Detect touch event on idle screen..

[amol_benare604]

Hello friends
I have developed an application for s60 5th edition devices.
There is indicator icon I have putted on idle screen showing that the application is running in background.

Now I want to bring my application to foreground by tapping on indicator icon...

For that I have to detect touch event on desktop(idle screen) ...

Can any body plz help me in this case?????

I have searched on this and found that using Animation dll we can do that ... But I am not getting how to do that???

Can anybody suggest me easiest way for this???

Thanks and regards
Amol

How excatly are you drawing the indicator, does it have a Window ?

[amol_benare604]

Yes I have a window... I am drawing image in the 10x10 window...

Then enable the touch events for the window, and start listening events for the RWSession, then when you get Run called, check teh event type.

Hi Amol,

Did you seen AknAppUi class function.....HandleWsEventL.?. In this function you check Pointer event(EEventPointer) or key event in background.

For more info, Have look in SDK or Forum Nokia WIKI :-)

I checked by adding below code in that window for detecting the touch events

void CIndicatorIcon::HandlePointerEventL(const TPointerEvent& aPointerEvent)
	{		
	 // Remember to call base class implementation. Then your child controls
	    // receive pointer events.
	    CCoeControl::HandlePointerEventL(aPointerEvent);
	 
	    // Rest of your code 
	    if (aPointerEvent.iType == TPointerEvent::EButton1Down)
	        {
	        // TODO: What to do when this ui control receives pen down event...
	            TApaTask aThisTask(iEikonEnv->WsSession());
		    aThisTask.SetWgId(CEikonEnv::Static()->RootWin().Identifier());
		   aThisTask.BringToForeground();
	        }
	}

This is working fine on emulator...
But if I deploy same application on actual phone its not working...!!!!

Can you plz tell what will be the possible resons for this???

I have added all Express sign capabilities in my application....

[talk2mks]

HandlePointerEventL function work only when your application in Foreground not in background ... that's why It's work in Emulator because you are testing in foreground....for background....Impelement HandleWsEventL function in your APPUI class....

Thanks again.....

I have added all Express sign capabilities in my application....

Why would you ever do that?

[amol_benare604]

Hi Itomuta
I have added all capabilities bcoz., I know my code need swevent capability and that is in express sign. Every time I add a code, sometimes documentation doesnt mention capabilities... In that case if I miss single capability the code doesnt work on actual device inspite of it works on emulator ...
So to avoid that I have added all capabilies.... It saves my time to find capability requires for the code...

[ltomuta]

It saves my time to find capability requires for the code...

But it complicates your life when you are supposed to cleanup your project for the final certification of the release. It should be easier to hunt down the capability as soon as you add a new feature rather than analyse the full code at the end.

[amol_benare604]

Ok Itomuta
I will take care of this from next implementation...
Thanks for guiding me....
