            clickedElement = source; -- store the clicked element in a global variable
            local elementPos = { DGS:dgsGetPosition( source, false ) };

        end
    end
);

addEventHandler( "onDgsMouseUp", root,
    function ( btn, x, y )
        if btn == "left" then
            clickedElement = nil;
        end
    end
);

addEventHandler( "onDgsMouseMove", root,
    function ( x, y )
        if clickedElement then
            DGS:dgsSetPosition( clickedElement, x - offsetPos[ 1 ], y - offsetPos[ 2 ], false );
