[Octave-bug-tracker] [bug #39483] axes "handlevisibility" not properly handled with new children objects

[Pantxo Diribarne]

Follow-up Comment #2, bug #39483 (project octave):

In the example below "ax" handle is not visible and not the current axes as
expected :


fig = figure (2345); clf
ax = axes ('parent', fig, 'handlevisibility', 'off');
get (gcf, "currentaxes")


Then, when "gca ()" is called in line.m (also text.m, image.m ...) a new axes
is created. 

Most plot functions (not line, but it probably could) use
__plt_get_axis_arg__.m to parse input arguments and retrieve parent axes. The
attached patch adds a search for "parent" property in __plt_get_axis_arg__.m.
If present the prop/val pair is removed and the righ parent axes is returned.
It works for hggroup where no call to "gca ()" is done:


fig = figure (2345); clf
ax = axes ('parent', fig, 'handlevisibility', 'off');
hg = hggroup ('parent', ax);
disp (sprintf ('Figure children list should be empty, result: '))
disp (get (fig, 'children'))

returns the empty matrix as expected. I think using this patch and replacing
the calls to "gca ()" by "get (fig, "currentaxes")" in the various line,
text... functions should work. Should I go ahead ?
