Key(s) Simulation "Globally"

[ssn.kishore]

Hello Folks,

I want to simulate all the keys on the keypad for the Nokia 73 (basically S603rd edition) globally. I am not able to simulate any key other than the "RED" key. The following code works,

RWsSession wsSession = CCoeEnv::Static()->WsSession();
TKeyEvent keyEvent;
keyEvent.iCode = EKeyNo;  //member of TKeyCode
keyEvent.iScanCode = EStdKeyNo;
keyEvent.iModifiers = 0;
keyEvent.iRepeats = 0;
wsSession.SimulateKeyEvent(keyEvent);
wsSession.Flush();

Is it not possible to simulate all the keys? If it is, then can someone point me towards a "sane" mapping table for the keys?
For e.g. KEY: Numeric Key 1 ScanCode: ABC Code = XYZ

Thanks in advance.

Hi,

Try to debug your application and put a break point in OfferKeyEventL and when you press any key you can find the keycode in debug window.

Thanks for the reply Krish!

I have the scancodes I want to simulate. For e.g. the scan code printed when I press the "1" key on the numeric keypad is 49, while the scan code for the same given in e32keys.h is EStdKeyNkp1. Secondly, there is no corresponding value to fill in the iCode member of the TKeyEvent.

Lastly, the Symbian website is down

the link i have given is from SDK help.

Hi,
Implement HandleWsEventL() in your AppUi and when you will debug your application keeping a breakpoint you can get all the codes for all of the keys in numeric keypad. Anyways first check the SDK help link which skumar_rao has provided. You can get that in your SDK help no need for going through web link.

Hi,

Lately even I have noticed that iCode is always zero for all the key events. Any one knows anything about this ?

[Paul.Todd]

If the TEventCode code is EEventKeyUp or EEventKeyDown then the iCode will be 0

Hi Paul,

I was debugging and I have noticed that for all the three events types the iCode was zero anyways I will debug once again and post the result.

It is OK that iCode is zero for EEventKeyDown and EEventKeyUp. However it should be non-zero for EEventKey. Where have you tested that?

[ssn.kishore]

RWsSession wsSession = CCoeEnv::Static()->WsSession();
TKeyEvent keyEvent;
keyEvent.iCode = 49;  //member of TKeyCode
keyEvent.iScanCode = 49;
keyEvent.iModifiers = 1;
keyEvent.iRepeats = 0;
wsSession.SimulateKeyEvent(keyEvent);
wsSession.Flush();

Why doesn't the above code simulate the "1" numeric key?

49 is the scan code and iCode for it I received in the OfferKeyEventL() function of my View class. Am I doing something wrong?

@Yogpan, the HandleWsSessionEventL() example given on Wiki doesn't seem to work for me

Hi,
Can you try with the iCode to be put as 0. It seems that the iCode for the keys is coming as 0. And what problem did u face in putting HandleWsEventL() in your AppUi. It has the parameter as TWsEvent form which you can get the Key() and then get all the necessary values.

Hi Yogpan,

I don't have a problem retrieving the values of the keys being pressed, they can be retrieved in OfferKeyEventL() itself.

On this link, the guy claims that he has successfully "simulated" numeric keys. I am trying to get his code working, but it ain't budging!

I was able to simulate the "green key" using the following code,

RWsSession sess=CCoeEnv::Static()->WsSession();
TWsEvent event;
TInt id = sess.FindWindowGroupIdentifier( 0, _L("*Telephone*") );
event.SetType(EEventKey);
event.SetTimeNow();
event.Key()->iCode = EKeyYes;
event.Key()->iModifiers = 1;
event.Key()->iRepeats = 0;
event.Key()->iScanCode = EStdKeyYes;
sess.SendEventToWindowGroup( id, event );

I wish to "replay" all the recorded keys i.e. the sequence of key presses from time A to time B programmatically.

Could you tell me what is the iCode for the scan code EStdKeyNkp1 (scan code for numeric 1) ?

[nuker85]

The reason why you get 49 as a "1" key is that it is decimal value for character "1" in ASCII.
Here you can find all codes:

good luck

Hi,
I understood your requirement but have you tried to get all the values of the key press by logging. You can write a small code to check this. Meanwhile I will also try to retreive these values for you.
