aaaaaahhh come on ... I am not THAT lazy :D of course I have searched it before asking. Unless I am blind I see loads of bezier methods, none that detects whether a point belong to a curve. But now you mention it I think I remember squeak was able to do add points to a curve via click or something similar, because thats what I wan to do. So I will take a look at it , most probably there is a method in there that does this.
I want the user to click on a curve or line and there a new control point will be placed that will allow the user to shape the line or curve to a finer detail. A standard feature for all vector editors , 3d editors, even image editors. I am sorry if I miss something obvious here, its not laziness , its most likely stupidity or just the fact I am very new with this. This is the first time I try to make a vector editor.Again thank you all for trying to help me, you have done already a lot.
