Bring widget foreground

[ghimyap]

Hi everyone.Its my first day here. I hope to use some help....

I created an alarm widget whereby after setting the time the widget will send to background.
May I know how to automatically bring the widget foreground programatically that has been sent to background using

function goToBackground()
{
widget.openApplication(0x102750F0);
}

The widget must auto open back(foreground) upon my function :setTimeout(60000).

Thanks in advance

Hi ghimyap,

in order to bring a widget to foreground, you can use the very same approach you use to send it to background, so using the openApplication() method, but passing the widget's UID to this method, instead of the home/standby application's one.

Since the widget does not automatically know its UID, you first have to retrieve that, and you can do it by using the AppManager API (available on WRT 1.1 runtime). By listing the installed applications, you can find your widget's data, and so also its UID.

Please note also that on devices with BrowserNG version older than 7.1.17501, timers of background widgets are not triggered, so your approach will not work on these devices:

Hope this helps,

Hi pit

Thanks for your solution. Pls tell me more on how to launch/get to AppManagerAPI on WRT1.1.
I am very new to all this program and software.

Currently using Aptana Studio 2.0 to program my widget and run on SDK S60 Nokia Symbian OS, 5th edition emulator. So in this case will my setTimer() function still work ??


Thanks Thanks Thanks

Hi ghimyap,

you should use the following AppManager API's methods:
* GetList to get the list of installed apps, where you have to look for your widget
* LaunchApp to launch your widget (here also widget.openApplication() would work)

About the issue, as told on the Wiki page, background timers work on devices with browsers newer than 7.1.17501 version. Also note that, if the user has at least one homescreen widget, then background timers will not be fired at all.

Hi,

* GetList to get the list of installed apps, where you have to look for your widget
* LaunchApp to launch your widget (here also widget.openApplication() would work)

If the need is to only obtain the UID of some specific application, I'd recommend using the great Y-Tasks app from DrJukka (http://www.drjukka.com/YTasks.html) if possible. That app is a great tool and is able to tell much more about installed applications than just their UIDs.

Hi Pit

Can I have an example of the widget of the 2 methods in helping me to bring my widget foreground once again.
I have tried but to no avail =(.

Thanks thanks

Hi ghimyap,

you can find the code to list installed applications here:

http://wiki.forum.nokia.com/index.ph...d_applications

By using this code, you have to look for your widget by checking all the applications' names.

Once you've found it, you can easily retrieve its UID and then use it in your widget. Also, you can store it as a preference, so avoiding the need to list the installed applications each time.

Hope it helps,
Pit
