How to programmatically get a list of all app properties in AppDesigner

Hi,

I'm writing a large app in appDesigner, and I want to create a list / text area that would display all of the app property fields. I can't find a way to programatically pull their names, does anyone know a way of doing this?

P.S. I'm on 2022b.

Thanks!

you can get all public properties with :

P = properties(app);

for all private and public properties you can use meta class properties function:

mc = ?appname

use the application name for appname (the name you saved .mlapp file, or name that appears after classdef at first line).

after that call for property list:

P = mc.PropertyList;

it give you a property array with the size of number of properties. and for eachone their information. for example run :

P(1)

or

P(1).Name

( i think the first index always is UIFigure)

a simple example for listing the names:

for i=1:numel(P)
Name{i} = P(i).Name;
end

Thank you, the second method works great! I only neede the private properties, I was able to get the public ones on my own but not the private ones. I used the following to get and list in a ListBox only private, following your code suggestion:

mc = ?MyApp;
P = mc.PropertyList;
ii = 1;
for n = 1:numel(P)
    if strcmp(P(n).GetAccess,'private')
        Items{ii} = P(n).Name;
        ii = ii+1;
    end
end
app.ListofpropertiesListBox.Items = Items;

To identify the properties that are created for just the GUI I used the P.Validation.Class.Name.

name = 'appFileName';

mc = eval(['?', name]);

P = mc.PropertyList;

np = length(P);

flt = false(np,1);

for n = 1:np

flt(n) = contians({P.Validation.Class.Name}, 'matlab.ui');

end

The Auto generated Properties have validation that start with 'matlab.ui'.

I use the filter to remove the auto generated properties.

P_used = P(~flt);
