[Octave-bug-tracker] [bug #31468] multi-line text objects

[Ben Abbott]

Follow-up Comment #34, bug #31468 (project octave):

I ran some additional tests for the text() command. ML's text() command only
accepts string and cellstr arguments. However, the string property for the
text object can be set using numeric values.


figure (1)
clf
text (0.5, 0.2, 'char')
text (0.5, 0.4, ['char row 1'; 'char row 2'])
text (0.5, 0.6, {'cell2str (1,1)', 'cell2str (1,2)'; 'cell2str (2,1)',
'cell2str (2,2)'})
text (0.5, 0.8, 1:10)
 
??? Error using ==> text
String argument expected after 2 or 3 numeric arguments
 
h = text (0.5, 0.8, 'tmp');
set (h, 'string', 1:3)
string = get (h, 'string')
class (string)

string =

1
2
3

ans = char


I can modify the changeset to be compatible in most cases. The one thing I
don't know how to do is change set(h,'string', 1:3) so that the result is
stored as num2str((1:3)(:)).

For those who are interested, I've attached a pdf (test_text.pdf) illustrating
the result of the ML commands above.
