Hi,
When constructing a custom UI component whose class inherits an App-Designer-Components class, the constructed component doesn't show up.
I can't figure out why, any ideas?
Or maybe, App-Designer-Components class were initilally thought to be sealed?
Thank you very much! ;)

test script:
hf = uifigure();
hb = UIButtonSubClass('Parent', hf);
custom class:
classdef UIButtonSubClass < matlab.ui.control.Button
properties
additionalProperty
end
methods
function this = UIButtonSubClass(varargin)
% constructor
this = this@matlab.ui.control.Button(varargin{:});
this.additionalProperty = 'something';
end
end
end

Looking to my test, MATLAB does not accept that a uifigure has a non-native MATLAB class as a children. So unfortunately, it's not possible to do what you want.
However, as alternative solution, you can freely use the property UserData of any MATLAB graphical class.
