I made a test program ... this is flicker-free for me (gtk+-2.4.14,
linux). Click a button to add more buttons.
#include <stdio.h>
#include <gtk/gtk.h>
void
add_buttons (void *dummy, GtkWidget * fixed)
{
static int button_number = 0;
int i;
for (i = 0; i < 100; i++)
{
GtkWidget *but;
char buf[256];
snprintf (buf, 256, "Button %d", button_number++);
but = gtk_button_new_with_label (buf);
gtk_fixed_put (GTK_FIXED (fixed), but,
random () % 1000, random () % 1000);
g_signal_connect (but, "clicked", G_CALLBACK (add_buttons), fixed);
gtk_widget_show (but);
}
}
int
main (int argc, char **argv)
{
GtkWidget *window;
GtkWidget *fixed;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
fixed = gtk_fixed_new ();
gtk_container_add (GTK_CONTAINER (window), fixed);
gtk_widget_show_all (window);
add_buttons (NULL, fixed);
gtk_main ();
return 0;
}
