Do we have a comparable API on anything else?

Searching the docs for cursor_data suggests we don't.

Do we want to make this a general Artist API, and set as appropriate for different artists (like set_snap, set_in_layout, etc)?

This sounds like a good idea, but maybe not for a bugfix release.

I agree the slowness isn't really acceptable. No strong opinion as to the exact control API (well, perhaps a vague preference for a setter/getter for API consistency, but heh). |
Do we have any general policy or preference for attribute vs. property vs. getter/setter? I'm also open to any, but attribute was the fewest lines of code to implement |
|
I don't know policy-wise, but the statu quo would certainly be a setter. |

PR Summary
For moderately sized QuadMeshes getting the cursor data is very slow - see #21917 (comment). As such, disable by default for now, but allow users to manually enable it.
Fixes #22253
