Add source to setCellMeta

[sinnbeck]

Current it is possible to ensure the origin of most events by sending in a source parameter, which the can be extracted in the event handler. It seems that setCellMeta() and afterSetCellMeta() does not support this feature, but I think in some cases it would be nice to have, to easily detect where the change has come from (in cases where data is changed externally, like websockets or similar).

Hi @sinnbeck

Thank you for your input. I'll report your request internally for further discussion with the development team.

Hey @sinnbeck

Can you share a bit more details about what you'd like to achieve? Maybe a simple flag would do the job when there's no 'source' to be applied.

Here's an example https://jsfiddle.net/handsoncode/huvjb82y/

I'm using the flag to cut those changes that I want to be stored in a different way.

It is possible yes. But it is some extra state that would need to be managed. I am making a colab implementation of handsontable so changes can come from multiple people and from yourself.

But I did get a version working that just does not listen to afterSetCellMeta() at all and instead sends the changes directly in a websocket.

Mostly I just figured it would be a nice feature to have to make the API more in line with the rest of methods :)

Thanks for the update. In your case, it's better to have the ability to define a source. Gladly, you found a different way to make things work.
