in reply to alarms and timers on Win32

You could use Tk::After (doc) and give it a callback and time ... i am not sure if that will work on Win32, but i believe so. If you want to get really tricky, you could also use Win32::OLE or Win32::API to access the VB timer object, or other Win32 naitive function, directly. Lastly (and, i am sure this is not the last, but the last i have right now), you could fork a process to keep track of the time, and use IPC to update the label ... seems a bit complex for what you want though. Also, a pretty good clock inplimentation is here(analog), or maybe Tk::Clock ?

    Fine! Tk::After was what I was looking for. Thanks.

[Corion]: ambrus: Yeah, I read that, but it's somewhat vague as in what I really have to implement, and where/how my "other" mainloop should/needs to call AnyEvent
[Corion]: (or maybe I just work better from existing code that I munge until it works and I understand it rather than a short abstract text like "implement everything that's needed" ;) )
[ambrus]: Corion: I think in this case you can get away with only a stub for idle, one that always dies when you create it, because AnyEvent::HTTP doesn't use it, not even indirectly through AnyEvent::Handle or AnyEvent::Socket or AnyEvent::DNS.
[Corion]: The "and I understand it" part is optional.
[Corion]: ambrus: Yes but I also need to implement the file / IO watcher, because Prima has that (in Prima::File), and I need to supply the appropriate thing to make push_write etc. work with Prima
[ambrus]: Corion: yes, you need to implement the io watcher, which should be simple because Prima::File is basically that, and the timer watcher form Prima::Timer
[Corion]: ... or so I think. As I said, I'm somewhat vague on how to make AnyEvent cooperate with a callback-driven IO event loop that gives me callbacks when data is available or can be written
[ambrus]: what push_write thing? I don't think you need that. that's implemented generically by AnyEvent::Handle
[Corion]: ambrus: Yeah, that's what I think as well. But you give me an idea, maybe I should start with implementing the timer, as that should be far simpler and with fewer edge-cases/nasty interaction than the file watcher
[ambrus]: You only provide the watcher part that tells when the handle is readable or writable, not the actual writing and reading.
