App designer app icon taskbar

Hi! I have made an app designer application and put a custom made icon for the figure. When I run the app by installing it on Windows OS, the app icon appears on top of the window but the icon of the app on the taskbar is that of MATLAB icon and is really annoying because it is very confussing. I have already searched the documentation and it doesnt give any information for this topic. I have MATLAB r2021a installed.

Same problem here.

Hi, I made an app a few months ago and did not have a problemwith this. At that time, the taskbar and window icons were both controlled by these:

1) UIfigure (from righ panel) --> identifiers --> icon

2) In compiler --> click on icon to the left of app title and upload

However, I made another app this week and noticed it was not working anymore. I contacted technical support and they said "The developers are aware of that issue and they might consider incorporating changes for this issue in the future. "

Hope this helps.

Having the same issue. After compilation, and even having icon set, after splash screen, matlab icon is showing on the taskbar.

Hi, the app reverts back to original Matlab icon when taskbar icons are grouped together by Windows. (In your Windows, go go settings, Taskbar, and choose "Always, hide labels" under "Combine taskbar buttons" option. You will see any custom app icon changes to original Matlab icon.).

Any solution guys?!

I don't think so you can change the icon in the taskbar beacuse in the end it is the matlab app designer application that is running the app that you made. Have to tried to host it as a standalone application?

Hello @Jordi Navarro,

I encountered a similar issue where the custom icon for the application was not displayed in the taskbar. Here are the steps that worked for me:

1. Access the “Component Browser” on the right side of the MATLAB App Designer interface.
2. Navigate to “app.UIFigure.” Within the “UI Figure” properties, under the “Identifiers” section, the “Icon” property can be set to the desired custom icon.
3. Deploy the application as a Standalone Desktop App.
4. Follow all necessary instructions to install the built application.
5. Upon launching the application, the custom icon should be visible on the taskbar.

For more details on deploying a standalone application, refer to the following documentation:

This issue might also occur when MATLAB applications are grouped together in the Windows taskbar, causing the custom app icon to revert to the default MATLAB icon. To prevent this from happening, refer to the following answer:
