Bug 267913 was fixed in order to allow TextViewer in jface.text to group a sequence of VerifyEvents that belong to one logical modification (key press) in the widget. While this works, it requires TextViewer to run its own editing story, as it currently vetoes any VerifyEvents and then modifies the text content itself. This is necessary because there is no way to detect the last event of a sequence if it relies on the event timestamp. It would be much easier for jface.text if the events shared a tag that would let TextViewer know that 1) an event is part of an event sequence 2) an event is the first or last event of the sequence For example, the event could state the total number of events in the current sequence (1 for the trivial case), and the rank of the event in the sequence. Perhaps some of the many fields of VerifyEvent could be re-used for that purpose?
Do you need that information only during Verify ? I guess we could use Event#index and Event#count to indicate for that. Steve ?
(In reply to comment #1) > Do you need that information only during Verify ? Hm, it would be enough to have it on Verify to tackle the problem we solved using the event time - however, from an API perspective, it would probably make sense to have the same information on other batched events, notably Modify.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
