However, the findobj() fix that has been recently merged by Clément
restores only the speed of tags search. findbobj() won't be further
fixed as it provides many useful features which were missing to its
(fast but poor) previous version.
Indeed, using findobj to get the handle of a figure knowing its id is
the most complicated that one can imagine. It sounds to me like the
affirmation: « why make it simple when it can be made complicated »... I
mean, close() has to be fixed to use scf() as proposed in this thread.
Sometimes adding useful and needed features can degrade the speed of a
function (you can't make an omelette without breaking eggs). Finding
handles given their tag has its original performance with this patch.
But I repeat that h=findobj('figure_id",id) should be avoided in favour
of h=scf(id), until findobj() is completely rewritten in C++ (which is
planned).
Moreover nobody was complaining about xdel() and making it deprecated
was never discussed by the community. Many people don't use Scilab any
more because it misses features. So Scilab needs features, not
absurde/arbitrary cleaning . A word to the wise...

Hi,
This is fixed for the next release:
https://codereview.scilab.org/#/c/21803/ [1]
In the meantime, if you really need it you can download the patched
version of findobj.

Hello Claus,
Le 21/01/2022 à 20:58, Claus Futtrup a écrit : Hi Scilabers
Today I tried to replace xdel(winsid()) in one of my scripts with
close(winsid()) because Scilab shows a warning in the console:
Warning: Feature xdel(...) is obsolete and will be permanently removed
in Scilab 6.2
Warning: Please use close(...) instead.
I am negatively surprised that the close() command takes a long time to
execute with 5-10 windows open (a few seconds per window). The xdel()
command can do it in a split second.
The issue comes not from close() but from the change of findobj() that
it calls [2], noticeably to perform findobj("figure_id",id) in 6.1.1.
It does not impact only [3] close() for this case, that was processed
as a special accelerated case [4] in the former findobj().
This downgrading was reported [5] 7 months before releasing 6.1.1, and
knowingly ignored, while it is perfectly fixable by restoring the fast
special case.
What is the motivation for replacing xdel with close?
Both do the same thing. Scilab does not need duplicates.
Regards
Samuel
