spectral library memory vector layer not selectable in QgsProcessingMapLayerComboBox

[Andreas Janz]

After creating a library…

‌

… I can’t select the library in a QgsProcessingMapLayerComboBox widget, e.g. for using the library as training dataset:

‌

‌

How to reproduce.

1. Create a new library:

   

2. Try to select the library in any QgsProcessingMapLayerComboBox that allows vector layers.

Which QGIS do you use and how did you start the Create Classification dialog?

[Andreas Janz]

QGIS 3.24

‌

[Andreas Janz]

how did you start the Create Classification dialog?

It’s a general problem, you can use any QgsProcessingMapLayerComboBox widget.

[Benjamin Jakimow]

Again, which QGIS version do you use and how did you start the dialog?

[Andreas Janz]

Already answered both questions

Ah yes, I just saw the screenshot.

Now you can select speclibs with/without geometries and file/memory based.
But it seems that there is an additional filter that prevents these speclibs to be set after selecting them in the combobox

You are using the deprecated Classic version. Here you need to also specify a renderer before the layer will be accepted.

We haven’t yet decided, if Classic will be removed for v3.10.
