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;
