Hi Jonathan,
Thanks for the reply. This was my first post in this forum as I joined the
forum today and I am happy to get a reply as in the past months I was asking
questions in gtk and gnome forums with a single or no reply at all.
I will surely look into the archive now. Actually, I am dealing with Bluetooth
sockets in this case,
best regards,
Bluezapper.

There's been some talk about threads in the last couple of weeks on this list,
you should be able to lift them from the archive if you just subscribed.
An easy alternative to threads in this case would be to connect the socket to
a GIOChannel, and have the gtk main loop deal with the data asynchronously: the
button will release immediately and the data will get processed when it gets
back.
A friend and I did this in a program we developped recently, using the gnet
library (a glib based library for portable network communication), but you
might not need that.
_very_ crudely:
gnet_tcp_socket_connect_async(adress, port,
&(_socketConnectAsyncCallback),this); // on the button clic
void _socketConnectAsyncCallback(GTcpSocket *socket,GTcpSocketConnectAsyncS
tatus status, gpointer data) is called when the connection is established (or
fails to)
then get the channel: _channel = gnet_tcp_socket_get_io_channel(socket);
register data arrival handler: g_io_add_watch(_channel, G_IO_IN,
&(_imageDataReadyForReading), this);
send your request: gnet_io_channel_write_%something
gboolean _imageDataReadyForReading(GIOChannel *, GIOCondition, gpointer data)
is called when some data arrives
VoilĂ
Hope it helps,
Jonathan

I have a question about button release event. I have a GTK_PANE window.
When I press the button I open a socket connection and get back some data from
it. Since the opening of socket and getting the data back takes some time I
want to display some status messages to the user in a text_view which is added
to the lower Pane.
My problem is until the button releases my whole application freezes and
text_view gets updated after release.
How do I start two threads in Gtk so that one thread opens the socket and other
thread updates the text_view.
Thanks for having the patience to read my long complete email,
regards,
Bluezapper.
