hObject is not created when running GUIDE *.m file - what can be done?

Hello,

please see snap shot below:

I'm using MATLAB 2013b.

It's works perfectly fine in MATLAB 2015 and above.

What could be the cause of this? I need to compile my GUI in MATLAB 2013, but for some reason it doesn't want to "create" any hObject & handles objects...

What can be done?

THANKS !!!

Can you attach your m file ?

In your screenshot it look like hObject is created just fine. What is you question?

[Mark Golberg]

this is how it looks in MATLAB 2015. You can see hObject is 1x1 Figure, and NOT a single value int.

[Rik]

I don't see the issue. At some point the handle to objects was no longer exposed to the user, but treated as an object. None of the syntax became incompatible because of that.

f=figure(1);set(f,'Visible','off')
set(f,'UserData','foo')
disp(get(1,'UserData'))

foo

class(f)

ans = 'matlab.ui.Figure'

There are many reasons to avoid GUIDE, but this specific 'issue' is not one of them.

The m-files created by GUIDE are not compatible with other Matlab versions You can expect such troubles.

Just to add my two cents:

For general advice and examples for how to create a GUI (and avoid using GUIDE), have look at this thread.

Thank you Jan, that was it.

BTW, strangely enough, m-file that was created by GUIDE in MATLAB 2020, opened in MATLAB 2017 quite fine...

@Rik

Thanks. Unfortunately it's a legacy APP with thousands of code lines... not so simple to switch to APP Designer at the moment...

AppDesigner is only one other option, but I understand your problem.
