how can I draw a arc with goocanvasmm

["Klaus Rudolph" <lts-rudolph gmx de>]

Hi all,

is it possible to draw only a part of a circle with goocanvasmm:

m_ellipse = Goocanvas::Ellipse::create( x, y, radius.x, radius.y );
root->add_child( m_ellipse );

works fine and draw a full circle.

How can I draw only an arc?

Is that based on a circle or must I calculate a long list of points for a polyline? If so, is there an 
example anywhere?

Regards
 Klaus
