If we want to have such fine-grained change propagation with a NewValueHolder for each widgetproperty, we need a much more lightweight announcement proces. NewValueHolder initializes a boolean lock and an Announcer. The announcer initializes a SubscriptionRegistry. The subscriptionregistry initializes a Semaphore and an IdentitySet. An identityset initializes with a tally and a size of 5. If we know most valueholders never need to propagate a change, and most of the others only to one subscriber, we should introduce some null/one objects. Alternatively, we could propagate change at the widget level instead of the property. Stephan

Where would you like to define application style default overrides then? People ask about this all the time, and the reason it's used so little is because our implementation in the widgets is so bad: very inconsistent naming and default styles ignoring overridden values Stephan

Also maybe let's not push behavior changes two days before releaseâ¦ one of the proposed changes to not fire announcement when the object has changed would actually break thingsâ¦ changes need some time to trigger all the bugs. :) After all the smallest changes usually have the highest bugrate, because when you go fast it's easy to not realize / forget corner cases.

Mooc bugs

by stepharo

When I type foo "bar" in the editing pain of the System Browser, and then delete the second '"' I get the same error as the OP. When I try to exit the System Browser a debugger oppens up with a "Subscript out of bounds" and then the system locks up. I was on 32 bit Windows 7 when this happened. Stef
