Re: [Scilab-users] Graphics: Current figure and current entity

Hello,
I have several graphic windows and in some of them, there are several
“Axes” (and several curves for each “Axes”).
I can’t find in “Scilab Help” if the “current axes” is always in the
hierarchy of the “current entity”, and similarly if the “current
figure” is always in the hierarchy of the “current axes”.
Good question. Let's test it :
1. sca(ax) sets the current figure to the one homing the ax axes:
--> scf(0); plot(1:10); e0 = gce(); ax0 = gca();
--> scf(1); plot(1:10); e1 = gce(); ax1 = gca();
--> sca(ax0);
--> gcf().figure_id
ans =
0.
--> sca(ax1);
--> gcf().figure_id
ans =
1.
2. set("current_entity", h) does NOT set the current figure to the one
homing the targeted entity:
--> scf(0); plot(1:10); e0 = gce(); ax0 = gca();
--> scf(1); plot(1:10); e1 = gce(); ax1 = gca();
--> set("current_entity", e0);
--> gcf().figure_id
ans =
1.
--> gca().parent.figure_id
ans =
1.
So now we can answer to your questions:
I can’t find in “Scilab Help” if the “current axes” is always in the
hierarchy of the “current entity”,
Almost never.
and similarly if the “current figure” is always in the hierarchy of
the “current axes”.
Yes it is.
If this was true, I suggest to mention it in the “Graphics Entities”
section.
Right, the sca() and set() pages could be clarified about this.
If not, is there a simple way to obtain the handle of the figure where
the “current entity” is ?
I tried the following, which seems to work :
G_f = gce().parent;
while get(G_f,”type”)~=”Figure”,
G_f = G_f.parent;
end;
Yes, in short:
G_f = gce();
while G_f.type ~= ”Figure”, G_f = G_f.parent; end
that will work even when the initial G_f is already a figure.

[Scilab-users] Native file and directory chooser under macOS
Hi, I think that macOS have been bothered by the Swing file/directory chooser since Java is used in Scilab. Under Windows or Linux these widgets are native (or almost native) and allow to simply select a disk, go to home directory, ... I have been working on this problem and found a solution which took some time to be applied to every places where it may be applicable (Scinotes, Xcos, graphical export, ...). You can experiment this new feature by downloading the new build, available at the usual macOS Scilab page: https://www.utc.fr/~mottelet/scilab/download/branch-6.1/scilab-branch-6.1-x86_64-nativeFileChooser.dmg Enjoy ! -- Stéphane Mottelet Ingénieur de recherche EA 4297 Transformations Intégrées de la Matière Renouvelable Département Génie des Procédés Industriels Sorbonne Universités - Université de Technologie de Compiègne CS 60319, 60203 Compiègne cedex Tel : +33(0)344234688 http://www.utc.fr/~mottelet ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
Re: [Scilab-users] Graphics: Current figure and current entity
Hello Denis, I don’t think Scilab provide a function to retrieve the parent figure of an entity ; could you open a bug with this wish ? Note: internally, there is already a non-iterative O(1) way to retrieve it.
