    \class CHbDeviceNotificationDialogSymbian

    \brief CHbDeviceNotificationDialogSymbian is a Symbian implementation of HbDeviceNotificationDialog.

    It is a client interface for s60 native application to show a non-modal dialog on top of applications when

    HbDeviceNotificationDialog can not be used.

    CHbDeviceNotificationDialogSymbian provides similar interface and functionality as HbDeviceNotificationDialog.

    Main difference is that signals are replaced by an observer interface CHbDeviceNotificationDialogSymbianObserver.

    For the content CHbDeviceNotificationDialogSymbian provides two rows of text, an image or an animation and for the usage

    same rules as for the HbDeviceNotificationDialog apply. Dialog is shown when show() is called. It is recommended that 

    the dialog data is initialized before calling ShowL() or UpdateL() methods, because those methods use interprocess communication.

    \code

    Following code snippet creates a device notification dialog containing title, text and icon.

    _LIT(KDialogText, "Dialog text");

    _LIT(KDialogTitle, "Dialog title");

    _LIT(KDialogIcon, "note_info.svg");

    CHbDeviceNotificationDialogSymbian* dialog = CHbDeviceNotificationDialogSymbian::NewL();

    CleanupStack::PushL(dialog);

    dialog->SetTextL(KDialogText);

    dialog->SetTitleL(KDialogTitle);

    dialog->SetIconNameL(KDialogIcon);

    dialog->Show();

    CleanupStack::PopAndDestroy(dialog);

    \endcode

    or equivalent dialog can be created using one of the provided convenience methods:

    \code

    _LIT(KDialogText, "Dialog text");

    _LIT(KDialogTitle, "Dialog title");

    _LIT(KDialogIcon, "note_info.svg");

    CHbDeviceNotificationDialogSymbian::Notification(KDialogIcon, KDialogText, KDialogTitle);

    \endcode

    When using convenience methods, it is not possible to receive user interaction events, because the 

    HbDeviceNotificationDialog instance is destroyed when the call returns. Ownership and handling of the

    dialog is transferred to HbDeviceDialog framework. Also dialog can not be closed nor updated.

    Below is an example of receiving user interaction events from device notification dialog. With following example 

    user is able to receive activated and close events. Note that dialog is cancelled, if it goes out of scope.

    \code

    _LIT(KDialogText, "Dialog text");

    _LIT(KDialogTitle, "Dialog title");

    _LIT(KDialogIcon, "note_info.svg");

    iDialog = CHbDeviceNotificationDialogSymbian::NewL(this);

    iDialog->SetTextL(KDialogText);

    iDialog->SetTitleL(KDialogTitle);

    iDialog->SetIconNameL(KDialogIcon);

    iDialog->ShowL();

    \endcode

    CHbDeviceNotificationDialogSymbian supports. 

    Supported formats are the following.

    - GIF (.gif)

    - MNG (.mng)

	- Frame animations

	There is a built-in support for GIF and MNG animations. 

	Frame animations can be created by following way:

	\code

	Create an animation definition file.	

	<animations>

		<icon name="frame_anim_looping" playmode="loop">

			<frame duration="100">c:\icon1.svg</frame>

			<frame duration="200">c:\icon2.svg</frame>

			<frame duration="300">c:\icon3.svg</frame>

		</icon>

	</animations>	

	Create CHbDeviceNotificationDialogSymbian in a way described before and

	set definition file and animation's logical name.

	_LIT(KAnimationDefinitionXML, "C:\animation.axml");	

	_LITK(KLogicalIconName, "frame_anim_looping");

	iDialog->SetAnimationDefinitionL(KAnimationDefinitionXML);

	iDialog->SetIconNameL(KIconName);

	iDialog->ShowL();		

	\endcode

	\sa HbIconAnimationManager::addDefinitionFile

	\note Animation definition files must be stored to a place where they

	can be accessed.
