How to indicate if the program is processing in app designer?

My program sometimes takes 10-20 seconds to run. The problem is that I don't have any way to see if the program is processing or it just hit a bug.

Is there a way in app designer to let the user know that the program is running after the they've pushed the button?

function CalculateButtonPushed(app, event)
            
            
            x=app.XEditField.Value;
            y=app.YEditField.Value;
            z=app.ZEditField.Value;
            I=app.CurrentAEditField.Value;
            
            
            
            [Bx,By,Bz] = Magnetic_field_solenoid_cartesian1(app,x,y,z,I);
            
            app.BxmGsEditField.Value=Bx;
            app.BymGsEditField.Value=By;
            app.BzmGsEditField.Value=Bz;
end

Put some text on the GUI? I created a BusyCursor class that I use in regular figure and GUIDE apps. No idea if it works with AppDesigner as I haven't tried, but essentially all it does is change the cursor to the Windows busy cursor.

In other situations I use a progress bar (one from the File Exchange, but the builtin waitbar works too).

and in other cases I simply put a small place on my GUI for info text and change it to 'Processing...' and then to 'Done' or something similar once processing completes.

Use the function dlg = uiprogressdlg(app.UIFigure); See documentation for all available options with the function.

This doesn't really suit my need. I don't want a "progress bar". I just need an indicator with two states: "calculating" and "done" and preferably it's implemented in the GUI instead of a pop up screen.

Just implement it then! What is causing the problem?

            function CalculateButtonPushed(app, event)          
            % app.ProcessIndicator is a text area
            app.ProcessIndicator.Value='Processing...';
            x=app.XEditField.Value;
            y=app.YEditField.Value;
            z=app.ZEditField.Value;
            I=app.CurrentAEditField.Value;
            
            
          
            [Bx,By,Bz] = Magnetic_field_solenoid_cartesian1(app,x,y,z,I);
            
            app.BxmGsEditField.Value=Bx;
            app.BymGsEditField.Value=By;
            app.BzmGsEditField.Value=Bz;
            
            Bt=sqrt(Bx^2+By^2+Bz^2);
            app.BtotalmGsEditField.Value=Bt;
            
            app.ProcessIndicator.Value='Done!';
            end

I tried this but it only shows the "Done!".

Try putting a

drawnow

or

pause( 0.1 )

instruction after

app.ProcessIndicator.Value='Processing...';

Worked flawlessly!! Thanks.
