Help Regarding GNOME accessibility with our GTK based application

[venkat]

Now we are facing a peculiar problem while trying to build our 
application with GTK.

When we try to build application with threads we see that its objects 
are not accessible.
But, the same code when we try without threads we see that we are able 
to access the objects

also attached the sample codes for the same

Hope you can bring us some light in solving



#include <gtk/gtk.h>

GtkWidget* window = NULL;

gpointer main_callback(gpointer data)

        gtk_main();

        gdk_threads_init();

        /* Lock thread */
        gdk_threads_enter();

        strcat(FDKCheckScreenName, getValFromConfig("screennumber"));           
        printf("Initializing the display library\n");
    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_resize((GtkWindow*)window, 640, 480);
