     Request the windowing system to make 'window' partially
     transparent, with opacity 0 being fully transparent and 1 fully
     opaque. (Values of the opacity parameter are clamped to the [0,1]
     range.)

     gdkWindowSetOpacity(object, opacity)

_A_r_g_u_m_e_n_t_s:

'object': ['GdkWindow']  a top-level 'GdkWindow'

'opacity': [numeric]  opacity

_D_e_t_a_i_l_s:

     On X11, this works only on X screens with a compositing manager 
     running.

     For setting up per-pixel alpha, see 'gdkScreenGetRgbaColormap'.
     For making non-toplevel windows translucent, see 
     'gdkWindowSetComposited'.  

     Since  2.12
