Yep, I made window that I could click through (thanks #gtk+ at irc.gnome.org), now - how to make it hear mouse_over
-event?
So, what exactly we did:
def set_mask(win):
size=win.window.get_size()
bitmap=gtk.gdk.Pixmap(win.window,size[0],size[1],1)
cr = bitmap.cairo_create()
cr.set_operator(cairo.OPERATOR_SOURCE)
cr.set_source_rgba(0.0,0.0,0.0,0.0)
cr.rectangle((0,0)+size)
cr.fill()
win.window.input_shape_combine_mask(bitmap,0,0)
