Tk::MainWindow->new() XLib error

gri6507 has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

I have a Tk GUI that could be running on one Solaris machine and display on another. Of course, everything works when the displaying machine has added the running machine's info to its xhost list. But let's say that this is not the case. In other words, the running machine is not allowed to display on the displaying machine. Then, you get the follwing error:

Xlib: connection to "displayingMachine:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
couldn't connect to display "displayingMachine:0.0" at /usr/local/Acti
+vePerl-5.6/lib/site_perl/5.6.1/sun4-solaris-thread-multi/Tk/MainWindo
+w.pm line 55, <STDIN> line 1.
MainWindow->new(-title,CalTool,-width,500) at cal.pl line 860

Of course, the first two messages are coming from the XLib and are important. However, I would really like to NOT display the other two messages, yet there seems to be no documentation on how to do that. Does anyone have any ideas? Thanks.

Have you tried putting 'eval' around your script? `eval { require Tk ; MainWindow->new() ; MainLoop ; } ;` [download]	[reply] [d/l]
