[wxperl-users] wxWindows & sleep bug

[Graciliano M. P. \(V. Sites\) <gm...@vi...>]

Mattia,

  Maybe I found a bug with wxWindows and sleep. see if you can duplicate it.

  If you make a Show(1) to a frame, the first sleep() after the show are
ignored by perl!

  I was looking about sleep in the pod and I saw that if perl receive a
SIGALRM it go out of a sleep. Maybe wxWindows create a SIGALRM and this make
confusions. You can't use sleep() with alarm() too, because in some OS (like
Win32) sleep() was internally implemented with alarm().

  I don't know if this erro exist in other functions, like Show(). To fix
this in my App I put this code after the Show:

       for(0...3) {sleep(0)} # Sometimes need more than one to fix.

  I only saw the bug in Perl 5.8 Win32. I haven't Perl 5.6.1 for Win32 any
more to test...
