problem refreshing image widget

[amarnath bandekar <amar_bandekar yahoo co in>]

hi

i hv a program in which i have inserted an image widget in a window...i hv used g_timeout_add function to auto refresh it after particular time...but i dont kno wat should be the code of callback function (timeout_callback) so that the image in the window gets refreshed....

here is the code

 

#include<gtk/gtk.h>

#include <gdk/gdkkeysyms.h>

#include<time.h>

GtkWidget *window1;

GtkWidget *image1;

gint timeout_callback(GtkWidget *window, gpointer *data) {

free(image1);

image1=gtk_image_new_from_file("/root/thisthing.jpeg");

gtk_widget_show(image1);

g_signal_connect ((gpointer) image1, "show",

G_CALLBACK (gtk_widget_show),

NULL);

printf("hi amar\n");

}

void close_g_image(GtkWidget *window,gpointer data) {

printf("quit it\n");

gtk_main_quit();

exit(0);

}

int main(int argc, char *argv[]) {

gint tag;

gtk_set_locale ();

gtk_init (&argc, &argv);

window1 = gtk_window_new (GTK_WINDOW_TOPLEVEL);

gtk_window_set_title (GTK_WINDOW (window1), "window1");

image1 = gtk_image_new_from_file ("/root/something.jpeg");

gtk_widget_show (image1);

gtk_container_add (GTK_CONTAINER (window1), image1);

g_signal_connect ((gpointer) image1, "show",

G_CALLBACK (gtk_widget_show),

NULL);

tag=g_timeout_add(10000,GTK_SIGNAL_FUNC(timeout_callback),NULL);

g_signal_connect(GTK_OBJECT(window1),"destroy",GTK_SIGNAL_FUNC(close_g_image),window1);

gtk_widget_show (window1);

gtk_main ();

return 0;

}
