Understood, linking your rephrased thread here, seems related.
I do not have a ready solution but you can have a look at this:
Once you have screen size of the object, you can compare it to the designated screen location and determine whether the two overlap. You will need to do a bit of reverse engineering here.
There might be an easier, more obvious way but I’m not aware of any ready-to-go solutions available for something like this.
Perhaps you could briefly describe what it’s going to be used for. It may shed some extra light on how things are supposed to work.
