the second argument is the drawable, ie pixmap. the third is the GC
which can be the window style your gonna put the pixmap in. 

So you might use:

gdk_pixbuf_render_to_drawable(pixbuf, pixmap,
  window->style->fg_gc[GTK_STATE_NORMAL],
  sx,sy,dx,dy,w,h,GDK_RGB_DITHER_NORMAL,0,0);

alternatively you can create a default gc style for the pixmap and use
that for the second argument.

Hi, there,

do u mean I should use:

GtkPixmap *pixmap;

pixmap=gtk_pixmap_new();
gdk_pixbuf_render_to_drawable (pixbuf, ???,???, 0, 0,0,0, 

but how can I fill in the 2nd and 3rd arguments for
gdk_pixbuf_render_to_drawable ?

sorry, I am really new in GTK, thank you so much!
