[Octave-bug-tracker] [bug #43282] annotation function missing

[Pantxo Diribarne]

Follow-up Comment #18, bug #43282 (project octave):

Hi,

I performed the following tests in Matlab 2013a:


clf;
ca1 = axes ();
ch = allchild (gcf ());
pos = find (ch == ca1);
h = annotation ('rectangle'); # Annotation drawn on top of the first axes
hover = get (h, 'parent');
ch = allchild (gcf ());
pos = [find(ch == ca1) find(ch == hover)] #-> [2 1]
ca2 = axes (); # Second axes drawn below the annotation
ch = allchild (gcf ());
pos = [find(ch == ca1) find(ch == hover) find(ch == ca2)] # ->[3 1 2] 
axes (ca1); # First axes now covers the annotation
ch = allchild (gcf ());
pos = [find(ch == ca1) find(ch == hover) find(ch == ca2)] # ->[1 2 3] 
set (ca2, 'handlevisibility', 'off');
axes (ca2); # Second axes now covers the annotation
ch = allchild (gcf ());
pos = [find(ch == ca1) find(ch == hover) find(ch == ca2)] # ->[2 3 1] 
h = annotation ('rectangle'); # Annotations are back on top
ch = allchild (gcf ()); 
pos = [find(ch == ca1) find(ch == hover) find(ch == ca2)] # ->[3 1 2]


So my previous modifications of axes.m are not quite right ... the call form
"axes (HAX)" restacks the figure children so that the annotation axes may be
covered. This call form also restacks axes with "handlevisibility" == "off".
I attached a changeset that makes Octave behave as Matlab in all the above
situations.
