Passing data between UIFigures

Hi. I'm building a program by app designer that has 3 different window. My quesiton is, how I can share data and variables between them?

Since AppDesigner is based on classes it is very easy to just set data from one in another, but you haven't given any details of how you create your windows so a generic answer is far too vague and time-consuming.

Answer 1

app2.R = R;

would work if you just want R, you don't need app1, but equally:

app2.field3 = app.field3;

for example would also work, though you should name properties as descriptively as possible.

Obviously whatever you choose you must define the property in app2.

How can I change the class name of the second UIFigure? The names of the second UIFigure and *.mlapp can be renamed, e.g. 'app2', but the class name is also 'app', the same as the first one, and can not be changed. All properties in the second UIFigure are alsso called as 'app.*', e.g. 'app.R'.

Within a given UI class in App Designer the object itself is usually referred to as app, but in a your own function you can call it whatever you want and when you create your two GUIs you will give them each your own name that is used external to the object.

e.g.

myApp1 = App1( );
myOtherApp = App2( );

myApp1.someProperty = someValue;
myOtherApp.someOtherProperty = someOtherValue;

Thank you! I got it.

Let say that in first class (app1), I have a piece of code for Run button callback:

function RunButtonPushed(app, event)
          V = app.field1.Value;
          p = app.field2.Value;
          R = V*p;
          app.field3.Value = R;

          %open the second window
          app2;
 end

Then in second class (app2), after pressing the Solve button, I'm going to the value of R (from the first window). Now what is the content to be used for retrieving it from app1 classdef.
