We created Piemenu with this code.
At first it worked without any problems, but when I opened it today, the icon was not displayed.

I checked the value of icon_value using this method that you taught me in my previous post.

But now the icon_value value is not printed out to the console by the print function, but instead I get the following error
[ERROR (bke.icons): C:\b\buildbot-worker-windows\windows_291\blender.git\source\blender\blenkernel\intern\icons.c:743 BKE_icon_get: no icon for icon ID: 993]

I have searched and searched for errors, but could not find the cause of this symptom.
Please let me know if there are any possible causes for this symptom.

You can’t use hard-coded values, they are different every time, depending on the order of loading icons. The “icon_value” is returned by the function that loads the icon, e.g. “_icon_value_from_icon_handle”.

Thank you very much.
That’s the first time I’ve heard of it.

icon_value = space_toolsystem_common.ToolSelectPanelHelper(). _icon_value_from_icon_handle(“ops.transform.edge_slide”)

↑ By changing to this way of writing, the icon is now displayed without any problem.

Very realy thank you.
