Re: A few notes on porting Tcl/Tk 8.6 → 9

I tried adding this to the wiki page:

```
## Canvas outline default has changed

When creating a canvas polygon in Tk 8.6 no outline is drawn by default.
For Tk 9 the default is to draw a 1 pixel black line. To get the old
behavior, create with the option `-outline ""`.
```

Incidentally, is it possible to change email address on core.tcl-lang.org?
When I click my username it offers options to change site skin, manage
cookies and change password, but not to change email.

PS My ISP has now stopped supporting newsgroup access.
And a few years ago Google stopped supporting them.
I really wish there was a general Tcl/Tk mailing list that could be
used.

 
 
Mark,
thanks for you effort.
The porting wiki pages are:
 
https://core.tcl-lang.org/tcl/wiki?name=Migrating+scripts+to+Tcl+9&p
https://core.tcl-lang.org/tk/wiki?name=Migrating+scripts+to+Tk+9&p
 
The -outline is not mentioned there. I suppose, this is a bug.
May you file a report?
If it is not a bug, it would be great to add it to the wiki page.
 
Thanks for all,
Harald
