Hi @klayoutmatthias,

awesome! Thanks for adding that!

I've noticed some issues.

Issue 1: Icons not drawn properly

Steps to reproduce:

• draw and select box on Metal3.drawing
• press 'Q' and open the layer list combo box
• NOTE: icons successfully drawn (that first time)
• cancel the dialog
• open again
• EXPECTED: icons again successfully drawn
• OBTAINED: icons appear mostly white

Issue 2: layer selection does not get applied

Steps to reproduce:

• draw and select box on Metal3.drawing
• press 'Q' and open the layer list combo box
• choose Metal4.drawing
• click OK
• EXPECTED: box now on Metal4.drawing
• OBTAINED: box still on Metal3.drawing

Also, I encountered the issue at some point that the combo box selection was not applied,
but rather re-set on Metal3.drawing

Very good. Thanks for testing!

Turns out there was some serious architectural rework needed (I told you it's not easy). I uploaded new commits. If you find the time, please give it some test. For me it works well now.

Best regards,

Matthias

Thanks for the fix! Just tested,

1. layer switching works now
2. the icon drawing problem is still the same

Beim ersten Öffnen sind alle Icons kaputt, außer dem des effektiven Layers:

Wählt man was andres aus, oder öffnet den Dialog erneut wie vorher, dann sind die Icons wieder alle dahin:

Danke für das Testen. Das sieht dann eher nach einem Problem mit der Speicherverwaltung aus. Das Icon neben den Objekten im Baum links ist aber immer in Ordnung. Korrekt?

@klayoutmatthias ja, links im Baum stimmen die Icons, auch bei ~500 Elementen in der Selektion

I can't reproduce the problem when not using a technology.
With or without -l my.lyp, klayout shows the icons in the drop down menu for me the first time around.
self-compiled M1 Tahoe qt5

I just noticed we switched to German / Austrian :)

I pushed a commit which I hope fixes the problem now. There was a place where the image for the icon wasn't copied by Qt. So basically the image is free'd memory. That would explain, why it can be reproduced occasionally only.

Thanks for testing! :)

Now it works:

Before I still had the issue (even rebuilt from scratch, which I retested after @stefanottili comment).
