_D_e_s_c_r_i_p_t_i_o_n:

     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.) On X11 this has any effect only on X screens with a
     compositing manager running. See 'gtkWidgetIsComposited'. On
     Windows it should work always.

_U_s_a_g_e:

     gtkWindowSetOpacity(object, opacity)

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

'object': ['GtkWindow']  a 'GtkWindow'

'opacity': [numeric]  desired opacity, between 0 and 1

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

     Note that setting a window's opacity after the window has been
     shown causes it to flicker once on Windows.  

     Since  2.12
