DESIRED BEHAVIOUR

If you create:

h = uicontrol('style','edit');

Then if you type

h.<tab>

and then select 'HorizontalAlignment', you can again < tab > to get a list of alignment options.

Alternatively, with

set(h, 'HorizontalAlignment', ' <tab> ...

ATTEMPT TO REPRODUCE IT

I am wondering if there is a way to take advantage of this behaviour for user defined classes of the type hgsetget

I tried

classdef foo < hgsetget
    properties
        HorizontalAlignment
    end
end

Then in a separate folder, i.e. .\+foo\, I created and enumerator

classdef HorizontalAlignment 
    enumeration
        left   
        center 
        right  
    end
end

but to no avail.

I tried several things, like defining a set.HorizontalAlignment(obj,val) mnethod which then calls the foo.HorizontalAlignment class, still no way to get the autocomplete.

Anybody has hints?

I've been fiddling around and by mistake I found that the matlab.system.StringSet class of the matlab.System package allows exactly the < TAB > complete behaviour.

Note : the doc links are under symulink, however the package is under:

fullfile(matlabroot, 'toolbox\matlab\system')

and therefore, does not require Symulink to be installed.

A barebone example :

classdef foo < matlab.System
    properties
        Coordinates
    end
    properties(Hidden,Transient)
        CoordinatesSet = matlab.system.StringSet({'north','south','east','west'});
    end
end

usage :

obj = foo
obj = 
  System: foo
    Properties:
      Coordinates: []
set(obj,'Coordinates','<TAB>

More details can be found on Limit property values to a finite set of strings

Nice one, Oleg.

I added your discovery to my recent post on class property tab-completion .

Note that this only works for classes derived from matlab.System.
