Feature request #18681
[Processing] Allow "select by ..." algorithms to work with selected features
|Pull Request or Patch supplied:||No||Resolution:||wontfix|
|Easy fix?:||No||Copied to github as #:||26569|
The "select by attribute", "select by expression" "select by location" (and maybe their random friends, but i'm not sure whether this is desired) do not have the "selected features only" checkbox.
Use case: i want to select features where "fieldA"='xx' and "fieldB"='ff' but I'm beginner (or occasional user) and don't know how to use expression so i'll use "select by attribute" algorithm. Issue is that i can select fieldA='xx' features but it's all. I can't run the second request on selected features, it runs on whole layer.

I'd say that they are workarounds but not in all cases.
For example with this feature, I can do a selection with the "select by rectangle" tool (hence no obvious spatial or attribute logic) and refine/adapt the selection using the algorithms and #18682 parameters. I don't think that #18682 only is enough for this experience.
Then the idea is also, for consistency, to have the same logic and the "selected features only" checkbox present in most (or all other) of the Processing algorithms dialog.
