Re: [reactive] Re: reactive (-glut) problems?

I had experienced large delays at the first rendering of some shapes, that were attributed to tessellation. Perhaps the delays result from that? Are you displaying any shapes for the first time? Eyal 2008/12/3 Balazs Komuves

It seems that the function 'justE' caused my problem. If I remove that, replacing the section at issue with

exitE = fmap esc ky where

...

esc k = case k of Char '\ESC' -> exitSuccess _ -> nop

then the program works. However, there is a large random delay, sometimes measured in seconds, before processing the events in the second argument of `mappend`. And it still leaks space. Any advice? (all this is with reactive-0.9.6 and ghc 6.10.1)

Dear All,

I'm trying to get my hands wet with the reactive library, but already the simplest example I cooked up is failing to work properly (and leaks memory, and uses relatively lots of cpu time).

The problem appears when I try to merge my two events with `mappend`. One event should exit on pressing ESC, the other draws colored circles on pressing the left mouse button. They work correctly separately.

Could somebody explain me what's happening, or whether I'm making a basic mistake?

The code is below, I hope the formatting survives the various email systems. I don't know if that matters or not, but I'm using OS X.

Thanks, Balazs
