Ok, I understand.
But I even tried the same thing with thread, where the inter-process communication is happening in one thread and the gui is in another thread. I hoped threading would be able to handle the scenario but it could not. As I have explained earlier in this post, the client is sending data with usleep(some number) interval of time, the server reads the data and writes that into a shared variable. The gui thread reads from that shared variable and invokes the relevant gui updateDisplay() routine to update the gui.
But this also not bringing things up if the usleep is very small amount of time and I am trying to change some 1k rows every millisecond. But how can not threading the handle this problem ? Why this gui is not responding ?
