Hi Laure,
data structures are displayed according to their position in the list,
meaning that objects with a higher index will be shown on top of objects
with a lower index.
There is, however, a bug/inconsistency:
If you move (not only click) a scalar, it will always show on top of any
othe
Dear all,
I have a quick question about the object placement in data structures.
What determines which object lies on top, and which goes in the
background? Instantiation and creation order don't seem to affect the
placement order (but maybe that's also a problem in my patch…)
Thanks!

Laure
Note that [append] will update its pointer to point to the new scalar.
The new pointer is also output. So for consecutive appends you only need
to send a pointer once in the beginning.

Everything is ok now for me. The last created scalar is the last one to

Hi
From previous old discussion (

I understood that datastructure z-orderdrawing depends of creation
order, but when you programmatically create a new scalar (with [traverse

Just thought of this after sending the previous mail. I can't try this

- get the scalar's x/y coordinates
- use mouse messages to select and delete anything over that pixel.
Drawbacks:
- will delete anything else over that pixel (affects the selectab

Thanks for your testing!
The lag appears on my computer already with the patch i sent with the
1050 scalars. It shows when i open the patch, create any object, say a
[float] and try to move it around.
With more scalars it can become even worse. You can test it with the
