You'll have to run the "time-consuming function" in a separate thread or
process.

Don't run the big function in the main process. Update the progress bar in
the main process. Run the function in a child process. You could have the
child process talk to the main process over a pipe, giving he main process
updates. You can use the G_IO functions to read the pipe. It might be better
to use a thread, though.
