hello Joh im having difficulty in adding new widgets

i think this is more of a Qt specific question but what command can i use to set the position of my widgets on my scene?

i have added widgets made via Qt designer perfectly fine. but now i want to make them movable with mouse dragging.

also my widget doesn't have a title like in the example shown http://doc.trolltech.com/qq/qq26-openglcanvas.html

how do i make them movable via mouse dragging and how do i show a title (eg "Instructions")
