I am a new Maemo developer.
I won't to send my application to background.
I tried to hide the Main Window using "QWidget::hide ()", and it success to hide the application but i failed to show it again.
I also tried to minimize the Main Window using "QWidget::setWindowState ( Qt::WindowMinimized )" but it not worked as i won't, it make the application in bottom of other applications.
I won't any method to send the application to background or hide it and show it again.
