Hello Samuel,

If I understand correctly, it might be sufficient to set `gce` on when a 
graphical object is
selected (not edited but just selected), no ?

  * Driving the focus for the data curve editor of a given figure: If
    its data curve editor in "on", AND
      o if gce() is a polyline in the considered figure, then, indeed,
        the default edited curve could be set to gce(). This would
        allow to set the "java focus" with a command line.
      o If gce() is not a polyline or is a polyline in another figure
        (whose curve editor is off, or that has not the "java
        focus"?), then the editor of the considered figure may stand
        behaving has it presently does (i have no proposal to clarify
        this).

  * Setting gce() from the editor :
      o if the editing mode is off and we select a curve (turning
        grey) : no, gce() shall not be set to the selected (greyed)
        curve. This would trigger major back-compatibility issues.
      o if the editing mode is on :
          + if the interactive selection is done in gca() : yes,
            synchronizing gce() to the currently edited curve would
            answer to the issue. This synchronization would be more
            intuitive than the current behavior that has 2 distinct
            focus : Scilab's one (with gce()), and java one (with
            interactions).
          + otherwise : no, because this would compel as well to set
            gca() to the java focus. This would bring major BC issues.

I don't know whether the editor is able to edit other types of objects than polylines. If so, the proposed behavior could be extended to them.

I hope that this analysis is clear enough (sorry for the length). However, it may still miss important things... Any confirmation would be welcome.

Regards
Samuel

As often, other ideas/considerations come with a delay ;) :

 * If we interact (selection or even edition) with a curve in a figure
   that is not gcf(), then, when we will scf() to it, the default gce()
   should become the last edited curve. I am not sure that it is
   already the case (too many tests done forget first ones...;)

Samuel
