Remove Event system #433

Description

@alexcjohnson

Companion issue to plotly/dash#531

Events are used only lightly in this repo. The changes I see to remove them completely:

  • Graph has events, and corresponding properties with the data, for things like click events, hover events... I don't see any need to use the events instead of just letting the property trigger the callback, but folks using the events would need to alter their code. Do we need to add timestamps for these, or is the existence of the data properties enough?

  • A bunch of components expose change events, fired with every character typed for example. The underlying value will also trigger a callback, I believe in all of these cases, so I don't think we're losing any functionality, but we may want to add timestamps - to all core components in fact - to help distinguish most-recent-user-input, for cases of multiple parallel ways to update the same output, as described in Remove Event system dash#531

  • Input already has n_blur[_timestamp] and n_submit[_timestamp] with no corresponding events. It doesn't even have a change event, but the note above ^^ still may apply to it.

  • Interval currently fires an event and increments n_interval - so we simply need to remove the event. No timestamp property is provided, would be an easy add if anyone was interested.

  • Textarea currently exposes blur and click events, which need to be updated to properties.

                              Remove Event system #433

                              Description

                              @alexcjohnson

                              Companion issue to plotly/dash#531

                              Events are used only lightly in this repo. The changes I see to remove them completely:

                              • Graph has events, and corresponding properties with the data, for things like click events, hover events... I don't see any need to use the events instead of just letting the property trigger the callback, but folks using the events would need to alter their code. Do we need to add timestamps for these, or is the existence of the data properties enough?

                              • A bunch of components expose change events, fired with every character typed for example. The underlying value will also trigger a callback, I believe in all of these cases, so I don't think we're losing any functionality, but we may want to add timestamps - to all core components in fact - to help distinguish most-recent-user-input, for cases of multiple parallel ways to update the same output, as described in Remove Event system dash#531

                              • Input already has n_blur[_timestamp] and n_submit[_timestamp] with no corresponding events. It doesn't even have a change event, but the note above ^^ still may apply to it.

                              • Interval currently fires an event and increments n_interval - so we simply need to remove the event. No timestamp property is provided, would be an easy add if anyone was interested.

                              • Textarea currently exposes blur and click events, which need to be updated to properties.
