g_signal_connect isn't working

[Pier-Luc Charbonneau <pierluc charbonneau gmail com>]

Hi,

I'm trying to write my first gtk+ app and this snippet isn't working
(tried on 2 different computer and I tried to upgrade to the latest
gtk+)

When pressing a key in the entry:

where is psi : 134520912
where is data: 135602024
psistart *psi : 514
psistart *data: 8

When pushing the button:

where is psi : 134520912
where is data: 134520912
psistart *psi : 514
psistart *data: 514


here is the code:

#include <gtk/gtk.h>

typedef struct{
   int psistart;
   int psiend;
   int psidiff;
}PSI;

PSI *psi;

static gboolean delete_event (GtkWidget *widget, GdkEvent *event, gpointer data)
{
   gtk_main_quit();
   return FALSE;
}

static gboolean recalculate_psi_consumption(GtkWidget *widget, gpointer data)
{
   PSI *psi2;
   psi2 = (PSI *) data;
   g_print("where is psi : %i\n",psi);
   g_print("where is data: %i\n",(PSI *)data);
   g_print("psistart *psi : %i\n",((PSI*)psi)->psistart);
   g_print("psistart *data: %i\n\n\n",((PSI*)data)->psistart);
}

int main(int argc, char *argv[])
{
   psi = g_new(PSI,1);
   psi->psistart=514;
   
   gtk_init (&argc, &argv);
   GtkWidget *window;
   GtkWidget *button;
   GtkWidget *start;
   GtkWidget *table;
   
   window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
   g_signal_connect (G_OBJECT (window), "delete_event",G_CALLBACK
(delete_event), NULL);
   button = gtk_button_new_with_label("Hi!");
   table = gtk_table_new (2, 1, FALSE);
   
   gtk_container_add(GTK_CONTAINER(window),table);
   
   gtk_table_attach_defaults(GTK_TABLE(table),button,0,1,0,1);
   gtk_table_attach_defaults(GTK_TABLE(table),start = gtk_entry_new(),1,2,0,1);
   
   g_signal_connect(G_OBJECT(start),"key_press_event",G_CALLBACK(recalculate_psi_consumption),(gpointer)psi);
   g_signal_connect(G_OBJECT(button),"clicked",G_CALLBACK(recalculate_psi_consumption),(gpointer)psi);
   
   gtk_widget_show_all (window);
   
   gtk_main ();
   return 0;
}


I'm working on this bug for 9 hours I can't see why the button and the
entry are not showing the same g_print result... Crying or Very sad

My last resort is that it is a bug in gtk+ but since I'm new to gtk+ I
don't think so... (Am I wrong?)

Thank you and sorry about my english I've been coding for so long my
brain is dead,
