[vwnc] A question on GraphicsContext's ...

I have a displayable object which gets passed
    obj displayOn: aGc

I do this
    gc := aGc copy.
    gc paint: ColorValue yellow.
    gc displayRectangle: aRectangle

Then all subsequent lines displayed using the original GraphicsContext
are yellow ???

I thought the "copy" would prevent that?

The original paint is "SymbolicPaint foreground"

Any suggestions?

Perhaps #copy is not deep enough and you need a #deepCopy instead?

Thanks -- you were close -- at least you indicated it should not do what its doing.

I had an instance-variable "colour" and much later (after writing the code a few years ago)
I added a method that used "colour" as a temp-variable -- fixed that and now it works as expected
