void gtk_window_set_icon ( GtkWindow* window, GdkPixbuf* icon )
Sets up the icon representing a
GtkWindow. This icon is used when
the window is minimized (also known as iconified). Some window
managers or desktop environments may also place it in the window
frame, or display it in other contexts. On others, the icon is not
used at all, so your mileage may vary.
The icon should be provided in whatever size it was naturally drawn; that is, don’t scale the image before passing it to GTK+. Scaling is postponed until the last minute, when the desired final size is known, to allow best quality.
If you have your icon hand-drawn in multiple sizes, use gtk_window_set_icon_list(). Then the best size will be used.
This function is equivalent to calling

gtk_window_set_default_icon_list() to set the icon
for all windows in your application in one go.
