Michael: Did you ever respond to this message (30 October 2023, pretty fresh)?
Something weird is going on - I can't find this message in the archive, but several people did respond to it, but not you (or maybe your response went to the same /dev/null as my original post). -andy From: Andy Goryachev <andy.goryac...@oracle.com> Date: Monday, October 30, 2023 at 12:53 To: Michael Strauß <michaelstr...@gmail.com>, openjfx-dev <openjfx-dev@openjdk.org> Subject: Re: Prioritized event handlers Dear Michael: Thank you, this is very helpful. Questions/Comments: 1. Does this proposal changes the way events are dispatched with respect to priority? In other words, does it first go through the list of all handlers registred on the leaf Node (high priority first, then lower, then lowest), then bubble up? Or do they propagate upwards looking for high priority handlers first, then the process restarts for lower priorities, as I saw in some previous emails? (I could be mistaken) 2. Do you propose to abort event dispatching immediately after the event is consumed? This probably should be mentioned earlier in the Motivation (the problem statement) section. 3. I wonder if three priority levels are sufficient. Let me explain. We have two possible actors who can register an event listener: the application code and the FX (or, rather more specifically, the skin and its behavior, whatever that might be). Application code might want to add handlers at three possible priorities: * App handler must always be called before any fx handler * App hander does not care * App handler must always be called after any fx handlers For fx/skin handlers we might have fewer levels: * Skin handler does not care * Skin handler must be called after all other skin handlers This situation maps to 5 priorities and 4 effective levels (or 5). We should also mention the fact that when any actor adds two or more handlers for the same event with the same priority, they get invoked in the order added. Would you agree, or am I missing some critical aspect of the proposed solution?
