Please don't cross-post in the future.

You need the gdk pixmap created at the same depth as the gdk window
it is to be drawn into.  Do this:

  gtk_widget_realize(window);
  pmap = gdk_pixmap_create_from_data (window->window,
                                      Small_Bit.bitmap,
                                      Small_Bit.cols,
                                      Small_Bit.rows,
                                      -1,
                                      &white,
                                      &black);

Using -1 in the depth field tells the function to use the value
from the window that is passed in, and if you do not realize the
window first then you are passing in NULL.

Good luck,
