update Octave Project Developers copyright for the new year
In files that have the "Octave Project Developers" copyright notice,
update for 2021.
In all .txi and .texi files except gpl.txi and gpl.texi in the
doc/liboctave and doc/interpreter directories, change the copyright
to "Octave Project Developers", the same as used for other source
files. Update copyright notices for 2022 (not done since 2019). For
gpl.txi and gpl.texi, change the copyright notice to be "Free Software
Foundation, Inc." and leave the date at 2007 only because this file
only contains the text of the GPL, not anything created by the Octave
Project Developers.
Add Paul Thomas to contributors.in.

This is equivalent ## to @code{close (gcf)}. If the input @var{h} is a graphic handle, or vector ## of graphics handles, then close each figure in @var{h}. The figure to ## close may also be specified by name @var{figname} which is matched against ## the @qcode{"Name"} property of all figures. ## ## If the argument @qcode{"all"} is given then all figures with visible handles ## (HandleVisibility = @qcode{"on"}) are closed. ## ## If the additional argument @qcode{"hidden"} is given then all figures, ## including hidden ones, are closed. ## ## If the additional argument @qcode{"force"} is given then figures are closed ## even when @qcode{"closerequestfcn"} has been altered to prevent closing the ## window. ## ## Implementation Note: @code{close} operates by making the handle @var{h} the ## current figure, and then calling the function specified by the ## @qcode{"closerequestfcn"} property of the figure. By default, the function ## @code{closereq} is used. It is possible that the function invoked will ## delay or abort removing the figure. To remove a figure without executing ## any callback functions use @code{delete}. When writing a callback function ## to close a window do not use @code{close} to avoid recursion. ## ## @seealso{closereq, delete} ## @end deftypefn function retval = close (arg1, arg2) figs = []; if (nargin == 0) ## Close current figure. ## Can't use gcf because it opens a new plot window if one does not exist. figs = get (0, "currentfigure"); if (figs == 0) # don't call close on root object figs = []; endif elseif (nargin == 1) if (ischar (arg1)) if (strcmpi (arg1, "all")) figs = get (0, "children"); figs = figs(isfigure (figs)); else figs = findall ("-depth", 1, "name", arg1, "type", "figure"); endif elseif (any (isfigure (arg1))) figs = arg1(isfigure (arg1)); elseif (isempty (arg1)) figs = []; # Silently accept null argument for Matlab compatibility else error ('close: first argument must be "all", a figure handle, or a figure name'); endif elseif (ischar (arg2) && (strcmpi (arg2, "hidden") || strcmpi (arg2, "force"))) if (ischar (arg1)) if (strcmpi (arg1, "all")) figs = allchild (0); figs = figs(isfigure (figs)); else figs = findall ("-depth", 1, "name", arg1, "type", "figure"); endif elseif (any (isfigure (arg1))) figs = arg1(isfigure (arg1)); elseif (isempty (arg1)) figs = []; # Silently accept null argument for Matlab compatibility else error ('close: first argument must be "all", a figure handle, or a figure name'); endif if (strcmpi (arg2, "force")) delete (figs); return; endif else error ('close: second argument must be "hidden" or "force"'); endif ## Save and restore current figure cf = get (0, "currentfigure"); for hfig = figs(:).' set (0, "currentfigure", hfig); # make figure current __go_execute_callback__ (hfig, "closerequestfcn"); endfor if (isfigure (cf)) set (0, "currentfigure", cf); endif if (nargout > 0) retval = 1; endif endfunction %!test %! ## Test closing gcf %! hf = figure ("visible", "off"); %! unwind_protect %! close (); %! assert (! isfigure (hf)); %! unwind_protect_cleanup %! if (isfigure (hf)) %! delete (hf); %! endif %! end_unwind_protect %!test %! ## Test closing specified numeric figure handle %! hf = figure ("visible", "off"); %! unwind_protect %! close (hf); %! assert (! isfigure (hf)); %! unwind_protect_cleanup %! if (isfigure (hf)) %! delete (hf); %! endif %! end_unwind_protect %!test %! ## Test closing specified named figure handle %! hf = figure ("visible", "off", "name", "__foobar__"); %! unwind_protect %! close __foobar__; %! assert (! isfigure (hf)); %! unwind_protect_cleanup %! if (isfigure (hf)) %! delete (hf); %! endif %! end_unwind_protect %!test %! ## Test forcing the close of a figure %! hf = figure ("visible", "off", "closerequestfcn", []); %! unwind_protect %! close (hf); %! assert (isfigure (hf)); # figure not deleted %! close (hf, "force"); %! assert (! isfigure (hf)); # figure finally deleted %! unwind_protect_cleanup %! if (isfigure (hf)) %! delete (hf); %! endif %! end_unwind_protect ## Test input validation %!error <first argument must be "all", a figure handle> close ({"all"}) %!error <first argument must be "all", a figure handle> close (-1) %!error <second argument must be "hidden"> close all hid %!error <second argument must be "hidden"> close all for
