Hi devs!
I'd like my python plugin to set an expression for overriding a property
and I have no clue how to do so. I expect there must be some generic way
to set expressions.
Specifically, I want to set the expression for the "Image source" of a
QgsLayoutItemPicture to:
'/path/to/pictures/' || attribute(@atlas_feature, 'ID') || '.svg'
Hope anyone can explain.
Thanks!
Raymond
