Vibrate on setting item

Hi,
I have a settings view where I have an Binary item, CAknBinaryPopupSettingItem with pop up options as On/Off.
i want the phone to vibrate for some time when the user selects On option from the settings. How can I do this?
I have checked the Vibrate API and also made the vibrate function, but I don't know where to put it.

This below code is from CppExamples of SDK
_LIT(KBinaryText1, "On");
_LIT(KBinaryText2, "Off");

My Settings LoadList() is as follows.
CAknBinaryPopupSettingItem* item10 = new (ELeave) CAknBinaryPopupSettingItem(10, iBinary);
CleanupStack::PushL(item10);
// The same resource id can be used for multiple binary setting pages.
item10->ConstructL(isNumberedStyle, 10, KName10, icons, R_BINARY_SETTING_PAGE, -1, 0, R_POPUP_SETTING_BINARY_TEXTS);

// Load texts dynamically.
texts = item10->EnumeratedTextArray();
texts->ResetAndDestroy();
// Text 1
text = KBinaryText1().AllocLC();
enumText = new (ELeave) CAknEnumeratedText(0, text);
CleanupStack::Pop(text);
CleanupStack::PushL(enumText);
texts->AppendL(enumText);
CleanupStack::Pop(enumText);
// Text 2
text = KBinaryText2().AllocLC();
enumText = new (ELeave) CAknEnumeratedText(1, text);
CleanupStack::Pop(text);
CleanupStack::PushL(enumText);
texts->AppendL(enumText);
CleanupStack::Pop(enumText);

// Sets the correct text visible
item10->LoadL();


void CDynamicSettingListAppView::DoVibrateL( TInt aDuration )
{
CHWRMVibra* vibra = CHWRMVibra::NewLC();

if ( CHWRMVibra::EVibraModeON == vibra->VibraSettings() ) // get vibration setting in the user profile
{
vibra->StartVibraL( aDuration );
}
CleanupStack::PopAndDestroy( vibra );
}
Now where should i use DoVibrate() function so that it vibrates when user choses On option

in general you would not use settings list items to catch user changing them, basically user would change the settings items and then select some otehr action in which you would first load thge setting liost values from the UI components to teh variables associated with them, and then use/save the values.

So you might want to re-think the UI you want to use for user action here. Basically if you would want to catch the event user pressing the setting list itenm, you could try overwriting the HandleSettingPageEventL function.

thanks yucca,
I checked the radiobutton example [url]http://www.developer.nokia.com/Community/Wiki/CS001118_-_Creating_a_radio_button_settings_page[/url]
It is working fine but it has only one setting item(radiobutton), but when the settings page open it directly displays the popup menu of radio button. I have two items ( binarypopup and enumerated ) in my settings page and want them to display and when i click on binarypopup item it should vibrate if it's value is chosen as ON

(Refer to code below) when I try to use item10->SetSettingPageObserver() or item10->ExecuteLD() I am getting error as undefined idetified on both functions. I have my Settingview inherited from CCoecontrol and MAknSettingPageObserver
What should I do to resolve it?

basically just take the example you pointerd to, add your controls into the resource, and check in HandleSettingPageEventL when your selected item is clicked by the user.

I tried that, but HandleSettingPageEventL is never called. I guess we have to add these 2 lines below ( as in Radiobutton example which is working fine in radio button) but when i put in my code these functions are 'undefined identifier'

item->SetSettingPageObserver(this);
item->ExecuteLD(CAknSettingPage::EUpdateWhenChanged);

I am thinking it's because of the way the item is created
CAknRadioButtonSettingPage* item=new (ELeave) CAknRadioButtonSettingPage(R_EXAMPLE_SETTING_PAGE,iSelection, array);
and
CAknEnumeratedTextPopupSettingItem* item1= new (ELeave) CAknEnumeratedTextPopupSettingItem(9, iEnumText);
??

Uups, gotta say that I missed how the example was made, I have to say that I'm not certain what the person who made that was thinking or going after. I would suggest actually using the HandleSettingPageEventL inside the settings list, and not in any external class. Then it would be called nicely without any additional things.

It is indeed inside Setting List
SettingList::ConstructL(){
...
iItemList = new (ELeave) CAknSettingItemList;
iItemList->ConstructFromResourceL(R_DYNAMIC_LIST);
LoadListL();
...
}
SettingList::LoadList(){
//Radio button from example
CDesCArrayFlat *array = CreateRadionButtonOptionsLC();
CAknRadioButtonSettingPage* dialog =
new (ELeave) CAknRadioButtonSettingPage(R_EXAMPLE_SETTING_PAGE, iSelection, array);
CleanupStack::PushL(dialog);
dialog->ConstructL();
CleanupStack::Pop();//dialog
dialog->SetSettingPageObserver(this);
dialog->ExecuteLD(CAknSettingPage::EUpdateWhenChanged);
CleanupStack::PopAndDestroy(); //array

//from Dynamic Setting List Example
TBool isNumberedStyle = iItemList->IsNumberedStyle();
CArrayPtr<CGulIcon>* icons = iItemList->ListBox()->ItemDrawer()->FormattedCellData()->IconArray();

//Binary popup setting item
CAknBinaryPopupSettingItem* item10 = new (ELeave) CAknBinaryPopupSettingItem(10, iBinary);
CleanupStack::PushL(item10);
// The same resource id can be used for multiple binary setting pages.
item10->ConstructL(isNumberedStyle, 10, KName10, icons, R_BINARY_SETTING_PAGE, -1, 0, R_POPUP_SETTING_BINARY_TEXTS);

// Load texts dynamically.
texts = item10->EnumeratedTextArray();
texts->ResetAndDestroy();
// Text 1
text = KBinaryText1().AllocLC();
enumText = new (ELeave) CAknEnumeratedText(0, text);
CleanupStack::Pop(text);
CleanupStack::PushL(enumText);
texts->AppendL(enumText);
CleanupStack::Pop(enumText);
// Text 2
text = KBinaryText2().AllocLC();
enumText = new (ELeave) CAknEnumeratedText(1, text);
CleanupStack::Pop(text);
CleanupStack::PushL(enumText);
texts->AppendL(enumText);
CleanupStack::Pop(enumText);

item10->LoadL();

iItemList->SettingItemArray()->AppendL(item9);
CleanupStack::Pop(item9);
}

Now when i open this view, radio button options pop up at first and when i select any of the options HandleSettingPageEventL() is indeed called, but when the Binary option window is shown and I change the options On/Off HandleSettingPageEventL () isn't called.
SettingList.h is inherited from Ccoecontrol and MAknSettingPageObserver

I would suggest debugging ti again, indeed it should be called for all controls.

I have debugged it, still can't figure out the problem. Any help ??
Or if anyone can provide any alternate solution for vibrating the phone when the user selects a option in Settings ( for eg: in CAknBinaryPopupSettingItem)
