#include <linux/sockios.h>
#include <string.h>
#include <math.h>

#include <fcntl.h>
#include <errno.h>
#include <unistd.h>
#include <syslog.h>

GtkWidget *filew;
GtkWidget *selection_entry;

/* Get the selected filename and print it to the console */
static void file_ok_sel( GtkWidget        *w,
                         GtkFileSelection *fs )
{
     char *file;
     file=gtk_file_selection_get_filename (GTK_FILE_SELECTION (fs));

     g_print ("%s\n",file );

  
}

static void set_selected(GtkWidget        *w,
                         GtkFileSelection *fs,
                         GtkEntry        *entry)
{
  // char *file1;
  /*  file1=gtk_file_selection_get_filename(GTK_FILE_SELECTION(filew));
    if(GTK_FILE_SELECTION (filew)->selection_entry!=NULL)
    { */   
//	gtk_widget_set_sensitive(G_OBJECT (GTK_FILE_SELECTION (filew)->ok_button),TRUE);
    //}  
    
    char *file1;
   // file1=gtk_file_selection_get_filename(GTK_FILE_SELECTION(fs));
   // gtk_entry_set_text (GTK_FILE_SELECTION (filew)->selection_entry,file1);

   file1=gtk_entry_get_text (GTK_FILE_SELECTION (fs)->selection_entry);
     g_print ("file1 = %s\n",file1 );

}

int main( int   argc,
          char *argv[] )
{
    //GtkWidget *filew;
    
    gtk_init (&argc, &argv);
    
    /* Create a new file selection widget */
    filew = gtk_file_selection_new ("File selection");
    
    g_signal_connect (G_OBJECT (filew), "destroy",
	              G_CALLBACK (gtk_main_quit), NULL);
    /* Connect the ok_button to file_ok_sel function */
    g_signal_connect (G_OBJECT (GTK_FILE_SELECTION (filew)->ok_button),
		      "clicked", G_CALLBACK (file_ok_sel), (gpointer) filew);

   /* Ensure that the dialog box is destroyed when the user clicks a button. */
    g_signal_connect_swapped (GTK_FILE_SELECTION (filew)->ok_button,
                             "clicked",
                             G_CALLBACK (gtk_widget_destroy), 
                             (gpointer) filew);


    gtk_widget_set_sensitive(G_OBJECT (GTK_FILE_SELECTION (filew)->ok_button),FALSE); 
    
    /* Connect the cancel_button to destroy the widget */
    g_signal_connect_swapped (G_OBJECT (GTK_FILE_SELECTION (filew)->cancel_button),
	                      "clicked", G_CALLBACK (gtk_widget_destroy),
			      G_OBJECT (filew));

    g_signal_connect(G_OBJECT(GTK_FILE_SELECTION (filew)->selection_entry), "insert_text",
		     G_CALLBACK(set_selected),
		     G_OBJECT (filew)); 


    /* Lets set the filename, as if this were a save dialog, and we are giving
     a default filename */
    gtk_file_selection_set_filename (GTK_FILE_SELECTION(filew), 
				     " ");

    // gtk_file_selection_hide_fileop_buttons(GTK_FILE_SELECTION(filew));

    gtk_widget_show (filew);
    gtk_main ();
    return 0;
}
