App Designer Compatibility between 2020a and previous versions of Matlab

4 visualizaciones (últimos 30 días)
If an App Designer App is created using 2020a and creates a context menu (available as of 2020a) on a list box. Will that context menu still be available and usable without producing an error if the same app is ran in 2019b? The documentation at https://www.mathworks.com/help/matlab/creating_guis/compatibility-between-different-releases-of-app-designer.html seems to suggest that the app should be able to run, but just won't be edittable. I am asking this because I can get access to 2020a on my laptop, but I only have access to 2019b with no way to get 2020a on my other work computer.

The app won't run in R2019b. You'll have to develop it on the earliest release that support is required for.

I would strongly encourage you make the business case to upgrade those computers if this app needs any longevity at all. GUIDE is going away. Any work you do now will need to be migrated or redone in the future if you use GUIDE.
You may also consider using R2020a and then packaging the app as a web app. Then any computer than can see the web server (internal or otherwise) could use it regardless of the installed version of MATLAB on that machine (they'd just use the app in a browser)..

The environment that I work in does not make it easy to upgrade to the newest versions of software. There are processes that must be followed and a lot of red tape. We were just able to get 2019b in January when the previous version we had available to us was 2016b. We have to be able to edit the program we are using on the fly, so packaging as a web app will not work. We will just have to wait until we can upgrade to a newer version which probably won't be for another 3-4 years.
