annotate examples/widgets/analogclock/AnalogClock.d @ 282:256ab6cb8e85
Signals look-up andNew syntax for connect. The old one will not work from now on. This will allow for the signals overload. Although changes are done for both D1 and D2 versions, D1 won't work because of compiler bugs. I am tired of waiting for fixes.
