Hi, Really odd, you should see the button....i use linux.

So somewhere in my GUI script i call another script in a subfunction, and it's looking like that:

my $name = $ent -> get();
my $log = qx(perl /xx/bgt/structure.pl $path_dir $name);

The problem is that in my $log variable i can't store the output of the script. Do you know an alternative to call a script and store the output into a variable? Thank's. Both of my variables that are used in the script call are defined, the call of the script is good, just that i can;t store the output into a variable

The reason the button is missing is the odd $mw size he has, in addition to the bizzare padding values. :-) Take out the geometry line and you may see it.

nope -- it gets wider but the button still not visible

Well, that uses the shell, but should work if everythings properly quoted ... inside of tk and outside of tk ... if it isn't working ddumper up the value and examine it (a technique detailed in Basic debugging checklist and brian's Guide to Solving Any Perl Problem )

Alternatives are Capture::Tiny, IPC::Run3, String::ShellQuote , Win32::ShellQuote, Proc::Background, system_detached (yes, the links are copy/paste I dont like editing too much:D)
