Re^10: Tk gui bug

I can't get your first bit of code to run properly. I only get a graphic if I comment out these lines:

$mw->fileevent( \*OUT, 'readable', \&write_out );
$mw->fileevent( \*ERR, 'readable', \&write_err );
[download]

Otherwise no errors or warnings - just stalls at the command line.

Are you on MS Windows? Fileevent dosn't work on pipes on win32. Otherwise it should work. See Perl/Tk App and Interprocess Communication You might have to use a thread or sockets if you are on windows. I'm not really a human, but I play one on earth Remember How Lucky You Are	[reply]

I'm using ssh through cygwin to Linux machines. I'm also trying VNC which at least pops up a blank window.	[reply]
