[maemo-developers] How to activate application

[From: Artem Semenov]

Hi All,
Does anybody know how can I activate QT application in maemo?

I have a desktop widget and I want to activate main application when
user clicks on widget.
I use OSSO lib in order to send event from widget to my QT application
and when event is received by main application I perform the following
actions for main window:

{
raise();
activateWindow();
setWindowState( Qt::WindowActive );
}

but nothing happens if application is already open.

Thanks,
Artem
