Appdesigner does not admit editing of the classdef line.

¿Is there a built-in or otherwise recommended method for converting between ComponentContainer- and AppBase-derived classes?

E.g., ¿could this be done by exporting to .m file, editing, and then somehow importing as .mlapp?

One workaround for the component→app direction, is to wrap the component in a trivial application.

Hi,

You can export the App Designer project as a MATLAB file (.m) and edit the classdef line in the exported file. Once you've made the necessary changes, you can import the updated MATLAB file back into App Designer using the "Import" button on the "Apps" tab.

Alternatively, you can create a new App Designer project based on the ComponentContainer or AppBase class, and then copy and paste the relevant code from the old project into the new one.

Thanks for the quick reply, Harsh.

I'm stumped by this bit:

"... you can import the updated MATLAB file back into App Designer using the "Import" button on the "Apps" tab".

I can't seem to find an "Apps" tab in in AppDesigner, nor an import button under the Apps tab in the primary MATLAB editor, or elsewhere for that matter.

Every chance this is some form of selective blindness.

I'm using 2022b, but I do note a search prior to posting the above question, yielded the following adivce from 2020:

"Currently, there is no option to import .m file ... into app designer"

And this from 2021:

"There is no easy way to import the exported "m" file into AppDesigner"

Cheers
