Re: Right way to tap into the main loop

[Lionel Landwerlin <llandwerlin gmail com>]

The right way to "tap" into the main loop is to add a file descriptor on which the main loop can poll.
In you case it sounds like this is exactly what you could do with the TTY's fd.

If you really need to communicate between 2 threads, just write onto one end a pipe and let the mainloop stuff poll onto the receiving end of that pipe.

Hi!

I'm using Python for this:

I'm in need of setting up a loop that checks for messages from a virtual TTY and displays the

message once it comes in. Since Clutter.main() hogs the main thread, setting up a normal thread from the main thread does nothing. Setting up a separate process circumvents this, but I see no way of

passing the message back to the main thread which has the stage handle etc.

Is it possible to use a ClutterEvent or signals for this?

I've managed to implement a working version using a time-line that signals a a check

for new messages every 0.1 seconds, but if would be way cleaner to have an actor or whatever

that emits a signal when a message is on queue.

Any takers for this? I guess really the question is how to subclass some event class and override or create a new signal method..

Kind regards,
