Follow-up Comment #5, bug #48186 (project octave):

Thanks, Mike. Sorry, this bug report is confusing because I mentioned two
separate issues and the title I chose relate to the second issue that is of
lesser importance.

I agree that deleting a deleted handle is not a primary problem and can be
left for later when/if graphics handles are implemented as objects.

There is still the issue that the following code returns an error:


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


while it runs OK even for Matlab versions that implement graphics handles as
double.
