see https://developer.gnome.org/glib/2.38/glib-Spawning-Processes.html#g-spawn-async-with-pipes 1. call g_spawn_async_with_pipes and get the stdin, stdout, stderr fds. 2. call g_child_watch on the pid returned in step 1. 3. create an io channel for each fd ( see g_io_channel_unix_new) 4. add each io channel to the main loop ( see g_io_add_watch) . read external application output (see g_io_channel_read_*) in the callback function GIOFunc and update your widget's text section 5. you can kill external programs by the pid you get in step 1. NOTE: you need to release fds in callbacks in step 2.
