Why can't I see the component library when I open my app designer?

Hi,

The problem lies in persisting the panel layouts.

The UIContainer framework saves the side panel layout information in a JSON file, which may have become corrupted on the machine.

To resolve the issue, please follow the steps listed below:

1. Locate the "AppDesignerMainPanelLayout.json" file. The path to the file should be similar to the following:C:\Users\<User Account Name>\AppData\Roaming\MathWorks\MATLAB\Release\
2. Delete the "AppDesignerMainPanelLayout.json" file.
3. Restart MATLAB.
4. Launch MATLAB App Designer.

I cant find “AppDesignerMainPanelLayout.json”,but I deleted all the json files. It's still not working.

[Ayush Singh]

Can you let me know which location did you try finding the json files?

Also share the screenshot of the entire screen, end to end.

Problem solved, thank you very much!

Hi

Look at the 2 images I have attached:

On "app_designer1.png" I added an arrow pointing to the edge of "Components LIbrary" Strip

When I hover next to it - there is a "scroll anchor" that enables to enarge/fold this region

See app_designer2.png for how it looks after minimizing

Try to look for this "anchore" to the left of your appdesdigner GUI and then - enlarge it (click and drag the "Components Library" strip to the right)

I can find this "anchore",but it's for dragging 'tab' options, not component libraries
