gtk labels

'm in the process of making a frontend for one of my programs. I want
to use a label to print updates to the user. When environmental
variables change, I alert the user, but I use g_print and output it to
the command line. I want to know how to print this output to a label
instead.

I've heard that one way of doing it is by using gtk_label_set_text(),
but I'm unsure how to direct the output of g_print to the label.

A short example would be great.

Thanks.

g_print isn't what you should be using, although you could hack it using
g_set_print_handler:

http://www.gtk.org/api/2.6/glib/gli...ns.html#g-print
http://www.gtk.org/api/2.6/glib/gli...t-print-handler

....the best thing to do is start using g_strdup_printf:

http://www.gtk.org/api/2.6/glib/gli...g-strdup-printf

....and then either setting the output to a label or the console.
