When casting to PicassoLine or PicassoRectangle it pop up:
(Picasso:10091): GLib-GObject-WARNING **: invalid cast from
`PicassoPicassoItem' to `PicassoPicassoRectangle' (or PicassoPicassoLine)
Try changing
((PicassoLine) canvas.preview).....
to
(canvas.preview as PicassoLine)....
If that still gives you warnings, try declaring
PicassoItem class as *abstract* so that you don't
accidentally do something like this:
var type = ItemType.NONE;
PicassoItem item = new PicassoItem(0, 0, type); // big mistake!
item.type = ItemType.CIRCLE; // big mistake!
By the way, I'm sure you don't need ItemType.
Vala supports runtime class check.

PicassoLine without having PicassoLine initialized...
