[comp.sys.mac.programmer] Poly drawing ala MacDraw or SuperPaint?

sund@tde.lth.se (Lars Sundstr|m) (02/19/91)

Is there any general guidelines on how the user should draw poly shapes?

MacDraw and SuperPaint for example mainly differs in three ways: 

1. In MacDraw a new line of a poly isn't drawn before the mouse button
   is released. However, SuperPaint draws a new line directly.

2. In MacDraw it's possible to double click in order to stop the poly
   drawing even if the user clicked in two different positions.

3  In MacDraw it's possible to end the poly drawing by clicking close
   to the first point of the poly. In SuperPaint you have to double
   click no matter where you are and the clicks have to be in the
   same position.

And even stranger, PowerDraw uses the mouse-button-up positions to
create a poly for all but the first point.
