Hi. I know this is an old post, but I'm using it and it is very useful. However, I would like to know something:
Is stdout supposed to update line by line? stderr updates line by line for me, but stdout only updates all 10 lines at once. Not sure why...

I think I've found a better solution.
In the beginning of cb_child_watch () we add:

while (cb_out_watch () || cb_err_watch ());

I will test that tomorrow.

Hello,
thank you for the example, it was very useful for me :)

A little remark, if you want to run a command which outputs a lot of lines in a short time (latex, pdflatex for examples ;), we must add this code after inserting the line into the buffer:

while (gtk_events_pending ())
gtk_main_iteration ();

Without that, the result is ugly and the lines are not inserted directly.

I've encountered a strange problem with my program: cb_out_watch () is called several times (~20 times) after the call of cb_child_watch (). Maybe cb_out_watch () run too slowly and then when the command is finished, all the cb_out_watch () are not still executed.

So what I've done is to delete cb_child_watch () and the flag G_SPAWN_DO_NOT_REAP_CHILD. And I moved the instructions of cb_child_watch () into the "if( cond == G_IO_HUP )". And it works!

But maybe is there a best solution?
