Flagging own question as duplicate or deleting it?

Question

I recently asked the question How to get signal when toggling a group? where @FranciscoRaga kindly referred me to another post which provided an answer.

Should I mark my question as a duplicate or delete it?

Answer 1

I think you should vote to close it as a duplicate which I think should take effect immediately.

That way it becomes another signpost to the same answer.

Answer 2

Perhaps there was a reason you did not find the other question.

So, besides what @PolyGeo answered, I suggest always try editing the duplicate question for readability and searchability (title, body and tags) if one thinks it is appropriate.

For example, usually titles starting with:

• In QGIS plugin, ... or
• How do I ...

are not the best for distinguishing content through searching.

Here is a Meta SE Q/A with hints for writing titles: How do I write a good title?*
