insert_text_handler

[Jean-Philippe <soltix free fr>]

Hello,

I did find the folowing code in a documentation file (it was in C but i 
translated it to pascal and i don't remember where is the C version).

This is a callback procedure to work with the widget "entry".

The question is : It has many parameters and i don't know how to connect it 
with my entry, g_signal_connect does not accept so many parameters as i know.
Could someone send me an example please ? (in c is ok).

Thanks a lot
