     Like 'gdkWindowShapeCombineMask', but the shape applies only to
     event handling. Mouse events which happen while the pointer
     position corresponds to an unset bit in the  mask will be passed
     on the window below 'window'.

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

     gdkWindowInputShapeCombineMask(object, mask, x, y)

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

'object': ['GdkWindow']  a 'GdkWindow'

  'mask': ['GdkBitmap']  shape mask

     'x': [integer]  X position of shape mask with respect to 'window'

     'y': [integer]  Y position of shape mask with respect to 'window'

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

     An input shape is typically used with RGBA windows. The alpha
     channel of the window defines which pixels are  invisible and
     allows for nicely antialiased borders, and the input shape
     controls where the window is "clickable".

     On the X11 platform, this requires version 1.1 of the shape
     extension.

     On the Win32 platform, this functionality is not present and the
     function does nothing.  

     Since  2.10
