Alarm like notification in N9

[vinothg]

Hi,

When i set an alarm in N9, a notification is seen on the top of the screen "Time Left until alarm". I have seen few third party apps (Screen capture) do the same thing when settings are saved. I wanted to add this functionality into my app.

What kind of notification is it ? An example code would be of great use.

Regards,
Vinoth

Check MNotification.

That notification you see in screen capture and clock application is an Information Banner. Please see above link for QML information banner.

The above link points to the documentation of the MBanner class

Here's how to launch an information banner from code:

MBanner *infoBanner = new MBanner();
infoBanner->setStyleName(MBannerType::InformationBanner);
infoBanner->setTitle("Info banner with so much information that the text wraps in portrait");
infoBanner->appear(scene(), MSceneWindow:estroyWhenDone);

Hope this helps!

Oops.. Sorry for misunderstanding your question.

Those application specific notifications are banners and (as suggested below) you can create it in Qt -MeeGo application using "MBanner" and in QML using QML InfoBanner Element.

Thanks. I was looking exactly for this. What is scene() ? It says scene() is not declared in this scope. I saw the API declaration and it expects QGraphicsScene. I instantiated an object of type QGraphicsScene but at run time it says "scene has no scene manager".

This is my first Meego project so i still don't understand many things.

I tried to do it using QML but it failed at run time with message "X Error: BadDamage (invalid Damage parameter) 153"

I just wanted to show a simple message like "File saved successfully". Is there any other way to do it. I am looking for a Toast like functionality from Android.

QML:

import QtQuick 1.1
import com.nokia.meego 1.0
import com.nokia.extras 1.1

PageStackWindow {
id: appWindow
InfoBanner {
id: banner
text: "Fyuck Meego"
timerShowTime: 3000
}
}

The X Error message is not related to usage of Info banners.
Your code is okay, but if you don't call banner.show() your banner won't ever be shown!

Hi,

I need to use MBanner, but for using it I need to get QGraphicsScene for MBanner->appear() method. And it's not clear how to get scene if my application has no own window. Any hint?

Are u using QT or QML ? Incase of QML you can check the below posts to display a banner.

[AlxKara]

No. My application doesn't have own window. Anyway, if you meen InfoBanner: this banner works only inside application window.

Hi,
MBanner is the MeeGoTouch class used by QML InfoBanner.
Both are displayed in a graphics view, so both require a graphics scene.
A declarative view is basically a graphics view, so you can get the scene using scene() method.

Since your app doesn' have any GUI you CANNOT use any of those banners, but you should be able to use MNotification class.
MNotification dispalys a banner without requiring a window.
This is possible because the MNotification banner belongs to System UI (which is a process different from your app).
Communication between your app and System UI makes use of DBus messages.

You can reaad more about MNotification in this forum, it's covered by several threads and you can browse the reference manual at http://harmattan-dev.nokia.com/docs/...JtZWVnb3RvdWNo

Wanted to share my experience with MNotification beside described in MNotification reference.

To use MNotification you must instanciate MComponentData in your main.cpp:
#include <MComponentData>
...
MComponentData::createInstance(argc, argv);

To show a banner, not a notification in the Notification Feed view, you will have to use MNotification::DeviceEvent event type.

If you apparently want for something to happen when a user taps your banner, you will have to create a D-Bus adaptor to use it with setAction() method because the MNotification banner will be shown outside of your application process.

Hi conxt,
If you have some spare time it would be nice to see a minimal app which make use of DBus adaptors with MNotification in our wiki pages.

Hi, thank you for your good tips. Could I use system-wide notification to status bar, such as new email arrival notification? I'd like to use it from QML easily such as InfoBanner.
