[Octave-bug-tracker] [bug #53468] Octave 4.3.0+ can't load figures saved with previous versions

[Guillaume]

Follow-up Comment #12, bug #53468 (project octave):

I agree that the test cases from the patch should be added to stable.

My comment was just that the patch also makes a small change to struct2hdl - I
am actually happy with it and think it is a good strategy to create the figure
invisible first, populate its content and make it visible at the end if
required (it might actually be faster and will prevent a figure to appear
temporarily if it was meant to be invisible at the end of the day anyway). As
long as the input structure to struct2hdl always defines the "Visible"
property then things will behave in the same way. It would affect the
following code though:


s_oct40 = [];
s_oct40.handle = 1;
s_oct40.type = "figure";
s_oct40.properties.tag = "";
s_oct40.children = [];
s_oct40.special = [];

get (struct2hdl (s_oct40), "Visible")


But it is not an issue if the input to struct2hdl is always coming from
hdl2struct/hgload where all of the properties are always present.
