Re: reading keyboard

[Shiraz Baig <shiraz_baig yahoo com>]

I am reading the keyboard from keypress event. But the
key read is the scan code. I need to do lot of jiggery
pokery to get the ASCII key. I am sure there must be a
function call in gtk to get the ascii key.

I need to read the key that is being typed in a text
box. But I do not want to display that key. I want to
send it over the network. When that key is echoed back
from the server then only I shall display it.
So requirement is get the ASCII key code.
