[Glade-users] how to update process_bar in real time between multi-processes?

[Tristan Van Berkom]

By child process you mean a result of fork() correct ?

if its really a child process, then that process will have to write its progress
to a file descriptor (probably a named pipe) and you'll read it in an iochannel
and update the progress bars from there.

if they are threads then you can just use g_idle_add() to tell the main GUI
thread to update the progress bars.

Cheers,
            -Tristan
