[Squeakland] pen trail as object (in OLPC)

[Randy Heiland]

Replying to my own post, I did finally discover that I could use the  =

'fill & border' category of my Line/Circle-constructed polygon object  =

to increase its "pen size" (borderWidth) and color (borderColor).   =

However, it really is a different type of object than one created via  =

painting, isn't it?  E.g., in my case, I created a closed polygon and  =

then would have liked to "fill" it using the paint bucket in the  =

paint palette, however, their is no Repaint handle for my constructed  =

polygonal object.  Neither does the Line's color tile in the fill &  =

border "fill in" my closed polygon.  Perhaps for the project I had in  =

mind, I'm better off returning to the original suggestion of normal  =

painting with the trick of "erase pixels of color".
