[Glade-users] how to delete the curves on canvas

[zengqianghit hotmail com (zeng qiang)]

Hi all,
I am using glade-canvas to generate curves by clicking points on the 
canvas.

now if i am not satisfied with several points i have clicked. how can i 
delete the relative part of curve undesired??
i wonder if gtk has the canvas shape delete command??

Thanks very much.
ZQ
