I need a QgsMapLayerComboBox to show only layers whose name contains a specific word. I have no way to know the names or geometry of the layers beforehand - I can only filter them based on whether or not they contain this word.

I thought about using setFilters(), but it looks like it only allows to filter by geometry or layer type, not by layer name. I also read about setExceptedLayerList() - but as I mentionned earlier, I don't know the exact name of the layers I don't want to show in the QgsMapLayerComboBox.

So, is there a way for me to use setExceptedLayerList() with an expression referring to layers whose name does not contain the word I need? Or another method that would allow me to filter the layers in my QgsMapLayerComboBox based on a word in their names?

You could use the following logic which excludes the layers not containing the name you define:

name = 'someName'
layer_list = []

for layer in QgsMapLayerRegistry.instance().mapLayers().values():
    if name not in layer.name().lower():


If you want it to be case-sensitive, remove the .lower() method.
