Strange PasteUpMorph>>drawOn:

I found this method a bit strange. As it is showed by its code sample
below, grid will be rendered only if gridding is on.

Do I miss something?

(self griddingOn and: [self gridVisible])
        ifTrue:
                [aCanvas fillRectangle: self bounds
[...]

That sounds like exactly what I'd expect. What's strange?

griddingOn is a flag to know if point are to be locked to the grid
position (using the PasteUpMorph>>gridPoint: method)

gridVisible is a flag to tell if the grid is visible.

In the drawOn: method it looks to me a grid is display only if the 1.
gridding is activated, 2. the grid is set to be visible.

Indeed, this is the behavior I noted when I try to use the grid and the
gridding in my code. I try to get only one of these feature but I have
to take both. As a result I have to duplicate the griddingFlag in my
code to know if I want or not to use gridding.

When you say "duplicate", do you mean that you are having your own
code draw the grid, duplicating some code from PasteUpMorph>>drawOn: ?
Or do you mean that you are unable to access the value of griddingOn?

I feel as if I'm missing your meaning. I can't be sure whether you're
asking how to do something, reporting a bug, or something else. If it
seems to you that you haven't been heard, feel free to repeat your
request in French (or whatever language you're best at). Although I
won't be able to answer in French, someone else on the list may be
able to help.

Good luck with it!

Hum, yes, it is that. May be the grid was design that way, which at
first looks to me as a wrong design. May be I am the first one to
display a grid without the gridding (magnetic grid feaure), then later I
 can activate gridding, wheter the grid is visible or not. Of course it
was not difficult to make it possible, but to do that I have to
duplicated in my own class the griddingFlag which I am not that much
happy with. But of course it is just a minor problem.

No, I wrote: "I have to duplicate the griddingFlag", not to duplicate
code. The griddingOn as to be true if you want to display the grid, it
looks to me as a duplicated behavior of the gridVisible flag.

I want to have some exchange regarding this strange situation with grid
and gridding. I know where to report bug, don't worry.

I am afraid you will have to get used with my English.

Thanks for your time,
