As outlined in #3557 this PR adds a
output_updated.OutputArea
event, triggered byupdate_display_data
messages, to match the existingoutput_added.OutputArea
event which is triggered whenexecute_result
anddisplay_data
messages are received. Like theoutput_added
event this allows registering callbacks which are given the entire mime bundle and the OutputArea, matching the capability of JupyterLab MIME renderers which are also given the entire mime bundle whenupdate_display_data
messages are received.Let me know if there is some place to document this new event and/or add some kind of test for it (couldn't find either in a cursory search). As an aside, very happy about my first ever contribution to the notebook.
