Check if New Desktop addon is used in current session

Is there a way to check programmatically if in the New Desktop is active in the current session (I want to detect this info in a startup file)?

@Marco Pasquali, may I ask out of curriousity how you would use the information about whether MATLAB is running in the new desktop? What would your startup file do differently for the new desktop?

At first I wanted to execute the line that disable the "Show Code" panel in th new figure UI only when the new desktop is used (probably executing with the "old" desktop it's not a problem, but who knows). But then I discovered an important bug (for me) in the new desktop, and I was thinking if it was possible to write a simple workaround when the new UI is used.

Just for info, the issue in question is that with the new desktop the warning that prevent closing the main window, asking for confirmation, is not active even if selected in the options (I've already send a feedback to the team).

Thanks for the description, @Marco Pasquali. Thanks for sending the feedback!

Just checking on this one, do we have a way to identify the desktop type programmatically?

[Adam Danz]

@sst, short answer is no but it would be helpful to know how you would use that information. There may be a workaround or another way to identify what you're looking for.

In my specific case, I would like to use unicode characters for the "listbox" uicontrol, which works only in the New Desktop mode, and not in the classic desktop mode. The classic desktop mode, on the other hand, allows the use of HTML content in the uicontrol, but not unicode characters. This is part of a much larger application.

Thanks for this info @sst.

Hi @Marco Pasquali,

To confirm programmatically whether the new MATLAB desktop add-on is active in the current session, you can use the rendererinfo command. Specifically, check the GraphicsRenderer field by running the following command:

rendererinfo().GraphicsRenderer

If the output is 'WebGL', it indicates that the session is utilizing the new desktop add-on.

For more details about the rendererinfo command, you can refer to the MATLAB documentation::

Thanks, that looks like it's working.
