stdout/sterr to GtkTextView at runtime

[orangensaftx web de]

Hi,

 

I'm writing a gui for an existing program that can run for a while. I want to display all possible terminal output of this program in a GtkTextView. So far i failed to display the output at runtime. I tried this

 

my $iter = $textbuffer->get_end_iter;

my $command = `perl test_output.pl 2>&1`;

$textbuffer->insert($iter, $command);

 

which isn't working the way i want. My program is blocked while test_output.pl is running. I tried to use

 

my $command = system("perl test_output.pl 2>&1 &");

 

instead but while my program keeps running, all output is shown in the terminal again.

 

 

How can i achieve to get all output at runtime in my textview? And how do i check if test_output is done running? I found an old solution using Gtk+ itself but my perl skills aren't good enough to reproduce this:

I'm using Gtk3.

 

 

Thanks for any help.
