Variable Problem

[Wilton <wrwonrath yahoo com br>]

Hi, I'm starting to program in C/GTK+ and I have a problem with a 
variable. Let me show the code and the error:

/*-- Global Variables --*/
   char               query_string[256];
   GtkWidget     *entry_sql;
.
.
.

/*-- Do the instruction SQL --*/
   sprintf(query_string, entry_sql); // Build the instruction SQL
   res = PQexec(conn, query_string); // Send the SQL to the database

I need to pass the value in GtkWidget *entry_sql to the char 
query_string[256] (a C variable), because when i compile it i receive 
the following error:

[Warning] passing arg 2 of `sprintf' from incompatible pointer type

How can i solve this problem?

Thanks.

Wilton
