NotifyProgress();

private:
void ConstructL();

public:
CCalSession* iCalSession;
CCalEntryView* iCalEntryView;
CActiveSchedulerWait* iWaiter;

private:
MCalendarObserver& iObserver;

};

---------------------------------

#include "CalendarEngine.h"

CCalendarEngine* CCalendarEngine::NewL(MCalendarObserver& iObserver)
{
CCalendarEngine* self = new (ELeave) CCalendarEngine(iObserver);
CleanupStack::PushL(self);
self->ConstructL();
CleanupStack::Pop();
return self;
}

CCalendarEngine::CCalendarEngine(MCalendarObserver& aObserver):iObserver(aObserver)
{
}

void CCalendarEngine::ConstructL()
{
iCalSession = CCalSession::NewL();
iCalSession->OpenL(iCalSession->DefaultFileNameL());
iWaiter = new (ELeave) CActiveSchedulerWait;
}

CCalendarEngine::~CCalendarEngine()
{
if (iCalSession) {
delete iCalSession;
iCalSession = NULL;
}
if (iWaiter) {
delete iWaiter;
}
}

// Called during calendar entry view creation
void CCalendarEngine::Progress(TInt aProgress)
{
}

// Called on completion of calendar entry view creation
void CCalendarEngine::Completed(TInt aError)
{
iWaiter->AsyncStop();
}

// Returns whether or not progress notification is required
TBool CCalendarEngine::NotifyProgress()
{
// Progress notification is required
return ETrue;
}

void CCalendarEngine::SearchCalendar()
{
if (iWaiter->IsStarted()) {
iWaiter->AsyncStop();
}

iCalEntryView = CCalEntryView::NewL(*iCalSession, *this);
iWaiter->Start();

CCalIter* calIter = CCalIter::NewL(*iCalSession);
TBuf8<150> iterUID;
RPointerArray<CCalEntry> calEntryArray;
iterUID = calIter->FirstL();

while (iterUID != KNullDesC8) {
// get entries associated with this UID
iCalEntryView->FetchL(iterUID, calEntryArray);

for (TInt k = 0; k < calEntryArray.Count(); k++) {
// get information from this entry
CCalEntry* calEntry = calEntryArray[k];
iObserver.newEntryFound(calEntry);
}
iterUID = calIter->NextL();
};
calEntryArray.ResetAndDestroy();
delete calIter;
delete iCalEntryView;

It doesn't work, how to instantiate MCalendarObserver?

basically you donot. in Symbian MCalendarObserver is used to help callbacks.

If you donot want to go deep in to symbian.c++ then i suggest you check the "Organizer API" in Qt Mobility

Thanks,

I tried to manage the example and try to connect it with Qt

However,

I found

CCalEntry* CCalHelperEntry::CreateAnnivL()
{
// Create unique ID.
TTime now;
now.HomeTime();
TInt64 seed = now.Int64();
TInt randNum = Math::Rand( seed );
HBufC8* guid = HBufC8::NewLC(KGuidLength);
guid->Des().Num( randNum );

//CCalEntry::EMethodNone means that there's no group scheduling
CCalEntry* anniv = CCalEntry::NewL( CCalEntry::EAnniv, guid,
CCalEntry::EMethodNone, 0 );

CleanupStack::Pop( guid );

CleanupStack::PushL(anniv);
TTime startDate(iDate);
TCalTime time;
time.SetTimeLocalL(startDate);
anniv->SetStartAndEndTimeL(time, time);

if (iAlarm) //if there is a alarm
{ 
delete iAlarmPtr;
iAlarmPtr=NULL;
iAlarmPtr = CCalAlarm::NewL(); 

iAlarmPtr->SetTimeOffset(-iAlarmMinutes.Int());
anniv->SetAlarmL(iAlarmPtr);
}

CleanupStack::Pop(anniv);

return anniv;
}

It introduces error on

anniv->SetStartAndEndTimeL(time, time);

I initialized the helper as follows:

CCalEntry * nulli = NULL;
iEntry = CCalHelperEntry::NewL(nulli);
TTime now;
now.HomeTime();
iEntry->SetValues(_L("Test"),now.DateTime(),EFalse, now.DateTime(),0);
iEntry->SaveValuesL();

Did I so something wrong?

Thanks!
