Is properties like global variables?

Hi! :)

Is properties in matlab app designer like global variables in matlab program? I am a little confused..

Answer 1

No, they are not like global variables. They are attached to the app object used by the callbacks and must be accessed similarly to structs:

app.property1=...
app.property2=...

[Walter Roberson]

Also the object class can be designed to restrict read or write access (though I am not sure how much support App Designer provides for this)

see the first line of a mlapp file

classdef app1 < matlab.apps.AppBase

Each AppDesigner app is nothing more than a class definition following the same rules.
