[Octave-bug-tracker] [bug #48186] delete(allchild(fig)) in a "deletefcn" callback raises error

[Guillaume]

Follow-up Comment #8, bug #48186 (project octave):

Thanks. I notice two things: the first one is that the error depends on the
order in which the two uipanels are created. The following returns an error
with Octave:


F = figure('Units','normalized');
U1 = uipanel(F,'Position',[0 0 0.45 1],
'DeleteFcn','allchild(gcbf),delete(allchild(gcbf))')
U2 = uipanel(F,'Position',[0.55 0 0.45 1])
U = allchild(F)
close(F)


while this runs fine:


F = figure('Units','normalized');
U1 = uipanel(F,'Position',[0.55 0 0.45 1])
U2 = uipanel(F,'Position',[0 0 0.45 1],
'DeleteFcn','allchild(gcbf),delete(allchild(gcbf))')
U = allchild(F)
close(F)


Matlab behaviour follows in the next comment.
