喜欢统一通知. set_accept_focus()不是我需要的,我在gtk.gdk常量中看不到有用的东西……好像我的google-fu失败了.
所以,答案是：
win.show_all()
#win.window.input_shape_combine_mask(img,0)
def set_mask(win):
#b=gtk.gdk.bitmap_create_from_data(win.window,8,win.window.get_size())
size=win.window.get_size()
print 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)
cr.rectangle((0,0)+size)
cr.fill()
win.window.input_shape_combine_mask(bitmap,0)
print 'ready'
gobject.timeout_add(5000,set_mask,win)
