with out hanging the window.

how can i do this

can you provide some example..

please help me in this way

thank you in advance

Only one thread have to own the GUI control at a time. So, if you want to access GUI from several simultaneously running threads ..... you can not do that.
The main 2 ways to solve this is to use g_add_timeout () and g_thread_enter /g_thread_leave ()

And about the example... I have no such one now but tomorrow will check my sources..
Recently I found this site. http://www.gtk-server.org/index.html
This is Gtk server and it listenes for incomming connections on basic I/O files and pipes.
It is possible to write a Gtk application without to use C/C++ or any other programming language.. just write files, type commands and the application will be created. Cool!!

HI

CAN U PLEASE HELP ME IN THIS WAY
THANK YOU IN ADVANCE

You can create threads wherever you want. Have a look about this.
http://developer.gnome.org/doc/API/2.0/glib/glib-Threads.html
The function g_thread_create creates a thread for you and calls the functions associated with that thread.
But you should remeber that you should access any object of GTK only from one thread. 2 and more threads can not access GTK. GTK is accessable only for 1 thread. Have a closer look about Glib.
Here it is. http://developer.gnome.org/doc/API/2.0/glib/index.html
