Remove Taskbar in mini2440

Hello everyone,
I have created an application that runs at startup. (I am running Linux)
I want user to see this application only.
But, I want to get rid of the taskbar appearing at the bottom. 

Please suggest me a solution for this. . .

In your main.cpp or whatever file you use to instantiate your QWidget
object.
use:
frmMyWidget->showFullScreen();
rather than:
frmMyWidget->show();
